Question 1
A technician is troubleshooting an all-in-one laser printer that prints a vertical line when making copies and scans. When users print or receive faxes, the output from the printer is correct. Which of the following should the technician examine to determine the cause of the issue?
Show answer and explanation
Correct answer: C. The document feeder
The vertical line appears only during copying and scanning, not during printing or faxing. This indicates the issue is with the document feeder path, which is used only when scanning or copying documents. The document feeder's rollers or guides would cause a consistent vertical line to appear on the scanned/copied output. Since normal printing and faxing work correctly, the issue is isolated to the input mechanism rather than the imaging drum or corona wire.
Why the other options are wrong
- A. Pickup rollers feed paper from the tray during printing, but the issue doesn't affect printed or faxed output.
- B. Corona wire issues would affect all imaging processes including printing and faxing, which work correctly here.
- D. Drum assembly problems would cause defects in all output modes, but printing and faxing are unaffected.
Question 2
Which of the following is an advantage of using a hybrid cloud instead of a public cloud?
Show answer and explanation
Correct answer: C. Ability to meet data residency requirements
A hybrid cloud architecture allows organizations to keep sensitive data on private infrastructure while leveraging public cloud resources, enabling them to meet data residency and regulatory requirements that mandate data remain within specific geographic regions or under direct organizational control. This is a primary advantage over pure public cloud solutions where all data is hosted on the provider's infrastructure.
Why the other options are wrong
- A. Hybrid cloud typically increases management overhead compared to public cloud due to managing both private and public environments.
- B. Cross-platform virtualization is not inherently tied to hybrid cloud architecture and can be used in any cloud model.
- D. Both public and hybrid clouds can leverage IaaS and PaaS; this is not a distinguishing advantage of hybrid cloud.
Question 3
A technician is troubleshooting a desktop PC that is plugged into a UPS. The PC loses the system date/time after every power outage. Which of the following should the technician do to resolve the issue? (Choose two.)
Show answer and explanation
Correct answer: D, E. Repair the backup power source; Replace the CMOS battery.
The CMOS battery maintains the system's real-time clock and BIOS settings during power outages. When it fails, the system loses date/time information after each power loss, even with a UPS protecting the system. Additionally, if the UPS backup power source is faulty and not actually providing power to maintain the CMOS battery during outages, the issue persists. Replacing the CMOS battery and repairing the UPS backup power source addresses both potential causes.
Why the other options are wrong
- A. A BIOS update would not restore CMOS battery functionality or fix a depleted battery.
- B. RAM issues do not affect the system clock; RAM is volatile memory that doesn't store date/time between shutdowns.
- C. Disabling NTP would prevent automatic time synchronization but wouldn't resolve the underlying CMOS battery failure.
- F. A surge protector is redundant with a UPS and wouldn't address the clock loss issue after power outages.
Question 4
A network administrator must ensure that a printer will still be assigned a specific IP address even if all addresses are depleted. Which of the following network configuration concepts is this describing?
Show answer and explanation
Correct answer: C. Reservation
A DHCP reservation ensures a specific device receives the same IP address each time it connects to the network, even when the address pool is depleted. This is accomplished by marking specific MAC addresses to always receive predetermined IP addresses outside the normal lease allocation process, guaranteeing the printer always has a consistent IP regardless of overall address availability.
Why the other options are wrong
- A. VLANs segment networks logically but don't guarantee specific IP address assignment to devices.
- B. A lease is a temporary assignment with an expiration time; it doesn't ensure permanent address retention when the pool is exhausted.
- D. An exclusion removes addresses from the pool so they won't be assigned, the opposite of what's needed to guarantee a specific address.
Question 5
A user is having issues when charging a device with a Lightning cable. The cable is not recognized when it is plugged into the device. This issue is usually resolved by flipping the cable over. This issue does not occur with other devices of the same type. Which of the following would most likely cause the issue?
Show answer and explanation
Correct answer: D. The charging port is dirty or damaged
Lightning connectors are reversible by design, so the need to flip the cable to establish recognition indicates a physical port problem. The charging port is likely dirty (debris preventing proper contact) or internally damaged (bent or misaligned pins/contacts). Since the issue is specific to this one device and doesn't occur with other identical devices, it's a hardware defect in the port, not the cable itself.
Why the other options are wrong
- A. A restart wouldn't resolve a hardware charging port recognition issue; the port either makes contact or it doesn't.
- B. A swelling battery would prevent charging entirely, not cause intermittent recognition based on cable orientation.
- C. If the cable were failing, flipping it wouldn't reliably resolve the issue, and the problem would likely occur with other devices too.
Question 6
Which of the following servers is used to collect data and information about events from a network-connected host?
Show answer and explanation
Correct answer: D. Syslog
A Syslog server is specifically designed to collect, aggregate, and store log data and event information from network devices and hosts. It provides centralized logging for monitoring system events, errors, and diagnostic information across the network infrastructure.
Why the other options are wrong
- A. DNS servers translate domain names to IP addresses; they don't collect event data.
- B. Mail servers handle email transmission and storage, not network event logging.
- C. Print servers manage printer resources and job queues, not system event collection.
Question 7
A technician observes slow startup times on a laptop. Which of the following is most likely causing the issue?
Show answer and explanation
Correct answer: A. HDD
Slow startup times are most commonly caused by a failing or aging hard disk drive (HDD). HDDs have mechanical components that degrade over time, resulting in slow read/write operations during the boot process. An SSD would dramatically improve startup times, making HDD replacement the most effective solution for this symptom.
Why the other options are wrong
- B. RAM affects overall system responsiveness and multitasking performance, but insufficient RAM doesn't typically cause slow startup times.
- C. Network interface card issues would affect network connectivity, not system startup speed.
- D. BIOS speed doesn't significantly impact overall startup duration; BIOS execution is a small fraction of boot time.
Question 8
A customer reports their tablet was recently dropped on the ground. The tablet has a small crack in one corner of the display, and it does not charge when plugged in. Which of the following should a technician do first?
Show answer and explanation
Correct answer: C. Inspect the USB-C port for damage.
After a drop, the tablet fails to charge, indicating potential physical damage to the charging port. The USB-C port should be inspected first for debris, bent pins, or internal damage that would prevent proper connection and power transfer. This is the most direct cause of the charging failure and should be examined before attempting repairs that might mask a more serious underlying issue.
Why the other options are wrong
- A. A hard restart won't resolve a hardware charging port issue; the problem is physical, not software.
- B. Battery replacement is premature before determining if the port itself is damaged and preventing charge detection.
- D. Digitizer diagnostics address the display's touch functionality, not the charging failure symptom.
Question 9
A technician needs to select PC components with a minimal number of visible internal cables. Which of the following should the technician use?
Show answer and explanation
Correct answer: C. Modular power supply
A modular power supply allows technicians to connect only the necessary cables, leaving unused cables disconnected and hidden, thereby minimizing visible internal cabling. SATA drives still require visible cables, liquid cooling systems have visible tubes and fittings, and wireless NICs don't address internal cable visibility.
Why the other options are wrong
- A. SATA drives still require visible data and power cables to connect to the motherboard and power supply.
- B. Liquid cooling systems include visible radiators, tubes, and hoses that add to internal cable clutter.
- D. A wireless NIC addresses network connectivity, not the number of visible internal cables.
Question 10
A user is traveling internationally. They can make and receive phone calls but cannot send or receive email. Which of the following would most likely resolve this issue?
Show answer and explanation
Correct answer: B. Enabling data roaming
Email requires data connectivity, while calling uses voice services. When traveling internationally, data roaming must be explicitly enabled to access cellular data networks needed for email. The user can make calls because voice services may operate differently than data, but email cannot function without active data connectivity.
Why the other options are wrong
- A. Disabling GPS has no effect on email or data connectivity capabilities.
- C. Configuring 4G usage only doesn't address whether data roaming is enabled; it may actually limit connectivity if 4G isn't available.
- D. Using a hotspot requires the device to already have data connectivity, which is the underlying problem being addressed.

Question 11
Which of the following is designed for interaction to take place via an OS running on the host rather than the host directly?
Show answer and explanation
Correct answer: B. Type 2 hypervisor
A Type 2 hypervisor runs on top of a host operating system rather than directly on hardware. Guest virtual machines interact through the host OS instead of directly with the physical hardware, making the host OS an intermediary layer.
Why the other options are wrong
- A. Type 1 hypervisors run directly on bare metal hardware without a host OS, so interaction does not take place via an OS.
- C. Elasticity is a cloud computing characteristic related to scaling resources, not a hypervisor type.
- D. Multitenancy describes the sharing of resources among multiple users or organizations, not the architectural design of how hypervisors interact with operating systems.
Question 12
Which of the following types of RAM would most likely be used in a server?
Show answer and explanation
Correct answer: B. ECC
ECC (Error-Correcting Code) RAM is the standard for servers because it detects and corrects single-bit memory errors, ensuring data integrity and system reliability. Servers require this protection due to their mission-critical nature and continuous operation, making ECC the most appropriate choice for server environments.
Why the other options are wrong
- A. SODIMM is a small form factor RAM used in laptops and compact devices, not servers.
- C. Unbuffered RAM lacks error correction and is typically found in consumer-grade systems, not servers.
- D. DDR3 is a speed/generation designation that can apply to any RAM type; ECC DDR3 exists, but DDR3 alone does not indicate server-grade memory.
Question 13
Which of the following uses a small and portable private network to allow multiple wireless devices to share an internet connection?
Show answer and explanation
Correct answer: B. Hotspot
A hotspot is a small, portable device or feature that creates a private wireless network (often called a personal hotspot or mobile hotspot) allowing multiple wireless devices to connect to and share a single internet connection, typically from a smartphone or dedicated hotspot device.
Why the other options are wrong
- A. Bluetooth is a wireless technology for short-range communication but is not designed as a primary mechanism for sharing internet connections across multiple devices.
- C. Tethering is the process of connecting one device to another to share internet, but it's not itself a network type and typically refers to using a cable or USB connection rather than a portable wireless network.
- D. NFC (Near Field Communication) is for very short-range communication and payments, not for creating networks to share internet connections.
Question 14
A customer reports that a workstation has no internet connectivity. A technician confirms the port is disabled. Which of the following is most likely responsible for the issue?
Show answer and explanation
Correct answer: C. Managed switch
A managed switch is responsible for enabling or disabling network ports. If a technician confirms a port is disabled, the managed switch is most likely the cause, as administrators can selectively disable ports at the switch level. A patch panel is passive, a NIC failure would be a hardware issue, and a firewall typically blocks traffic rather than disabling physical ports.
Why the other options are wrong
- A. A patch panel is a passive component that simply connects cables; it cannot disable ports.
- B. A physical NIC failure would cause hardware issues but would not result in a disabled port setting.
- D. A firewall blocks traffic but does not disable the physical network port itself.
Question 15
An IT specialist sets up a new computer for a user who requires a high-end video card and the fastest hard drive possible. Which of the following connectors should the specialist verify are available on the motherboard? (Choose two.)
Show answer and explanation
Correct answer: B, F. NVMe; PCIe
For a high-end video card and fastest storage, the specialist needs to verify NVMe (M.2) slots for the fastest SSDs and PCIe slots (typically PCIe x16) for the high-end video card. NVMe drives connect via M.2 slots on the motherboard and offer the fastest storage performance. PCIe slots are essential for installing discrete graphics cards. Both are critical for this user's requirements.
Why the other options are wrong
- A. Molex connectors are legacy power connectors; modern components use SATA power or direct motherboard connections.
- C. SATA is slower than NVMe and is not the fastest hard drive option available.
- D. FireWire is an outdated external connector not relevant to internal component installation.
- E. USB-C is an external connector standard, not a motherboard slot for internal components like video cards or storage.
Question 16
An employee’s screen keeps flashing. Sometimes the picture goes out and comes back. The employee checks the power cord and confirms the device is plugged in fully. Which of the following should a technician check for first?
Show answer and explanation
Correct answer: A. Loose video cable
Intermittent screen flashing with periodic signal loss is a classic symptom of a loose video cable connection. Since the power cord has been verified, checking the video cable connection to both the monitor and graphics card (or motherboard) is the quickest and most common fix for this type of intermittent display issue.
Why the other options are wrong
- B. A failing graphics card typically produces consistent artifacts or complete failure, not intermittent flashing.
- C. Conflicting drivers would cause performance issues or crashes rather than periodic signal loss from the display.
- D. A swollen capacitor is a hardware defect that would cause system instability or failure, not specifically intermittent display flashing.
Question 17
Which of the following DNS records displays the destination of incoming email on a domain?
Show answer and explanation
Correct answer: C. MX
An MX (Mail Exchange) record in DNS specifies the mail server responsible for receiving email messages on behalf of a domain. When someone sends an email to an address at a domain, the sender's mail server queries the MX record to determine where to deliver the message. This record is essential for directing incoming mail to the correct mail server infrastructure.
Why the other options are wrong
- A. CNAME (Canonical Name) records are used to create aliases for domain names, not for email routing.
- B. TXT records are used for text-based information such as SPF, DKIM, and DMARC authentication records, not for specifying mail server destinations.
- D. AAAA records map domain names to IPv6 addresses for general network connectivity, not for email delivery.
Question 18
A user would like to connect a laptop to a monitor, keyboard, and mouse when in the office. The user prefers to use as few cables as possible. Which of the following would best achieve that goal?
Show answer and explanation
Correct answer: C. Docking station
A docking station connects to a laptop via a single cable and provides connections for monitor, keyboard, mouse, and other peripherals, requiring the fewest cables overall. Bluetooth and NFC are wireless but would still require separate connections for each device, and a managed switch provides network connectivity only.
Why the other options are wrong
- A. Bluetooth would require pairing each device separately and does not connect a monitor.
- B. A managed switch provides only network connectivity, not monitor, keyboard, or mouse connections.
- D. Near-field communication has very limited range and bandwidth, unsuitable for peripheral connections.
Question 19
A technician is working on a RAID 1 array that is apparently degraded. The technician verifies the RAM and power are both operating as expected. Which of the following can the technician do to further isolate the issue?
Show answer and explanation
Correct answer: A. Perform individual drive diagnostics.
Performing individual drive diagnostics is the appropriate next step to isolate which specific drive in the RAID 1 array is failing. Since RAM and power are confirmed working, testing each drive will identify the degraded component without making assumptions or taking corrective action prematurely.
Why the other options are wrong
- B. Running chkdsk /f attempts to repair the file system but does not diagnose the underlying hardware issue causing the degradation.
- C. Rebuilding the array should not be done until the technician identifies which drive has failed; rebuilding prematurely could cause data loss.
- D. Reconfiguring as RAID 0 removes all redundancy and would result in data loss if any drive fails.
Question 20
Which of the following network services is used to assign an IP address to a network host?
Show answer and explanation
Correct answer: A. DHCP
DHCP (Dynamic Host Configuration Protocol) is specifically designed to automatically assign IP addresses to network hosts. DNS resolves domain names to IP addresses, LDAP is a directory service, and SMTP handles email transmission, none of these assign IP addresses.
Why the other options are wrong
- B. DNS resolves hostnames to IP addresses but does not assign them.
- C. LDAP is a directory service protocol used for authentication and directory lookups.
- D. SMTP is an email transmission protocol and has no role in IP address assignment.
Question 21
Which of the following statements best summarize managed vs unmanaged switches? (Choose two.)
Show answer and explanation
Correct answer: C, D. Unmanaged switches start working as soon as they are plugged in to the network; Managed switches have more features
Unmanaged switches are plug-and-play devices that require no configuration and function immediately when powered on, making option C correct. Managed switches offer advanced features such as VLAN support, port mirroring, QoS, and security controls that unmanaged switches lack, making option D correct. Managed switches are typically more expensive and require configuration, contradicting options A, B, and E. Option F is incorrect as managed switches often consume more power due to additional processing.
Why the other options are wrong
- A. Unmanaged switches are generally less expensive than managed switches.
- B. Unmanaged switches have minimal to no security capabilities; managed switches provide security features.
- E. Managed switches require configuration to function optimally, not zero configuration.
- F. Managed switches typically consume more power due to processing overhead, not less.
Question 22
Which of the following should be used when installing network cabling above a drop ceiling that is part of the shared air space?
Show answer and explanation
Correct answer: B. Plenum-rated
Plenum-rated cabling is specifically designed for use in plenum spaces, the shared air space above drop ceilings used for ventilation and air circulation. These cables use fire-retardant materials that produce minimal smoke and toxic fumes if they burn, meeting building codes and safety regulations for these critical spaces.
Why the other options are wrong
- A. Shielded twisted pair addresses electromagnetic interference but has no special fire-safety rating for plenum use.
- C. Optical fiber doesn't require plenum-rating; it's used for long-distance high-speed connections, not typically overhead runs.
- D. Coaxial cable is rarely used for modern network installations and has no plenum-rating certification.
Question 23
A technician recently updated the firmware on a dual-BIOS motherboard. Following the update, the system has been stuck in a boot loop and cannot start an OS from any internal or external device. The technician cannot access the UEFI menu either. Which of the following should the technician do next?
Show answer and explanation
Correct answer: A. Enable the secondary configuration.
A dual-BIOS motherboard has a primary and secondary BIOS chip specifically designed for recovery scenarios. When a firmware update fails and corrupts the primary BIOS to the point where the UEFI menu is inaccessible and the system cannot boot, enabling the secondary BIOS configuration is the recovery method built into the motherboard design to restore functionality.
Why the other options are wrong
- B. Downgrading firmware via USB would require accessing the UEFI menu or a recovery interface, which is not available in this scenario.
- C. Warranty repair is premature when a dual-BIOS motherboard's recovery feature is available and designed for exactly this situation.
- D. Reapplying thermal paste has no relevance to a firmware corruption issue and would not resolve the boot loop problem.
Question 24
Which of the following tools would a technician use to connect wires to an RJ45 connector?
Show answer and explanation
Correct answer: A. Crimper
A crimper is the specialized tool used to attach wires to an RJ45 connector by compressing the connector onto the wires to create the proper electrical and mechanical connection. This is the standard tool for terminating twisted-pair Ethernet cables.
Why the other options are wrong
- B. A cable stripper removes the outer jacket of cables but does not attach wires to connectors.
- C. A punchdown tool is used to insert wires into punchdown blocks or keystone jacks, not to crimp RJ45 connectors.
- D. A loopback plug is a testing device used to verify network port functionality, not a tool for creating connections.
Question 25
Which of the following is the best to use when testing a file for potential malware?
Show answer and explanation

Show answer and explanation
Correct answer: B. Mobile device management
Mobile Device Management (MDM) is the service responsible for enforcing security policies, certificates, and access controls on mobile devices. When a user cannot access secure applications remotely but can in the office, the MDM policy likely needs to be reconfigured to allow remote access or to properly provision security certificates and authentication for off-network connections. MDM controls which apps can run and enforces security requirements for application access.
Why the other options are wrong
- A. GPS is used for location services and has no relationship to accessing secure applications.
- C. Wi-Fi Protected Access (WPA) is a network security standard and would affect all network access equally, not just secure applications.
- D. Near-field communication (NFC) is a short-range wireless technology and has no relevance to accessing secure enterprise applications.

Why the other options are wrong
- A. Cellular location services are for mobile device positioning, not office network resource access.
- C. Bluetooth connectivity has limited range and is not suitable for reliable office-wide network resource access.
- D. Roaming profiles manage user settings and data across networked computers but do not address wireless connectivity within an office.
Question 28
Which of the following utilizes specialized ports on a laptop to expand the local connection options?
Show answer and explanation
Correct answer: B. Docking station
A docking station utilizes specialized ports on a laptop to expand local connection options by providing additional USB ports, network connections, video outputs, and other peripherals. While a port replicator also expands connections, docking stations are the primary technology designed for this purpose and offer more comprehensive expansion capabilities.
Why the other options are wrong
- A. NFC adapters enable wireless near-field communication but do not expand local connection options.
- C. Port replicators do expand connections but are less commonly referenced as the standard answer for this function compared to docking stations.
- D. USB dongles are passive adapters that convert one connector type to another but do not expand the overall number of connection options available.
Question 29
Which of the following is a common feature of managed switches?
Show answer and explanation
Correct answer: B. Port VLAN assignment
Port VLAN assignment is a standard feature of managed switches, allowing administrators to assign specific ports to different virtual LANs for network segmentation and traffic control. This is a core management capability that distinguishes managed switches from unmanaged ones.
Why the other options are wrong
- A. Remote device power delivery is not a standard managed switch feature; that's typically a PoE injector capability.
- C. Content filtering is a firewall or application-layer feature, not a typical managed switch function.
- D. Load balancing is typically handled by dedicated load balancers or routers, not standard managed switches.
Question 30
After a technician installs a new motherboard, the computer will not start and fails POST. The technician verifies the power supply is functioning as expected, and the CPU is installed correctly. Which of the following steps should the technician complete next?
Show answer and explanation
Correct answer: C. Reseat the RAM.
After verifying the power supply and CPU installation, RAM is the next most common cause of POST failures on a new motherboard installation. RAM modules can appear properly seated but have poor contact, and reseating them often resolves no-boot issues. This is a quick, non-destructive troubleshooting step that should be attempted before more invasive measures like BIOS flashing or motherboard replacement.
Why the other options are wrong
- A. BIOS flashing should only be attempted after basic hardware troubleshooting and is not a first-line response to POST failures.
- B. While CMOS battery issues can cause problems, they typically result in incorrect system time or boot settings rather than complete POST failures on new installations.
- D. Reinstalling the old motherboard is a last resort only after confirming the new motherboard is defective, not an early troubleshooting step.
Question 31
An end user reports that their laptop shuts down when they undock it. Even when using a new charging cable, the issue persists. Which of the following should the technician do next?
Show answer and explanation
Correct answer: D. Replace the battery
A laptop shutting down upon undocking despite using a new charging cable points to a battery issue. The system likely requires minimum power from the battery to remain stable during the docking transition. A faulty battery cannot hold charge and triggers a critical power event, causing shutdown. Since a new cable didn't resolve it, the battery itself is the failing component.
Why the other options are wrong
- A. BIOS flashing is not a standard troubleshooting step for power-related issues and could cause data loss.
- B. Driver updates may help with power management but wouldn't address a failing battery.
- C. A different charger has functionally been tested with the new cable; the issue persists regardless of charging equipment.
Question 32
A computer is experiencing random shutdowns. A technician notices that the fans on the computer work but are noisy. The CPU temperature is about 122°F (50°C) when the computer is started but rises to 208°F (98°C) when applications are opened. Which of the following would most likely fix this issue?
Show answer and explanation
Correct answer: B. Installing a high-performance heat sink
The CPU temperature climbing to 98°C under load indicates inadequate heat dissipation from the CPU to the cooling system. While the fans are running (though noisy), a better heat sink with improved thermal conductivity and surface area would transfer heat more efficiently from the CPU to the fans. This addresses the thermal bottleneck causing random shutdowns due to thermal throttling or emergency shutoffs.
Why the other options are wrong
- A. The power supply is not related to CPU temperature issues; random shutdowns from heat are thermal, not power-related.
- C. Fan settings adjustment won't help if the heat sink itself isn't transferring heat adequately to the fans.
- D. Adding RAM does not affect CPU cooling or thermal management.
Question 33
A network printer does not release a user's final print job from the queue, but the user's other print jobs successfully printed a few moments before. Other users can print without issues. Which of the following should the user check first to solve the issue?
Show answer and explanation
Correct answer: A. If the print job is configured to a tray or manual feed
When a specific print job fails to release from the queue while other jobs printed successfully, the issue is typically related to that particular job's configuration. A job configured to a specific tray or manual feed setting that is unavailable will remain stuck in the queue. This is the first troubleshooting step because it's job-specific and explains why other users and earlier jobs were successful.
Why the other options are wrong
- B. Network connectivity is unlikely since other print jobs from the same user succeeded moments before, indicating the connection is functional.
- C. A full print queue would prevent new jobs from being accepted, but this user's other jobs already printed, so the queue is functioning.
- D. Empty trays would prevent all jobs from printing or would have stopped the previous jobs; earlier jobs from this user printed successfully.
Question 34
A user tries to connect a monitor to a laptop to have an additional screen for work, but both screens show the same content. Which of the following should the user do to resolve the issue?
Show answer and explanation
Correct answer: D. Go to the Display settings and configure the external monitor as extended.
When a monitor shows the same content as the laptop screen, it's configured in mirror/duplicate mode rather than extended mode. To use the monitor as an additional screen, the user must access Windows Display settings and configure the external monitor as an extended display, which will allow them to use both screens for different content simultaneously.
Why the other options are wrong
- A. Hardware assistants are not needed for modern monitors; display configuration is handled through OS settings.
- B. A docking station is not required to resolve this issue; the monitor is already connected and recognized.
- C. Windows tiling arranges windows on existing displays but does not change the display mode from mirrored to extended.
Question 35
A user reports slow performance when saving documents locally on a computer. A technician reviews the logs and notices entries showing S.M.A.R.T. errors. Which of the following actions should the technician take next?
Show answer and explanation
Correct answer: B. Replace the hard drive.
S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) errors indicate imminent or actual hard drive failure. When S.M.A.R.T. errors appear in logs, the drive is experiencing mechanical or electrical degradation and should be replaced before complete failure occurs and data is lost. This is the only appropriate action to prevent further data corruption and system failure.
Why the other options are wrong
- A. Reseating SATA cables addresses connection issues, not the drive failure indicated by S.M.A.R.T. errors.
- C. Defragmentation can worsen performance on a failing drive and does not address the underlying hardware failure.
- D. Disk Cleanup removes unnecessary files but does not resolve S.M.A.R.T. errors or hardware failure.
- E. A heat sink does not fix S.M.A.R.T. errors; the drive hardware is failing at the component level.
Question 36
Which of the following ports is commonly used for remote desktop connections?
Show answer and explanation
Correct answer: C. 3389
Port 3389 is the standard port for Remote Desktop Protocol (RDP), which enables remote desktop connections. Port 137 is used for NetBIOS, port 445 for SMB/CIFS file sharing, and port 4443 is sometimes used for HTTPS or other secure services, but none are standard for remote desktop.
Why the other options are wrong
- A. Port 137 is associated with NetBIOS name resolution, not remote desktop.
- B. Port 445 is used for SMB/CIFS file sharing and network communications.
- D. Port 4443 is sometimes used as an alternate HTTPS port but not for standard remote desktop.
Question 37
An office is experiencing frequent wireless outages and slow network speeds. A technician confirms that all wireless devices are experiencing the same symptoms. Which of the following should the technician do to determine whether the issue is external or internal?
Show answer and explanation
Correct answer: C. Connect a machine using Ethernet and test connectivity.
To determine whether a wireless outage is caused by an internal network issue or external/environmental factors, the technician should connect a device via Ethernet cable and test connectivity. If the Ethernet connection works properly, the issue is wireless-specific (internal). If Ethernet also fails, the problem is upstream (external or broader network infrastructure).
Why the other options are wrong
- A. Restarting devices and checking workgroup membership does not isolate whether the problem is wireless-specific or external.
- B. Checking DNS configuration is part of general network troubleshooting but doesn't specifically distinguish between wireless and external issues affecting all wireless devices equally.

- D. Disabling the default gateway is not a standard remediation for printer vulnerabilities and would impair device functionality.
Question 62
A high-end workstation with a RAID 5 array is exhibiting slow data access speeds and occasional errors when retrieving files. The technician investigates further and notices one of the hard drives in the RAID array has an amber light. Which of the following steps should the technician take to troubleshoot and resolve the issues?
Show answer and explanation
Correct answer: C. Replace the failing drive, and then allow the RAID controller to rebuild the array.
When a drive in a RAID 5 array shows an amber light, this indicates a failing or failed drive. The correct procedure is to replace the failing drive and allow the RAID controller to rebuild the array using the parity information stored across the remaining drives. RAID 5 can tolerate one drive failure, and the rebuild process will restore full redundancy and resolve both the slow speeds and errors caused by the degraded array state.
Why the other options are wrong
- A. Network issues would not cause hard drive indicator lights to turn amber or directly cause file retrieval errors from the RAID array.
- B. Upgrading all drives is unnecessary and wasteful; only the failing drive needs replacement, and higher capacity does not address the current failure.
- D. Reformatting all drives would destroy data and is inappropriate; the RAID controller is designed to recover from single drive failures automatically.

Question 79
Users have noticed their devices are frequently disconnecting or experiencing slow speeds in the company lobby, but the Wi-Fi signal is strong. Which of the following is the first step to troubleshoot the issue?
Show answer and explanation
Correct answer: B. Inspect the area for possible sources of interference or physical obstructions that could be disrupting the signal.
When strong signal exists but performance is poor, the first diagnostic step is to identify environmental factors causing interference or obstruction, not to make expensive infrastructure changes. Problems like microwave ovens, cordless phones, metal structures, or physical objects between client and access point are common culprits. Only after ruling out interference should you consider hardware upgrades, frequency changes, or architectural modifications.
Why the other options are wrong
- A. Adding access points addresses signal strength, but the user already reports a strong signal, so this expensive solution is premature.
- C. Recommending wired connections circumvents the problem rather than troubleshooting it and reduces mobility.
- D. Changing frequencies should only be attempted after identifying that interference is the root cause, not as a first step.
Question 80
Which of the following internet connection types provides the fastest speeds and greatest coverage in less populated areas with minimal infrastructure?
Show answer and explanation
Correct answer: D. Cellular
Cellular networks provide the greatest coverage in less populated areas with minimal infrastructure because they rely on distributed cell towers rather than hardwired infrastructure. While cellular speeds may not always match fiber in urban areas, it offers the best combination of speed and coverage for remote and sparsely developed regions where fiber, cable, and DSL infrastructure is unavailable.
Why the other options are wrong
- A. Fiber requires extensive underground or aerial infrastructure that is not economical in less populated areas.
- B. Cable requires hardwired infrastructure (coaxial lines) that is not deployed in rural areas.
- C. DSL requires proximity to telephone lines and is unavailable in many less populated regions.
Question 81
Every day for a week, when a user turns on their computer, the time is wrong. A technician corrects the time, but the issue happens again. Which of the following is most likely the cause of the issue?
Show answer and explanation
Correct answer: D. A faulty CMOS battery
The CMOS battery maintains the system time when the computer is powered off. A failing CMOS battery loses its charge and cannot retain the time, causing the system clock to reset each time the device powers on. NTP settings affect network time synchronization but wouldn't cause this recurring daily issue, and time zone settings would not reset each day.
Why the other options are wrong
- A. A failing NIC would affect network connectivity, not the system clock.
- B. Misconfigured NTP would cause continuous time drift if enabled, not daily resets at startup.
- C. An incorrect time zone would display the wrong time consistently but not reset daily to an earlier time.
Question 82
Which of the following best characterizes a plenum-rated cable?
Show answer and explanation
Correct answer: A. Resistant to fire
Plenum-rated cable is specifically designed to be fire-resistant and low-smoke producing, making it safe for use in plenum spaces (air return pathways in buildings). The plenum rating is a fire safety classification that ensures the cable meets strict fire codes and won't release toxic fumes when exposed to heat or flame.
Why the other options are wrong
- B. EMI shielding is a separate cable characteristic unrelated to plenum rating; plenum cable may or may not have EMI protection.
- C. Plenum-rated cable is specifically for internal building spaces (plenums), not external installations.
- D. Data transmission speed is independent of plenum rating and has no bearing on fire resistance properties.
Question 83
Which of the following is used to reduce cabling requirements to specific security cameras?
Show answer and explanation
Correct answer: A. PoE
Power over Ethernet (PoE) reduces cabling requirements by delivering both power and data over a single Ethernet cable to security cameras, eliminating the need for separate power cabling. DSL is a broadband technology, ONT is for fiber networks, and NIC is a network adapter, none reduce cabling requirements for cameras specifically.
Why the other options are wrong
- B. DSL is a broadband internet connection technology and does not reduce camera cabling requirements.
- C. ONT (Optical Network Terminal) is used in fiber installations but does not specifically reduce security camera cabling.
- D. NIC is a network interface card component and does not provide power delivery or reduce overall cabling.
Question 84
Which of the following is related to the creation of a secured communication channel between workstations in different locations and is supported by credentials for authentication?
Show answer and explanation
Correct answer: D. VPN
A VPN (Virtual Private Network) creates a secured communication channel between remote workstations or networks by encrypting data and routing it through a secure tunnel. VPNs use credentials for authentication to verify the identity of users or devices before establishing the secure connection. This technology allows secure communication over untrusted networks like the internet between different physical locations.
Why the other options are wrong
- A. DHCP is a protocol for automatic IP address assignment, not for creating secured communication channels.
- B. CNAME is a DNS record type used for domain aliasing, not for secured communication channels.
- C. VLAN is a network segmentation technology that creates logical networks on a single physical switch, not secured channels between different locations.
Question 85
An engineer must implement a solution to facilitate and maintain an organization's legacy application until it is retired. The application is currently hosted on three physical servers. Which of the following is the most suitable concept for this purpose?
Show answer and explanation
Correct answer: C. Virtualization
Virtualization is the most suitable concept for maintaining legacy applications on existing hardware. It allows the three physical servers to be consolidated or replicated as virtual machines, reducing infrastructure costs while preserving the application until retirement. SAN is storage-focused, FaaS is for serverless functions, and configuration management is for deployment automation rather than hosting.
Why the other options are wrong
- A. SAN provides networked storage but does not address how to host and maintain the legacy application itself.
- B. FaaS (Function as a Service) is designed for serverless computing and modern architectures, not legacy application hosting.
- D. Configuration management platforms manage deployment and updates but are not the primary hosting solution.
Question 86

Show answer and explanation
Correct answer: A. 3G/4G/5G/LTE settings
When a smartphone has no internet in a specific location but the device itself is functional, the first check should be whether cellular data (3G/4G/5G/LTE) is enabled and configured. A SIM connection issue would typically prevent connectivity everywhere, hotspot capability is for sharing, and GPS is unrelated to internet access.
Why the other options are wrong
- B. A faulty SIM connection would prevent connectivity in all locations, not just the parking lot.
- C. Hotspot capability is for sharing internet with other devices, not for the phone's own connectivity.
- D. GPS configuration does not affect cellular or mobile data connectivity.
Question 87
A user's computer can connect to internal network resources but cannot access websites on the internet. Other users on the same network do not have this issue. Which of the following should a technician do first to troubleshoot the issue?
Show answer and explanation
Correct answer: A. Verify the computer's DNS settings.
When a single computer cannot access external websites but can reach internal resources, and other users work fine, DNS settings should be checked first. The computer likely has incorrect DNS server settings preventing it from resolving internet domain names, while internal name resolution or IP routing still works for local resources.
Why the other options are wrong
- B. Replacing the network cable is unnecessary; the computer already demonstrates network connectivity to internal resources.
- C. Restarting the DHCP server would affect all users on the network, but the problem is isolated to one computer.
- D. Adjusting router firewall rules would typically affect multiple users; this issue is specific to one machine's configuration.
Question 88
A technician needs to deploy a router at a home office to provide internet access. The WAN port is required to connect to a static, public IP address assigned by the ISP. Which of the following should the ISP assign?
Show answer and explanation
Correct answer: C. 192.30.0.1
192.30.0.1 is the only option that represents a public IP address suitable for WAN port assignment. The ranges 10.x.x.x, 172.16.x.x through 172.31.x.x, and 192.168.x.x are all private IP address ranges reserved for internal use. A static public IP address from the ISP must come from the public IP space, making 192.30.0.1 the correct choice.
Why the other options are wrong
- A. 10.1.1.1 is in the private IP range (10.0.0.0/8) and cannot be assigned by an ISP as a public address.
- B. 172.16.0.1 is in the private IP range (172.16.0.0/12) and cannot be used for public WAN connections.
- D. 192.168.10.1 is in the private IP range (192.168.0.0/16) reserved for local networks.
Question 89
A technician installs an upgraded wireless access point. The technician then notices the activity light comes on briefly and turns off. The access point continues to exhibit this behavior repeatedly and does not come online. Which of the following is the most likely cause of this issue?
Show answer and explanation
Correct answer: B. Port flapping
Port flapping occurs when a port rapidly cycles between up and down states, causing the activity light to blink on and off repeatedly. This pattern of the activity light coming on briefly and turning off repeatedly, combined with the access point not coming online, is characteristic of port flapping. This often results from hardware issues, loose connections, or incompatibilities with the connected switch port.
Why the other options are wrong
- A. High latency would not cause the activity light to cycle on and off; the device would still come online.
- C. External interference might cause connectivity issues but would not produce the specific symptom of repeated activity light cycling.
- D. Channel conflict would affect wireless performance after the device comes online, not prevent it from coming online with cycling activity lights.
Question 90
A company needs to develop a disaster recovery solution based on virtual machines. Which of the following service models is the most suitable?
Show answer and explanation
Correct answer: A. Infrastructure as a service
Infrastructure as a Service (IaaS) is the most suitable model for a disaster recovery solution based on virtual machines because it provides on-demand access to computing resources, storage, and networking infrastructure. Organizations can provision virtual machines, replicate data, and maintain failover capabilities without owning physical infrastructure. IaaS gives the control and flexibility needed for DR planning.
Why the other options are wrong
- B. Security as a Service focuses on security controls and threat protection, not infrastructure provisioning for DR.
- C. Platform as a Service provides development frameworks and middleware, not the infrastructure-level control needed for VM-based disaster recovery.
- D. Software as a Service delivers applications to end-users, not the underlying infrastructure required for disaster recovery solutions.
Question 91
A user is having issues displaying the contents of their laptop screen on a projector. The laptop is connected using an HDMI cable, but the screen displays a message indicating there is no signal. Which of the following should the technician do first to diagnose the issue?
Show answer and explanation
Correct answer: A. Check the projector input sources.
When a projector shows 'no signal' despite proper cable connection, the first diagnostic step is to verify that the projector is set to the correct input source. Projectors often have multiple input options (HDMI 1, HDMI 2, VGA, etc.), and if the wrong input is selected, the projector will not display the signal even though the connection is valid. This is the quickest and most common cause of this symptom.
Why the other options are wrong
- B. Replacing the cable is premature before confirming the input source is correct and the cable is actually defective.
- C. Changing resolution may help after signal is established, but does not address the 'no signal' issue.
- D. Checking port damage is a later step; input source selection should be verified first as it is the most common cause.
Question 92

The user frequently walks between office rooms during the calls, leaving the laptop in place. The office wireless network uses fiber for internet access and consists of two wireless APs that are connected. Which of the following is most likely causing the connectivity issue?
Show answer and explanation
Correct answer: B. The user is moving in and out of range.
The user is experiencing intermittent Bluetooth audio issues while walking between office rooms while leaving the laptop stationary. Bluetooth has a typical range of 10-100 meters depending on obstacles and environmental conditions. As the user walks away from the laptop, the Bluetooth connection degrades when moving out of effective range, causing the sound to cut out intermittently. This is a classic range-related connectivity issue.
Why the other options are wrong
- A. The number of wireless APs is irrelevant to Bluetooth connectivity, which operates on a separate 2.4GHz frequency independent of Wi-Fi infrastructure.
- C. Mesh mode on APs would improve Wi-Fi coverage but does not affect Bluetooth headset connectivity, which is independent of wireless network configuration.
- D. Fiber internet speed is irrelevant to Bluetooth audio connectivity; the issue occurs with the Bluetooth link between headset and laptop, not the internet connection.
Question 93
Which of the following provides electricity to devices through network cables?
Show answer and explanation
Correct answer: B. PoE switch
A PoE (Power over Ethernet) switch provides electricity to devices through network cables. PoE switches inject DC power onto standard Ethernet cables, allowing connected devices such as IP cameras, wireless access points, and VoIP phones to receive both data and power from a single cable connection, eliminating the need for separate power supplies.
Why the other options are wrong
- A. An edge router routes network traffic but does not provide power delivery through network cables.
- C. An access point provides wireless connectivity but does not inherently deliver power through network cables unless it is a PoE-powered device itself.
- D. A patch panel is a passive connectivity device for organizing and terminating network cables; it does not provide electrical power.
Question 94
Which of the following is used to register inputs on a touch-screen monitor?
Show answer and explanation

Why the other options are wrong
- A. An inverter provides power to a backlight in older LCD displays but does not register touch input.
- C. OLED is a display technology that produces the image itself but does not register touch input.
- D. LCD is a display technology for rendering images but does not handle touch input registration.
Question 95
A technician is troubleshooting a connectivity issue on a network computer. The technician runs ipconfig in a command prompt and receives the following IP address: 169.254.0.6. Which of the following is most likely the type of IP address being assigned?
Show answer and explanation
Correct answer: C. Self assignment
An IP address in the range 169.254.0.0/16 is an Automatic Private IP Address (APIPA), which is self-assigned by the computer when it cannot reach a DHCP server. This occurs when there is no DHCP server available or the computer cannot communicate with one. DHCP reservations and dynamic assignments would be assigned by a DHCP server, and static assignments are manually configured by an administrator.
Why the other options are wrong
- A. DHCP reservations are assigned by a DHCP server and fall within the configured DHCP pool, not in the APIPA range.
- B. Dynamic assignments from a DHCP server would fall within the configured DHCP scope, not the 169.254.x.x APIPA range.
- D. Static assignments are manually configured and would not be in the automatic 169.254.x.x range.
Question 96
Which of the following ports should a technician disable to increase the security of remote connectivity?
Show answer and explanation
Correct answer: B. 23
Port 23 is Telnet, an unencrypted remote access protocol that transmits credentials in plaintext. It is a major security vulnerability and should be disabled in favor of SSH (port 22), which provides encrypted remote connectivity. Disabling Telnet is a fundamental security hardening practice for any system requiring remote access.
Why the other options are wrong
- A. Port 22 is SSH, the secure alternative to Telnet and should remain enabled for secure remote access.
- C. Port 25 is SMTP (email) and is not a remote connectivity port.
- D. Port 53 is DNS and is essential for name resolution across the network.
Question 97
A technician is setting up a workstation. Which of the following settings should the technician configure to ensure that users can connect to the network? (Choose three.)
Show answer and explanation
Correct answer: B, C, D. Gateway; IP address; Subnet mask
To connect a workstation to a network, three fundamental settings must be configured: the IP address (the device's network identifier), the subnet mask (which determines the local network range), and the gateway (which provides the route to networks outside the local subnet). These three components form the minimum required static network configuration for connectivity.
Why the other options are wrong
- A. APIPA is an automatic fallback mechanism, not a required configuration setting for connecting to a network.
- E. Static routes are advanced routing configurations needed only for specific network topologies, not for basic workstation connectivity.
- F. UPnP settings are optional features for device discovery and are not required for basic network connectivity.
- G. NAT rules are firewall/router configurations, not workstation settings needed for network connection.
- H. MAC filters are security controls on network devices, not settings required on the workstation itself for connectivity.
Question 98
A technician receives a notification after a network outage that indicates the printer is not reachable. Which of the following printer settings should the technician implement to prevent this issue in the future?
Show answer and explanation
Correct answer: B. Static IP
Assigning a static IP address to the printer ensures it maintains the same IP address after network outages or restarts. This allows the notification system and other network management tools to reliably locate the printer, preventing the 'not reachable' alerts that occur when DHCP reassigns a different IP.
Why the other options are wrong
- A. A gateway is a network device for routing between networks and does not address printer reachability after outages.
- C. APIPA (Automatic Private IP Addressing) is a fallback mechanism that assigns a link-local IP when DHCP fails, but it does not provide reliable, consistent addressing for network monitoring.
- D. DHCP assigns IP addresses dynamically, which means the printer's IP could change after a network outage, causing reachability issues.
Question 99
A customer is able to print most documents with their USB inkjet printer, but the system is unresponsive when printing a certain report from a custom application. Nothing will print until the computer is restarted and the printer is power cycled. A technician remotes into the PC and confirms that the spooler stops working when this report is sent. After clearing the spooler and reinstalling the drivers from the manufacturer's website, the issue persists. No other sites using the application report similar issues. Which of the following is most likely causing the issue?
Show answer and explanation
Correct answer: B. The application has a bug that the developer needs to address.
This is a classic case of an application-specific bug. The technician has already ruled out driver issues (reinstalled), spooler corruption (cleared), and hardware problems (other documents print fine). Since no other sites report this issue, it's specific to this custom application. The application likely generates a malformed print job that crashes the spooler, requiring the application developer to fix the print output generation code.
Why the other options are wrong
- A. Manufacturers don't curate print content to preserve ink; this would violate consumer expectations and is not a technical mechanism.
- C. PostScript vs. PCL language selection wouldn't cause the spooler to stop entirely and require a restart; it would cause formatting issues.
- D. Personal preference settings don't make documents unavailable; this is not a real technical phenomenon affecting print functionality.
Question 100
A computer displays an error message indicating there is insufficient storage when installing applications. The user reports slow application load times. Which of the following replacement components would best resolve this issue?
Show answer and explanation
Correct answer: A. SSD
The symptoms indicate both storage capacity issues (insufficient storage error) and performance problems (slow load times). An SSD (Solid State Drive) addresses both concerns: it provides fast read/write speeds to eliminate slow application load times and offers adequate storage capacity at reasonable cost. An HDD would only marginally improve speed, USB is external and temporary, and RAM would not resolve storage capacity issues.
Why the other options are wrong
- B. USB storage is external, temporary, and not suitable for installing applications or resolving the underlying storage problem.
- C. While an HDD provides capacity, it does not significantly improve the slow load times compared to an SSD.
- D. RAM improves system responsiveness and multitasking but does not resolve storage capacity or provide persistent application load speed improvements.
Question 101
Which of the following network technologies is used for the operation of physical access control systems?

Show answer and explanation
Correct answer: C. Type 2 hypervisor
A Type 2 hypervisor (hosted hypervisor) runs on top of an existing operating system and allows the customer to consolidate multiple bare-metal servers onto virtualized machines while maintaining control over the hardware in their own data center. This addresses both the privacy concern (data stays on-premises) and cost concerns (reducing physical hardware). IaaS would require external hosting, containers don't fully address OS compatibility for Windows/Unix/Linux mixes, and VDI is for desktop virtualization, not server consolidation.
Why the other options are wrong
- A. IaaS would host infrastructure externally, raising data privacy concerns for a cost-conscious customer.
- B. Containers require containerized applications and don't effectively handle disparate OS requirements like Windows, Linux, and Unix.
- D. VDI (Virtual Desktop Infrastructure) is designed for desktop virtualization, not consolidating multiple bare-metal servers.
Question 107
A major retailer is moving its online shopping website to the cloud and wants to expand its server resources as needed during busier shopping days. Which of the following should the retailer consider?
Show answer and explanation
Correct answer: B. Elasticity
Elasticity is the cloud characteristic that allows resources to automatically scale up or down based on demand. The retailer's need to expand server resources during busier shopping days and presumably contract them during slower periods is a direct definition of elasticity, the ability to dynamically provision and deprovision resources to match current workload requirements.
Why the other options are wrong
- A. Location refers to data center geographic placement and is not related to dynamic resource expansion needs.
- C. Availability refers to service uptime and reliability, not the ability to scale resources based on demand.
- D. Multitenancy refers to multiple customers sharing infrastructure, which is not the primary concern for scaling resources based on shopping traffic patterns.
Question 108
A technician is setting up a new SOHO wireless router. According to security best practices, which of the following should the technician do first?
Show answer and explanation
Correct answer: C. Change the default password.
Changing the default password should be done first as it immediately secures access to the router's administration interface, preventing unauthorized configuration changes. Encryption, static IP assignment, and factory reset are important but secondary to establishing secure admin access first.
Why the other options are wrong
- A. While encryption is essential, it cannot be properly configured if the router is still accessible with default credentials.
- B. Assigning a static IP is a network configuration task that should follow security hardening.
- D. Resetting the router would undo any configuration already in place and is counterproductive during initial setup.
Question 109
Which of the following devices forwards traffic based on MAC addresses?
Show answer and explanation
Correct answer: A. Switch
A switch forwards traffic based on MAC addresses by examining the destination MAC address in frames and forwarding them to the appropriate port on the local network segment. Switches operate at Layer 2 (Data Link Layer) and use MAC address tables to make forwarding decisions, making them the primary device for MAC-based forwarding.
Why the other options are wrong
- B. Routers forward traffic based on IP addresses, not MAC addresses, and operate at Layer 3.
- C. Firewalls filter traffic based on rules and IP addresses/ports, not MAC addresses.
- D. Gateways serve as network access points and work at multiple layers but are not primarily MAC address-based forwarders.
Question 110
Which of the following best describes the purpose of a firewall?

Why the other options are wrong
- B. RAM upgrades are not typically possible in smartphones and would not cause swelling.
- C. Changing the case would be a workaround but does not address the underlying dangerous battery problem.
- D. Factory reset would not resolve a physical hardware failure like battery swelling.
Question 117
A user can connect their laptop to the internet in the main office. However, when the user places the laptop on top of a motor on the factory floor, there is no internet connectivity. Which of the following is the most likely cause of this issue?
Show answer and explanation
Correct answer: C. External interference
A motor on the factory floor generates significant electromagnetic interference that disrupts wireless signals. The laptop connects fine in the main office but loses connectivity when placed near the motor, which is classic RF interference behavior. This is the most likely cause of the connectivity loss in that specific location.
Why the other options are wrong
- A. Jitter affects packet timing variability, not complete loss of connectivity.
- B. Insufficient power levels would affect signal strength gradually, not cause complete dropout based on physical location.
- D. High latency causes delay but not complete loss of internet connectivity.
Question 118
A group of friends is gathering in a room to play video games. One of the friends has a game server. Which of the following network types should the group use so they can all connect to the same server and the internet?
Show answer and explanation
Correct answer: C. LAN
A LAN (Local Area Network) is the appropriate network type for a group of devices in a single physical location, such as a room. A LAN allows multiple computers to connect to the same server and share internet access within a limited geographic area, making it ideal for friends in a room playing video games together.
Why the other options are wrong
- A. A SAN (Storage Area Network) is specialized for storage device connectivity, not general gaming or internet access.
- B. A MAN (Metropolitan Area Network) covers a larger geographic area than a room, such as a city or campus.
- D. A PAN (Personal Area Network) is extremely limited in range and connects only a few personal devices, not suitable for multiple users in a room.
Question 119
A company wants to enable access to corporate email on smartphones. Employees will choose from a list of supported devices but must install software that separates corporate and personal data. Which of the following should the company implement to achieve this goal?
Show answer and explanation
Correct answer: C. Mobile device management
Mobile Device Management (MDM) is specifically designed to enable corporate email access on employee-owned smartphones while maintaining data separation. MDM enforces the installation of required software, manages approved device lists, and creates isolated corporate data containers separate from personal data on the same device.
Why the other options are wrong
- A. Encryption alone does not separate corporate and personal data or manage device access policies.
- B. Network access control manages network connectivity but does not handle data separation or mobile device-specific requirements.
- D. Endpoint protection focuses on malware and threat prevention, not data segregation or device management.
Question 120
Which of the following DNS records would an administrator change to redirect email flow?
Show answer and explanation
Correct answer: A. MX
The MX (Mail Exchange) record is the DNS record type that specifies mail servers and prioritizes email delivery to the correct mail server. To redirect email flow to different mail servers or change email routing, an administrator must modify the MX records.
Why the other options are wrong
- B. TXT records store text information for various purposes like verification but do not control email flow routing.
- C. SPF records specify which servers are authorized to send email but do not redirect email flow themselves.
- D. CNAME records create aliases for domain names but are not used to redirect email flow to different mail servers.
Question 121
A technician is troubleshooting issues occurring on a user's mobile device. Applications and the OS have slow response times, even when performing simple tasks, such as writing an email. Additionally, new applications occasionally fail to launch. Which of the following should the technician do next?
Show answer and explanation
Correct answer: B. Close unnecessary programs.
Slow response times and applications failing to launch on a mobile device typically indicate insufficient available memory or processing resources. Closing unnecessary programs immediately frees up RAM and processing power, addressing the symptom directly. This is the logical first troubleshooting step before considering hardware replacement or factory reset, and it is non-destructive and quick to implement.
Why the other options are wrong
- A. Temperature is unlikely to be the cause of slow response times and application failures unless the device is overheating, which would typically show thermal warnings.
- C. Factory reset should only be done after other troubleshooting steps and will result in data loss; it is not the next logical step.
- D. Battery health affects runtime and may cause unexpected shutdowns, but it does not directly cause slow performance or application launch failures.
Question 122
Which of the following should be considered first when looking for replacement storage?
Show answer and explanation
Correct answer: A. Form factors
Form factors should be considered first when selecting replacement storage because they determine physical compatibility with the existing hardware. Before evaluating performance metrics like spindle speeds, RAID configurations, or technology types like NVMe, you must ensure the storage device can physically fit and connect to the system. Without proper form factor compatibility, no other specifications matter.
Why the other options are wrong
- B. RAID is a configuration consideration that applies after basic storage compatibility is established.
- C. Spindle speeds are a performance metric that only applies to mechanical drives and is secondary to form factor compatibility.
- D. NVMe is a specific technology type that is considered after determining whether the system supports the required form factor.
Question 123
Which of the following cloud types should be used when minimizing cost is the priority?
Show answer and explanation
Correct answer: B. Shared
Shared cloud services provide the lowest cost option because infrastructure, resources, and maintenance expenses are distributed across multiple customers. By sharing compute, storage, and networking resources among many organizations, each customer benefits from economies of scale and pays only for what they use, resulting in minimal per-organization costs.
Why the other options are wrong
- A. Dedicated cloud services require exclusive resource provisioning for a single customer, increasing costs significantly.
- C. Private cloud deployments require substantial upfront capital investment and ongoing maintenance costs, making them more expensive than shared models.
- D. Hybrid clouds combine private and public resources, which increases complexity and cost compared to purely shared models.
Question 124
A technician is setting up a locally hosted environment for internal developers who need concurrent access to a wide array of test OSs. Which of the following would best fulfill this requirement?
Show answer and explanation
Correct answer: A. Hypervisor
A hypervisor is the ideal solution for developers needing concurrent access to multiple test operating systems in a local environment. Hypervisors allow multiple virtual machines to run simultaneously on a single host, each with different operating systems, providing isolation and flexibility for testing without requiring physical hardware for each OS.
Why the other options are wrong
- B. SaaS platforms are cloud-based and not locally hosted, contrary to the requirement.
- C. A multiboot server can only run one OS at a time, not provide concurrent access to multiple test OSs.
- D. A sandbox provides an isolated environment for testing but is not designed for managing multiple concurrent OS instances for developers.
Question 125
A company wants to have fast read speeds for its locally stored data. Which of the following configurations has the lowest cost to fulfill this requirement?
Show answer and explanation
Correct answer: A. RAID 0
RAID 0 (striping) provides the fastest read speeds by distributing data across multiple drives and requires only two drives minimum, making it the lowest cost option for high read speed requirements. RAID 1, 5, and 10 all include redundancy overhead that increases cost without improving read speed performance.
Why the other options are wrong
- B. RAID 1 (mirroring) adds cost through redundancy without improving read speeds over RAID 0.
- C. RAID 5 includes parity calculations and requires at least three drives, increasing cost compared to RAID 0.
- D. RAID 10 combines mirroring and striping, requiring four drives minimum and significantly higher cost than RAID 0.
Question 126
Which of the following storage options would a technician most likely recommend to have large amounts of affordable capacity without concern for read times on a desktop computer?
Show answer and explanation
Correct answer: C. 2TB SATA 3.5 5,400rpm HDD
A 2TB SATA 3.5" 5,400rpm HDD offers large affordable capacity at a low cost per gigabyte, making it ideal for users prioritizing storage quantity over read speed. The question explicitly states 'without concern for read times,' so the slower rotational speed is acceptable. The NVMe SSD is much more expensive per GB, the RAID 1 configuration halves usable capacity, and the 15,000rpm SAS drive is enterprise-grade and extremely expensive.
Why the other options are wrong
- A. The 750GB NVMe M.2 SSD is expensive per gigabyte and provides minimal capacity compared to the alternatives.
- B. RAID 1 mirroring reduces usable capacity to 1TB total and is more costly, defeating the 'affordable capacity' requirement.
- D. The 4TB SAS 15,000rpm drive is enterprise-grade, extremely expensive per GB, and overkill for a desktop computer's performance needs.
Question 127
A customer recently lost data due to several unexpected shutdowns. Data integrity is important to the customer. Which of the following features should the technician choose to prevent data loss?
Show answer and explanation
Correct answer: B. Uninterruptible power supply
An Uninterruptible Power Supply (UPS) provides backup battery power during unexpected shutdowns and power failures, allowing systems to continue operating and properly shut down without data loss. This is essential for data integrity when facing unexpected power events.
Why the other options are wrong
- A. A redundant power supply provides failover within the device but does not protect against complete power loss or shutdowns.
- C. A modular power supply is a design feature allowing component replacement but offers no protection against power failures.
- D. A high-efficiency power supply reduces energy waste but does not prevent data loss during unexpected shutdowns.
Question 128
An IT specialist sets up a wireless router in a SOHO environment. Afterward, several devices cannot access the internet and are assigned IP addresses starting with 169.254. Which of the following is the best action to resolve this issue?
Show answer and explanation
Correct answer: A. Reboot the wireless router.
Devices assigned IP addresses starting with 169.254 are using APIPA (Automatic Private IP Addressing), which occurs when DHCP fails to assign addresses. Rebooting the wireless router will restart the DHCP service, allowing it to properly detect and configure connected devices with valid IP addresses from the DHCP pool. This is the quickest and most direct troubleshooting step for DHCP failures in a SOHO environment.
Why the other options are wrong
- B. Shortening the lease time does not address the root cause of DHCP failure; devices still need DHCP to respond initially.
- C. Using static IP addresses bypasses DHCP but is impractical in a SOHO environment with multiple dynamic devices and does not fix the underlying router issue.
- D. Increasing the DHCP pool size is irrelevant if the DHCP service itself is not responding; the pool size is not the problem.
