Three of the 769 questions in this pack

Question 1

Which of the following steps of the troubleshooting methodology would most likely include checking through each level of the OSI model after the problem has been identified?

  1. Establish a theory.
  2. Implement the solution.
  3. Create a plan of action.
  4. Verify functionality.
Show answer and explanation

Correct answer: A. Establish a theory.

After identifying the problem, the next step in the CompTIA troubleshooting methodology is to establish a theory of probable cause, which often involves questioning the obvious and systematically examining each layer of the OSI model to isolate where in the network stack (physical, data link, network, transport, session, presentation, application) the fault may lie. This structured approach helps technicians narrow down potential causes before testing the theory, making it the step most closely associated with methodically reviewing OSI layers.

Why the other options are wrong

  • B. Implementing the solution occurs after the cause has been confirmed and a plan devised, not during initial cause analysis.
  • C. Creating a plan of action happens after the theory has been tested and confirmed, focused on how to resolve the issue rather than diagnosing it.
  • D. Verifying functionality is the final step to confirm the fix works and involves testing the whole system, not layer-by-layer diagnosis of cause.

Question 2

While troubleshooting a VoIP handset connection, a technician's laptop is able to successfully connect to network resources using the same port. The technician needs to identify the port on the switch. Which of the following should the technician use to determine the switch and port?

  1. LLDP
  2. IKE
  3. VLAN
  4. netstat
Show answer and explanation

Correct answer: A. LLDP

LLDP (Link Layer Discovery Protocol) allows devices to discover and identify neighboring network devices and the switch ports they are connected to. This is the standard protocol for determining switch identity and port information without requiring manual configuration or network access.

Why the other options are wrong

  • B. IKE (Internet Key Exchange) is related to VPN encryption, not device/port discovery.
  • C. VLAN configuration helps segment networks but doesn't identify which physical switch port a device connects to.
  • D. netstat displays network connections and statistics from the local device, not switch port information.

Question 3

A network administrator needs to set up a file server to allow user access. The organization uses DHCP to assign IP addresses. Which of the following is the best solution for the administrator to set up?

  1. A separate scope for the file server using a /32 subnet
  2. A reservation for the server based on the MAC address
  3. A static IP address within the DHCP IP range
  4. A SLAAC for the server
Show answer and explanation

Correct answer: B. A reservation for the server based on the MAC address

A DHCP reservation binds a specific MAC address to a fixed IP address, ensuring the file server always receives the same IP while remaining under DHCP management. This provides the reliability needed for a server that must be consistently addressable while maintaining DHCP infrastructure benefits.

Why the other options are wrong

  • A. A /32 subnet is a single host and creates unnecessary complexity; reservations are simpler.
  • C. Assigning a static IP within the DHCP range can cause conflicts if DHCP also assigns that address.
  • D. SLAAC (Stateless Address Auto-Configuration) is for IPv6 and doesn't provide the centralized control needed for server management.

    My base for every cert

    This dump is legit. I study for certs fairly regularly and I always get it as a base. Will not prep without it going forward.

  6. Tess Jones –

    Good value regardless

    Quick prep and passed. Cheap and effective. Passed and will keep using it. My company covers my cert costs so price isnt really a factor for me. But even so this is clearly good value. Real exam questions for a very cheap price.

What makes the Network+ hard

Over 40% of candidates fail their first attempt at the Network+, not because they do not know networking, but because the exam tests five demanding domains across 90 minutes and includes performance-based questions that require you to troubleshoot and configure, not just recognise correct answers.

The N10-009 is broader than most candidates expect: networking concepts, implementation, operations, security and troubleshooting are all tested, and the troubleshooting domain alone is worth 24% of the exam. Candidates who spend their study time on subnetting and OSI models and skip the operations and security domains walk out surprised. This pack has 769 practice questions for the N10-009, every MCQ and PBQ, so the question format is familiar before test day.

About the exam

The CompTIA Network+ is the vendor-neutral standard certification for networking fundamentals. It validates the ability to establish, maintain, troubleshoot and secure wired and wireless networks across enterprise environments, covering networking concepts, implementations, operations, security and troubleshooting. DoD 8140 approved and the recognised baseline credential for network administrator, NOC technician and network support specialist roles. Current version V9, series code N10-009, launched 20 June 2024. CompTIA A+ plus 9 to 12 months of hands-on networking experience is recommended.
