Question 1
What is a result of enabling Cisco FTD clustering?
Show answer and explanation
Correct answer: C. Site-to-site VPN functionality is limited to the master unit, and all VPN connections are dropped if the master unit fails.
In FTD clustering, site-to-site VPN is a centralized feature that runs only on the control (master) unit. VPN sessions are not distributed to data units and are not backed up, so if the master unit fails, all existing site-to-site VPN connections are dropped and must be rebuilt after a new master is elected.
Why the other options are wrong
- A. With dynamic routing, the routing process restarts and reconverges on the new master, so existing connections are not all maintained.
- B. Integrated Routing and Bridging is not supported when clustering is enabled, so it is not a result of enabling FTD clustering.
- D. Not all Firepower appliances support FTD clustering; only certain models and form factors are compatible with clustering.
Question 2
Which two conditions are necessary for high availability to function between two Cisco FTD devices? (Choose two.)
Show answer and explanation
Correct answer: A, E
A. The units must be the same version E. The units must be the same model. For high availability to function between two Cisco FTD devices, the units must be the same version to ensure compatibility of state synchronization protocols and feature parity. Additionally, the units must be the same model to guarantee identical hardware capabilities, processing power, and interface configurations necessary for seamless failover.
Why the other options are wrong
- B. Both devices can be in the same group within the FMC; they do not need to be in different groups, and domain requirements are not a primary HA constraint.
- C. If units are part of the same series, they must be the same model for HA, not different models.
- D. High availability is supported in both routed and transparent modes; it is not limited to firewall routed mode only.
Question 3
On the advanced tab under inline set properties, which allows interfaces to emulate a passive interface?
Show answer and explanation
Correct answer: B. TAP mode
TAP mode (Traffic Access Point mode) on the advanced tab under inline set properties allows interfaces to emulate a passive interface. In TAP mode, the device passively monitors traffic without actively blocking or forwarding it, making it behave like a passive tap on the network rather than an active inline appliance.
Why the other options are wrong
- A. Transparent inline mode processes traffic actively between inline pairs but does not specifically emulate a passive interface.
- C. Strict TCP enforcement is a security policy setting for TCP connection handling, not an interface mode for passive emulation.
- D. Propagate link state is a feature for maintaining link status awareness across inline pairs, not for emulating passive interfaces.
Question 4
What are the minimum requirements to deploy a managed device inline?
Show answer and explanation
Correct answer: A. inline interfaces, security zones, MTU, and mode
Cisco documents the minimum requirements for deploying a managed device inline as inline interfaces, security zones, MTU, and mode. You pair the interfaces into an inline set, assign each interface to a security zone so access control and intrusion policies can match the traffic, set the MTU, and select the inline mode of operation.
Why the other options are wrong
- B. A passive interface only receives copied traffic and cannot be used for an inline deployment.
- C. This list omits security zones, which are required so policies can reference the inline interfaces.
- D. Inline deployment requires paired inline interfaces, not a passive interface.
Question 5
What is the difference between inline and inline tap on Cisco Firepower?
Show answer and explanation
Correct answer: D. Inline mode can drop malicious traffic.
The key difference between inline and inline tap modes is that inline mode can drop malicious traffic by actively blocking connections, while inline tap mode operates passively and cannot drop traffic. Inline mode actively inspects and enforces security policies with the ability to block malicious packets, whereas inline tap mode only monitors and can alert but cannot enforce blocking.
Why the other options are wrong
- A. Inline tap mode receives a copy of traffic for monitoring but does not send copies to other devices; traffic flow is unidirectional to the appliance.
- B. Both inline and inline tap modes can perform full packet capture; packet capture capability is not a differentiator between these modes.
- C. Inline mode can perform SSL decryption if configured with appropriate certificates; SSL decryption is not limited in inline mode.
Question 6
With Cisco FTD software, which interface mode must be configured to passively receive traffic that passes through the appliance?
Show answer and explanation
Correct answer: D. inline tap
Inline tap mode keeps the interfaces in the data path so traffic still passes through the appliance, while a copy of each packet is sent to the inspection engine. The device can generate events but cannot drop or modify the traffic, so it passively receives traffic that passes through it.
Why the other options are wrong
- A. An inline set without tap mode actively inspects and can drop or modify traffic rather than receiving it passively.
- B. Passive mode inspects a copy of traffic from a SPAN or tap, so that traffic does not pass through the appliance.
- C. Routed mode actively routes traffic between interfaces rather than passively receiving or monitoring it.
Question 7
Which two deployment types support high availability? (Choose two.)
Show answer and explanation
Correct answer: A, B
A. transparent B. routed The two deployment types that support high availability in Cisco FTD are transparent and routed modes. Both of these deployment modes support active-standby HA configurations where a secondary device can take over if the primary device fails, maintaining continuous network connectivity and security services.
Why the other options are wrong
- C. Clustered deployments are a separate redundancy architecture from high availability and operate differently with multiple active units rather than active-standby HA pairs.
- D. Intra-chassis multi-instance deployments involve multiple logical instances on a single physical appliance and do not support traditional high availability between separate devices.
- E. Virtual appliances in public cloud environments have different HA mechanisms specific to cloud platforms and are not considered standard FTD HA deployment types.
Question 8
Which protocol establishes network redundancy in a switched Firepower device deployment?
Show answer and explanation
Correct answer: A. STP
Spanning Tree Protocol (STP) is the protocol that establishes network redundancy in a switched Firepower device deployment. STP prevents layer 2 loops in switched network topologies by blocking redundant paths and enabling failover when primary links fail, making it essential for maintaining network stability in switched environments with multiple connections.
Why the other options are wrong
- B. HSRP (Hot Standby Router Protocol) provides gateway redundancy for routed interfaces, not switched network redundancy.
- C. GLBP (Gateway Load Balancing Protocol) is used for load balancing between gateway redundancy pairs, not for switched infrastructure redundancy.
- D. VRRP (Virtual Router Redundancy Protocol) provides virtual router redundancy for routed gateways, not for switched layer 2 network redundancy.
Question 9
Which interface type allows packets to be dropped?
Show answer and explanation
Correct answer: B. inline
Inline interfaces operate in the data path where packets are actively inspected and can be dropped based on policy decisions. This is the fundamental characteristic of inline mode, traffic flows through the device and can be denied or allowed based on inspection results. Passive interfaces (TAP/SPAN) only monitor traffic without affecting the data path, and ERSPAN is a remote monitoring technology that doesn't drop packets.
Why the other options are wrong
- A. Passive interfaces only monitor traffic and cannot drop packets.
- C. ERSPAN is an encapsulated remote monitoring protocol that doesn't perform active packet dropping.
- D. TAP interfaces are passive monitoring points that cannot drop packets.
