SNCF — Securing Networks with Firepower — Question 126

A network administrator is implementing an active/passive high availability Cisco FTD pair. When adding the high availability pair, the administrator cannot select the secondary peer. What is the cause?

Answer options

• A. The second Cisco FTD is not the same model as the primary Cisco FTD.
• B. An high availability license must be added to the Cisco FMC before adding the high availability pair.
• C. The failover link must be defined on each Cisco FTD before adding the high availability pair.
• D. Both Cisco FTD devices are not at the same software version.

Correct answer: A

Explanation

The correct answer is A because Cisco FTD devices must be of the same model to establish a high availability pair. Options B, C, and D are incorrect as they do not directly prevent the selection of the secondary peer; a license, failover link configuration, or software version mismatch would not affect the model compatibility required for pairing.
