SNCF — Securing Networks with Firepower — Question 96

A network security engineer must replace a faulty Cisco FTD device in a high availability pair. Which action must be taken while replacing the faulty unit?

Answer options

• A. Ensure that the faulty Cisco FTD device remains registered to the Cisco FMC
• B. Shut down the active Cisco FTD device before powering up the replacement unit
• C. Shut down the Cisco FMC before powering up the replacement unit
• D. Unregister the faulty Cisco FTD device from the Cisco FMC

Correct answer: D

Explanation

The correct action is to unregister the faulty Cisco FTD device from the Cisco FMC to ensure that the management system is aware of the change and can manage the new device properly. Keeping the faulty device registered (Option A) would cause conflicts, while shutting down the active unit (Option B) and the FMC (Option C) are unnecessary and could lead to service disruptions.
