SNCF — Securing Networks with Firepower — Question 34

An engineer currently has a Cisco FTD device registered to the Cisco FMC and is assigned the address of 10.10.50.12. The organization is upgrading the addressing schemes and there is a requirement to convert the addresses to a format that provides an adequate amount of addresses on the network. What should the engineer do to ensure that the new addressing takes effect and can be used for the Cisco FTD to Cisco FMC connection?

Answer options

• A. Update the IP addresses from IPv4 to IPv6 without deleting from Cisco FMC.
• B. Format and reregister the device to Cisco FMC.
• C. Cisco FMC does not support devices that use IPv4 IP addresses.
• D. Delete and reregister the device to Cisco FMC.

Correct answer: D

Explanation

The correct answer is D because deleting and re-registering the device allows the new addressing scheme to take effect. Options A and C are incorrect as Cisco FMC does support IPv4 addresses, and simply updating to IPv6 without re-registration (Option B) would not properly apply the new settings.
