SNCF — Securing Networks with Firepower — Question 134

A network administrator has converted a Cisco FTD from using LDAP to LDAPS for VPN authentication. The Cisco FMC can connect to the LDAPS server, but the Cisco FTD is not connecting. Which configuration must be enabled on the Cisco FTD?

Answer options

• A. The LDAPS must be allowed through the access control policy.
• B. The RADIUS server must be defined.
• C. SSL must be set to a use TLSv1.2 or lower.
• D. DNS servers must be defined for name resolution.

Correct answer: D

Explanation

The correct answer is D because for the Cisco FTD to connect to the LDAPS server, it needs to resolve the server's hostname to an IP address, which requires DNS. The other options are not relevant to the FTD's ability to connect to the LDAPS server; they pertain to different configurations that do not address name resolution.
