Implementing and Operating Cisco Security Core Technologies (SCOR) — Question 392

An administrator is configuring NTP on Cisco ASA via ASDM and needs to ensure that rogue NTP servers cannot insert themselves as the authoritative time source. Which two steps must be taken to accomplish this task? (Choose two.)

Answer options

• A. Choose the interface for syncing to the NTP server.
• B. Specify the NTP version
• C. Set the NTP DNS hostname
• D. Set the authentication key.
• E. Configure the NTP stratum

Correct answer: A, D

Explanation

Choosing the correct interface for NTP synchronization ensures that the ASA communicates with a trusted server, while setting the authentication key secures the communication by verifying the identity of the NTP server. The other options do not directly prevent rogue servers from being recognized as authoritative, making them less effective for this purpose.
