Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 567

Which NTP mode must be activated when using a Cisco router as an NTP authoritative server?

Answer options

• A. primary
• B. peer
• C. broadcast client
• D. server

Correct answer: D

Explanation

The correct answer is D, as a Cisco router must be set to 'server' mode to act as an authoritative NTP server, allowing it to provide time synchronization to clients. The other options do not enable the router to serve time; for instance, 'primary' and 'peer' are not valid NTP modes, while 'broadcast client' is meant for receiving time broadcasts rather than serving them.
