Show Suggested Answer

Suggested Answer: C 🗳️
In the output you can see a * next to the ip address that is the primary NTP server.
Also the 377 that means everything was received and processed. Negotiation done. https://www.cisco.com/c/en/us/support/docs/ios-nx-os-software/ios-software-releases-110/15171-ntpassoc
377 = 1 1 1 1 1 1 1 1 Time 0: Last eight responses from server were received
376 = 1 1 1 1 1 1 1 0 Time 1: Last NTP response was NOT received (lost in network)
Values below this 376 is that Last NTP response was received
A pound sign (#) displayed next to a configured peer in the show ntp associations command output indicates that the router isn't syncing with the peer but NTP request and response packets are NOT exchanged.

B. Wrong answer and wrong citation. "A pound sign (#) displayed next to a configured peer in the show ntp associations command output indicates that the router isn't syncing with the peer even though NTP request and response packets are being exchanged."
