Which of the following is true?

A. Master is syncing and exchanging NTP packets successfully

B. Master is not syncing but exchanging NTP packets successfully

C. Master is not syncing and not exchanging NTP packets

D. All NTP packets are dropped








 

Suggested Answer: B

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 even though NTP request and response packets are being exchanged.
