Refer to the exhibit.
A collaboration engineer adds a redundant NTP server to an existing Cisco Collaboration solution. On the Cisco UCM OS Administration page, the new NTP server shows as “Not Accessible”. Which action resolves this issue?
A. Delete and re-add the new NTP server via the Cisco UCM command-line interface.
B. Start the NTP service on the new NTP server.
C. Configure the “reach” value as “377” for the new NTP server.
D. Restart NTPD on the Cisco UCM server.
According to the information shared by SD-Bob, CUCM automatically restarts NTP service when it add a new server, so if a fail is found NTP service has to be restarted manually, then correct answer should be D
It is more like B. Delete and re-add don’t think is a solution.
Not entirely sure if A is the correct answer but there is some verbiage that might indicate that step.
