350-801 Question #283: Real Exam Question with Answer & Explanation

Question

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?

Options

• ARestart NTPD on the Cisco UCM server
• BStart the NTP service on the new NTP server
• CConfigure the "reach" value as "377" for the new NTP server
• DDelete and re-add the new NTP server via the Cisco UCM command-line interface

Explanation

When a new NTP server shows 'Not Accessible' in Cisco UCM OS Administration, a common resolution is to delete and re-add the server via the CLI to force a proper re-initialization and synchronization.

Common mistakes.

• A. Restarting NTPD on the Cisco UCM server might address issues with the CUCM's NTP daemon, but it is less effective than a full re-add via CLI for resolving a specific server's 'Not Accessible' status.
• B. The prompt implies the new NTP server is configured and running; if the NTP service was not started on the new server itself, the issue would be more general unreachability, not a specific CUCM 'Not Accessible' status after adding.
• C. The 'reach' value is a dynamically calculated metric by the NTP daemon to assess peer health and is not a manually configurable parameter; attempting to set it would not resolve the 'Not Accessible' status.
