350-801 Question #374: Real Exam Question with Answer & Explanation
The correct answer is B: Add an additional NTP server to the Cisco UCM publisher node.. If a Cisco UCM subscriber node is unsynchronized, despite external connectivity, the issue often stems from the publisher not having a reliable NTP source; therefore, configuring additional NTP servers on the publisher node can resolve this.
Question
Refer to the exhibit. An engineer is troubleshooting an NTP synchronization issue that returns a message of 'unsynchronized' when the utils ntp status command is run on the Cisco UCM subscriber node. The connectivity between the subscriber and the NTP server was verified as working, and the NTP server is running. Which action resolves the issue?
Options
- AAdd an additional NTP server on the Cisco UCM subscriber node.
- BAdd an additional NTP server to the Cisco UCM publisher node.
- CEnsure that the Cisco UCM subscriber node is running.
- DEnsure that the Cisco UCM publisher node is up and running.
Explanation
If a Cisco UCM subscriber node is unsynchronized, despite external connectivity, the issue often stems from the publisher not having a reliable NTP source; therefore, configuring additional NTP servers on the publisher node can resolve this.
Common mistakes.
- A. Cisco UCM subscriber nodes do not directly synchronize with external NTP servers; they rely on the publisher as their primary time source.
- C. The question implies the subscriber node is running, as the 'utils ntp status' command was executed on it; if it were not running, the command couldn't be executed.
- D. The question implies the publisher is running, as it's the expected time source; if it were down, the subscriber would likely report different errors or simply not synchronize.
