Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 147

When setting a new primary DNS server in the Cisco UCM CLI, what is required for the change to take effect?

Answer options

• A. restart of CallManager service
• B. restart of DirSync service
• C. restart of the network service
• D. restart of TFTP service

Correct answer: C

Explanation

To apply changes made to the primary DNS server in Cisco UCM, it is essential to restart the network service, as this service handles DNS resolution. Restarting the CallManager, DirSync, or TFTP services will not impact DNS settings, making option C the only correct choice.
