How does an administrator change the DNS settings on Cisco UCM?

Answer options

• A. Find the DNS setting in the system parameter settings in the Network section

• C. Go to Network > IP > Cisco Serviceability and change the DNS settings
• D. Open an SSH session to each node in the Cisco UCM cluster and change the DNS setting using CLI

Correct answer: D

Explanation

The correct answer, D, involves directly accessing each node in the Cisco UCM cluster through SSH to change DNS settings using the command-line interface, which is necessary for comprehensive configuration. Options A, B, and C suggest GUI methods, which do not apply to changing DNS settings in this context, as they are typically set via CLI for more control.
