Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 191

Which entity does Cisco UCM use DNS to resolve fully qualified domain names to an IP address?

Answer options

• A. application server name
• B. SIP trunk
• C. Cisco UCM Name
• D. primary TFTP server for option 150

Correct answer: B

Explanation

The correct answer is B, as SIP trunks require DNS resolution for establishing communication between different SIP endpoints. The other options, such as application server names, Cisco UCM names, and primary TFTP servers, do not directly involve DNS for resolving FQDNs to IP addresses in the same context as SIP trunks.
