Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 385

An engineer deploys a new Cisco UCM server as a TFTP-only node to an existing Cisco UCM cluster. Where must the IP address of the TFTP server be configured to ensure that IP phones use the new TFTP server?

Answer options

• A. in the Option 066 field for DHCP
• B. in the Cisco UCM device pools
• C. in the Option 150 field for DHCP
• D. in the Cisco UCM device configuration

Correct answer: C

Explanation

The correct answer is C because the Option 150 field in DHCP is specifically used to provide the IP address of TFTP servers to IP phones. Option 066 can also provide TFTP server information but is less commonly used in modern configurations. The Cisco UCM device pools and device configuration do not directly impact how IP phones obtain their TFTP server address from DHCP.
