Implementing Cisco Collaboration Devices (CICD, legacy) — Question 101

The Cisco Unified IP Phone 9971 supports which protocol accessing the CLI to gather information and use debug commands?

Answer options

• A. SSHv2
• B. SSHv1
• C. CDP
• D. Telnet

Correct answer: D

Explanation

The correct answer is D, Telnet, as it is the protocol that allows remote access to the CLI of the Cisco Unified IP Phone 9971. SSHv1 and SSHv2 are secure protocols but are not supported for this phone, and CDP is used for network discovery rather than CLI access.
