210-065 Question #255: Real Exam Question with Answer & Explanation

The correct answer is A: URI. Registering a SIP endpoint to Cisco VCS requires only the SIP URI to identify the endpoint and the proxy address to direct registration traffic to the VCS server.

Question

On a video endpoint running TC software, which two SIP settings are the minimum needed to register the endpoint to a Cisco VCS? (Choose two.)

Options

AURI
Bloginname
Cpassword
DE.164 address
Egatekeeper
Fproxy address
Gdomain

Explanation

Registering a SIP endpoint to Cisco VCS requires only the SIP URI to identify the endpoint and the proxy address to direct registration traffic to the VCS server.

Common mistakes.

B. A loginname is not a minimum SIP registration parameter on TC software; authentication credentials may be optional depending on VCS policy.
C. A password is only required if the VCS enforces digest authentication; it is not a minimum requirement for basic SIP registration.
D. An E.164 address is an H.323 concept used for PSTN-style dialing and is not required for SIP registration to a VCS.
E. Gatekeeper is an H.323 registration concept, not a SIP setting, and has no role in SIP endpoint registration.
G. The domain can be derived from the SIP URI itself and does not need to be configured as a separate minimum setting for VCS registration.
