Implementing Cisco IP Telephony and Video Part 2 (CIPTV2, legacy) — Question 2

An engineer must enable video desktop sharing between a Cisco Unified Communications Manager registered video endpoint and a Cisco VCS registered video endpoint. Which protocol must be enabled in SIP profile for VCS SIP trunk on Cisco Unified Communications Manager?

Answer options

• A. RDP
• B. H.264
• C. H.224
• D. H.263
• E. BFCP

Correct answer: D

Explanation

The correct answer is D, H.263, as it is specifically designed for video compression in environments where bandwidth is limited, which is crucial for video desktop sharing. Options A (RDP) and E (BFCP) are not video codecs, while B (H.264) and C (H.224) are not the preferred choice for this particular use case.
