Cisco Video Infrastructure Implementation — Question 41

Which protocol is used to communicate codec capabilities and Real-Time Transport Protocol ports?

Answer options

• A. H.460
• B. Session Description Protocol
• C. Real-Time Transport Control Protocol
• D. Assent

Correct answer: C

Explanation

The correct answer is C, as the Real-Time Transport Control Protocol (RTCP) is specifically designed to monitor transmission statistics and quality of service for Real-Time Transport Protocol (RTP) streams, including codec capabilities. Options A and D are unrelated to RTP, while B, the Session Description Protocol, is more focused on describing multimedia communication sessions rather than controlling RTP streams.
