Cisco Video Infrastructure Implementation — Question 9

In an H.323 call that is not interworked, which three signaling protocols are routed through the Expressway? (Choose three.)

Answer options

• A. RTP
• B. H.245
• C. RAS
• D. RTCP
• E. Q.931
• F. H.254

Correct answer: C, E, F

Explanation

The correct answer includes RAS, Q.931, and H.254, as these are the signaling protocols specifically routed through the Expressway in a non-interworked H.323 call. RTP and RTCP are used for media transport rather than signaling, and H.245 is involved in control signaling but is not routed through the Expressway in this context.
