Implementing Cisco IP Telephony and Video Part 2 (CIPTV2, legacy) — Question 21

For which two reasons should you mark AF41 as the audio and video channels of a video call? (Choose two.)

Answer options

• A. to allow high-definition quality calls over low-speed links
• B. to give video calls a higher priority than AF41 in the QoS policy
• C. to provide separate classes for audio-only calls and video calls
• D. to prioritize video over other high-priority traffic classes
• E. to preserve lip synchronization between the audio and video channels

Correct answer: D, E

Explanation

The correct answers, D and E, are correct because marking AF41 prioritizes video traffic, ensuring it is transmitted effectively over other high-priority traffic, and helps maintain synchronization between audio and video, which is crucial for a cohesive call experience. Options A, B, and C do not accurately reflect the specific reasons for using AF41 in this context.
