Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 180

What are two reasons that AF41 is marked for 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 calls and video calls
• D. to preserve lip synchronization between the audio and video channels
• E. to prioritize video over other high-priority traffic classes

Correct answer: C, D

Explanation

The correct answers, C and D, highlight the need to have separate classifications for audio and video calls and to ensure that lip synchronization is achieved during video communications. Options A and B do not address the specific functions of AF41, while option E relates to traffic prioritization but does not pertain to the separation of audio and video channels.
