Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 318

In a Dual Video Queue approach, what is the purpose of the CS4 class for Cisco video devices?

Answer options

• A. Desktop video traffic needs strict priority queuing marked with CS4 class
• B. Create a simpler provisioning with one CBWFQ for desktop and immersive video traffic
• C. Enforce a strict priority queueing for both desktop and immersive video traffic
• D. Immersive video traffic is marked with CS4 and placed in a CBWFQ separate from desktop video

Correct answer: D

Explanation

The correct answer is D because the CS4 class is specifically used to mark immersive video traffic and separate it into its own CBWFQ, ensuring it is treated differently from desktop video. Options A and C incorrectly imply that only desktop video or both types need strict priority queuing, while option B suggests a unified approach that does not align with the purpose of the CS4 class.
