Cisco Implementing Cisco Collaboration Hybrid and Cloud Technologies (CLHCT) v2.0 Sample Questions (Q173-Q178):

NEW QUESTION # 173
Refer to the exhibit. A customer reports degraded video quality during Webex Meetings. An engineer examines the Webex Control Hub statistics and notices the uplink bandwidth from the customer's site fluctuates sharply. Which two actions must the engineer take to restore video performance? (Choose two.)

A. Reconfigure "class-default" to use policing instead of fair queue.
B. Disable QoS on the WAN interface to avoid bandwidth misallocation.
C. Verify that ingress traffic marking from endpoints matches the expected DSCP.
D. Increase the priority bandwidth allocated for the VIDEO class.

Answer: C,D

Explanation:
Webex video quality depends on sufficient prioritized WAN bandwidth and correct DSCP classification. The policy prioritizes traffic marked AF41, so the engineer should confirm that Webex endpoints are marking video traffic as expected and increase the VIDEO class priority allocation if the current 20% is insufficient during fluctuating uplink conditions.
