Implementing Cisco IP Telephony and Video Part 2 (CIPTV2, legacy) — Question 30

QoS should be configured on Cisco VCS because it processes the media and the call signaling. The endpoints that register to Cisco VCS (such as the Cisco
TelePresence System EX Series, C Series, and Cisco IP Video Phone E20) should be configured so that media uses which Layer 3 DSCP packet value?

Answer options

Correct answer: D

Explanation

The correct answer is D, CS3 (24), which is commonly used for voice traffic to ensure proper QoS. Option A (AF41) and option B (EF) are used for different priority levels, while option C (CS4) is typically reserved for video traffic, making them less suitable for the media traffic needs in this context.
