Designing Cisco Enterprise Networks (ENSLD) — Question 53

The customer solution requires QoS to support streaming multimedia over a WAN. An architect chooses to use Per-Hop Behavior. Which solution should the engineer use to classify and mark traffic traveling between branch sites?

Answer options

• A. CBWFQ with DSCP AF2
• B. LLQ with DSCP EF
• C. CBWFQ with DSCP AF3
• D. LLQ with DSCP AF4

Correct answer: C

Explanation

The correct answer is C, as CBWFQ with DSCP AF3 is suitable for multimedia traffic, ensuring it gets the necessary bandwidth and priority. Options A and B do not provide the same level of service required for streaming, while D uses an inappropriate DSCP marking for multimedia applications.
