Designing Cisco Enterprise Networks (ENSLD) — Question 257

A customer is undergoing a WAN re-architecture and wants to design QoS policies for remote sites that have low bandwidth. What must be considered to have CBWFQ configured in the parent and child policies in an end-to-end QoS design?

Answer options

• A. Traffic policing is required in the child policy.
• B. CBWFQ is only supported in the child policy.
• C. CBWFQ is only supported in the parent policy.
• D. Traffic shaping is required in the parent policy.

Correct answer: D

Explanation

The correct answer is D because traffic shaping in the parent policy is essential for effective bandwidth management when implementing CBWFQ. Options A, B, and C are incorrect as they do not reflect the requirements for CBWFQ configuration in both policies.
