Designing Cisco Enterprise Networks (ENSLD) — Question 91

An engineer is designing a QoS policy that queues excess packets for later transmission. Which mechanism must be included in the design?

Answer options

• A. shaping
• B. WRED
• C. policing
• D. RED

Correct answer: A

Explanation

The correct answer is A, shaping, because it is specifically designed to buffer excess packets and manage bandwidth. Options B (WRED) and D (RED) are both methods of congestion avoidance through packet dropping, rather than queuing. Option C (policing) is used for traffic management by dropping excess packets, which does not involve queuing.
