Users at the Charleville Company began experiencing high network delays when Internet connectivity was enabled for all users. After investigating the traffic flow, you determine that peerto-peer traffic from a music download site is consuming a large amount of bandwidth. Which QoS mechanism can you implement to improve the network response time?()A. Use CBWFQ to queue the peer-to-peer traffic into the default traffic class.B. Use class-based WRED to randomly drop the peer-to-peer traffic during network congestions.C. Use class-based policing to limit the peer-to-peer traffic rate.D. Use class-based shaping to delay any excessive peer-to-peer traffic. Answer: C
