Which QoS mechanism can you implement to improve the network response time?

A. Use class-based shaping to delay any excessive peer-to-peer traffic.

B. Use class-based policing to limit the peer-to-peer traffic rate.

C. Use class-based marking to mark the peer-to-peer traffic to DSCP 0

D. Use class-based WRED to randomly drop the peer-to-peer traffic during network congestions.

E. Use CBWFQ to queue the peer-to-peer traffic into the default traffic class.
