How does QoS traffic shaping alleviate network congestion?
A. It drops packets when traffic exceeds a certain bitrate.
B. It buffers and queue packets above the committed rate.
C. It fragments large packets and queues them for delivery.
D. It drops packets randomly from lower priority queues.
Answer:B

A. It drops packets when traffic exceeds a certain bitrate. B. It buffers and queue packets above the committed rate. C. It fragments large packets and queues them for delivery. D. It drops packets randomly from lower priority queues.
Explanation: Traffic shaping retains excess packets in a queue and then schedules the excess for later transmission over increments of time. The result of traffic shaping is a smoothed packet output rate.
