Which statement is true about shaping?

A.
Shaping supports queuing of excess traffic.

B.
Shaping can be applied both input and output on interfaces.

C.
Shaping does not introduce delay in voice packet handling in the event of congestion.

D.
Shaping makes instantaneous packet drop decisions.

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. In contrast, traffic policing propagates bursts. When the traffic rate reaches the configured
maximum rate, excess traffic is dropped (or remarked). The result is an output rate that appears
as a saw-tooth with crests and troughs.
