Which statement regarding the policing traffic conditions in IP QoS is valid?

Which statement regarding the policing traffic conditions in IP QoS is valid?

A.
Policing allows the network administrators to traffic engineer paths through the network for application flows.

B.
Policing techniques monitor network traffic loads to anticipate and avoid congestion.

C.
Policing is the ability to control bursts and conform traffic to ensure certain traffic types receive specified amounts of bandwidth.

D.
Policing reorders transmit queues to offer priority service to specific traffic flows.

E.
Policing utilizes buffers to delay excessive traffic when the flow is higher than expected.

Explanation:
Incorrect:
C. With shaping, traffic bursts are smoothed out producing a steadier flow of data E. Policing does not introduce any delay to traffic that conforms to traffic policies

The QoS tool used to monitor the rate, and discard the excess traffic, is called traffic policing, or just policing. Because the provider is monitoring traffic sent by the customer, traffic polices typically monitor ingress traffic, although they can monitor egress traffic as well.
