A. It may exceed PIR of the queue.

B. It may be exceeded by the average servicing rate of the queue.

C. It varies depending on the traffic characteristics.

D. It is the rate at which packets are forwarded out of the queue.

Which of the following statements about behavior aggregate and multi-field classification in a Nokia 7750 SR is TRUE?
