There is a lot of traffic marked with IP precedence values af2l and af3l that ingresses the router.
The af3l traffic should be using the expedited forwarding queue, but the traffic is much lower than
expected and there are no drops seen on the egress interface.

Referring to the exhibit, what is causing the problem?

A.
The assured forwarding queue has a strict high priority and is starving the expedited forwarding
queue.

B.
The expedited forwarding queue has a low priority value; therefore the traffic is not serviced.

C.
The MF classifier is forwarding most of the af3l traffic to the best-effort queue.

D.
The MF classifier is does not match on af3l and therefore the traffic is being dropped.
