Traffic with the IPP value af21 should be assigned to the expedited forwarding queue; however, this
traffic is not being assigned to that queue. What is causing this behavior?

A.
The af21 traffic is assigned to the assured forwarding queue because of the BA classifier.

B.
The af21 traffic is assigned to the assured forwarding queue because of the MF classifier.

C.
The af21 traffic is assigned to the best effort queue because of the MF classifier.

D.
The af21 traffic is assigned to the best effort queue because of the BA classifier.
