Click the Exhibit button.
Traffic with the IP precedence value af21 ingresses the router and should be rewritten with the same
value as it egresses; however, this traffic is rewritten to a different value.
Referring to the exhibit, what is the source of this problem?
A. The BA classifier is assigning the traffic to the best-effort queue with a high loss priority.
B. The BA classifier is assigning the traffic to the best-effort queue with a low loss priority.
C. The BA classifier is assigning the traffic to the expedited forwarding queue with a high loss priority.
D. The BA classifier is assigning the traffic to the expedited forwarding queue with a low loss priority.
Correct Answer: D
