Refer to the exhibit.

The input service policy shown in the exhibit matches traffic with DSCP value 1 and applies a QoS set action to rewrite that marking to DSCP 63. Therefore, packets entering interface Fa7/0/2 with DSCP 1 are remarked to DSCP 63, making option B correct. The second part of the configuration defines a class map matching DSCP 63 and a policy map using bandwidth percent 50. That behavior belongs to class-based queuing/scheduling, where DSCP63-marked traffic is placed into a class that receives a bandwidth allocation. In the given option set, option C best represents this queuing behavior. Option D is wrong because the service policy explicitly changes the DSCP value. Option E is not accurate because classification is not triggered by reaching 50 percent bandwidth; classification occurs by matching packet fields such as DSCP. Option A is less precise than C because the shown policy behavior is class-based queuing with a bandwidth allocation. The important ENCOR concept is the separation between marking on ingress and queuing/scheduling on egress.
