Refer to the exhibit. Which command is used to complete this configuration for QoS class-based marking?
The configuration shown is about QoS class-based marking, and the DSCP (Differentiated Services Code Point) value for Expedited Forwarding (EF) is used to mark traffic for low latency. The correct command to complete this configuration by setting the DSCP value to EF is 'set dscp ef.' Therefore, the appropriate option is 'set dscp ef.'
The name of the policy is "mark", so if wen need to mark (actually remark) the traffic, then A is the answer.
