What are the three steps involved in implementing a QoS policy using MQC? (Choose three)

A.
Define a policy map.

B.
Define a traffic class.

C.
Set the match parameters for a policy map.

D.
Define a route map to set the QoS markings.

E.
Assign a service policy to an interface.

Explanation:

The simplicity of configuration is made possible through the use of a common configuration structure for all QoS components within the MQC. That is, the basic configuration steps for configuring all QoS mechanisms is the same, with only small variations in the configuration that are specific to the actual mechanism. You can configure all the mechanisms through a three-step process:
Step 1. Class map configuration
Step 2. Policy map configuration
Step 3. Service policy application
