A. ttach the class map to a policy map that designates the action to be taken on the classified traffic and then attach the policy map to an interface using a service policy
B. ttach the class map to a policy map that sets the minimum bandwidth allocated to the classified traffic and designates the action to be taken on the traffic
C. ttach the class map to a policy map within a VRF to segregate the high-priority traffic and then attach the policy map to an interface in another VRF
D. reate a route map to manipulate the routes that are entered into the routing table and then attach the route map to an interface using a service policy
