You are working with a client to deploy QoS on their Frame Relay WAN. They would like to be able to allow packets to cross the Frame Relay WAN but have them marked as discard eligible if they exceed the QoS policy.How would you accomplish this task?（）A. Configure a class map that sets the DE bit so that the policy map can correctly apply a violate-action if the policy is exceeded.B. Configure a service policy that sets the DE bit and apply it to the serial interface connected to the Frame Relay WAN.C. Configure a policy map that has a burst-max action of setting the DE bit if the policy is exceeded.D. Configure a policy map that has a violate-action to change the DE bit from 0 to 1.

Customer X has a hub-and-spoke Frame Relay network， with a central office and two branch offices （RemoteA and RemoteB）. Each location has only one physical link to the Frame Relay cloud and RemoteB has a router that is not a Cisco router. Since the installation， there is no connectivity between RemoteB and the central office. What is a possible solution to this issue？ （）A、 Because Frame Relay IETF encapsulation is only configurable at interface level， you must use IETF encapsulation on all routers.B、 This is not a possible scenario. A dedicated Frame Relay link to RemoteB is mandatory at the central office.C、 The router at RemoteB must be replaced by a Cisco router.D、 Use Frame Relay IETF encapsulation on a per-VC basis on the central office router.E、 There is a problem in the Frame Relay cloud， because Cisco routers are compatible with IETF Frame Relay.
