Refer to the exhibit. Which WAN protocol is being used?

The correct answer is C. Frame Relay. The exhibit shows output characteristic of Frame Relay - specifically, it would display DLCIs (Data Link Connection Identifiers), LMI (Local Management Interface) type, and PVC (Permanent Virtual Circuit) status. Frame Relay is a packet-switched WAN technology that uses DLCIs to

Explanation

The exhibit shows output characteristic of Frame Relay - specifically, it would display DLCIs (Data Link Connection Identifiers), LMI (Local Management Interface) type, and PVC (Permanent Virtual Circuit) status. Frame Relay is a packet-switched WAN technology that uses DLCIs to identify virtual circuits between endpoints. The presence of these Frame Relay-specific identifiers in the exhibit distinguishes it from ATM (which uses VPI/VCI), HDLC (a simple serial encapsulation with no virtual circuit identifiers), or PPP (which also lacks virtual circuit addressing).
