    we missed the third one that is Frame Relay

    Explanation: On each WAN connection, data is encapsulated into frames before it
    crosses the WAN link. The following are typical WAN protocols:
    1. High-level Data Link Control (HDLC): The Cisco default encapsulation type on
    point-to-point connections, dedicated links, and circuit-switches connections.
    2. PPP: Provides router-to-router and host-to-network connections over synchronous and
    asynchronous circuits. PPP was designed to work with several network layer protocols,
    including IP.
    3. Frame-relay: A successor to X.25. This protocol is an industry-standard, switches
    data-link layer protocol that handles multiple virtual circuits

    It is MPLS also!!!!!!!! I shocked when I saw it excluded.. Most companies change their old Frame-Relay networks to MPLS in these days.
