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.
