Suggested Answer: AC 🗳️
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, switchesdata-link layer protocol that handles multiple virtual circuits http://en.wikipedia.org/wiki/Wide_area_network http://www.ciscopress.com/articles/article.asp?p=102157&seqNum=2

I think C and E because PPP is a protocol not a connectivity method. DSL and Ethernet are two valid WAN connectivity method.

A protocol can definitely be a method, why not? You have different protocols, so different methods of communicating. Ethernet is a LAN connectivity method, but you do have PPPoE of course. Cisco calls PPP a method too: https://www.cisco.com/c/en/us/tech/wan/point-to-point-protocol-ppp/index.html
