3. Do WAN protocols also rely on TCP for guarantee delivery?
Ans. These are all Layer 2 protocols. They don't care for upper layer protocols. They work the same way for ppp/Fr as for ethernet. Layer 3 and above work the same way
4.I also read somewhere, PPP does not use destination address over WAN. Why is that?
Ans. What destination address? If you;re talking about Layer 2, PPP doesn't need this because as the name says, it's point to point. It expects only 1 device on the other end of the wire so why would it need a Layer 2 destination address? Layer 3 is the same as ethernet
Try getting a good book (BCRAN would do), or install GNS, capture packets and see for yourself.
