Which WAN encapsulations can be configured on an asynchronous serial connection?

PPP
ATM
HDLC
SDLC
Frame Relay

1 and 2

2 and 4

3, 4 and 5

All of the above

Answer: Option

Explanation:

Please do not freak out because ATM is an answer to this question. ATM is not covered in depth on the CCNA exam. PPP is mostly used for dial-up (async) services, but ATM could be used as well, though it typically is not used anymore since PPP is so efficient.
