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

  1. PPP
  2. ATM
  3. HDLC
  4. SDLC
  5. Frame Relay

[A]. 1 and 2
[B]. 2 and 4
[C]. 3, 4 and 5
[D]. All of the above

Answer: Option A


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.
