Which of these WAN encapsulation types can be configured on an asynchronous serial connection?
  1. HDLC
  2. SDLC
  3. Frame Relay
  4. ATM
Explanation
Answer - D - ATM is the WAN encapsulation type that can be configured on an asynchronous serial connection.

Key Takeaway: ATM, or asynchronous transfer mode, is a dedicated-connection switching technology that organizes digital data into 53-byte cell units and transmits them over a physical medium using digital signal technology. ATM is designed to be easily implemented by hardware; hence, faster processing and switch speeds are possible. Speeds on ATM networks can reach 10 Gbps.
