Which encapsulation type is a Frame Relay encapsulation type that is supported by Cisco routers?

The correct answer is A. IETF. Cisco routers support two Frame Relay encapsulation types: 'cisco' (Cisco-proprietary, the default) and 'ietf' (Internet Engineering Task Force standard, used for multivendor interoperability). IETF (A) is the correct answer. ANSI Annex D (B) and Q933-A Annex A (C) are LMI…

Explanation

Cisco routers support two Frame Relay encapsulation types: 'cisco' (Cisco-proprietary, the default) and 'ietf' (Internet Engineering Task Force standard, used for multivendor interoperability). IETF (A) is the correct answer. ANSI Annex D (B) and Q933-A Annex A (C) are LMI (Local Management Interface) types used for signaling between the router and the Frame Relay switch - they are not encapsulation types. HDLC (D) is a separate serial encapsulation protocol, not a Frame Relay encapsulation type.
