Which encapsulation type is a Frame Relay encapsulation type that is supported by Cisco routers?
Click on the arrows to vote for the correct answerA. B. C. D.
The correct answer is B. ANSI Annex D.
Frame Relay is a Layer 2 WAN protocol used to connect multiple sites in a network. Frame Relay uses virtual circuits (VCs) to provide connectivity between sites. Cisco routers support different encapsulation types for Frame Relay. Encapsulation type determines how data is formatted and transmitted across the network.
The options provided in the question are:
A. Q9333-AAnnexA: This is not a valid Frame Relay encapsulation type. It is likely a typo, as the correct name is Q.933A Annex A. This protocol is used for ISDN connections.
B. ANSI Annex D: This is a valid Frame Relay encapsulation type that is supported by Cisco routers. ANSI stands for American National Standards Institute. This encapsulation type is used in North America.
C. HDLC: HDLC stands for High-Level Data Link Control. It is a protocol used for serial communication between devices. It is not a Frame Relay encapsulation type.
D. IETF: IETF stands for Internet Engineering Task Force. It is a standards organization that develops and promotes Internet standards. It is not a Frame Relay encapsulation type.
In conclusion, the correct answer is B. ANSI Annex D.
