You need to configure a router for a Frame Relay connection to a non-Cisco router. Which of the following commands will prepare the WAN interface of the router for this connection?

[A]. Router(config-if)#encapsulation frame-relay q933a
[B]. Router(config-if)#encapsulation frame-relay ansi
[C]. Router(config-if)#encapsulation frame-relay ietf
[D]. Router(config-if)#encapsulation frame-relay cisco

Answer: Option C

Explanation:

If you have a Cisco router on one side of a Frame Relay network and a non-Cisco router on the other side, you would need to use the Frame Relay encapsulation type of IETF. The default is Cisco encapsulation, which means that a Cisco router must be on both sides of the Frame Relay network.
