The two routers have had their startup configurations cleared and have been restarted. At a minimum, which option below must the administrator do to enable
CDP to exchange information between R1 and R2?
- A. Configure the router with the cdp enable command.
- B. Configure IP addressing and no shutdown commands on both the R1 and R2 fa0/1 interfaces.
- C. Configure IP addressing and no shutdown commands on either of the R1 or R2 fa0/1 interfaces.
- D. Enter no shutdown commands on the R1 and R2 fa0/1 interfaces.
If the no shutdown commands are not entered, then CDP cannot exchange information between the two routers.
