    Default A question about Frame Relay in CCNA exam

    Hello, I very would like to discuss with you about the following question:

    TheFrame Relay network in the diagram is not functioning properly. What is thecause of the problem?


    A.The Gallant router hasthe wrong LMI type configured.

    B. Inverse ARP isproviding the wrong PVC information to the Gallant router.

    C.The S3 interface ofthe Steele router has been configured with the frame-relay encapsulation ietfcommand.

    D.The frame-relay mapstatement in the Attalla router for the PVC to Steele is not correct.

    E.The IP address on theserial interface of the Attalla router is configured incorrectly.

    The answer said that it is "D", I think the mapping in router Steele is not right neither, because the IP address in the mapping should be the destination address, but in the exhibit, the ip address in the mapping of Router Steele is his own ip address, so I think this is wrong, what you guys think about?

    You're right. The frame-relay map statement on Steele is wrong too--it loops back to itself. So if the map statement on Atalla was corrected, but the map statement on Steele was not, there still wouldn't be a functioning PVC between Atalla and Steele.

    But since this is the only correct answer you should pick answer D, even if there's another cause making it not functionning properly.

    The Steel router has mapped to itself.
    This is one of those questions that you have to guess which one does Cisco say is wrong....the Steel router can't go anywhere, and the Gallent router can only send to Steel, and the Attalla router can only send to Gallent.

    However, I would answer "D", because that is the only correct wrong answer in this!!
