  • 第1题:

    Which line from the output of the show ip interface command indicates that there is a Layer 1 problem?

    A.Serial0/1 is up, line protocol is down

    B.Serial0/1 is down, line protocol is down

    C.Serial0/1 is up, line protocol is up

    D.Serial0/1 is administratively down, line protocol is down

    E.None of the above


    正确答案:B
    解析:Explanation:
    When the physical interface itself is down, then the problem is related to layer 1. When it is up, but the line protocol is down, then the problem is related to layer 2.
