Practice question

There is this practice question but i think provided answer is wrong. Just to be sure I need input from you guys.



I chose B and C because sh ip int and sh protocols both show ip address as well as up/up status.

where as sh controllers command is just confusing.

    So if you think about it the question is asking for Layer 1 and layer 2 information.

    If you look at show protocols it will show you what protocol is running (ip) and if the interface is up and the line protocol is up (l1 and l2) and yes if you have an IP address then that's in there too.

    Router1>show protocols
    Global values:
    Internet Protocol routing is enabled
    FastEthernet0/0 is up, line protocol is up
    Internet address is 192.168.1.1/24
    FastEthernet0/1 is administratively down, line protocol is down
    Serial0/0 is up, line protocol is up
    Internet address is 192.168.2.1/24

    For the show controllers that gives you the FULL on l1 information.


    Router1>show controllers fastEthernet ?
    <0-9> FastEthernet interface number
    Router1>show controllers fastEthernet 0/0
    Interface FastEthernet0/0

    RX_RING_ENTRIES
    status 8000, len 175, buf_ptr 1DF7680
    status 8000, len 175, buf_ptr 1DF7CE0
    status 8000, len 175, buf_ptr 1DF8340


    show ip int br in strictly showing l2 and l3

    That's what my understanding is.

    Hope this helps maybe i'm wrong and some guru's can correct me

    The other command is sh ip int ---> not sh ip int bri


    and that also shows fa 0/0 is up and protocol is up as well as ip address

    This is where I get confused. :/


    and also sh ip int bri also shows all that info.

    well, I agree with you. B&C I don't see an ip address in the show controllers output above
