Note: You are not allowed to configure anything by company policy. The network is operating correctly so just use various “show” commands to learn how this network works.

    @bodi: You need to type your commands into the small boxes to get the output.

    Why is it that not all show commands work?

    @Nick: Currently our simulator does not support all show commands so only popular ones are supported.

    Please can you explain question 7? You provided the answer as SW1-SW2-SW3-SW4. I think the answer should be SW1-SW2-SW4 because of the cost factor.

    Thanks

    9tutlover the answer is “SW1-SW2-SW3-SW4” because of the spanning-tree port roles
    Notice in which vlan the PC1 is conected to, then Issue the “show spanning-tree vlan X” and follow the path between the trunk links, you will notice that int E0/3 in SW4 is in discarding role.

    Rul, but PC1 belongs to the vlan 15
    on E0/3 SW4 is BLK.
    So the answer will be “SW1-SW3-SW4”

    I thought it was sw1-sw3-sw4 at first… However, sw2 is root and the e0/3 to sw4 is in blocking/discarding. So, That means it has to go sw1-sw2-sw3-sw4. .. Anyone like to confirm?

    So do i access these labs. When i click on the link, all it does is give me some buttons that show gray squares and that is it.

  17. Question 2
    August 18th, 2017

    The correct answer for # 2 is indeed 1,5,10,20. SH Spanning Summary shows but the quiz says that the correct answer is 1,15,20. Also, the question tells you to select 4, yet there are only 3 correct answers?
