Checking Lab Challenge 3 (VTP, STP, EtherChannel)

March 31st, 2016 Go to comments

You are tasked to check the network configuration of a new company and answer some related questions. This company has four switches connected as shown in the topology below.


This is the link to access this challenge: https://www.9tut.com/lab_challenges/Checking_Configs_Switch/

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.

    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.

    Where can I access the answer and explanation?

    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?

    Nice lab, but is it taken from real CCNA exam almost like it was, or is it just a good practical example ?
