Troubleshooting Lab Challenge 1

April 19th, 2015 in Lab Challenges Go to comments

Note: We created this lab challenge to help you get some practice with networking problems only. These labs are only for fun and do not appear in the TSHOOT exam. Please let us know if you like this simulator or not so that we can continue making other simulators in the future. Any suggestion, recommendation, error reports are warmly welcomed!

Troubleshooting Lab Challenge 1:

A network engineer has edited their network configuration and now your customer is experiencing network issues. Some reports said that users connected to CLIENT router (R4) cannot reach the services located at SERVER router (R3). They have contacted you to resolve the issues and return the network to full functionality.


To troubleshooting effectively you should understand how this network works. We summarize it as follows:

+ OSPF is running among R1, R2, SW5 and SW6, all are in Area 0
+ R1 and R2 are two DHCP Servers
+ R1 is only responsible for answering DHCP Request from SERVER (R3)
+ R2 is only responsible for answering DHCP Request from CLIENT (R4)
+ Interfaces E0/0 of SERVER and CLIENT is running DHCP to request IP addresses
+ There is an access-list named “edge_security” on SW5 that prevents devices with source IP of 172.16.0.x from accessing the SERVER.

There are 9 tickets waiting for you to resolve. Below are the links to access them:

Ticket 1 Ticket 2 Ticket 3 Ticket 4 Ticket 5
Ticket 6 Ticket 7 Ticket 8 Ticket 9  

Please try your best to solve these tickets!

You can find the solution and explanation for each ticket here.

    Hi guys,
    on this page above, ticket 2, I can not see the issue on SW6. Client pings it GW but can not ping any direct interface on SW6. SW6 blocks the ping back somehow, any clue ?

    Hi networktut team,

    In Q4, entering sh ip dhcp pool command on R1 shows 1 leased address.
    Shouldn’t it be 0 considering ip helper-address missing and dhcp request has not reached R1 ?

    Unlike CCNP router, doesn’t TSHOOT have a drag& drop question?
    i looked up whole pages of dump, i couldn’t find any of it. maybe i could let it go and go to take an exam…. but i want to know just in case.
    could you share your experience as an answer to my question? thanks~

  46. Cisco Certification
    September 22nd, 2016

    Hi Guys,
    I need your assistance in identifying some of the changes that has occurred in the Cisco certification area?
    1. Actual test as I knew had very good study material and there are no Cisco study questions on that site ?

    2.9tut also had very good materials, question and answers but at the moment there are none?
    Does anyone know whats happening?
    Which question are we suppose to revise before sitting for the grilling cisco exams.

    Just through experience you could know all the material of cisco “hypothetically speaking” and yet still fail, because the revision of the exams was not done.
