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.

    I took the test today, but I did not pass. I made 750. This simulation is no longer valid. I studied several simulations, but the test changed. Tickets are still valid.
    The test contains new multi-choice questions and a BGP lab. No multiple choice question is contained in the dumps.

    Wow, new exam today. 19 questions. About 9 tickets from old exam. New iBGP-eBGP ticket. Life has changed…Old prep will NOT make a passing score. Some pof the former tickets seemed to have no “issues” that I could find with the running config. I pass every exam for 14 years, and failed badly today on TSHOOT!

    Today I passed my TSHOOT exam with 975 points and re-certified my CCNP/CCIP. A lot of the tickets were the same. One new ticket with iBGP/eBGP. Here was a AS mismatch (iEGP), wrong neighbor address (eBGP), wrong mask on interface.

    + OSPF is running among R3, R4, SW5 and SW6, all are in Area 0


    + OSPF is running among R1, R2, SW5 and SW6, all are in Area 0

    Welcome to your post. You are wishing to study CCNA or CCNP or higher CCIE as you have no documentation for reference and practice. Do not worry. I have gathered a lot of documents related to CISCO on google drive and the cost to you own this repository is 200k or $ 10.
    This is a link you can access.
    You can preview in your google Drive what it is through:
    Like and subscribe my channel.
    Ok wish you study effectively, through your ebook.

    IMHO – GNS3 would be better than to work on separate flash simulators. As long as you show the IOS version and how interfaces are setup. then it’s more real life.
