This is a Cisco CCDE Practical exam demo scenario.

Please provide your Name and Email and click ‘ Start Quiz ‘ button below to start the CCDE demo scenario.

There are 34 questions in this exam. In the real exam, 25 to 35 questions are asked generally.

You will have two hours and you cannot go back to previous question when you select your answer.(Similar to real exam)

Some questions are single choice, some of them Multiple choice. For the multiple choice questions, partial scoring applies (Same in the real exam)

There are migration questions,similar to real exam and partial scoring applies for them as well.

Passing score is 80 similar to real CCDE exam.

Throughout the scenario, you will receive an emails again this is similar to real exam.Emails will provide extra bit of information and will redirect you to new set of problems.

Answers will be provided when you finish all the questions.

This is the most realistic CCDE Practical demo scenario available on the Internet and for more Scenarios and the detail explanation of this scenario, please register to the DesignWorld or any upcoming CCDE Bootcamp.

  1. we got following Observations regarding network which should be cured to improve high availability of the network
    1- WAN SMT links Topology 1 and 2 have single point of failure .
    2-SMT DC topology Core has point of failure if any one core switch goes down there will be failure as there is no redundant connection from distribution to core .
    3- SMT DC topology access switch ,1,50,51,100 has single point of failure.
    4- rmt pop2 to DC1 there is single point of failure.
    5- In RMT DC topology aggregation switch could be further linked with core switch to enhance redundancy

    • Hi Usman, Thanks for the feedback but whole purpose of this exam is to fix the issues if it is Customer’s concern too. Whatever you see in those topologies may not be the concern of that customer.

      Actually not only in the exam but also same in the real-life. For the high availability, you may want to eliminate single point of failure but single point of failure may not be the concern of them at all.

      Thus, you need to focus on customer’s expectations, if customer asks you , any design recommendation regarding high availability, then maybe you can address some of them.

      You need to understand first which site is critical, which one is not, is there a budget concern to add more device,links etc , is there a networking stuff to manage new network, is high availability bringing new set of challenges and whether those challenges can be addressed by the existing stuff or need a learning curve etc.

  2. Hi Orhan,
    First of all – congratulations for the scenario and the effort to make it similar to the real exam! This is really useful for guys who want to see how the exam looks like.
    During my attempts (I made 3 attempts, first one was with 56%, second and third with 57%) I noticed few things:
    1) Question N1 .. actually is not a question, it’s only an information
    2) Question N2 really confused me. On Question1 we saw email 1 and general information for both RTM and SMT providers and suddenly on Qestion2 – there is email 14 (where are the rest 12 emails?) saying something for acquisition of a 3rd provider based in UK… this is really not in place, according to me.
    3) On question 23 – there are two times “IS-IS between PGW1-ASBR1”
    4) On question 29 – “Is there any problem for LDP and BGP based VPLS to support end to end VPLS ?” – I was really confused by that question. From a general point of view – VPLS with T-LDP signaling is not a scalable solution (that’s why there is H-VPLS -> BGP signaling and even better PBB+EVPN), from a scenario point of view – it seems that they want LDP signaling with BGP auto discovery. I really don’t know how to answer it.
    5) Question N33 is not clear for what a “short term solution” is needed – for merging both providers or for UK provider acquisition. It was already mentioned in Question2 regarding a “short term solution”, but here it’s a little bit confusing for me.
    Maybe Question 2 should be at the end of the scenario, before Q33?
