DNC = Did not complete.
* Includes reading the exam, creating L2 diagram, and initial troubleshooting. 
** Includes creation of TCL scripts and macros.

Notes on specific tasks:

1.1 – I did not put sw1 and sw2 into vtp transparent mode because I never attempted task 1.6 (private VLAN).  I’m not sure if I would lose points for this or not.

1.4 – Stupid mistake #1.  I did not read this question closely.  I would have configured it correctly if I had paid attention to “[ports] will be shut down”.

1.6 – I recognized that this task required private VLANs, but I couldn’t get my head around exactly what the configuration should look like.  I skipped this task rather than risk breaking my network.

5.2 – Stupid mistake #2.  I configured the same router instead two separate routers.  I had the right configuration, but I didn’t switch from r2 to r3 so I ended up putting the entire configuration on r2.

6.3 – Stupid mistake #3.  I forgot to configure the IPv6 hostnames on the routers.

7.1 – Stupid mistake #4.  I configured DLCI 513’s be value on DLCI 504 and vice versa.

7.2 – I used CAR instead of MQC.  I can’t find anything in the question that requires MQC.

9.2 – The task states to “configure all devices in the network” and gives specific ‘logging facility’ values for all devices except sw2 and sw3.  I configured the defaults on those two devices, but the solution guide seems to skip them altogether.

9.3 -I configured ‘ntp peer’ on both r3 and r6.  It is only needed on r3.  Not sure if I would lose points for this or not.

This was my first simulated mock lab.  I limited myself to 8 hours (with a 30 minute “lunch” break).  I have mixed feelings about my experience.  One one hand, I did very well on the core topics.  I aced the IGP and Frame Relay sections.  I nailed the IGP route redistribution (albeit a pretty simple scenario).  I was done with everything up to BGP with the exception of two layer 2 tasks (I completed one of them later) before lunch.  I ran my TCL scripts and ping macros before lunch and then reloaded the routers.

After lunch it was a different story.  I spent over an hour on the first BGP task.  This was a very simple peering task.  For the first time in any lab I had to create a BGP map.  It really helped me out, especially with placing route reflectors.  I spent a ton of time troubleshooting a single peering that would not come up.  It turned out to be a boneheaded mistake.  I configured a neighbor address of 181.13.125.x instead of 181.13.123.x.  ARRGGHHH!!!

I knew that I was not likely to get 80 points as there were a number of tasks which I had no clue as to how to complete.  By the time I was done with BGP, I had about 2.5 hours to complete the remaining 49 points (plus 4 points I skipped in Bridging and Switching).  I knew after reading the lab that I was only going to be able to count on getting about half of those points.  I missed some of these points because of stupid mistakes, but I also picked up some points by mining the DOC.  But in the end, I left 20 points on the table by not attempting/completing the tasks.  While I rocked the core routing section I failed miserably down the stretch.  This is not a surprise as I have been doing a lot of core routing work and only scratching the surface of the non-core tasks. 

I felt pretty good about my time-management skills other then the hour I spent on BGP peering.  It is VERY different trying to complete a lab in 8 hours.  I felt the tyranny of the clock.  Also, I really haven’t logged eight uninterupted, consecutive hours on a rack before.  I was a little punch drunk by the end.  I only missed a couple of (dumb!!!) points due to question interpretation. 

This was IE’s easiest lab and I failed it, so I don’t feel great about that.  On the other hand, I nailed the core tasks and did a pretty good job of managing my time.  As usual, I feel like I’m taking one step forward and 0.99999 steps backward.  🙂

  2. It sounds like you did great — the first simulated 8 hour stretch has to be rough. I just did this lab last week (broken up over a couple of days) and ran into some of the same things (rate limiting instead of MQC, ntp peering). I am still verifing w/ the solution guide as I go through each step, so I’m a little nervous for when I have to move to the full test scenario. I guess I will really have to improve on my verification methods. Hopefully I will be as successful as you were this time. It’s a great step in the right direction. Thanks for sharing.

    Cheers!

  3. One thing I’ve learned–it’s in troubleshooting those stupid mistakes for an hour that the learning really happens. I’ll bet you spent a lot of time using show and debug commands you’ve barely touched before. If it happens again you’ll find the root of the problem much faster. I promise, you will mess up typing an IP address on the actual lab. It happened to me on my first attempt (second attempt coming in March) and cost me a half hour. The mistakes will happen–you just have to be able to find them quickly.
