3rd Mock Lab - 97%

This was the first mock lab, i finished in about 7,5 hours! Of course it took me another 1,5 hour to review all of it and correct 2 "mistakes". But generally, i'm quite satisfied by the result.

There were 3 topics i had to look at the DocCD; one of them was complete unknown to me (MVR - Multicast Vlan Registration). I just knew there was a feature which provided the functionality i was asked for, but i didn't know, neither its name, nor its configuration. As it proved out, it wasn't so difficult.

Finally, to be honest, i believe i should have been graded with a 91%, because there were another 2 tasks that i didn't complete 100% according to the solution provided. I know that sometimes there are many correct solutions to each task, but i think (after looking the vendor's solution) that my own solutions weren't so correct.

On the other hand, there were 2 tasks that my solutions were correct and the ones from the vendor were probably wrong. That's because one task was influenced by changes near the end of the exam (new routes introduced) and the other one wasn't meant to be tested (full reachability while a backup link was active). If i hadn't checked all the questions one more time, i wouldn't have found them. Especially the second one, it took me some time until i come up with a solution; i was trying to find out why an OSPF router was load-balancing between a correct path and a "wrong" path, when the "wrong" path was through a totally NSSA area which was having a default route back to this router. So i was getting a loop there. I finally changed the cost in order to avoid the NSSA area and everything worked fine.


Today i'm having my second CCIE Assessor Lab... hoping for something >80% this time.
