However, here are the main things I concentrated on before my exam:1) Get a good understanding on how to setup each routing protocol - especially the network statements. I just remembered how to setup RIP and OSPF - then I just know that EIGRP can do their NETWORK statements either the RIP or EIGRP way. And understand what the NETWORK statement actually is doing (advertise route AND turn out the RP through that interface). 2) CDP is your friend - learn it and know it well. You can learn a great deal about your network with SH CDP NEI and SH CDP NEI DETAIL. 3) Get the Boson practice exams and run through them. They are a very good representation of the actual exam. 4) Fully understand what happens at layer 2 and 3 as the packet/frame travels across routers from source to dest. And for that matter have a pretty good understanding of all layers of the OSI model. 5) Have a good understanding of WAN setup and different technologies with WANs. The CBTNUGGETS videos explain this VERY well. 6) Get the Cram Session from CBTNUGGETS ($24 per day for up to 7 days). I used it for 3 days and that $72 probably got me 100 points on the actual exam. I spent about 20 hours over the 3 days just watching the videos and I learned a great deal from them - they just filled in any holes I had in my knowledge. But I would recommend doing the videos AFTER reading the books. 7) Know all the stuff concerning VTP and STP. Basicallly VTP modes and how/when data might get updated or overlaid. For STP have a good understanding of the port modes for STP and RSTP - and understand the root bridge. Know what it takes for OSPF and EIGRP routers to form neighbor relationships.9) Know as many of the show commands for everything from SH VER to SH IP OSPF... These were the main things I made sure I knew very well before the exam. Overall the exam was not as hard as I had feared, but I spent a great deal of time labbing and just playing around with my routers and switches and I tried to break stuff and then fix it back. On a side note - yesterday I decided to upgrade the IOS on one of my routers - and like an idiot I deleted the old IOS before testing the new IOS. Somehow the new IOS got corrupted and I got to learn how to use TFTPDNLD and ROMMON on the fly. I learn a great deal more from my screw ups than I ever learn from doing things right. Good luck to everyone with this exam. If you use the Odom books, the CBTNUGGETS videos and the Boson practice exams you should be ready to go...
