I just wrote the CCNA exam today and I am in need of a resource that will give me the edge I need for a pass and of course the best understanding of routers and switches.So far I have used multiple resources.Cisco press books from mcQuerry and Odom. Odoms books were excellent but just short of the mark. I need a simulator type product which is fully functional and easy to use like the Boson simulators found in wendells exams. If those simulators had been a little more extensive I probably would not be writing this now. There was no debug support. I also could use a test simulator as close to the CCNA exam as possible. I would appreciate any help to get me from 79.8% to 100%. I have put a lot of time into this and I would like to finish on the next write.
