I currently hold a CCNA, and I work as a sales engineer for an ILEC/CLEC. I have the text for the CCDA, but didnt know if I needed to go get my CSE first? I think it would be a waste of money really, but not sure. Also there is no evaluation on the Cisco site so I dont know how in depth I need to study. If any one has a legitimate PRACTICE test (not the cheats)please let me know, I would like to try it.
