I use Exam Cram and TroyTech study guides to pass the CCNA. I also had 4 semesters of hands-on training at a Cisco Networking Academy. As far as just getting the Certification, I could have definately passed it withought the classes. I thought it was very easy. But if you are going to be dealing with Cisco Routers much or plan on making a career out of it, then I recommend the hands-on training. Travis McGuire
