I've been told by many people that you can only take the Cisco and Microsoft exams so many times, and each time the pass rate is raised. The thought of failing and being banned from ever taking the test again scares the hell out of me, though I would prefer to think positively and look forward to a pass.

However, I recently looked on Cisco.com and didn't see anything regarding this. Does it actually exist, or did my teachers fool me? ;_;
My other question was about taking the test online. I hear they give you this option, though I intend to take it at a test centre. Is this only for people who already possess the CCNA and simply wish to renew it?
