I've been configuring and maintaining our company's 6 cisco routers and 1 pix firewall for the past 3.5 years. I've had it as a goal to quickly add the CCNA certification and move on to either a higher level cisco cert or microsoft. I purchased a cbt nuggets training set for ccna and started working through it, thinking I would get through it relatively quickly. I was surprised by the volume of topics it was trying to cover, and I thought the CCNA was supposed to be the "entry-level" cert - I can't imagine how much volume there must be for the CCIE, for example? Has anyone taken the CCNA cert test that can offer some perspective on how extensive the subject matter is? I guess I figured that, being a net admin and having years of experience on cisco eq and ms networks, the CCNA would be a 'short-order' cert, but it's taking forever, and I'm not slow to learn either..... (Am I working too hard at preparation for this exam, or is it really that extensive)?
