Final correction : CCNA = Cisco Certified Networking Associate,
why I know ? Just picked up my first certification with it. 3 years experience with routers and that little piece of paper will get your foot in the door almost anywhere.
Now CCNP ? (network professional) ... that's where the money starts coming back in.
I expect the demand for people who can work with routers and switching equipment to last for a while. We still have a conversion to IPV6 to get through, and a lot of firewalling and data stream encryption to do.
