I hope to be passing my CCNA here in a few months. On urging by several people that have stated it be best to just run in and get my CCNP while I am at it.
My work has a CiscoPress series of books for passing the CCNP but I have no idea how old they are, as they have no exam numbers on them. They are copyright 1999 so at most 8 years old. Is there a large difference, and would I be putting my studying in jeopardy by studying with what could be older material?
