Friends:

I have been using the Cisco Press CCNA Self-study INTRO and ICND guides
to prepare for my CCNA exam. I plan to take the combined 640-801 exam.
These books were published in 2004, and I'd like to know if much has
changed since then. If I master these study guides, will I be prepared
for the CCNA exam, or have there been significant changes in the
intervening years? I also have a home cisco mini-lab with a couple
routers running IOS 12 and a Catalyst 1900.

Thanks,

Carlos
