Hi,
I've been looking at a few jobs and there seems to be a high demand for CCNA. I've been working in IT for five years now and everything I think I'd use a cisco box for I've done with linux i.e. routing, VPN's, SSL VPN etc....
My question is where are the free resources for CCNA study? Is there a free virtual cisco box I can play with? How hard is the exam if I have a basic understanding of most of the concepts?
Thanks,
IS
