I'm pretty sure that with my experience with IOS up to this point I could pass the CCNA test with a little brush up, but I have to keep the PIX at work running correctly and it's thrown my some curveballs. (I'm a geek and I HATE not being able to make it do what I want it to!
)
I've been through the learning partners on Cisco.com and I'm finding precious little in my area for the CCSP class I'm interested in, though I may be looking in the wrong place!
