i was checking the course contents and seem i have to deal with command lines also !!I took one back during Highschool. It was rather tough... A fair amount of command line configurations were required for the routers, subnetting (I can ramble off almost all my powers of two now) Eh...and other things but those are what stand out the most.
yeah, anyway it's good to learn new stuff, but hopefully i won't screwWell, I am attending Cisco Fast Track course,
IP routing, subnetting also good stuff to study
The difficulties start with Dynamic protocols such as EIGRP, OSPF, and things like that
but it worth being challenged to it.
I have a friend who just got his CCNA and he said the course was pie if you have basic knowledge...
