Hi everyone, can anyone pls advice as to the best books and simulator to buy to prepare for ccna and how long I should take to prepare for it, I've just passed network + exams and im looking at going into network administrator roles.
Many thanks

I used the Cisco Official Cert Guide by Odom, CBT Nuggets, and Chris Bryant I was more than prepared going over those materials. CBT Nuggets was the best source for me, but it probably is a bit too light.
