Do I need to buy Cisco press books? Tell me which other books I need to purchase. Any suggestions to prepare, how many hours/week to prepare ? Any practise books are necessary? which kind of practise books? Please help me out reagrding this. I'm in confusion now.Suggest me a best way to get CCNA certified.
