You only need one book -

http://www.amazon.co.uk/CCNA-sup-small-Certified-Associate/dp/0782143911/ref=pd_bbs_sr_1/026-6050047-9939647?ie=UTF8&s=books&qid=1190582232&sr=8-1

Contrary to what anyone will tell you, the CCNA is an absolute  piece of piss. If you have any background in TCP/IP you will sail through it (Once you have brushed up on subnetting, as I remember there were a lot of subnetting questions)

You can do all the studying you need to pass it in a few days, although it helps if you work with the stuff on a daily basis like I was/am.

There will be one or two topics you struggle with.  But I do agree with mark.  Put your head down and anyone can do it.

A knowledge of TCP/IP helps a lot.

The CCNA is easy.

This is backed up by the amount of complete muppets that come to interviews with their CCNA certificate in had yet know nothing about networking.


Good luck with it but please take the time to use the theory in practice (even if its at home).

Cheers for the advice guys. I do work in TCP/IP (Im network admin for a BT division) mainly working in Server 2000/2003, AD and Citrix. Career wise I want to move into Cisco - either pre sales or preferably as an engineer. Our systems are all based on Cisco routers, switches and firewalls which are looked after by our engineers (our division primarily sells and installs Cisco solutions) so in the short term I want to be able to look after this part of our infrastructure myself. Quite lucky really as I work daily with CCNPs and CCIEs so lots of tips and help when I need it and plenty of exposure to the kit.
