Thought I'd let you know that the Exam Cert Guide book (3rd edition) is jam packed with good info.
I've been sceptical in the past (remember the old CIT book - pointless).
Anyway this book helped me pass the above exam with 100% which nearly made me fall out of my chair.
I know some of this is down to experience since I've been around Cisco products for about 8 years but I was amazed how good this book was.
Definitely a recommendation in my eye's.
Hope this helps anyone in their persuit with this cert..
