I used the V2 Wendall Odom book which actually covered everything pretty well apart from IPV6 and theres plenty of resources to describe the basics of that.
The Practice Tests with that book are great. you won't find any identical questions on the exam but if your getting good marks on those and understand the reasons for the answers as opposed to just trying to remember them then you'll do fine.
I also read Brad's (CC Bootcamp's) Written study guide during the last week which helped consolidate things.
Now onto the hard stuff.
