Will studying for the CCNA 640-802 also prep me for the ICND1 and 2 exams? I ask this because in case I decide to take the 2 exam route, I dont want to spend money on the ICND study material if they are all related. The book im using now is the Todd Lamle Sybex 6th edition CCNA 640-802 and the CCNA fast pass along with Transcender test engines. Any feedback would be great. Thanks
