TO be honest I thought it was very safe forward and had no difficulty taking it. I do see the basic concepts for CND purposes, however I do not understand the hype on it. For as simple as it was I am great full I passed. What I used to study is listed below:
SKill Set Pro
C|EHv9 form Sybex
The practice test from Blockmon for CEHv9
That was about it. The test itself is pretty straight forward and only requires a little studying depending on your background. If you have worked in a JOC, NOC, or SOC then you should do just fine. If you haven't then you should brush up on a few things do some practice tests get Security + first then take C|EH.
