I will be taking my Security+ exam soon. Just wanted to know what people thought of the exam and what areas you recommend to focus on. I have studied the All in One Security+ book by Gregory White and some of the Shon Harris All in One CISSP (I want to eventually take the CISSP in the far future and having a Security+ cert. counts for a year experience). I hear many people have purchased a study guide that is "king" for helping people pass the test. Is this a worthwhile investment, or am I better off relying on these books? Are there any free practice test sites you recommend? Thanks.
