Passed The Security+ Exam
I took my first shot at the Security+ exam, and with a score of 858. It’s great to be past this one.I’ll go over a little bit about the exam here first. Then I’ll explain what I did for studying so others can get an idea of what they can do to prepare for the exam.I think I had about 6 or 7 questions on Access Controls, which most people say there are a lot on this exam. I even had two questions back-to-back that were almost the same with a few words changed. Some of the study material from ProProfs helped me on one of these questions because of a key word that I associated with RBAC.testpassport help you pass any exam!Of course, there were quite a bit of questions on cryptography as well. There was one question on PKI certificates that tripped me up because it wasn’t covered at all in the Sybex or Syngress books, at least that I could remember. I have a lot of knowledge with relational databases; so I used this to try to figure out the answer. I figured, if a Website holds a certificate, and they serve customers, then they have one certificate serving either one or many customers giving either a one-to-many or a one-to-one relationship. However, from what little I could find on the Internet, I believe the relationships are many-to-one and many-to-many. I’m still not exactly sure. I can’t find any explanation for this, and it makes me confused on the reasoning . It’s too bad the books didn’t explain it.
