I lurk more than post around here but thought I could give my take on the certification exam. 833/900

Study Materials used:
CompTIA Security+ by StewartCompTIA Security+ by LaChance
There are questions about cloud computing and virtualization which has been mentioned previously. I also feel that study materials for 201 would aptly prepare somebody for 301. The areas I would stress in studying are: Access Control, SSH: (SCP, SFTP), hash types, encryption types, especially the differences between hashes and what they do opposed to encryption algorithms and their purposes and implementations. Lastly, I can say that the Sec+ exam was much easier than the Net+ exam for me.
