Finally, just last Monday, I completed this test and approved with 260 out of 300 possible points. As always RedHat exams are tough, if you are pursuing such certification, there’s a bunch of information, guides, blogs, books that you can look at. However my recommendation will be to stick to only one book, the official exam objectives, and your test machine with RHEL 6. In my case I used the book recommended by a friend: RHCSA and RHCE guide by Damian Tommasino. And a used old laptop with the lab described on the book completed.
