This page is a directory that links to posts I have done that cover the official objectives in the Red Hat Certified Engineer (RHCE) 7 exam. Basically if you need to know detailed information on any of the objectives below simply click the link for further information. I created these posts while studying for the RHCE EX300 exam myself, I passed it with a score of 281/300.
The official objectives for the RHCE 7 exam can be found here and are covered below.
Below is a list of material I used to study for the RHCE exam, I found that these books complemented each other well and provide an easy to follow explanation of the objectives.
