In my final preperation for the RHCSA I've gone through and found some good references for a "cheat sheet," pulling from Michael Jang's RHCSA/RHCE study guide as well as this fantastic wiki: http://rhce.co/rhel6/Main_Page for those seeking their RHCSA.The RHCE portion is incomplete, but the RHCSA part is complete and only slightly outdated. It is a fantastic resource.
Between those two sources, notes from Tommasino's Hands-on Guide to the RHCSA/RHCE, and my personal knowledge, I put together this study guide based on the RE200 exam objectives as of 2012 05 15.
