RHCSA/ RHCE Red Hat Linux Certification: Exams (Ex200 & Ex300) (Certification Press)
"Certification Book of the Week: 'RHCSA/RHCE Red Hat Study Guide'While its primary purpose is to serve as a study guide, the  book doubles equally well as a reference ... All in all, it is a great book and one that anyone working with  RHEL 6  will want to have.    "Emmett Dulaney, Associate Professor, in a review at CertCities.comRHCSA/RHCE Red Hat Linux Certification Study Guide, 6th Ed is "also a very useful book if you simply need to learn more about administering Red Hat Linux systems in your workplace...I like the conciseness of this book."
