This is the RHCSA Study Guide for the System Administration Study Group.
The study guide is intended to be printed by those who wish to study common tasks performed by many system administrators. This study guide is based upon the Red Hat Certified System Administrator Exam Objectives. Other useful study components will be added here. Community contributions are always welcome.
