Red Hat Certified System Administrator (RHCSA)
The performance-based RHCSA (Red Hat Certified System Administrator) exam (EX200) tests your knowledge and skill in areas of system administration common across a wide range of environments and deployment scenarios. You must be an RHCSA to earn a Red Hat Certified Engineer (RHCE) certification. The skills tested in this exam are the foundation for system administration across all Red Hat products.
An RHCSA certification is earned when an IT professional demonstrates the core system-administration skills required in Red Hat Enterprise Linux environments.
Red Hat System Administration I
This course relates to Red Hat Enterprise Linux (RHEL) 7. Red Hat System Administration I (RH124) provides a foundation for students wishing to become full-time Linux system administrators by introducing key command line concepts and other enterprise-level tools. These concepts are further developed in the follow-on course, Red Hat System Administration II (RH134).
IT professionals across a broad range of disciplines who need to perform essential Linux administration tasks including installation, establishing network connectivity, managing physical storage, and basic security administration.
There are no formal prerequisites for this course; however, previous operating system administration experience will be very beneficial.

Red Hat System Administration II
This course is specifically designed for students who have completed Red Hat System Administration I (RH124). Red Hat System Administration II (RH134) focuses on the key tasks needed to become a full time Linux administrator. This course goes deeper into enterprise Linux administration including file systems and partitioning, logical volumes, SELinux, firewalling, and troubleshooting. Attending both Red Hat System Administration I and Red Hat System Administration II can help you in your preparation for the Red Hat Certified System Administrator exam (EX200).
This course is singularly designed for students who have completed Red Hat System Administration I (RH124). The organization of topics is such that it is not appropriate for student to use RH134 as a curriculum entry point. Students who have not taken a previous Red Hat course are encouraged to take RH124 if they are new to Linux.
