TRAINING COURSE OVERVIEW

This 4 day course covers the same topics as the Red Hat System Administration I (RH124) course. It is designed for IT professionals without previous Linux administration experience. The course focuses on providing students with Linux survival skills by focusing on core administration tasks.

Red Hat System Administration I 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, which covers the same topics as the Red Hat (RH135) course.

The course is part of the preparation for the Red Hat Certified System Administrator (RHCSA) exam. This performance based exam (EX200) tests the users knowledge and skill in areas of system administration common across a wide range of environments and deployment scenarios.


AUDIENCE

End Users of Redhat Linux who intend to start maintaining a Linux system at command-line level and who need to gain hands-on experience of troubleshooting and system administration of Linux systems.
