About this Course

Red Hat System Administration I (RH124) relates to Red Hat Enterprise Linux 7 and is designed for IT professionals without previous Linux administration experience. The course focuses on providing students with Linux administration "survival skills" by focusing on core administration tasks. System Admin I also 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). Both courses are needed in your preparation for the Red Hat Certified System Administrator Exam (EX200).
