RHCSA - Rapid Track Course - RH199

Course overview

On completion of course materials, students should be prepared to take the Red Hat Certified System Administrator (RHCSA) exam.
Note: This course builds on a student's existing understanding of command-line based Linux system administration. Students should be able to execute common commands using the shell, work with common command options, and access man pages for help. Students lacking this knowledge are strongly encouraged to take Red Hat System Administration I (RH124) and II (RH134) instead.

Audience

Students for this class should have 1-3 years of full time Linux administration experience
