The RHCSA Rapid Track Course (RH199) relates to Red Hat® Enterprise Linux® 7 and is designed for students who already have significant experience with Linux administration. The course reviews the tasks covered in Red Hat System Administration I (RH124) and II (RH134) at an accelerated pace. 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.
