A follow-up course for students that have completed Red Hat® System Administration I (RH124), Red Hat System Administration II with RHCSA Exam (RH135) is designed for IT professionals working to become full-time enterprise Linux® system administrators. Building on the foundation of command-line skills covered in System Administration I, students will dive deeper into Red Hat Enterprise Linux to broaden their toolkits of administration skills. By the end of this course, students will be able to administer and troubleshoot file systems and partitioning, logical volume management, access control, and package management. Students who attend Red Hat System Administration I and II will be fully prepared to take the Red Hat Certified System Administration (RHCSA) exam.
Note: This course is intended to be taken following Red Hat System Administration I and does not cover all RHCSA exam tasks. Students with solid Linux command-line skills seeking to take only one course before attempting the RHCSA exam should consider the RHCSA Rapid Track Course (RH200).
