About this course
Red Hat encourages you to consider taking Red Hat System Administration I
(RH124), Red Hat System Administration II (RH134), and Red Hat System Administration III: Linux Automation (RH294) to help prepare. Attendance in these classes is not required; students can choose to take just the exam.
While attending Red Hat classes can be an important part of your preparation, attending class does not guarantee success on the exam. Previous experience, practice, and native aptitude are also important determinants of success.
Many books and other resources on system administration for Red Hat products are available. Red Hat does not endorse any of these materials as preparation guides for exams. Nevertheless, you may find additional reading helpful to deepen your understanding.
