A later version of these labs is available. We recommend that you use Red Hat System Administration III (RH294-RHEL8) when starting a new class.

Red Hat System Administration III (RH254)

This course, designed for experienced Linux system administrators who have completed RH124 and RH134, allows learners to broaden their ability to administer Linux systems at an enterprise level.

All NETLAB+ supported labs in the Red Hat System Administration III course are supported using the Red Hat System Admin pod.

Participation in the Red Hat® Academy program is required. Participating NETLAB+ customers may contact NDG to request enabled Red Hat content.

Using the Labs

Always select the correct lab exercise for the lab being performed. Students or teams should schedule the correct lab exercise from the catalog. NETLAB+ will only show those labs for which the required pod type is available. A lab that works on different pod types may appear more than once if your system is so equipped. Instructors should select the correct lab from the Exercise tab during instructor-led lab reservations. This can be done as many times as needed during the reservation.
