Red Hat System Administration I (RH124)

This course provides a foundation for students wishing to become full-time Linux system administrators by introducing key command line concepts and other enterprise-level tools. RH124 is designed for IT professionals without previous Linux administration experience. The course provides students with Linux administration "survival skills" by focusing on core administration tasks.

All NETLAB+ supported labs in the Red Hat System Administration I 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.

These labs are also available as an NDG Online hosted lab offering.

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.
