Red Hat System Administration I (RHEL9) [RH124]

OVERVIEW

The first of two courses covering the core system administration tasks needed to manage Red Hat Enterprise Linux servers

Red Hat System Administration I (RH124) is designed for IT professionals without previous Linux system administration experience.
