Designed for experienced Linux users, the course moves at a rapid pace across all RHCSA domains, helping you identify and close gaps in your systems administration skills before exam day. Topics cover every core exam domain in depth, from command-line proficiency, user administration, and security hardening to systemd service control, boot management, network configuration, storage administration, logging, scheduling, network file systems, firewalls, and container deployment. Like all Guru Labs courses, the material is designed to provide extensive hands-on experience, with 46 lab exercises on live RHEL 9 systems building the performance-based proficiency the RHCSA exam demands.
