Diagnose, troubleshoot, and resolve issues in Red Hat Enterprise Linux systems.

The Red Hat Enterprise Linux Diagnostics and Troubleshooting (RH342) course equips senior system administrators with advanced skills to identify, analyze, and resolve system problems efficiently.
Through extensive hands-on labs, participants learn structured troubleshooting techniques for a variety of common issues across system subsystems, including boot failures, hardware problems, storage management, RPM package errors, network issues, security incidents, and kernel-level faults.

The course emphasizes applying the scientific method to troubleshooting—formulating hypotheses, testing systematically, and isolating root causes—to ensure consistent, repeatable success in diagnosing issues.

This course is based on Red Hat Enterprise Linux 8.4.
