Red Hat Enterprise Performance Tuning (RH442)

Course Description:

  The Red Hat Enterprise Performance Tuning (RH442) course is a 5-day course that was designed to help experienced Linux administrators learn more about Red Hat Enterprise Linux 8.

This course reviews the tasks covered in Red Hat System Administration I (RH124) and Red Hat System Administration II (RH134) at an accelerated pace. On completion of course materials, students should be prepared to take the Red Hat Certified System Administrator (RHCSA) exam.

Note: This course builds on a student's existing understanding of command-line based Linux system administration. Students should be able to execute common commands using the shell, work with common command options, and access man pages for help. Students lacking this knowledge are strongly encouraged to take Red Hat System Administration I (RH124) and Red Hat System Administration II (RH134) instead.

Topics covered in the course include:

• Managing users and groups, files, and file permissions
• Updating software packages with yum
• Managing and troubleshooting systemd services during the boot process
• Network configuration and basic troubleshooting
• Managing local storage and creating and using file systems
• Firewall management with firewalld
• Managing Kernel-based Virtual Machines (KVMs)
• Automating installation of Red Hat Enterprise Linux using Kickstart

Target Student: This course is ideal for:

• Students preparing to take the Red Hat Certified System Administrator (RHCSA) exam
