GL134 - Red Hat Enterprise Linux Systems Admin II

This GL134 course is designed to follow an identical set of topics as the Red Hat® RH134 course with the added benefit of very comprehensive lab exercises and detailed lecture material.

The Red Hat Enterprise Linux (RHEL) system administration topics covered in this course along with the GL124 course cover the certification objects of the Red Hat Certified System Administrator (RHCSA) exam.

The topics covered include automating installation with Kickstart, intermediate and advanced level command line building blocks and tools, troubleshooting, network file sharing server configuration, connecting to a directory service, managing advanced security settings, maintenance tasks, and kernel tuning.
