Schedule and Registration

Course Description

This GL254 course is designed to follow an identical set of topics as the Red Hat® RH254, RH255 RHCE exam prep courses 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 GL199 course cover the certification objects of the Red Hat Certified Engineer (RHCE) exam.

This course builds upon a foundation of core Linux systems administration principles and skills. Students will advance their Linux systems administration knowledge. The course will focus on helping students optimize system administration skills using automation techniques and deploy commonly used network services. Once this course is completed students will know how to deploy critical network services in a secure fashion.
