Red Hat System Administration II RHEL7


Course Description

This course will present the commands and methods needed to setup and manage a RHEL 7 system. The course will also use a problem-solving approach in the lab exercises to teach system administrators advanced topics, for long-term management of the system. This course normally requires five (5) days, approximately 50% lecture, and 50% hands-on commands and lab exercises. If this class is being used as a preparation for the RHCSA examination, a practice exam will be part of the afternoon on the fifth day.

This course is the equivalent to Red Hat course 134 and is a continuation and companion to Red Hat course 124 and is the second preparation course for the RHCSA 7 certification examination.

Systems: Red Hat Enterprise Linux Version 7 (all update levels)
