Linux Training : RHCE Rapid Track Course

This course will teach the commands and methods needed to setup and manage advanced networking, security, and performance management on a RHEL 6 system. The course will also use a problem solving approach in the lab exercises to teach system administrators advanced topics, for long-term mangement of the system.

This course is used for preparation for the RHCE certification examination.

Systems: Red Hat Enterprise Linux Version 6 (all update levels).

Linux Training Prerequisites

This course is a concentrated preparation for the RHCE examination.
