GL299 - RHCE Rapid Track Course

This course is carefully designed to match the topics found in the Red Hat® RH299 exam prep course but also features the added benefit of an entire extra day of comprehensive lab exercises and detailed lecture material.

Students learn the Red Hat Enterprise Linux (RHEL) system administration skills needed to pass the Red Hat Certified Engineer (RHCE) exam. This is an accelerated course meant for those students capable of absorbing information at a rapid pace or those students who only need to fill in selected gaps of knowledge because of prior Linux sys-admin experience.
