Red Hat High Availability Clustering with Exam (RH 437)

Overview

The intensive, hands-on Red Hat High Availability Clustering (RH436) course teaches storage management, the Red Hat High Availability Add-On, and the shared storage technology delivered by Red Hat Global File System 2 (GFS2) and Red Hat Gluster Storage.

Created for senior Linux system administrators, this 4-day course strongly emphasizes lab-based activities. You'll learn how to deploy and manage shared storage and server clusters that provide highly available network services to a mission-critical enterprise environment.

This course also helps you prepare for the Red Hat Certificate of Expertise in High Availability Clustering exam (EX436). This version of the course includes the exam.

Target Audience

Senior Linux system administrators responsible for maximizing resiliency though high-availability clustering services and using fault-tolerant shared storage technologies

Prerequisites

If you want to take this course without the exam (RH436) and have not earned your RHCE certification, you can confirm that you have the necessary knowledge by passing the online skills assessment.
