Course Description

Course Overview

Red Hat High Availability Clustering (RH436) is an advanced course designed for system administrators and IT professionals seeking to gain expertise in deploying, configuring, and managing high availability clusters using Red Hat Enterprise Linux. This course covers essential topics related to high availability clustering, including cluster management, failover, resource management, and troubleshooting. Participants will learn how to design and implement high availability solutions to ensure the continuous availability of critical services and applications.

Prerequisites

• Proficiency in Linux system administration concepts and tasks.
• Familiarity with basic networking concepts and services.
• Prior experience with Red Hat Enterprise Linux (RHEL) is recommended.

Methodology

The RH436 course follows a blended learning approach, combining theoretical lectures, practical demonstrations, and hands-on lab exercises. Instructors will provide comprehensive explanations of high availability clustering concepts and features, followed by practical demonstrations to illustrate their implementation. The majority of the course will focus on hands-on lab exercises, allowing participants to gain real-world experience in deploying and managing high availability clusters using RHEL.
