Course Description

Course Overview

Red Hat System Administration III (RH254) is an advanced-level course designed to expand the knowledge and skills of experienced Linux system administrators. This course focuses on advanced system administration tasks in Red Hat Enterprise Linux, including configuring network services, security measures, web services, virtualization, and more. Through hands-on lab exercises, practical demonstrations, and real-world scenarios, students will gain the expertise required to manage and secure complex enterprise Linux environments.

Prerequisites

• Successful completion of Red Hat System Administration I (RH124) and Red Hat System Administration II (RH134) or equivalent knowledge and experience.
• Proficiency in fundamental Linux system administration tasks and concepts.

Methodology

The RH254 course follows an interactive and hands-on learning approach. Instructors will deliver theoretical lectures and practical demonstrations to cover advanced concepts in Red Hat Enterprise Linux. The majority of the course will be dedicated to hands-on lab exercises, allowing students to apply their knowledge in real-world scenarios. This practical experience is crucial for gaining the skills needed for enterprise-level Linux administration.
