Course Description

Course Overview

Red Hat OpenShift Enterprise Administration II (DO280) is an advanced course designed for experienced system administrators and application developers who want to further enhance their skills in managing and troubleshooting Red Hat OpenShift Container Platform. This course focuses on advanced administration topics, including configuring advanced networking, security, storage, and monitoring features. Participants will also gain expertise in troubleshooting and optimizing OpenShift deployments for enterprise-level container orchestration.

Prerequisites

• Successful completion of Red Hat OpenShift Enterprise Administration I (DO280) or equivalent knowledge and experience.
• Proficiency in Linux system administration and container technology concepts.
• Familiarity with Red Hat OpenShift Container Platform and Kubernetes administration.

Methodology

The DO280 course follows a blended learning approach, combining theoretical lectures, practical demonstrations, and hands-on lab exercises. Instructors will deliver comprehensive explanations of advanced OpenShift concepts, followed by demonstrations to illustrate practical implementations. The majority of the course will be devoted to hands-on lab exercises, allowing participants to apply their knowledge in real-world scenarios. Real-world use cases and troubleshooting scenarios will be used to demonstrate the application of learned concepts in enterprise-level OpenShift deployments.
