Overview of the EX280 Exam

The Red Hat Certified Specialist in OpenShift Administration (EX280) is a performance-based certification exam designed to validate your ability to manage, configure, and troubleshoot OpenShift clusters in real-world environments.

This exam is closely aligned with the DO280 course (Red Hat OpenShift Administration II), which focuses on production cluster configuration, security, networking, and operator management.

Unlike theoretical exams, EX280 tests candidates in a hands-on lab environment, where they must perform tasks directly on a live OpenShift cluster.
