Overview of the Red Hat Certified OpenShift Administrator Exam
The EX280 certification validates the expertise of cluster administrators and cloud engineers in managing Red Hat OpenShift Container Platform environments. Candidates must demonstrate proficiency in configuring and managing high-availability control planes, worker nodes, and integrated registries while implementing robust role-based access control and network policies. Mastery of Kubernetes-native primitives, cluster monitoring via Prometheus and Grafana, and persistent storage management using CSI drivers is critical. The exam assesses operational competencies in automated scaling, log aggregation, and troubleshooting node conditions. Successful practitioners execute complex cluster upgrades, manage ingress controllers with HAProxy, and secure containerized workloads through strict security context constraints and ImageStreams.
