About

The EX280 validates hands-on ability to deploy, configure, and manage Red Hat OpenShift clusters in production environments. Launched in 2021 with OpenShift 4.x, it is a Professional-level credential that proves core competency in container platform administration—cluster installation, operator management, networking, persistent storage, RBAC, and troubleshooting. The exam is entirely performance-based: candidates provision and configure a real OpenShift cluster under time pressure. Prerequisite knowledge of RHCSA is strongly recommended. EX280 sits between RHCSA (Associate, single-host Linux) and EX380 (Expert, DevOps CI/CD) in Red Hat's certification stack, positioning OpenShift Administrators and Container Platform Engineers.

Domain context — Container/PaaS

Container platform administration: deploying, scaling, and maintaining Kubernetes-based PaaS systems. OpenShift abstracts Kubernetes complexity with integrated tooling, authentication, storage, networking, and operators, enabling enterprises to run containerized workloads at scale.

Topics covered

Based on Red Hat's official EX280 exam blueprint:

• Cluster installation and bootstrap — Deploy OpenShift using IPI (Installer Provisioned Infrastructure) and UPI (User Provisioned Infrastructure); customize cluster config (compute profiles, network ranges); manage cluster operators
• Cluster operators and add-ons — Understand Operator Framework; manage built-in operators (DNS, ingress, monitoring); add third-party operators (certified on OperatorHub)
• Cluster networking — Configure Routes and Ingress; manage network policies; understand Service types (ClusterIP, NodePort, LoadBalancer); DNS and certificate management
• Persistent storage — Create and manage PersistentVolumes (PV) and PersistentVolumeClaims (PVC); configure storage classes; manage StatefulSets; integrate with NFS, iSCSI, and cloud storage backends
• Authentication and authorization — Configure identity providers (LDAP, OAuth); manage RBAC roles and bindings; audit access logs; manage service accounts
• Logging and monitoring — Deploy and configure ELK stack (Elasticsearch, Logstash, Kibana) via Operators; Prometheus and Grafana monitoring; alerting rules; cluster event logging
• Application deployment and updates — Deploy containerized workloads using Deployments, StatefulSets, DaemonSets; manage ConfigMaps and Secrets; perform rolling updates and rollbacks; pod disruption budgets
• Pod scheduling and resource management — Resource requests/limits; quality-of-service (QoS) tiers; node affinity and taints/tolerations; pod priority and preemption
• Cluster troubleshooting — Debug pod failures; diagnose networking issues; verify operator health; recover from cluster component failures; analyze logs and metrics
