OpenShift 4.16 EX280 Mastery: Hands-On Practice & Exam Prep

Prepare to pass the Red Hat Certified Specialist in OpenShift Administration (EX280) exam with confidence. This 25-hour, end-to-end course takes you from installing and bootstrapping OpenShift 4.16 through advanced cluster operations, security hardening, application deployment, and disaster recovery. Each module combines concise theory, live CLI and web-console demos, real-world troubleshooting scenarios, and targeted practice questions. You’ll learn to:

• Deploy and bootstrap both IPI and UPI clusters in connected and air-gapped environments

• Configure OVN-Kubernetes networking, Services, and Routes for production workloads

• Integrate identity providers, craft RBAC policies, and apply SecurityContextConstraints

• Build, deploy, and automate apps with BuildConfigs, Operators, and GitOps pipelines

• Monitor with Prometheus/Grafana, aggregate logs via EFK, and perform etcd backup/restore

• Automate node management with MachineSets and MachineHealthChecks

• Execute blue/green and canary deployments, plus advanced Operator SDK development

Over 10 modules you’ll get full slide decks, spoken scripts, and built-in practice tests modeled on the EX280 blueprint. By course end, you’ll not only know the how—but also the why—behind every command, manifest, and best practice. Enroll now, tackle the 100+ practice questions, and elevate your OpenShift administration skills!

What Will Students Learn?

1. Deploy and bootstrap fully functional OpenShift 4.16 clusters using IPI and UPI in both connected and air-gapped environments.

2. Configure and manage core networking (OVN-Kubernetes, Services, Routes) and storage (CSI drivers, PVs, PVCs) in production.

3. Secure the platform by integrating LDAP/AD identity providers, defining RBAC policies, and enforcing SecurityContextConstraints.

4. Build, deploy, and automate applications with BuildConfigs, Operators, and GitOps pipelines (Argo CD/Flux), including blue/green and canary strategies.

5. Monitor, troubleshoot, and optimize clusters using Prometheus, Grafana, the EFK stack, and etcd backup/restore techniques.
