EX280 Exam Preparation

EX280 is the most popular OpenShift certification. Here's a detailed preparation strategy.

Exam Scope Details

1. Manage OpenShift Clusters

• Understand cluster installation (no actual installation required)
• Use Web Console and oc CLI
• Check cluster health status

2. Configure Authentication and Authorization

• Configure HTPasswd identity provider
• Create users and groups
• Configure RBAC roles and bindings

3. Configure Networking

• Create and manage Routes
• Configure Network Policies
• Manage TLS certificates

4. Configure Pod Scheduling

• Use Node Selector and Node Affinity
• Use Taints and Tolerations
• Configure resource quotas and limits

5. Configure Cluster Scaling

• MachineSet management
• Manual cluster scaling

Preparation Strategy

1. Complete Official Course DO280

If budget allows, this is the most effective approach. The course covers all exam topics and includes hands-on practice.

2. Practice Extensively

The exam is purely hands-on with no multiple choice questions. Practice until you can "type commands without thinking."

Key practice items:

# Authentication configuration
oc create secret generic htpass-secret --from-file=htpasswd=... -n openshift-config
oc apply -f oauth.yaml

# RBAC configuration
oc adm policy add-role-to-user admin user1 -n project1
oc adm policy add-cluster-role-to-user cluster-admin user1

# Route configuration
oc create route edge --service=my-svc --hostname=my-app.example.com

# Network Policy
oc apply -f network-policy.yaml

# Resource quota
oc create quota my-quota --hard=cpu=4,memory=8Gi -n project1

3. Familiarize with Official Documentation

You can reference documentation during the exam. Familiarize yourself with the documentation structure beforehand and know where to find answers.

4. Time Management

3 hours for approximately 15-20 questions, averaging 10 minutes per question. Some questions are quick, some need more time. Skip questions you're stuck on.

Exam Tips

1. Verify Environment

• First verify cluster access
• Note down cluster URL and login information

2. Use Tab Completion

# Enable completion first
source <(oc completion bash)

3. Use --dry-run

# Verify command correctness before executing
oc create deployment my-app --image=nginx --dry-run=client -o yaml

4. Use oc explain

# View resource field explanations
oc explain deployment.spec

5. Verify Results Verify results after each question to confirm it actually worked.

FAQ

Q1: Can I learn OpenShift directly without Kubernetes basics?

You can, but it will be harder. Many OpenShift concepts come from Kubernetes, so learning OpenShift directly will lead to many "what is this" questions. We recommend spending at least one week understanding K8s basics like Pod, Deployment, Service, etc.

Q2: Is EX280 difficult? What's the pass rate?

Red Hat doesn't publish pass rates, but according to community discussions, people who prepare well have good pass rates. The difficulty lies in: (1) Pure hands-on, no multiple choice; (2) Time is a bit tight; (3) Need to be proficient with commands. Practice until you can "type commands without thinking."

Q3: How long is certification valid?

Red Hat certifications are valid for 3 years. After expiration, you need to retake or pass a higher-level certification to extend. Certification validity is also tied to OpenShift versions—certifications on older versions may need updating.

Q4: Is self-study or official courses better?

Depends on your learning style and budget. Official courses are systematic, have lab environments, and quality is guaranteed, but expensive. Self-study saves money and is flexible, but you need to find resources and environments yourself. If your company will pay, official courses are worth it; with limited budget, self-study + Developer Sandbox works.

Q5: Can the exam be taken in Chinese?

The exam interface can be set to Chinese, but commands and documentation are in English. We recommend using the English interface because translations are sometimes awkward, and you'll use English commands at work anyway.
