- Understand Kubernetes objects thoroughly: Pods, Services, Deployments, ConfigMaps, Secrets
- Practice writing YAML manifests from scratch without templates
- Learn kubectl commands for troubleshooting and debugging
- Understand networking in Kubernetes including ingress controllers
- Practice rolling updates, rollbacks, and different deployment strategies
DevOps and CI/CD
- Create complete CI/CD pipelines using OCI DevOps for different scenarios
- Practice writing build specifications and deployment manifests
- Understand blue-green and canary deployment strategies
- Learn Terraform basics and create OCI resources using IaC
- Practice with OCI Resource Manager and understand state management
Messaging and Integration
- Create applications that produce and consume from OCI Streaming

- Keep a personal cheat sheet of important concepts and commands
Exam Day Tips
- 1Arrive 15 minutes early (or log in early for online proctoring) to handle any technical issues
- 2Read each question carefully - watch for keywords like 'NOT', 'LEAST', 'EXCEPT'
- 3For scenario-based questions, identify the key requirements first before looking at options
- 4Mark difficult questions for review and move on - don't spend too much time on any single question
- 5Use the process of elimination for questions where you're unsure
