Kubernetes Focus
- 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
- Set up event rules and practice event-driven patterns
- Understand when to use streaming vs queuing vs events
- Practice integrating multiple OCI services using Service Connector Hub
- Build scenarios that demonstrate async communication patterns
Observability
- Set up custom metrics and alarms for your applications
- Practice querying logs using Logging Analytics query language
- Implement distributed tracing with APM across microservices
- Create dashboards that visualize application health and performance
- Learn to troubleshoot common issues using observability tools
Exam-Specific Strategies
- Focus on practical scenarios - exam questions often present real-world problems
- Understand service limits, quotas, and best practices
- Know the differences between similar services and when to use each
- Practice time management - you have about 98 seconds per question
- Review the exam objectives document multiple times during preparation
- Take at least 3-4 full-length practice exams before the actual exam
Documentation Mastery
- Bookmark and organize key OCI documentation pages
- Read the 'Common Scenarios' sections in each service documentation
- Study the API reference to understand service capabilities
- Review architecture diagrams in the Architecture Center
- 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
- 6If a question involves multiple services, think about how they integrate together
