Hands-On Practice Strategy
- Spend at least 50% of study time on hands-on practice in OCI console
- Create a personal DevOps project repository to demonstrate all concepts
- Build at least 3 complete CI/CD pipelines with different deployment strategies
- Practice writing build_spec.yaml and deployment_spec.yaml from memory
- Use OCI Free Tier extensively - it provides enough resources for full practice
- Document your lab work with architecture diagrams and decision rationale
Exam Domain Focus
- Allocate study time proportional to exam weights: CI/CD (30%), IaC (25%), Architecture (25%), Monitoring (20%)
- The CI/CD domain is largest - build multiple real pipelines with different strategies
- Understand the relationship between all DevOps components (projects, repositories, build pipelines, artifacts, deployments)
- Know IAM policies required for each DevOps service and component
- Study deployment strategies deeply: blue-green vs canary vs rolling - when to use each
Infrastructure as Code Mastery
- Practice writing Terraform configurations without looking at documentation
- Understand Resource Manager stack lifecycle: plan, apply, destroy, drift detection
- Know how to manage Terraform state in OCI Object Storage
- Learn OCI provider-specific resources and data sources
- Practice using variables, outputs, and modules in Terraform
- Understand how to trigger automation with OCI Events and Functions
Monitoring and Optimization
- Create custom metrics for your DevOps pipelines during practice
- Understand query syntax for Logging Analytics
- Know how Service Connector Hub routes logs between services
- Practice creating alarms with different severity thresholds
- Understand cost optimization strategies: compute autoscaling, right-sizing, Always Free resources
- Learn security best practices for DevOps: Vault for secrets, audit logging, IAM policies
Exam Preparation Tactics
- Review the official OCI documentation the week before exam - it's the single source of truth
- Create flashcards for service limits, quotas, and key configuration parameters
- Practice time management: 90 minutes for 55 questions = 1.6 minutes per question
- Mark questions you're unsure about and review them at the end
- Focus on scenario-based questions - understand WHY a solution works, not just HOW
- Review your hands-on lab notes before the exam - recall of practical experience helps
Common Pitfalls to Avoid
- Don't confuse OCI DevOps service with external CI/CD tools like Jenkins or GitLab
- Understand the difference between OCIR (Oracle Cloud Infrastructure Registry) and external registries
- Know when to use Functions vs Kubernetes vs Compute instances for deployments
- Don't overlook IAM policies - many exam scenarios involve access control
- Remember that deployment strategies have different use cases and trade-offs
- Pay attention to regional vs global services and multi-region architectures
Exam Day Tips
- 1Arrive 15 minutes early if testing at a center; test your equipment 30 minutes early for online proctoring
- 2Read each question carefully - Oracle exams often have subtle wording that changes the correct answer
- 3Eliminate obviously wrong answers first, then choose between remaining options
- 4Watch for keywords like 'MOST secure', 'MOST cost-effective', 'LEAST operational overhead'
- 5For scenario-based questions, identify the core requirement before evaluating options
- 6Don't spend more than 2 minutes on any single question - flag and return if needed
- 7You need 68% to pass (38 out of 55 questions) - don't panic if some questions seem difficult
- 8Trust your hands-on experience - practical knowledge often helps eliminate incorrect options
- 9Review all flagged questions before submitting - you may have learned context from later questions
- 10If you're unsure between two answers, go with your first instinct unless you find clear evidence otherwise
