Study plan
How to Pass the Oracle Cloud Infrastructure 2026 Developer Professional Exam
A study plan for the Oracle Cloud Infrastructure 2026 Developer Professional certification exam, built from the official domain weights instead of a generic template. Prioritize hands-on labs using the OCI Free Tier. Focus heavily on the interplay between OKE and CI/CD pipelines, and ensure deep familiarity with serverless execution models and IAM policy structures.
- 5 domains
- 50 questions
- 90 min
- 68% to pass

Three phases, in order
Most failures are process failures, not knowledge failures.
Phase 1 — Learn the high-weight domains
Start where the points are. The first domains on this plan carry the most weight, so a gap there costs the most. Cover the objectives, then close each topic with practice questions you actually get wrong.
Phase 2 — Close the mid-weight domains
The middle of the blueprint is where most candidates plateau. These domains are worth less per topic than the first phase, but they add up fast, and they are the usual difference between a near miss and a clear pass.
Phase 3 — Timed full mocks
Stop reading new material at this point. Run full-length exams under the real time limit and the real format, and use the per-domain breakdown to find which domain is still costing you the pass.
Where we put the emphasis
Practical implementation of automation and scalability in a cloud-native ecosystem.
The order matters less than the loop. Every domain you finish should end with questions you got wrong, because the mistake is the only thing you actually needed to study. On the Oracle Cloud Infrastructure 2026 Developer Professional that loop is worth 11% of the exam in the first block alone.
