OCI 1Z0-1109-25 Study Plan: 30, 60, and 90 Days

OCI 1Z0-1109-25 30-, 60-, and 90-day study plan with topic order, review loops, and final-week priorities.

This plan is built around the DevOps loop: deliver -> observe -> recover -> improve.

How to use this plan well

Each study block should do four things:

  1. classify the issue as source, build, deploy, IaC, verify, or rollback
  2. decide which OCI control belongs there
  3. do a short scenario set
  4. write down whether the miss was stage choice, release safety, or observability weakness

	  Classify["Classify source / build / deploy / verify / rollback"] --> Control["Choose OCI control"]
	  Control --> Drill["Do short scenario set"]
	  Drill --> Review["Review why misses happened"]
	  Review --> Classify

How long should you study?

Typical candidates need 70 to 120 focused hours.

Your time Recommended timeline Good fit
18 to 22 hrs/week 30 days intensive path with some delivery experience
10 to 14 hrs/week 60 days balanced path for most candidates
6 to 9 hrs/week 90 days part-time path with slower reinforcement

30-day intensive plan

Week Focus Output
1 environments, IAM, secrets, governance, and source-to-build flow stage notes and short drills
2 CI/CD pipelines, artifacts, gates, and release discipline rollout tie-break sheet
3 IaC, Resource Manager, Terraform state, and deployment strategies weak-lane notes and mixed sets
4 observability, incident response, rollback, and final readiness mixed sets and compression

60-day balanced plan

Phase Weeks Focus
1 1 to 2 terminology cleanup and delivery-stage classification
2 3 to 4 source, build, artifacts, gates, and release safety
3 5 to 6 IaC, Resource Manager, Terraform state, and environment boundaries
4 7 monitoring, logging, verification, and rollback triggers
5 8 weak-lane repair and mixed review

90-day part-time plan

Month Focus Goal
1 DevOps vocabulary and delivery-loop basics stop losing points to stage confusion
2 release strategy, IaC safety, and secrets or least privilege build stronger safe-delivery judgment
3 observability, recovery, and exam-style tie-breaks finish with mixed-set confidence

If misses cluster here, do this next

Miss pattern Weak lane Fix next
you choose the wrong rollout pattern release strategy review canary, blue-green, rolling, and rollback trade-offs
you ignore state or environment boundaries IaC review Resource Manager, Terraform state, and scope separation
you ship but do not verify effectively observability review metrics, logs, alarms, dashboards, and release verification
you automate but cannot recover safely rollback and ops review known-good restore logic and incident response

What strong prep usually does

  • classifies the delivery stage first, then picks the OCI control
  • keeps a short confusion list for build vs deploy, rollback vs redeploy, and monitoring vs logging
  • writes down why the winning answer is safer or more repeatable instead of just memorizing it
  • uses Oracle docs to settle disagreements, then comes back here for compression

Final 72 hours

Keep doing Stop doing
rereading the cheat sheet and glossary opening unrelated new CI/CD or IaC tools
reviewing weak-lane misses treating DevOps as only build automation
checking official docs for disputed boundaries building a large late-stage delivery platform
practicing source -> build -> deploy -> verify -> rollback order trusting unsupported community summaries over Oracle docs
