OCI 1Z0-1109-25 Sample Questions with Explanations

These original sample questions are designed to help you check how the exam topics appear in decision-style prompts. They are not taken from the live exam.

Use these sample questions as a guided self-assessment for OCI DevOps Professional (1Z0-1109-25) topics such as build and deployment pipelines, artifacts, infrastructure as code, Resource Manager, rollout strategy, rollback planning, secrets, logs, metrics, and post-deploy verification. The prompts focus on delivery-loop judgment rather than tool-name recall.

1Z0-1109-25 OCI DevOps sample questions

Work through each prompt before opening the explanation. DevOps questions usually ask where a control belongs in the loop: source, build, artifact, deploy, verify, rollback, infrastructure, or observability.

Question 1

Topic: Build-stage validation

A pipeline deploys an application even when unit tests fail. Operations only notices after users report errors. Which improvement belongs earliest in the delivery flow?

• A. Add a larger production instance shape so failed code has more resources.
• B. Ask operators to watch dashboards more closely after every release.
• C. Add a build or validation gate that stops artifact promotion and deployment when tests fail.
• D. Disable test output so the pipeline log is easier to read.

Best answer: C

Explanation: Failed tests should stop the change before it becomes a deployable artifact or reaches production. A validation gate in the build stage makes the pipeline enforce quality before deployment.

Why the other choices are weaker:

• A treats bad code as a capacity issue.
• B detects harm later instead of stopping the release.
• D removes evidence and weakens troubleshooting.

What this tests: Pipeline stages, validation gates, artifact promotion, and release safety.

Question 2

Topic: Canary rollout

A team is releasing a risky service change. They want to expose the new version to a small slice of traffic, watch error and latency metrics, and stop rollout automatically if signals degrade. Which release strategy best fits?

• A. Canary deployment with clear health metrics, progressive promotion, and rollback criteria.
• B. Direct all production traffic to the new version immediately.
• C. Delete the old version before testing the new one so there is no confusion.
• D. Skip monitoring because canary deployments are safe by definition.

Best answer: A

Explanation: Canary rollout reduces early blast radius by exposing a small portion of traffic first. It only works well when paired with health metrics, promotion rules, and rollback criteria.

Why the other choices are weaker:

• B maximizes exposure before evidence.
• C removes the known-good rollback target.
• D ignores the signal path that makes canary useful.

What this tests: Canary deployment, blast-radius reduction, metrics, promotion gates, and rollback planning.

Question 3

Topic: Infrastructure drift

A Terraform-managed environment has been edited manually in the console several times. The next planned infrastructure change shows unexpected differences. What is the strongest response?

• A. Continue making console edits because they are faster than reviewing code.
• B. Delete the state file and recreate it from memory.
• C. Give every engineer administrator permissions so drift is easier to fix.
• D. Investigate drift using plan/state evidence, reconcile the desired configuration in version control, and apply reviewed infrastructure changes through the IaC workflow.

Best answer: D

Explanation: Drift should be brought back into a reviewed, version-controlled infrastructure workflow. The plan and state evidence show what changed, and the corrected configuration should become the source of truth.

Why the other choices are weaker:

• A perpetuates drift.
• B risks losing the mapping between managed resources and configuration.
• C increases risk and does not restore repeatability.

What this tests: Infrastructure as code, state, drift, reviewed changes, and repeatable environments.

Question 4

Topic: Secret handling in pipelines

A deployment pipeline needs a database credential during release. The credential currently appears in the build log and repository history. What is the strongest remediation?

• A. Rename the credential variable so it is harder to search for.
• B. Move the secret into an approved secrets-management service or protected pipeline secret store, rotate the exposed credential, and restrict access to the minimum required scope.
• C. Keep the credential in source control but add a comment telling developers not to share it.
• D. Turn off all pipeline logging permanently.

Best answer: B

Explanation: The exposed credential should be treated as compromised and rotated. Future use should come from a managed secret path with access controls and masking, not repository history or logs.

Why the other choices are weaker:

• A does not remove exposure.
• C keeps the secret compromised.
• D removes useful operational evidence and does not solve secret storage.

What this tests: Secrets management, rotation, pipeline security, least privilege, and audit-safe delivery.
