Oracle Cloud Infrastructure DevOps Professional Exam Practice Test

The Oracle Cloud Infrastructure DevOps Professional Exam practice page focuses on delivery workflows in OCI: building and deploying software, provisioning infrastructure through code, and operating pipeline-connected applications. The question bank includes scenarios about diagnosing pipeline failures, protecting changes before infrastructure deployment, managing build access to private resources, and improving visibility into application logs and release artifacts.

About the Oracle Cloud Infrastructure DevOps Professional Exam

DevOps work in OCI involves coordinating source-controlled configuration, build steps, deployment targets, and operational feedback. The practice scenarios ask you to distinguish pipeline stages and their failure information, define ordered build commands, and use stored configuration files in pipeline stages. They also address delivery decisions such as limiting network exposure when builds need private-subnet access and using infrastructure as code to make provisioning repeatable and reviewable. Other questions connect operations and software supply-chain controls: centralizing logs and metrics, inspecting artifact contents, reducing dependency risk before packaging, and interpreting change lead time as a delivery-performance measure. These tasks require matching a stated engineering need to an appropriate control or OCI capability rather than recalling an isolated service name.

Sample Practice Questions

Review a selection from this exam's published US Practice Tests practice bank.

Question 1

A team is investigating why a pipeline run failed and needs to identify which stage reported the failure. Which information should they inspect first?

  1. AThe pipeline run's stage execution status and stage logs
  2. BThe subnet's route table rules
  3. CThe application's DNS time-to-live
  4. DThe repository's branch protection label
Show answerCorrect answer: A

A pipeline run exposes the status and execution details of its stages. Stage-level status and logs are the direct starting point for locating a pipeline failure.

Question 2

A team wants to prevent an accidental destructive change from being applied through an infrastructure-as-code workflow. Which practice most directly helps catch the change before it is applied?

  1. AReview and validate the proposed plan before applying it
  2. BIncrease the application's log retention period
  3. CAdd more compute capacity to the deployment environment
  4. DDisable version control for the configuration
Show answerCorrect answer: A

Inspecting and validating a proposed infrastructure plan before applying it helps identify unintended changes while they are still reviewable. Logging and capacity changes do not provide this safeguard.

Question 3

A build must access a private subnet resource, but the build environment should not be exposed directly to the public internet. Which design consideration is most relevant?

  1. AConfigure the build environment's network access to use an appropriate VCN and subnet
  2. BAdd the subnet CIDR to the artifact version string
  3. CPublish the build logs to a public bucket
  4. DUse a deployment approval stage instead of network configuration
Show answerCorrect answer: A

When a build needs private network access, its network configuration must provide connectivity to the required VCN resources while preserving the intended network boundaries.

Question 4

A team needs to retain logs and metrics from an application running on OCI compute instances so operators can review them centrally. Which OCI capability is the best starting point?

  1. AOCI Logging and Monitoring services
  2. BOCI DNS zones
  3. COCI Object Storage lifecycle policies
  4. DOCI File Storage snapshots
Show answerCorrect answer: A

OCI Logging provides centralized collection and querying of logs, while OCI Monitoring supports metrics and alarms. Together they are suitable foundations for operational visibility.

Question 5

A team needs to keep a reusable deployment configuration file under version control and make it available to OCI DevOps pipeline stages. Which OCI DevOps resource is designed to store and serve such files?

  1. AA DevOps artifact
  2. BA service connector
  3. CA virtual cloud network
  4. DA metrics alarm
Show answerCorrect answer: A

OCI DevOps artifacts can represent files or references used by pipeline stages, including deployment configuration inputs. The other options are unrelated infrastructure or monitoring resources.

Question 6

An organization wants to reduce the risk that a compromised build process silently introduces an unexpected executable into a release. Which control most directly improves visibility into the artifact's contents?

  1. AGenerate and review a software bill of materials for the release
  2. BIncrease the number of deployment regions
  3. CUse a shorter application version string
  4. DDisable all build notifications
Show answerCorrect answer: A

A software bill of materials (SBOM) records components included in a software artifact, improving transparency and supporting review of unexpected dependencies or components. The other options do not provide an inventory of artifact contents.

Question 7

A team wants to run a command-line validation script as part of an OCI DevOps build. Where should it define the build steps and their execution order?

  1. AIn a build specification file
  2. BIn a deployment environment definition
  3. CIn a vault secret bundle
  4. DIn a notification subscription
Show answerCorrect answer: A

A build specification describes build phases and the commands or actions to run, including validation scripts, in a defined sequence.

How to use this practice test

Access is free. A session presents up to 20 randomly selected questions from the 50-question practice bank, then shows your results. Use the scenarios to identify gaps in pipeline troubleshooting, infrastructure change review, private-network build design, observability, and artifact or dependency controls.

Preparation tips

  • For pipeline troubleshooting, map each stage to its logs and status information, then practice locating the first reported failure before investigating downstream effects.
  • Review how build specifications define command steps and execution order, and how reusable configuration files are stored for pipeline use.
  • Sketch a build that must reach a private OCI resource; identify the network path and access controls without exposing the build environment directly to the public internet.
  • Compare pre-apply infrastructure review, artifact-content inspection, and dependency-risk checks; note which risk each control is intended to catch.
  • Distinguish application logs and metrics used for operational review from delivery metrics such as lead time for changes.
