Oracle Cloud Infrastructure 2025 DevOps Professional Sample Questions (Q31-Q36):

NEW QUESTION # 31
As a DevOps engineer working with OCI DevOps, you are managing artifacts for a microservices application.
Based on your understanding of working with DevOps projects and artifacts, which statement is true?

A. In the build pipeline, to store the Managed Build stage outputArtifacts. you need an OCI Object storage.
B. Artifacts can be used directly by OCI DevOps without the need for them to be located or mirrored in an OCI Artifact or Container registry.
C. It is recommended to make artifacts immutable to prevent any modifications after they are uploaded.
D. Once created, the artifact's name. type, and source cannot be modified.

Answer: C

Explanation:
Making artifacts immutable ensures that the build artifacts are not altered after being published. This is a best practice to maintain the integrity and consistency of the artifacts used in deployments, preventing unintentional changes that could introduce issues during subsequent deployment stages.

NEW QUESTION # 32
You are a developer and have been asked to develop an e-commerce website for your organization. It must support a variety of clients including desktop browsers, mobile browsers and native mobile applications.
Which two approaches can you use to build the application to achieve deployment independence, easier technology upgrades, and resiliency to architecture changes? (Choose two.)

A. Implement each module as an independent service/process which can be replaced, updated, or deleted without disrupting the rest of the application.
B. Choose monolithic approach over microservices as it has better fault isolation capability.
C. Use microservices architecture as it eliminates any long-term commitment to a technology stack.
D. Use monolithic approach, as it allows you to easily redeploy your applications to perform frequent updates.
E. Use monolithic approach to as it makes it easier to incrementally adapt to newer technology.

Answer: A,C

Explanation:
By implementing each module as an independent service/process (which is a core feature of microservices architecture), you can replace, update, or delete services without affecting the rest of the application. This ensures deployment independence and makes it easier to adapt to architecture changes or technology upgrades without major disruptions.
Microservices architecture allows each service to be built with the best-suited technology stack for its specific function. This flexibility ensures that you are not tied to a single technology for the entire application, making future technology upgrades easier and eliminating long-term technology commitments.

NEW QUESTION # 33
How does the Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE) Cluster Autoscaler determine when to create new nodes for an OKE cluster?

A. When the custom metrics from the services exceed a configured threshold.
B. When the rate of requests to the application crosses a configured threshold.
C. When the resource requests from pods exceed a configured threshold.
D. When the CPU or memory utilization crosses a configured threshold.

Answer: C

Explanation:
The OKE Cluster Autoscaler automatically adjusts the number of worker nodes in an OKE cluster based on the resource requests made by Kubernetes pods. When there are not enough resources available (e.g., CPU or memory) on existing nodes to accommodate pending pods, the Cluster Autoscaler will create new nodes to meet the resource demand.

NEW QUESTION # 34
What is the correct approach to upgrade an Oracle Container Engine for Kubernetes (OKE) Cluster to a newer version of Kubernetes?

A. Upgrade the node pools one at a time, then once all node pools are upgraded, upgrade the control plane.
B. Initiate the control plane and node pool upgrades simultaneously.
C. Initiate the automated upgrade process using the OCI Console, CLI, or API.
D. Upgrade the control plane, then upgrade the node pools.

Answer: D

Explanation:
The correct approach to upgrade an Oracle Container Engine for Kubernetes (OKE) cluster involves first upgrading the Kubernetes control plane, followed by upgrading the node pools. The control plane must be upgraded first to ensure compatibility with newer versions of Kubernetes, as node pools rely on the control plane for orchestration and management.
After upgrading the control plane, each node pool is upgraded to match the new Kubernetes version. This phased approach ensures the cluster remains in a stable state during the upgrade.

NEW QUESTION # 35
You are using the Oracle Cloud Infrastructure (OCI) DevOps service and you have successfully built and tested your software applications in your Build Pipeline. The resulting output needs to be stored in a container repository.
Which stage should you add next to your Build Pipeline?

A. Trigger deployment
B. Export packages
C. Deliver artifacts
D. Managed build

Answer: C

Explanation:
Step 1: Understanding the Requirement
The objective is to store the resulting build output from a Build Pipeline in a container repository. In OCI DevOps, the build output is stored as an artifact, which can include Docker images or other build-generated files. To store these artifacts in a container repository, you need to explicitly deliver artifacts in the pipeline.
Step 2: Explanation of the Options
A . Trigger deployment
This stage is used to trigger a deployment pipeline, which comes after the artifacts are already stored and prepared for deployment.
Not applicable: This stage is downstream of storing artifacts and is used for deploying software, not for saving the build output to a repository.
B . Managed build
The managed build stage is where you compile, test, and package the application. This has already been completed successfully according to the question.
Not applicable: The question specifies that the build has been completed, so this stage is not relevant at this point.
C . Deliver artifacts
The Deliver Artifacts stage in OCI DevOps pipelines is designed to store the output of the build process in an artifact repository, such as:
OCI Container Registry (OCIR) for Docker images.
Artifact Registry for build artifacts like binaries or JAR files.
Applicable and Correct Answer: This is the correct next step for storing the resulting D . Export packages This is not a standard OCI DevOps pipeline stage. It may be relevant in other contexts but is not related to OCI DevOps for storing build artifacts.
Step 3: Key Concepts of "Deliver Artifacts" in OCI DevOps
Purpose: Save build outputs (artifacts) to an artifact repository.
Artifact Types: Includes Docker container images, binaries, JAR files, or other build outputs.
Repositories Supported:
OCI Container Registry (OCIR)
OCI Artifact Registry
Configuration:
Specify the artifact source (build stage output).
Define the destination repository (e.g., OCIR).
Step 4: References and OCI Resources
OCI DevOps Build Pipelines:
Build Pipeline Documentation
Deliver Artifacts Stage
