質問 # 20
You host your application on a stack in Oracle Cloud Infrastructure (OCI) Resource Manager. Because of recent growth in your user base, you decide to add a CIDR block to your VCN, add a subnet, and provision a compute instance in it.
Which statement is true?
- A. You can make the changes to the Terraform code, run an Apply job, and Resource Manager will provision the new resources.
- B. You can make the changes to the Terraform code, run a Drift Detection job, and Resource Manager will provision the new resources.
- C. You need to provision a new stack because Terraform uses immutable infrastructure.
- D. You need to provision the new resources in the OCI console first, then add them later to the Terraform configuration and state.
正解：A
解説：
Oracle Cloud Infrastructure (OCI) Resource Manager uses Terraform to manage infrastructure resources. If you need to add new resources (e.g., a new CIDR block, subnet, and compute instance), you can simply make the necessary changes to the Terraform code defining the stack.
After modifying the Terraform configuration to include the new resources, you can run an Apply job in Resource Manager. The Apply job will provision the new resources in your OCI environment according to the updated Terraform code.
質問 # 21
You're using Oracle Cloud Infrastructure (OCI) DevOps to deploy your application on an Oracle Container Engine for Kubernetes (OKE) environment. You push your code to the OCI Code Repository, add all the required stage and configure the build and deployment pipeline. When you run the build, you see "unable to clone the repository" error.
What could the configuration error be?
- A. The OKE cluster is not configured to allow external access to the code repository.
- B. CA bundle for Transport Layer Security (TLS) verification to download the build source during the build run is missing.
- C. Dynamic Groups and OCI IAM policies to access the code repository are missing.
- D. The Docker image used in the pipeline is incompatible with the OKE environment.
正解：C
解説：
The error "unable to clone the repository" typically indicates that there is an authentication or authorization issue preventing access to the OCI Code Repository. In OCI DevOps, the build pipeline must have the appropriate permissions to access the code repository.
To allow the build pipeline to clone the repository, you need to set up Dynamic Groups and OCI IAM policies that provide the necessary permissions for the build runner to access the code repository.
質問 # 22
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. 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.
- B. In the build pipeline, to store the Managed Build stage outputArtifacts. you need an OCI Object storage.
- C. Once created, the artifact's name. type, and source cannot be modified.
- D. It is recommended to make artifacts immutable to prevent any modifications after they are uploaded.
正解：D
解説：
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.
質問 # 23

- A. To access the cluster using kubectl, you have to set up a Kubernetes manifest file for the cluster. The kubeconfig file by default is named config and stored in the $HOME/.manifest directory.
- B. When a cluster's Kubernetes API endpoint has a public IP address, you can access the cluster in Cloud Shell by setting up a kubeconfig file.
- C. Generating an API signing key pair is not required while setting up cluster access using local machine if the public key is not already uploaded in the console.
- D. The only available option when a cluster's Kubernetes API endpoint has a public IP address is to control the cluster locally using kubectl and the Kubernetes Dashboard.
- E. To access the cluster using kubectl, you have to set up a Kubernetes configuration file for the cluster. The kubeconfig file by default is named config and stored in the $HOME/.kube directory.
正解：B、E
解説：
To access an OKE cluster using kubectl, you need to set up a Kubernetes configuration file (kubeconfig). By default, the kubeconfig file is named config and stored in the $HOME/.kube directory.
When a cluster's Kubernetes API endpoint has a public IP address, you can use Cloud Shell to access the cluster. Setting up a kubeconfig file is required to authenticate and manage the cluster.
質問 # 25
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. Deliver artifacts
- C. Managed build
- D. Export packages
正解：B
解説：
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

A DevOps team is deploying a new version of their application to their production environment using the Canary deployment strategy in the OCI DevOps service. They want to ensure that the production environment is not affected by any potential issues caused by the new version.
Which statement is true in regards to the Canary deployment strategy?
- A. The Canary deployment strategy only supports pipeline redeployment for OKE and not for instance group deployments.
- B. The Production stage in the Canary deployment strategy deploys the new version to the production environment without any manual approval.
- C. The Invoke Function stage is an optional stage that can be used to validate the new version before moving to the production environment.
- D. The Shift Traffic stage in the Canary deployment strategy shifts the entire 100% of the production traffic to the Canary environment.
正解：C
解説：
In a Canary deployment strategy, a new version of an application is rolled out to a small subset of the production environment (the canary) first, while the majority of the production environment still runs the current stable version. This approach helps to detect potential issues before the new version is fully deployed.
The Invoke Function stage can be used as an optional step in the deployment pipeline to run additional validation (e.g., automated tests or other checks) on the new version before gradually shifting more traffic to it or moving to full production deployment.
