Topic 2

Configuring and Managing Continuous Integration and Continuous Delivery (CI
CD): This section tests the knowledge of CI
CD Engineers and Automation Specialists in automating the software lifecycle using OCI DevOps Service. It includes managing source code repositories, configuring build
deployment pipelines, and creating artifacts for automated deployments across environments.

Topic 3

Managing Containers Using Container Orchestration Engine: This part assesses the abilities of Kubernetes Administrators and Containerization Specialists in managing Oracle Container Engine for Kubernetes (OKE). It covers cluster creation, scaling, upgrades, networking, storage, and security configurations to optimize containerized applications in OCI environments.

Topic 4

Enabling DevSecOps: This domain measures the skills of Security Engineers and DevSecOps Practitioners in integrating security into DevOps workflows. It includes managing encryption keys with OCI Vault, securing CI
CD pipelines, and ensuring container image security to align with DevSecOps best practices.

Topic 5

Using Code and Templates for Provisioning and Configuring Infrastructure: This domain evaluates the expertise of DevOps Engineers and Infrastructure Architects in deploying infrastructure using Infrastructure as Code (IaC) tools like Terraform. It focuses on automating resource provisioning with OCI Resource Manager to ensure consistent and efficient infrastructure setups.

Oracle Cloud Infrastructure 2025 DevOps Professional Sample Questions (Q40-Q45):

NEW QUESTION # 40
While adding variables to your build_spec.yaml file, you made a mistake that resulted in a failed build pipeline.
What is the error you could have made?

A. Defined variables as exportedVariables to make them available in subsequent stages of the same pipeline
B. Used vaultVariable to hold the content of the vault secrets in Base64 format
C. Defined a field such as type: DOCKER_IMAGE in the outputArtifacts: section to specify the docker image produced by the Build stage
D. Defined parameters such as the ${VARIABLE_NAME} file and later assigned their values in the Parameters tab of the build pipeline

Answer: D

Explanation:
In build_spec.yaml for OCI DevOps, variables must be correctly defined and used according to the specification. If you defined parameters using ${VARIABLE_NAME} and then attempted to assign their values through the Parameters tab in the build pipeline, you may have introduced an error. The syntax and usage of parameters must be properly defined in both the build_spec.yaml and the build pipeline interface.

NEW QUESTION # 41
A fully qualified path to a particular image in an OCIR repository is given as iad.ocir.io/ansh81vru1zp/project01/acme-web-app:version2.0.test.
Identify the two options with correct terms and their associated values. (Choose two.)

A. ansh81vru1zp/project01/acme-web-app:version2.0.test represents <repo-name>
B. iad.ocir.io/ansh81vru1zp represents <region-key>
C. iad represents <region-key>
D. version2.0.test represents <tenancy-namespace>
E. ansh81vru1zp represents <tenancy-namespace>

Answer: C,E

Explanation:
ansh81vru1zp is the <tenancy-namespace>. In Oracle Cloud Infrastructure Registry (OCIR), the tenancy namespace uniquely identifies the tenancy and is used as part of the image path.
iad is the <region-key>. The region key is the shorthand identifier for the OCI region (iad represents Ashburn region), and it is used in the fully qualified path for images stored in the Oracle Cloud Infrastructure Registry (OCIR).

NEW QUESTION # 42
As a DevOps engineer working on a CI/CD pipeline for your company's application, you have completed code analysis, image scanning, and automated testing.
What is the next step to ensure a secure and reliable deployment?

A. Add an invoke function stage to run code or custom logic in a serverless manner.
B. Add a shell stage to run custom commands in the deployment pipeline.
C. Add an approval stage to pause the deployment for a specified duration for manual decision from the approver.
D. Add a traffic Shift stage to route the traffic between two sets ofbackend IPs.

Answer: C

Explanation:
After completing code analysis, image scanning, and automated testing, the next step in the CI/CD pipeline should include a manual review to ensure that all necessary security and quality checks have been performed correctly. Adding an approval stage helps ensure that a secure and reliable deployment is achieved by requiring human verification and approval before proceeding with the deployment to production.
This step adds an extra layer of control to prevent unintended issues from moving forward without further review. It is a common practice in CI/CD pipelines to have an approval step, especially for critical deployments.

NEW QUESTION # 43
A DevOps engineer is asked to access an Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE) cluster to deploy new applications and manage existing ones.
Which two statements are true? (Choose two.)

A. 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.
B. 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.
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. 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.
E. 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.

Answer: A,B

Explanation:
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.

NEW QUESTION # 44
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. CA bundle for Transport Layer Security (TLS) verification to download the build source during the build run is missing.
B. The Docker image used in the pipeline is incompatible with the OKE environment.
C. The OKE cluster is not configured to allow external access to the code repository.
D. Dynamic Groups and OCI IAM policies to access the code repository are missing.

Answer: D

Explanation:
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.

NEW QUESTION # 45
