QUESTION 16
You’re using Oracle Cloud Infrastructure (OCI) DevOps to automate your application deployment for frequent releases. In one of your automation steps, you’ll create a deployment pipeline.
What does this deployment pipeline do in OCI DevOps?

It takes a commit ID from your source code repositories and uses that source code to run your build instructions.

It is a sequence of steps for delivering and deploying your artifacts to a target environment.

It is used to store, manage, develop source code with OCI DevOps Code Repositories.

It is a set of stages for your build process for building, testing and compiling software artifacts.

QUESTION 17
An operations team wants to leverage the advanced features of Container Engine for Kubernetes (OKE) and requires granular control over cluster add-ons, workload identity, and improved worker node management. They also prioritize strong security measures and require a financially-backed service level agreement (SLA) for Kubernetes API server uptime.
Which type of cluster should they choose to meet their requirements?

Enhanced clusters

Federated clusters

Virtual clusters

Specialized clusters

QUESTION 18
Which is NOT a valid log category for the Oracle Cloud Infrastructure Logging service?

Custom Logs

Audit Logs

Service Logs

Execution Logs

QUESTION 19
As a DevOps engineer working on an OCI project, you’re setting up a deployment pipeline to automate your application deployments.
Which statement is false about deployment pipeline in OCI DevOps?

Using deployment pipeline, you can deploy helm charts in OCI Function.

You can add a Wait stage that adds a specified duration of delay in the pipeline.

You can add a Traffic Shift stage that routes the traffic between two environments.

You can add an Approval stage that pauses the deployment for a specified duration for manual decision from the approver.

QUESTION 20
Which OCI DevOps project resource is responsible for defining the stages for compiling, testing, and running software applications before deployment?

Deployment pipelines

Build pipelines

Development pipelines

Integration pipelines

QUESTION 21
How can you scale a deployment named nodejs-deployment to have two replicas?

kubectl set replicas deployment nodejs-deployment –replicas=2

kubectl resize deployment nodejs-deployment –replicas=2

kubectl adjust deployment nodejs-deployment –replicas=2

kubectl scale deployment nodejs-deployment –replicas=2

QUESTION 22
How can you run applications on GPU worker nodes in clusters created using Container Engine for Kubernetes (OKE)?

By selecting a managed node pool, a GPU shape, and a GPU image, and ensuring that the CUDA libraries for different GPUs are pre-installed on the worker nodes

By selecting a virtual node pool, a GPU shape, and a GPU image, and ensuring that the CUDA libraries are included in the application container

By selecting a managed node pool, a GPU shape, and a GPU image that has CUDA libraries pre-installed, and specifying the number of GPU resources required in the pod spec

By selecting a managed node pool, a GPU shape, and a GPU image, and specifying the number of CPU resources required in the pod spec

QUESTION 23
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?

Defined parameters such as the ${VARIABLE_NAME} file and later assigned their values in the Parameters tab of the build pipeline

Defined variables as exportedVariables to make them available in subsequent stages of the same pipeline

Defined a field such as type: DOCKER_IMAGE in the outputArtifacts: section to specify the docker image produced by the Build stage

Used vaultVariable to hold the content of the vault secrets in Base64 format

QUESTION 24
A team wants to deploy artificial intelligence and machine learning workloads in their OCI Container Engine for Kubernetes (OKE) cluster. They prioritize strong isolation, cost-efficiency, and the ability to leverage serverless capabilities.
Which solution is best suited for their requirements?

Virtual nodes in OKE

Self-Managed Nodes in OKE

Managed nodes in OKE

Container Instances in OCI

QUESTION 25
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.)

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.

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.

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.

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.

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.

QUESTION 26
Which of the following statement is INCORRECT with respect to a Dockerfile?

WORKDIR instruction sets the working directory for any RUN, CMD, ENTRYPOINT instructions and not for COPY and ADD instructions in the Dockerfile.

An ENV instruction sets the environment value to the key, and it is available for the subsequent build steps and in the running container as well.

The RUN instruction will execute any commands in a new layer on top of the current image and commit the results.

If CMD instruction provides default arguments for the ENTRYPOINT instruction, both should be specified in JSON format.

QUESTION 27
Why is it important to extract output artifacts from the Oracle Cloud Infrastructure (OCI) DevOps build pipeline and store them in an Artifact Registry repository?

All artifacts are permanently stored in the build pipeline. Extracting just the ones required for deployment tells the deployment pipeline which artifacts to use.

Storing build artifacts in registries helps the deployment pipeline differentiate output artifacts created by the build pipeline from artifacts copied from a Git repository.

Deliver Artifacts is a required stage of the build pipeline, and the entire pipeline won’t work if it is not included in order to extract artifacts after the Managed Build stage.

Output artifacts aren’t permanent. If they are to be used in the Deliver Artifacts stage, they need to be exported as output artifacts to a registry.

QUESTION 28
Which statement is false about OCI Resource Manager (RM)?

Resources provisioned through RM cannot be destroyed from outside of RM.

RM can render custom “Application Information” pages for stacks.

RM can generate Terraform based on the resources in a compartment.

RM can mirror repositories from GitHub and GitLab.

QUESTION 29
How does the Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE) Cluster Autoscaler determine when to create new nodes for an OKE cluster?

When the CPU or memory utilization crosses a configured threshold.

When the resource requests from pods exceed a configured threshold.

When the custom metrics from the services exceed a configured threshold.

When the rate of requests to the application crosses a configured threshold.

QUESTION 30
You are a DevOps engineer working on a project that requires you to push and pull Docker images to and from Oracle Cloud Infrastructure Registry (Container Registry) using Docker CLI. You have been given access to Container Registry and have installed Docker CLI on your local machine.
Which should you create and use to securely authenticate and store your Docker image in a private Docker registry in OCI?

Auth Token

JSON Web Token

SSH Key Pair

Master Encryption Key in OCI Vault
