Access to an Oracle Cloud Infrastructure tenancy is required to set up the new OKE cluster.

QUESTION 29
As a developer working on a software project to be deployed on OKE, you have created a Helm chart for your application. You want to deploy the chart using OCI DevOps service.
Which statement is true about deploying a Helm Chart using OCI DevOps service?

A single chart can be installed only once into the same cluster, and create single release.

The Helm charts must be located in the OCI Container Registry repository for deployment.

The values.yaml file is a generic file located in the OCI Container Registry. You must create a reference to this file.

Oracle Cloud Infrastructure (OCI) DevOps service supports deployment of Helm charts to Container Instances.

QUESTION 30
How can system administrators ensure that only signed images from Oracle Cloud Infrastructure Registry are deployed to a Container Engine for Kubernetes cluster?

By disabling access to the Container Engine for Kubernetes cluster

By manually inspecting each image before deployment

By encrypting the images using a custom encryption algorithm

By configuring an image verification policy for the cluster

QUESTION 31
In Kubernetes clusters created by Container Engine for Kubernetes, how is data in etcd encrypted at rest by default?

Using encryption keys managed by Oracle using a master encryption key

Encryption using TLS certificates

No encryption applied

Using encryption keys managed by the user

QUESTION 32
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 33
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 34
Which command creates the docker registry secret required in the application manifests for OKE to pull images from Oracle Cloud Infrastructure Registry?

QUESTION 35
You’re using Oracle Cloud Infrastructure (OCI) DevOps service to automate your software releases to release features more frequently and with fewer errors. While deploying an update to production, one of your deployment stages failed.
What action should you perform in your Deployment Pipeline?

Use OCI DevOps Trigger and Rerun tool to avoid downtime.

Automate back up and use the rerelease stage in the Deployment Pipeline.

Add Rescue and Trigger stages to automatically trigger the failed deployment.

Roll back the failed stage in the pipeline to the previous successful released version

QUESTION 36
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 37
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?

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.

In the build pipeline, to store the Managed Build stage outputArtifacts. you need an OCI Object storage.

It is recommended to make artifacts immutable to prevent any modifications after they are uploaded.

Once created, the artifact’s name. type, and source cannot be modified.

QUESTION 38
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 39
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?

You need to provision a new stack because Terraform uses immutable infrastructure.

You can make the changes to the Terraform code, run a Drift Detection job, and Resource Manager will provision the new resources.

You need to provision the new resources in the OCI console first, then add them later to the Terraform configuration and state.

You can make the changes to the Terraform code, run an Apply job, and Resource Manager will provision the new resources.
