QUESTION 27
As a cloud engineer, you are responsible for managing a Kubernetes cluster on the Oracle Cloud Infrastructure (OCI) platform for your organization. You are looking for ways to ensure reliable operations of Kubernetes at scale while minimizing the operational overhead of managing the worker node infrastructure.
Which cluster option is the best fit for your requirement?

Using OCI OKE managed nodes with cluster autoscalers to eliminate worker node infrastructure management

Using OCI OKE virtual nodes to eliminate worker node infrastructure management

Using Kubernetes cluster add-ons to automate worker node management

Creating and managing worker nodes using OCI compute instances

QUESTION 28
As a DevOps engineer at XYZ Corp, you have been assigned the task of setting up a new OKE (Oracle Kubernetes Engine) cluster to manage the organization’s Kubernetes applications hosted on Oracle Cloud Infrastructure (OCI). Your goal is to ensure a smooth and efficient process while preparing for the cluster creation.
Which of the following statements is false regarding the preparation process for setting up a new OKE cluster?

Container Engine for Kubernetes cannot utilize existing network resources for the creation of the new cluster.

Container Engine for Kubernetes automatically creates and configures new network resources for the new cluster.

It is necessary to ensure sufficient quota on different resource types in your OCI tenancy for the cluster setup.

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.

QUESTION 40
As an engineer building and deploying applications using an OCI DevOps project, which two capabilities can help ensure the security and reliability of the code in the build and deployment pipelines? (Choose two.)

Using Application Dependency Management (ADM) to identify security weaknesses in software applications by checking their dependencies

Using third-party tools like Sonatype, SonarQube, or OverOps to analyze code for security defects or bugs in code quality

Using JIRA to track user stories and bug fixes in the development process

Using version control tools like Git or SVN to track and manage changes in the codebase

Using third-party tools like Ansible, Terraform, or OverOps to analyze code for security defects or bugs in code quality

QUESTION 41
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?

The Production stage in the Canary deployment strategy deploys the new version to the production environment without any manual approval.

The Canary deployment strategy only supports pipeline redeployment for OKE and not for instance group deployments.

The Invoke Function stage is an optional stage that can be used to validate the new version before moving to the production environment.

The Shift Traffic stage in the Canary deployment strategy shifts the entire 100% of the production traffic to the Canary environment.

QUESTION 42
