Oracle Cloud Infrastructure 2025 DevOps Professional Sample Questions (Q27-Q32):

NEW QUESTION # 27
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?

A. Managed nodes in OKE
B. Self-Managed Nodes in OKE
C. Container Instances in OCI
D. Virtual nodes in OKE

Answer: D

Explanation:
Virtual nodes in OKE provide a serverless experience for deploying Kubernetes workloads, which means you do not have to manage or scale the underlying infrastructure. This solution is particularly cost-efficient because you only pay for the resources used by the pods, and it provides strong isolation for workloads.
Virtual nodes are well suited for AI/ML workloads as they allow users to easily scale compute resources without being constrained by the limits of individual worker nodes.

NEW QUESTION # 28
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?

A. It is used to store, manage, develop source code with OCI DevOps Code Repositories.
B. It takes a commit ID from your source code repositories and uses that source code to run your build instructions.
C. It is a set of stages for your build process for building, testing and compiling software artifacts.
D. It is a sequence of steps for delivering and deploying your artifacts to a target environment.

Answer: D

Explanation:
A deployment pipeline in OCI DevOps is used to automate the deployment of application artifacts to a target environment. It is a sequence of stages that includes steps such as approvals, traffic shifts, manual interventions, and the actual deployment of the artifacts to environments like Kubernetes clusters or compute instances.

NEW QUESTION # 29
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. 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. 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.
C. 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.
D. 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.
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.

Answer: C,E

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 # 30
You are a developer and have been asked to develop an e-commerce website for your organization. It must support a variety of clients including desktop browsers, mobile browsers and native mobile applications.
Which two approaches can you use to build the application to achieve deployment independence, easier technology upgrades, and resiliency to architecture changes? (Choose two.)

A. Choose monolithic approach over microservices as it has better fault isolation capability.
B. Implement each module as an independent service/process which can be replaced, updated, or deleted without disrupting the rest of the application.
C. Use monolithic approach, as it allows you to easily redeploy your applications to perform frequent updates.
D. Use monolithic approach to as it makes it easier to incrementally adapt to newer technology.
E. Use microservices architecture as it eliminates any long-term commitment to a technology stack.

Answer: B,E

Explanation:
By implementing each module as an independent service/process (which is a core feature of microservices architecture), you can replace, update, or delete services without affecting the rest of the application. This ensures deployment independence and makes it easier to adapt to architecture changes or technology upgrades without major disruptions.
Microservices architecture allows each service to be built with the best-suited technology stack for its specific function. This flexibility ensures that you are not tied to a single technology for the entire application, making future technology upgrades easier and eliminating long-term technology commitments.

NEW QUESTION # 31
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 Production stage in the Canary deployment strategy deploys the new version to the production environment without any manual approval.
B. The Invoke Function stage is an optional stage that can be used to validate the new version before moving to the production environment.
C. The Shift Traffic stage in the Canary deployment strategy shifts the entire 100% of the production traffic to the Canary environment.
D. The Canary deployment strategy only supports pipeline redeployment for OKE and not for instance group deployments.

Answer: B

Explanation:
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.
