Oracle Cloud Infrastructure 2025 DevOps Professional Sample Questions (Q35-Q40):

NEW QUESTION # 35
As a DevOps engineer at XYZ Corp, you are responsible for ensuring the smooth operation of high-traffic web applications hosted on Oracle Cloud Infrastructure (OCI). The web applications run on multiple OCI resources, including virtual machines, load balancers, and databases. Recently, users have reported failures while accessing one of the OCI-based web applications, and you suspect HTTP 5XX errors on the load balancer. You need to quickly identify and address this issue.
Which of the following statements can assist you in quickly identifying and monitoring the HTTP 5XX error rate on the load balancer and setting up notifications?

A. Use Metrics and Alarms of the Monitoring service to monitor the HTTP 5XX error rate on the load balancer and set up notifications with OCI Notifications.
B. Use Metrics and Alarms of the Monitoring service with Container Engine for Kubernetes (OKE) to monitor HTTP 5XX errors on Kubernetes resources and correlate them with other OCI resources.
C. Use Custom Metrics of the Monitoring service to collect HTTP 5XX error rates from the load balancer and set up Service Connectors with third-party services such as PagerDuty or Slack.
D. Use Event Rules to detect HTTP 5XX errors on the load balancer and trigger automated actions using OCI Functions or API Gateway.

Answer: B

Explanation:
The Monitoring service in OCI can be used to track metrics for various OCI resources, including load balancers. You can monitor specific metrics, such as HTTP 5XX error rates, to identify issues.
By using Alarms, you can set up thresholds for the HTTP 5XX error rate and receive notifications when the threshold is breached. The notifications can be configured through OCI Notifications, which allows integration with email, PagerDuty, Slack, and other channels.

NEW QUESTION # 36
As a DevOps engineer working on containerizing a microservices-based application to be hosted on OCI Cloud platforms, which step can help ensure that the container images have not been modified after being pushed to Oracle Cloud Infrastructure Registry (OCIR)?

A. Signing the image using the Container Registry CLI and creating an image signature that associates the image with the master encryption key and key version in the Vault service
B. Enabling scanning of container images stored in OCI Registry
C. Scanning the image upon ingestion and comparing the image size for changes
D. Deploying a manifest to the Kubernetes cluster that references the container image and its unique hash

Answer: A

Explanation:
To ensure that container images have not been modified after being pushed to the Oracle Cloud Infrastructure Registry (OCIR), you should sign the image. This involves using the Container Registry CLI to create a digital signature for the image, which associates the image with a master encryption key and key version stored in the OCI Vault service. This signature can then be verified at the time of deployment, ensuring that the image has not been tampered with since it was signed.

NEW QUESTION # 37
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?

A. Access to an Oracle Cloud Infrastructure tenancy is required to set up the new OKE cluster.
B. Container Engine for Kubernetes cannot utilize existing network resources for the creation of the new cluster.
C. Container Engine for Kubernetes automatically creates and configures new network resources for the new cluster.
D. It is necessary to ensure sufficient quota on different resource types in your OCI tenancy for the cluster setup.

Answer: B

Explanation:
This statement is false because Container Engine for Kubernetes (OKE) can utilize existing network resources such as Virtual Cloud Networks (VCNs), subnets, security lists, and route tables for the creation of a new cluster. You can either use pre-existing network resources or let OKE create new network resources automatically.

NEW QUESTION # 38
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 takes a commit ID from your source code repositories and uses that source code to run your build instructions.
B. It is a set of stages for your build process for building, testing and compiling software artifacts.
C. It is a sequence of steps for delivering and deploying your artifacts to a target environment.
D. It is used to store, manage, develop source code with OCI DevOps Code Repositories.

Answer: C

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 # 39
Which statement is false about OCI Resource Manager (RM)?

A. RM can mirror repositories from GitHub and GitLab.
B. RM can generate Terraform based on the resources in a compartment.
C. RM can render custom "Application Information" pages for stacks.
D. Resources provisioned through RM cannot be destroyed from outside of RM.

Answer: D

Explanation:
Resources provisioned through OCI Resource Manager (RM) can still be modified or destroyed from outside of RM, such as using the OCI Console, CLI, or other APIs. RM manages the lifecycle of resources created by its Terraform configurations, but it does not prevent other tools or methods from modifying or deleting those resources.
