Oracle Cloud Infrastructure 2025 DevOps Professional Sample Questions (Q30-Q35):

NEW QUESTION # 30
An operations team is exploring the use of OCI Container Instances to run their container workloads without managing servers.
Which of the following statements is false regarding the use of Container Instances?

A. The underlying infrastructure for Container Instances is fully managed and hardened by OCI, ensuring reliability and security.
B. Billing for Container Instances is based on the allocated CPU and memory resources for each container instance.
C. Container Instances provide a serverless compute service for running containers, eliminating the need for server management.
D. Container Instances require the team to perform provisioning, patching, and ongoing management of servers.

Answer: D

Explanation:
OCI Container Instances are a serverless compute service that allows you to run containerized workloads without managing the underlying infrastructure. Oracle Cloud Infrastructure (OCI) manages provisioning, patching, and all the ongoing server management tasks, providing a fully managed environment.

NEW QUESTION # 31
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. Deploying a manifest to the Kubernetes cluster that references the container image and its unique hash
B. 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
C. Scanning the image upon ingestion and comparing the image size for changes
D. Enabling scanning of container images stored in OCI Registry

Answer: B

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 # 32
How does the Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE) Cluster Autoscaler determine when to create new nodes for an OKE cluster?

A. When the resource requests from pods exceed a configured threshold.
B. When the custom metrics from the services exceed a configured threshold.
C. When the rate of requests to the application crosses a configured threshold.
D. When the CPU or memory utilization crosses a configured threshold.

Answer: A

Explanation:
The OKE Cluster Autoscaler automatically adjusts the number of worker nodes in an OKE cluster based on the resource requests made by Kubernetes pods. When there are not enough resources available (e.g., CPU or memory) on existing nodes to accommodate pending pods, the Cluster Autoscaler will create new nodes to meet the resource demand.

NEW QUESTION # 33
Which OCI DevOps project resource is responsible for defining the stages for compiling, testing, and running software applications before deployment?

A. Deployment pipelines
B. Build pipelines
C. Development pipelines
D. Integration pipelines

Answer: B

Explanation:
Build pipelines in OCI DevOps are responsible for defining the stages involved in compiling, testing, and running software applications. These pipelines automate the process of building the code, running unit tests, scanning for vulnerabilities, and packaging the software, all of which occur before deploying the application.

NEW QUESTION # 34
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.)

A. Using Application Dependency Management (ADM) to identify security weaknesses in software applications by checking their dependencies
B. Using version control tools like Git or SVN to track and manage changes in the codebase
C. Using third-party tools like Ansible, Terraform, or OverOps to analyze code for security defects or bugs in code quality
D. Using JIRA to track user stories and bug fixes in the development process
E. Using third-party tools like Sonatype, SonarQube, or OverOps to analyze code for security defects or bugs in code quality

Answer: A,E
