Important Oracle 1Z0-1109-25 Exam Questions

Answer: B

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.

Answer: C

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.

Answer: D

Explanation:

Oracle Cloud Infrastructure (OCI) Resource Manager uses Terraform to manage infrastructure resources. If you need to add new resources (e.g., a new CIDR block, subnet, and compute instance), you can simply make the necessary changes to the Terraform code defining the stack.

After modifying the Terraform configuration to include the new resources, you can run an Apply job in Resource Manager. The Apply job will provision the new resources in your OCI environment according to the updated Terraform code.

Answer: C

Explanation:

Step 1: Understanding the Requirement

The objective is to store the resulting build output from a Build Pipeline in a container repository. In OCI DevOps, the build output is stored as an artifact, which can include Docker images or other build-generated files. To store these artifacts in a container repository, you need to explicitly deliver artifacts in the pipeline.

Step 2: Explanation of the Options

A . Trigger deployment

This stage is used to trigger a deployment pipeline, which comes after the artifacts are already stored and prepared for deployment.

Not applicable: This stage is downstream of storing artifacts and is used for deploying software, not for saving the build output to a repository.

B . Managed build

The managed build stage is where you compile, test, and package the application. This has already been completed successfully according to the question.

Not applicable: The question specifies that the build has been completed, so this stage is not relevant at this point.

C . Deliver artifacts

The Deliver Artifacts stage in OCI DevOps pipelines is designed to store the output of the build process in an artifact repository, such as:

OCI Container Registry (OCIR) for Docker images.

Artifact Registry for build artifacts like binaries or JAR files.

Applicable and Correct Answer: This is the correct next step for storing the resulting

D . Export packages

This is not a standard OCI DevOps pipeline stage. It may be relevant in other contexts but is not related to OCI DevOps for storing build artifacts.

Step 3: Key Concepts of 'Deliver Artifacts' in OCI DevOps

Purpose: Save build outputs (artifacts) to an artifact repository.

Artifact Types: Includes Docker container images, binaries, JAR files, or other build outputs.

Repositories Supported:

OCI Container Registry (OCIR)

OCI Artifact Registry

Configuration:

Specify the artifact source (build stage output).

Define the destination repository (e.g., OCIR).

Answer: B, C

Explanation:

You need the required permissions (such as policies allowing secret management) to create and manage secrets in Oracle Cloud Infrastructure (OCI) Vault service. These permissions are essential for performing operations such as creating, reading, and managing secrets.

Vault managed key is required to encrypt the secret before it is stored in the OCI Vault. The managed key acts as the encryption key for securing the secret, ensuring its confidentiality.
