Pass the Oracle Oracle Cloud Infrastructure 1z0-1109-24 Questions and answers with CertsForce

After completing code analysis, image scanning, and automated testing, the next step in the CI/CD pipeline should include a manual review to ensure that all necessary security and quality checks have been performed correctly. Adding an approval stage helps ensure that a secure and reliable deployment is achieved by requiring human verification and approval before proceeding with the deployment to production.

This step adds an extra layer of control to prevent unintended issues from moving forward without further review. It is a common practice in CI/CD pipelines to have an approval step, especially for critical deployments.

For critical applications, such as the one used by the finance department, a blue-green deployment strategy is recommended to ensure minimal or zero downtime during upgrades. The blue-green strategy involves running two separate environments: blue (current version) and green (new version).

When a deployment stage fails in a OCI DevOps Deployment Pipeline, the recommended approach is to roll back to the previous successful version to ensure that the production environment remains in a stable state. This approach minimizes disruption and ensures that your system continues to function properly while the issue with the failed deployment is investigated and fixed.

Oracle Cloud Infrastructure Functions is a serverless compute service that supports a consumption-based pricing model. This means that you are only charged for the compute resources when your function is invoked. This is ideal for intermittent, dynamic, and irregular workloads since the company does not need to provision infrastructure in advance, and costs are directly tied to usage.

To create a Docker registry secret to pull images from the Oracle Cloud Infrastructure Registry (OCIR), you need to specify the correct parameters such as the region key, namespace, OCI username, and OCI authentication token.

Chosen command is correct because:

The kubectl create secret docker-registry command creates a Docker registry secret.

The --docker-server=.ocir.io specifies the correct endpoint for OCIR.

The --docker-username=/ provides both the tenancy namespace and the OCI username, which is the required format for authentication with OCIR.

The --docker-password='' specifies the OCI auth token, which acts as a password for authentication.

The --docker-email= is also included.

The other commands have errors, such as missing tenancy namespace or using incorrect flags (passwd instead of secret).

To access an OKE cluster usingkubectl, you need to set up a Kubernetes configuration file (kubeconfig). By default, the kubeconfig file is namedconfigand stored in the$HOME/.kubedirectory.

When a cluster’s Kubernetes API endpoint has apublic IP address, you can useCloud Shellto access the cluster. Setting up a kubeconfig file is required to authenticate and manage the cluster.

OCI DevOps Deployment Pipelines automate the process of deploying applications to production environments. By using automated, repeatable deployment processes, they help reduce the risk of change-driven errors, which are often introduced during manual deployments. This automation reduces human errors and ensures consistency across environments, thus minimizing complexity and risk in production.

By implementing each module as anindependent service/process(which is a core feature ofmicroservices architecture), you can replace, update, or delete services without affecting the rest of the application. This ensuresdeployment independenceand makes it easier to adapt toarchitecture changesor technology upgrades without major disruptions.

Microservices architectureallows each service to be built with the best-suited technology stack for its specific function. Thisflexibilityensures that you are not tied to a single technology for the entire application, making future technology upgrades easier and eliminatinglong-term technology commitments.

In OCI DevOps Build Pipeline, the output artifacts generated during the build are temporary and will be discarded unless explicitly stored in a persistent location. By extracting and storing these artifacts in an Artifact Registry (such as OCI Artifact Registry or OCI Container Registry), you ensure that they are available for subsequent stages, such as deployment.

Storing artifacts in a registry provides a persistent location where the deployment pipeline can access them, ensuring the artifacts are available for reliable deployment.

Step 1: Understanding the Requirement

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

Step 2: Explanation of the Options

A. Trigger deployment

This stage is used to trigger adeployment 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 youcompile, 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

TheDeliver Artifactsstage in OCI DevOps pipelines is designed tostore the output of the build process in an artifact repository, such as:

OCI Container Registry (OCIR)for Docker images.

Artifact Registryfor build artifacts like binaries or JAR files.

Applicable and Correct Answer: This is the correct next step for storing the resulting output of a build pipeline.

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).
