A company deploys a .NET application to a set of Windows virtual machines. They need to automate the deployment of the application binaries and configuration files, and they want the deployment to be repeatable and idempotent. What should they use?

Azure Pipelines with a PowerShell script that uses Desired State Configuration (DSC)

A manual RDP session to copy files to each VM

A Docker container that runs the application, but without a container registry

A single Azure CLI command that runs once without any state management

A company has a release pipeline that deploys a database migration, a backend API, and a frontend app. The database migration is not idempotent and cannot be run twice. The pipeline must ensure that the migration runs only once, but the API and frontend can be deployed multiple times. What should they do?

Use a database migration task that is idempotent by design

Run the database migration in the same stage as the API and frontend, but only on the first attempt

Use a separate stage for the database migration with a condition that only runs on the first release, and use idempotent deployment tasks for the API and frontend

Run the database migration after the API and frontend deployment

A company's release pipeline deploys a new version of a database schema, then a backend API, then a frontend web app. The database migration must complete successfully before the API deployment starts, and the API must be healthy before the frontend is deployed. The team wants to avoid manual intervention. What should they configure in Azure Pipelines?

Create three stages and use the 'dependsOn' keyword on the Frontend stage to wait for both Database and API stages, with no additional checks.

Use a single stage with three jobs and job dependencies, then add a post-deployment gate on the API job.

Create three stages (Database, API, Frontend) with stage dependencies and add a post-deployment gate on the API stage that checks health before the Frontend stage runs.

Use a single stage with three sequential tasks and a delay task between each to allow time for health checks.

A company has a release pipeline that deploys a backend service and a frontend app. The backend service must be deployed and pass a health check before the frontend app is deployed. The team uses Azure Pipelines. What should they configure to enforce this dependency?

Use two jobs in the same stage and run them in parallel

Use two separate pipelines and trigger the frontend pipeline manually

Use a single job with both deployments in a single step

Use two stages: one for the backend with a health check task, and a second stage for the frontend that depends on the first stage
