   A DevOps team uses Terraform to manage infrastructure across AWS and Azure. They want to provision an F5 BIG-IP virtual edition in Azure using a deployment template that is invoked from their existing Terraform configuration. The BIG-IP deployment must be created only when a specific Terraform variable is set to true. How should the team integrate the template with Terraform?

   • AUse the azurerm_template_deployment resource in Terraform, guarded by a count or for_each condition based on the variable.
   • BUse Terraform's local-exec provisioner to run an Azure CLI command that deploys the template.
   • CConvert the ARM template to a Terraform configuration and manage all resources natively in Terraform.
   • DRun the ARM template deployment as a separate step in the CI/CD pipeline before Terraform runs.

   A team has deployed a web application using an ARM template. They now need to remove the entire deployment, including all associated resources, when the application is decommissioned. What is the most efficient way to achieve this?

   • AUse the Azure CLI to delete the template deployment, which removes all resources.
   • BRun the template with a 'delete' mode to remove the resources.
   • CManually delete each resource from the Azure portal.
   • DDelete the resource group that contains all the deployed resources.

   A large enterprise uses a CI/CD pipeline to deploy a microservices application to Azure. Each service is defined in its own ARM template. The team wants to deploy all services in a specific order, with the database service first, then the backend services, and finally the frontend services. They also need to pass the output of the database deployment (e.g., connection string) to the backend deployments. What is the most effective approach?

   • ACombine all resources into a single template and use dependsOn to order them.
   • BDeploy each template separately in the pipeline, hardcoding the connection string in the backend templates.
   • CUse linked templates with dependencies and pass outputs between them.
   • DUse a script that deploys the templates in order and retrieves the outputs using Azure CLI.

   How do deployment templates integrate with cloud orchestration platforms?

   • ATemplates are standalone files that cannot be executed by any external tool; they must be manually uploaded to the cloud console.
   • BTemplates replace orchestration platforms entirely, so no integration is needed.
   • COrchestration platforms can invoke templates as part of a larger automated workflow, such as a CI/CD pipeline.
   • DOrchestration platforms convert templates into virtual machine images before deployment.

   A company has a production application deployed via an ARM template. They need to increase the number of VM instances in the deployment from 2 to 5 to handle increased load. They want to make this change without recreating the entire deployment. What should they do?

   • ADelete the existing deployment and create a new one with the updated instance count.
   • BManually add three new VMs in the Azure portal and connect them to the existing load balancer.
   • CModify the instance count parameter in the template and redeploy the same template with the new parameter value.
   • DCreate a new ARM template that only contains the three additional VMs and deploy it separately.
