Your company has multiple business units. Each business unit needs 20 identical Azure resources for daily operations. You must recommend a way to automate creating these Azure resources. What should you recommend?

Azure Resource Manager (ARM) templates are the correct choice because they enable Infrastructure as Code (IaC). You can define the desired state of your Azure resources in a JSON file, including their configuration and dependencies. This template can then be deployed repeatedly to create identical sets of resources across different business units efficiently and consistently, ensuring automation and reducing manual errors. Virtual machine scale sets are designed for deploying and managing a group of identical, auto-scaling virtual machines, not for deploying 20 diverse resources for each business unit. The Azure API Management service is used for publishing, securing, and managing APIs, not for automating resource creation. Management groups are used for organizing subscriptions and applying governance policies at scale, not for deploying resources.
