Microsoft Azure Fundamentals AZ-900 Practice Question

Azure Resource Manager (ARM) templates let you declare the desired state of an environment in a JSON file. When you submit the template to ARM, the service creates or updates the specified resources in the correct order, enabling consistent, idempotent deployments. Azure Blueprints can bundle ARM templates with additional artifacts such as policies and role assignments, but it relies on ARM templates for the actual resource creation. Azure Policy's primary purpose is governance and compliance; although certain effects like DeployIfNotExists can trigger a template deployment, it is not the tool used to author and manage infrastructure as code. Azure Automation Runbooks execute imperative scripts (PowerShell or Python) and therefore are not used for declarative template-based deployments.
