What deployment benefit do ARM templates provide?

ARM (Azure Resource Manager) templates are declarative templates that define the infrastructure and configuration for your Azure solutions. Their primary benefit is being repeatable and idempotent. Repeatable means you can deploy the same template multiple times to achieve the same desired state, ensuring consistency across environments. Idempotent means that applying the template multiple times will produce the same result as applying it once; it won't create duplicate resources or cause unintended side effects. This makes them ideal for automation and Infrastructure as Code (IaC) practices. "One-time use only" is incorrect because ARM templates are designed for repeated deployments. "Inconsistent between regions" is incorrect; ARM templates help ensure consistency across regions by defining the same resources. "Manual configuration required" is incorrect as ARM templates automate resource deployment, reducing the need for manual steps.
