A logistics firm needs to automate deploying identical virtual machines across multiple regions. Which Azure feature should they use?

Azure Resource Manager (ARM) templates provide a declarative way to define and deploy infrastructure as code. This allows the logistics firm to define their virtual machine configuration once and then deploy identical instances consistently across multiple regions, ensuring automation and repeatability. Azure Availability Zones are for high availability within a single region, not for deploying resources across multiple regions. Azure Virtual Network peering connects virtual networks, not for deploying virtual machines. Azure Blueprints help manage compliance and governance for Azure subscriptions, but ARM templates are the direct tool for defining and deploying the infrastructure itself.
