A DevOps engineer needs to deploy multiple Azure resources consistently across test and production environments. Which approach should they use?

Azure Resource Manager (ARM) templates provide a declarative way to define and deploy Azure resources. By using ARM templates, the DevOps engineer can ensure consistency because the same template can be used to deploy identical resource configurations across both test and production environments. This eliminates manual configuration errors and promotes infrastructure as code. Azure Bastion provides secure RDP/SSH connectivity to virtual machines, but it doesn't automate resource deployment. Azure Security Center offers unified security management and threat protection, which is not directly related to consistent resource deployment. Azure Policy helps enforce organizational standards and assess compliance, but it doesn't deploy resources itself; it governs existing or new deployments.
