Microsoft Certified: Azure Fundamentals (AZ-900) Practice Exam

Using Azure Resource Manager (ARM) offers significant advantages, particularly in the area of template-driven deployment. With ARM, you can define the infrastructure and services required for your applications in a declarative manner by using JSON templates. This allows for consistent and repeatable deployments, making it easier to manage resources and ensuring that environments are set up in a standardized way.

The template-driven approach not only reduces the potential for human error during deployments but also facilitates version control and collaborative development practices. Teams can share templates, modify them as needed, and deploy complex environments simply and efficiently. This contrasts with classic deployment models where resource management and provisioning could be more manual and less systematic.

While cost efficiency, faster provisioning, and greater scalability are important factors in cloud services, they are not uniquely tied to the features that ARM provides compared to classic models. The strength of ARM lies specifically in its ability to automate deployments using templates.
