Which Azure feature lets an organization classify resources by department, environment, and cost center?

Resource Tags are key-value pairs that allow you to categorize Azure resources. This classification is crucial for organizing resources by criteria like department, environment (e.g., production, development), and cost center. Tags enable efficient resource management, cost reporting, and policy enforcement. Management Groups are used for managing access, policy, and compliance across multiple subscriptions, not for classifying individual resources. Azure Roles define permissions for users or groups to perform specific actions on resources. Azure Blueprints help define repeatable sets of Azure resources that implement standards, patterns, and requirements, but they don't classify existing resources.
