A project manager wants to tag Azure resources by department and environment to simplify reporting. Which feature should they use?

Resource Tags are key-value pairs that allow you to categorize Azure resources. By tagging resources with information like department and environment, you can easily filter, group, and report on costs and usage, which directly addresses the project manager's need for simplified reporting. Azure Blueprints are used for deploying and enforcing consistent sets of Azure resources and standards, not for categorization. Azure Cost Management helps analyze and manage costs, but it relies on tags or other metadata for effective filtering and reporting. Azure Policy helps enforce organizational standards and assess compliance, but it doesn't directly categorize resources for reporting purposes; it can, however, enforce the use of tags.
