Which Azure feature lets a university track and control resource costs per department?

Cost Management + Billing is the correct answer because it provides tools to analyze, manage, and optimize your Azure spending. This service allows organizations like a university to track costs by various scopes, including departments, by using features like resource tags, management groups, and cost analysis reports. Azure Monitor collects and analyzes telemetry data from your Azure resources but doesn't directly manage costs. Azure Advisor provides recommendations for optimizing performance, security, reliability, operational excellence, and cost, but it's a recommendation engine, not a cost tracking and control system itself. Azure Sentinel is a cloud-native Security Information and Event Management (SIEM) solution, focused on security, not cost management.
