A logistics company wants to enforce tagging on all deployed resources. What should they implement?

Azure Policy is the correct choice because it allows you to create, assign, and manage policies that enforce rules and effects over your resources to ensure compliance with corporate standards and service level agreements. In this scenario, a policy can be defined to require specific tags on all new or existing resources, preventing deployment if the tags are missing or incorrect. Azure Resource Manager is the deployment and management service for Azure, but it doesn't enforce policies directly. Azure Cost Management helps analyze and manage cloud spending, not resource tagging enforcement. Azure Monitor collects and analyzes telemetry data from Azure resources, which is unrelated to enforcing tagging standards.
