When on-premises servers are onboarded to Azure Arc, Microsoft Defender for Servers can extend Microsoft Defender for Endpoint integration and server protection policies to them centrally. Enabling the Defender for Servers plan in the subscription minimizes manual effort and applies protection as Arc resources come under Defender for Cloud. Local scripts or Group Policy deployments protect current servers only and are weaker for future automatic onboarding. For SC-500, compute controls are evaluated by workload type: VM, Arc server, AKS, container registry, container group, Functions, Logic Apps, App Service, and AI agent runtime. The right answer uses the Microsoft control that is native to that workload. Broad Azure roles or unrelated monitoring services would either overgrant access or fail to enforce the required security state. The result is a direct exam-style implementation choice: it changes the required security behavior without relying on unrelated monitoring, manual cleanup, or excessive privilege.
