The correct answer is a custom detection rule in Microsoft Defender XDR that includes an incident assignment action. This is because Microsoft Defender XDR’s advanced hunting and custom detection capabilities allow you to create rules that not only detect specific campaign activity but also automatically assign the resulting incident to a designated SOC group through the “Assign incident” action within the rule. On the SC-200 exam, this question tests your understanding of the distinction between Defender XDR’s native automation tools and those of Microsoft Sentinel—a common trap is confusing custom detection rules with Sentinel’s automation rules, which only apply to Sentinel incidents, not Defender XDR incidents. Remember that custom detection rules are built from KQL queries in the advanced hunting section, while standard Microsoft Defender for Endpoint rules lack assignment functionality. A helpful memory tip: “Custom detection assigns; automation rules are for Sentinel only.”

Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
