Correct answer & explanation
Microsoft Purview Insider Risk Management
Microsoft Purview Insider Risk Management is the correct capability because it is specifically designed to identify, detect, and act on risky user behaviors such as unusual downloads, data leaks, and policy violations. It uses machine learning models and predefined indicators to correlate user activities (e.g., mass file downloads, unauthorized sharing) with risk signals, enabling organizations to investigate and mitigate insider threats. This aligns directly with the consultant's need to monitor and address risky behavior in a Microsoft 365 adoption plan.

Common exam traps
The trap here is that candidates often confuse Microsoft Purview Insider Risk Management with general compliance tools like Microsoft Purview Compliance Manager or DLP, but the question specifically targets risky user behavior detection, which is the unique domain of Insider Risk Management.
Detailed technical explanation
Under the hood, Microsoft Purview Insider Risk Management leverages the Microsoft 365 audit log and signals from Microsoft Defender for Cloud Apps, Azure Active Directory, and Microsoft Purview Data Loss Prevention (DLP) to build risk profiles. It uses adaptive thresholds and machine learning to detect anomalies like unusual download volumes (e.g., exceeding 100 files in an hour) or policy violations (e.g., sharing sensitive documents externally). In a real-world scenario, if a user suddenly downloads thousands of files from SharePoint to a personal device, Insider Risk Management can trigger an alert and initiate an automated investigation workflow, while other tools like Planner or Forms remain oblivious to such activity.
Key takeaway
Microsoft Purview Insider Risk Management detects risky user activities.
Real-world example
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.
