Correct answer & explanation
✓
Anomaly detection policy
An anomaly detection policy in Defender for Cloud Apps can identify unusual file download activities based on predefined thresholds. Option A is wrong because a file policy monitors files based on metadata or content, not behavioral patterns. Option C is wrong because an app permission policy governs permissions granted to third-party apps. Option D is wrong because a session policy enforces real-time controls on user sessions.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Your company uses Microsoft Defender for Cloud Apps. You notice that a user is downloading large volumes of data from a sanctioned cloud app that exceeds the normal pattern. Which action should you take to automatically block this activity?
hard- ✓ A.Create a session policy to monitor and control downloads
- B.Configure a cloud discovery policy
- C.Create a Microsoft Purview DLP policy
- D.Block the app in Defender for Cloud Apps
Why A: You can create a session policy in Microsoft Defender for Cloud Apps that monitors user behavior and can block or restrict downloads that exceed a predefined threshold. Option B is wrong because a cloud discovery policy is used to discover shadow IT, not to block downloads. Option C is wrong because Microsoft Purview DLP policies are for data loss prevention based on content classification, not for blocking based on volume of downloads. Option D is wrong because blocking the entire app is too restrictive; a session policy allows targeted action on specific risky activities.
