Your organization has Microsoft Defender for Cloud Apps (MDA) connected to Microsoft Sentinel. The SOC team wants to receive alerts when a user accesses a sanctioned cloud app from an anonymous IP address. What should you configure?
Activity policies can detect specific behaviors like anonymous IP access and send alerts to Sentinel.
Why this answer
An activity policy in Defender for Cloud Apps can be configured to trigger alerts on specific user activities, such as accessing a sanctioned app from an anonymous IP address. This policy can then be connected to Microsoft Sentinel via the Defender for Cloud Apps data connector, which ingests alerts as incidents for SOC review. File policies (A) focus on file-level actions like sharing or malware detection, not user access events, while session policies (D) control real-time access but do not generate alerts for historical or post-access monitoring.
Exam trap
The trap here is that candidates confuse file policies with activity policies, assuming any policy in Defender for Cloud Apps can detect access events, but only activity policies are designed to monitor user sign-in and access behaviors against IP-based conditions.
How to eliminate wrong answers
Option A is wrong because file policies monitor file-related activities (e.g., sharing, upload, download) and cannot detect user access events like logging into an app from an anonymous IP. Option C is wrong because simply enabling the Defender for Cloud Apps connector in Sentinel without additional configuration only ingests default alerts (e.g., from anomaly detection policies), not custom activity-based alerts for anonymous IP access. Option D is wrong because session policies are designed for real-time access control and monitoring during a user session (e.g., blocking downloads), not for generating alerts on access events that have already occurred.
