SC-200 Respond to security incidents Practice Question
Your organization uses Microsoft Defender for Cloud Apps. An alert indicates that a user is downloading large amounts of data from SharePoint Online. What should you do first to investigate?
⚠ Common exam trap
Many exam-takers confuse immediate governance actions (like suspending or blocking) with the proper investigative first step, failing to recognize that Defender for Cloud Apps requires log review to confirm the alert's validity before applying any automated or manual response.

Correct answer & explanation
✓
Review the user's activity log in Defender for Cloud Apps.
The first step in investigating a potential data exfiltration alert is to review the user's activity log in Defender for Cloud Apps. This log provides granular details about the specific files downloaded, the volume of data, the time frame, and the source IP address, allowing you to validate whether the activity is anomalous or legitimate before taking any restrictive action.
