Your company uses Microsoft Defender for Cloud Apps and wants to prevent users from uploading sensitive files to personal cloud storage apps. What should you configure?
Session policies, part of Conditional Access App Control, route user traffic through Defender for Cloud Apps as a reverse proxy, allowing synchronous inspection of each request and response. The proxy can evaluate conditions like device compliance, user risk, or file sensitivity and then block, allow, or restrict actions — including preventing uploads to unsanctioned apps before the request is passed through. This real-time inline enforcement is exactly what the scenario requires, making session policy the correct choice.
Why this answer
Session policy in Microsoft Defender for Cloud Apps allows real-time monitoring and control of user activities based on app and content inspection. By configuring a session policy, you can block or restrict uploads of sensitive files to personal cloud storage apps like Dropbox or Google Drive during the user's session, leveraging reverse proxy capabilities to inspect and intervene in traffic.
Exam trap
The trap here is that candidates confuse 'File policy' (which governs files at rest) with 'Session policy' (which governs files in motion), leading them to select D, even though real-time upload prevention requires session-level control via reverse proxy.
How to eliminate wrong answers
Option A is wrong because Activity policies are used for auditing and generating alerts on specific activities (e.g., multiple failed logins), not for real-time blocking of file uploads. Option B is wrong because App connectors enable API-based visibility and control for connected apps (e.g., retrieving logs), but they cannot intercept and block uploads in real time during a user session. Option D is wrong because File policies are designed for scanning and governing files already stored in cloud apps (e.g., detecting DLP violations in SharePoint), not for preventing uploads at the point of action.
