Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Microsoft Defender for Endpoint Attack Surface Reduction rules
ASR rules focus on device-level behavior, not granular control over cloud app file uploads.
B
Best answer
Microsoft Defender for Cloud Apps session policy
Session policies allow granular control of user sessions in SaaS apps, including blocking file uploads based on device compliance.
C
Distractor review
Microsoft Defender for Office 365 Safe Attachments
Safe Attachments scans email attachments for malware, not control of file uploads to cloud storage.
D
Distractor review
Microsoft Defender for Identity
Defender for Identity monitors on-premises AD for identity threats, not cloud app file upload activities.
