MS-900 Practice Question: Describe security, compliance, privacy, and trust in Microsoft 365
A compliance administrator needs to block sharing of documents containing credit card numbers. Which Microsoft 365 capability is the best fit?
⚠ Common exam trap
Many exam-takers confuse the OneDrive sync client with the OneDrive cloud service, thinking the sync client can enforce DLP policies locally, when in fact DLP policies are applied at the cloud service layer and the sync client simply replicates cloud-side restrictions.

Correct answer & explanation
✓
Data Loss Prevention policies
Data Loss Prevention (DLP) policies in Microsoft 365 are specifically designed to identify, monitor, and automatically protect sensitive information—such as credit card numbers—across Exchange Online, SharePoint, OneDrive, and Teams. By configuring a DLP policy with a built-in sensitive info type for credit card numbers, the administrator can block users from sharing documents containing that data, either by preventing the action or triggering a notification. This directly addresses the compliance requirement to block sharing of documents with credit card numbers.

Data Loss Prevention policies
Why this is correct

Microsoft Teams live events
Why it's wrong here
Teams events are for communication, not this compliance/security requirement.
- ✗
Microsoft Bookings

Bookings schedules appointments and is unrelated to this security requirement.
