SC-900 Practice Question: Describe the capabilities of Microsoft compliance solutions
Fabrikam Inc., a global financial services company, uses Microsoft Purview to manage compliance. They have the following requirements: (1) Prevent users from sending emails containing credit card numbers (CCN) to external recipients; (2) automatically encrypt emails containing CCN; (3) notify users when an email is blocked; (4) allow users to override the block for business justifications; (5) generate incident reports for compliance teams. The company uses Microsoft 365 E5 licenses and has Exchange Online configured. The compliance team wants to implement a solution with minimal administrative overhead. What should the administrator configure?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a Data Loss Prevention (DLP) policy in the Microsoft Purview compliance portal with conditions for CCN, and configure actions to block, encrypt, notify, and allow override.
A DLP policy can block, encrypt, notify, and allow override, with incident reports. Option A is wrong because information barriers prevent communication between groups, not data exfiltration. Option C is wrong because sensitivity labels with auto-labeling classify but do not prevent sending. Option D is wrong because message encryption without DLP does not block or provide override.
