SC-900 Practice Question: Describe the capabilities of Microsoft security solutions
Your company is adopting Microsoft Copilot for Microsoft 365 to improve productivity. The security team is concerned about data leakage, as Copilot can access emails, documents, and other content. You need to ensure that sensitive data, such as credit card numbers and social security numbers, is not inadvertently exposed by Copilot. The organization uses Microsoft Purview sensitivity labels and DLP. You need to configure a solution that automatically detects and prevents Copilot from accessing or generating content containing these sensitive data types. What should you do?

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a DLP policy in Microsoft Purview that detects sensitive data types and blocks Copilot actions
Microsoft Purview Data Loss Prevention (DLP) policies can detect sensitive data types (e.g., credit card numbers, social security numbers) and automatically block or warn when Copilot for Microsoft 365 attempts to access or generate content containing such data. Option A is incorrect because Microsoft Defender for Cloud Apps is designed to control cloud app usage, but it does not integrate directly with Copilot for content-level data loss prevention. Option B is incorrect because disabling Copilot for certain users is a blunt approach that impacts productivity and does not provide targeted protection against data leakage. Option C is incorrect because while sensitivity labels help classify data, they alone do not prevent Copilot from accessing or generating sensitive content; DLP policies are required to enforce protection based on those labels.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Configure Microsoft Defender for Cloud Apps to control Copilot
Why it's wrong here
Defender for Cloud Apps is not the primary tool for Copilot DLP.
- ✗
Disable Copilot for users who handle sensitive data
Why it's wrong here
Disabling is not a targeted solution and reduces productivity.
- ✗
Apply sensitivity labels to all documents containing sensitive data
Why it's wrong here
Labels alone do not prevent Copilot from accessing data.
- ✓
Create a DLP policy in Microsoft Purview that detects sensitive data types and blocks Copilot actions
Why this is correct
DLP can monitor and block Copilot interactions with sensitive data.
