SC-900 Practice Question: Describe the capabilities of Microsoft security solutions
Your company uses Microsoft 365 Copilot to assist employees with drafting emails and documents. The security team needs to ensure that when Copilot accesses sensitive data, it respects the organization's sensitivity labels and does not expose highly confidential information to unauthorized users. What should the security team 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
✓
Apply Microsoft Purview sensitivity labels to data and enable Copilot data protection
Microsoft Purview sensitivity labels are integrated with Microsoft 365 Copilot to enforce data protection. When sensitivity labels are applied to data, Copilot respects those labels and restricts access to authorized users only. Option A is incorrect because Microsoft Defender for Cloud Apps session policies govern access to cloud apps, not Copilot's handling of labeled data. Option C is incorrect because disabling Copilot for all users would prevent any use, not just sensitive data access. Option D is incorrect because data loss prevention policies block sharing of sensitive data but do not control Copilot's internal access to labeled content.

- ✗
Configure Microsoft Defender for Cloud Apps session policies
Why it's wrong here
Configuring Microsoft Defender for Cloud Apps (MDCA) session policies is designed to enforce real-time controls over user sessions within cloud applications, often for conditional access or to prevent specific activities like downloads or uploads. While powerful for controlling user interactions with cloud services, these policies do not directly dictate how Microsoft 365 Copilot internally processes or respects Microsoft Purview sensitivity labels applied to data within the Microsoft 365 ecosystem. They operate at a different layer of control.
- ✓
Apply Microsoft Purview sensitivity labels to data and enable Copilot data protection
Why this is correct
Applying Microsoft Purview sensitivity labels to data is the foundational step for classifying and protecting sensitive information across Microsoft 365 applications and services. When combined with enabling Copilot data protection, this configuration ensures that Copilot respects these labels, preventing it from accessing or generating content based on data it shouldn't, or from exposing sensitive information to unauthorized users. This integration allows Copilot to operate securely within established data governance policies, leveraging AI responsibly.
- ✗
Disable Copilot for all users
Why it's wrong here
Disabling Microsoft 365 Copilot for all users is an extreme administrative action that completely removes the productivity benefits and AI assistance it offers. While it would prevent any potential misuse, this approach fails to address the core requirement of enabling secure Copilot functionality with sensitive data. It sacrifices valuable user productivity instead of implementing granular, intelligent data protection controls.
- ✗
Create a data loss prevention policy that blocks Copilot
Why it's wrong here
Creating a data loss prevention (DLP) policy to block Copilot is misaligned with the objective of securing Copilot's interaction with labeled data. DLP policies primarily focus on preventing sensitive information from being shared or exfiltrated outside defined organizational boundaries. They do not directly govern how Copilot processes or respects sensitivity labels internally within the Microsoft 365 ecosystem, which requires specific Copilot data protection configurations integrated with Purview.
