The answer is to deploy Microsoft Purview Information Protection with sensitivity labels. This is correct because Copilot for Microsoft 365 reads the encryption, marking, and access restrictions embedded in these labels at the content level, ensuring the AI model cannot generate responses that expose classified data—directly addressing the search intent around copilot sensitivity labels data leakage. On the MS-102 exam, this tests your understanding that Copilot does not natively enforce data governance; it relies on Purview’s label policies to block leakage, a common trap being candidates who mistakenly choose DLP policies alone, which only monitor data in transit rather than enforce content-level restrictions. Remember the memory tip: “Labels lock Copilot’s lips”—if a document has a sensitivity label, Copilot respects its boundaries, preventing the model from leaking protected information.

After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Your company is planning to adopt Microsoft Copilot for Microsoft 365. The security team is concerned about data leakage. What must you implement to ensure that Copilot respects your organization's sensitivity labels and data classification?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Deploy Microsoft Purview Information Protection with sensitivity labels
Microsoft Purview Information Protection with sensitivity labels is the correct answer because Copilot for Microsoft 365 uses these labels to enforce data governance at the content level. When a sensitivity label is applied to a document or email, Copilot respects that label's encryption, marking, and access restrictions, preventing the model from generating responses that leak classified data. This is the foundational mechanism for ensuring Copilot adheres to your organization's data classification policies.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Use Microsoft Defender for Cloud Apps to control Copilot
Why it's wrong here
Defender for Cloud Apps provides visibility and control over cloud apps, but not specifically Copilot's label awareness.
✗
Configure Data Loss Prevention (DLP) policies
Why it's wrong here
DLP policies protect data from being shared inappropriately but do not directly control Copilot's behavior.
✓
Deploy Microsoft Purview Information Protection with sensitivity labels
Why this is correct
Copilot respects sensitivity labels to prevent data leakage.

✗
Enable Customer Lockbox
Why it's wrong here
Customer Lockbox controls Microsoft support access, not Copilot.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse DLP policies (which monitor and block data in transit or at rest) with sensitivity labels (which define and enforce data classification at the content level), leading them to choose DLP as the solution for controlling Copilot's behavior.
Detailed technical explanation
How to think about this question
Under the hood, Copilot integrates with the Microsoft Purview Information Protection SDK to read sensitivity labels and their associated protection policies (e.g., encryption keys from Azure Information Protection). When a user interacts with Copilot, the model's context retrieval engine filters out content that the user does not have permission to access based on label-based rights management. In a real-world scenario, if a document is labeled 'Highly Confidential' with encryption, Copilot will not include its content in responses to unauthorized users, even if the document is in the same SharePoint site.

Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
