MS-102 Manage compliance by using Microsoft Purview Practice Question
You are a compliance administrator for Fabrikam Inc. The company uses Microsoft Purview Information Barriers. You need to prevent users in the Sales department from communicating with users in the Research department in Microsoft Teams. However, both departments must be able to communicate with the Legal department. What should you do first?
⚠ Common exam trap
The trap here is assuming DLP or Teams messaging policies can enforce ethical walls, when information barriers are the purpose-built solution.

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 an information barrier segment for each department and define blocked and allowed communication policies between them.
Information barriers are the correct feature to restrict communication between specific groups in Microsoft Teams. The first step is to create segments for each department, then define policies that specify which segments can communicate. This allows blocking Sales-Research while permitting both to communicate with Legal.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create a DLP policy that blocks Teams messages between Sales and Research.
Why it's wrong here
DLP policies can block messages containing sensitive information, but they do not prevent communication between entire departments based on user attributes. Information barriers are specifically designed for ethical walls and communication restrictions between groups, whereas DLP is content-based.
- ✓
Create an information barrier segment for each department and define blocked and allowed communication policies between them.
Why this is correct
Information barriers use segments to group users and policies to define allowed or blocked communication between segments. You must first create segments for Sales, Research, and Legal, then define policies that block Sales-Research and allow Sales-Legal and Research-Legal. This is the foundational step to enforce the restriction.
- ✗
Assign sensitivity labels to users in Sales and Research to prevent collaboration.
Why it's wrong here
Sensitivity labels are applied to content, not users, and they do not enforce communication restrictions between groups. While labels can restrict access to documents, they do not prevent chat or calls between users in different departments.
- ✗
Configure a Teams messaging policy that disables chat for the Sales and Research departments.
Why it's wrong here
Teams messaging policies control features like chat, but they cannot selectively block communication between two specific departments while allowing communication with a third. They apply to users or groups uniformly and do not support attribute-based ethical walls.
