MS-700 Configure and Manage a Teams Environment Practice Question
Your organization wants to prevent users from sharing sensitive internal files with external guests in Teams. Which feature should you implement?
⚠ Common exam trap
The trap is confusing communication controls (External Access, Messaging policies) with data protection controls; candidates must recognize that only sensitivity labels apply persistent encryption and classification to files themselves.

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
✓
Microsoft Purview Sensitivity Labels.
Microsoft Purview Sensitivity Labels allow organizations to classify and protect content (including files shared in Teams) with encryption, content marking, and sharing restrictions. When applied to files, labels can enforce encryption that prevents external guests from opening or forwarding sensitive content, directly addressing the requirement to stop external sharing of internal files.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Teams Messaging policy.
Why it's wrong here
Messaging policies only manage chat-related behaviors, such as who can send messages or edit them. They have no control over file-level sharing permissions or external access to SharePoint resources, which is where sensitive files are actually stored and shared in a Microsoft Teams environment.
- ✓
Microsoft Purview Sensitivity Labels.
Why this is correct
Sensitivity labels allow you to define rules for how data should be handled. By applying these to teams or files, you can enforce policies that restrict external sharing, ensuring that sensitive content remains protected even if a user tries to share it externally with a guest user.
- ✗
Teams App setup policies.
Why it's wrong here
App setup policies control which applications appear in the user's Teams client sidebar. They are completely unrelated to data security, file-sharing permissions, or external access controls, making them irrelevant to the task of securing sensitive files against unauthorized external sharing by guests.
- ✗
External Access configuration.
Why it's wrong here
External access manages whether your users can chat or call people in other organizations. It does not govern the granular file-sharing permissions within a team. Even if external access is enabled, you still need sensitivity labels to control what specific data guests can access and share.
