MS-900 Practice Question: Describe security, compliance, privacy, and trust in Microsoft 365
This MS-900 practice question tests your understanding of describe security, compliance, privacy, and trust in microsoft 365. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
A global financial services firm needs to protect highly confidential documents containing trade secrets. The protection must restrict access to a specific group of employees, prevent editing and printing, and remain enforced even if the document is downloaded and saved to an external device. Which Microsoft Purview solution should be used?
Correct. Sensitivity labels apply encryption and usage restrictions (view, edit, print) that follow the document even when stored externally.
B
Data Loss Prevention (DLP) policy
Why wrong: Incorrect. DLP policies detect and block sharing of sensitive data but do not apply persistent protection that remains with the file after download.
C
Information Barriers
Why wrong: Incorrect. Information Barriers restrict communication between groups but do not protect documents.
D
Advanced Audit
Why wrong: Incorrect. Advanced Audit logs user activities but does not enforce restrictions on documents.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Sensitivity labels (Azure Information Protection)
Sensitivity labels from Azure Information Protection (AIP) allow you to classify and protect documents with persistent protection that travels with the file, even when it is downloaded to an external device. By configuring a sensitivity label with encryption, you can restrict access to a specific group of employees, disable editing and printing, and enforce these restrictions regardless of where the file is stored. This meets all the requirements of the scenario, including persistent protection after download.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse DLP policies with sensitivity labels, thinking DLP can protect files after download, but DLP only monitors and blocks at the point of sharing, not persistently encrypting the file.
Detailed technical explanation
How to think about this question
Under the hood, sensitivity labels leverage Azure Rights Management (Azure RMS) to apply encryption using the AES-256 algorithm and enforce usage rights via an XrML license embedded in the file. This license is evaluated by the RMS client on any device, ensuring that even if the file is copied to a USB drive, the encryption and rights (e.g., deny edit, deny print) remain enforced. A real-world scenario is a financial firm sharing a trade-secret PDF with external auditors; the label can be set to expire access after 30 days, preventing access after the audit period.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
