- A
Microsoft Purview Data Lifecycle Management
Why wrong: Data Lifecycle Management is about retention and deletion policies, not classification or protection of sensitive content.
- B
Microsoft Purview Data Loss Prevention (DLP)
Why wrong: DLP can detect sensitive data and enforce actions like blocking, but it does not automatically apply sensitivity labels and encryption. DLP policies can complement labels but are not the primary solution for automated labeling.
- C
Microsoft Purview Information Protection with auto-labeling
Auto-labeling policies in Purview Information Protection can automatically classify and protect documents based on content, applying the appropriate sensitivity label (including encryption and access restrictions) without user intervention.
- D
Microsoft Purview Insider Risk Management
Why wrong: Insider Risk Management focuses on detecting risky user behavior (e.g., data exfiltration), not on automatic classification of documents.
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. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 compliance officer needs to automatically classify documents stored in SharePoint Online that contain personally identifiable information (PII) such as social security numbers. The classification must apply a sensitivity label that encrypts the document and restricts access to only employees in the Legal department. The process should run without any user interaction. Which Microsoft Purview solution should be configured?

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 Information Protection with auto-labeling
Option C is correct because Microsoft Purview Information Protection with auto-labeling can automatically detect PII (e.g., social security numbers) in documents stored in SharePoint Online and apply a sensitivity label that encrypts the content and restricts access to the Legal department. This process runs without user interaction, meeting the compliance officer's requirement for automatic classification and protection.
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 (which block sharing) with auto-labeling policies (which apply sensitivity labels and encryption), but DLP does not automatically encrypt or restrict access via sensitivity labels.
Detailed technical explanation
How to think about this question
Auto-labeling in Purview Information Protection uses sensitive information types (e.g., predefined patterns for social security numbers) and machine learning classifiers to scan content at rest in SharePoint Online. When a match occurs, the policy applies a sensitivity label that triggers encryption via Azure Information Protection (AIP) and sets permissions (e.g., only Legal department members can decrypt). This process runs as a background task without requiring user input, and labels can be applied to existing or newly uploaded documents.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
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.
