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 security administrator needs to automatically restrict access to documents that contain 'PII' (personally identifiable information) so that only employees in the 'Data Privacy' security group can view them. Additionally, editing and printing of these documents must be disabled. Which combination of Microsoft Purview features should be used?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Sensitivity labels with auto-labeling and encryption that restricts permissions to the 'Data Privacy' group
Option A is correct because sensitivity labels in Microsoft Purview can be configured with auto-labeling to automatically detect and classify documents containing PII, and then apply encryption that restricts access to only the 'Data Privacy' security group. Additionally, the label can enforce usage rights such as 'View Only' to disable editing and printing, meeting all requirements.
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.
✓
Sensitivity labels with auto-labeling and encryption that restricts permissions to the 'Data Privacy' group
Why this is correct
Sensitivity labels can automatically classify documents containing PII and enforce encryption, allowing only authorized users with view-only rights.
Related concept

✗
Data Loss Prevention (DLP) policy with a block action
Why it's wrong here
DLP policies block sharing but do not control access or permissions once the document is stored.
✗
Retention policy with a restrict action
Why it's wrong here
Retention policies preserve or delete data; they cannot restrict viewing or editing permissions.
✗
Privileged Identity Management (PIM)
Why it's wrong here
PIM manages privileged access for administrators, not document-level permissions.
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, not realizing that DLP blocks data in motion or at rest but cannot enforce persistent document-level permissions like disabling editing or printing.
Detailed technical explanation
How to think about this question
Sensitivity labels use Azure Information Protection (AIP) encryption, which applies Rights Management Services (RMS) templates to enforce granular usage restrictions like 'View Only' (no edit/print). Auto-labeling leverages trainable classifiers or exact data match (EDM) to detect PII patterns such as Social Security numbers or credit card numbers, and can be triggered at document creation or modification. The encryption binds the policy to the document itself, persisting even if the file is copied or emailed outside the tenant.

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.
