Sensitivity Label Policies — Encryption and Watermarking | Microsoft 365 Fundamentals Explained
This MS-900 practice question tests your understanding of describe microsoft 365 apps and services. 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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
It encrypts the document and adds a watermark.
The Microsoft Purview sensitivity label policy configures both encryption (via protection settings) and watermarking (via marking settings). When applied to a document, it enforces both actions simultaneously, resulting in the document being encrypted and watermarked. Therefore, option A is correct.
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 may assume a sensitivity label only performs one action (either encryption or watermarking) and overlook that Microsoft Purview allows combining multiple protection and marking actions in a single label policy.
Detailed technical explanation
How to think about this question
Under the hood, Microsoft Purview sensitivity labels use Azure Information Protection (AIP) to apply encryption via Azure Rights Management (Azure RMS), which enforces usage restrictions like view-only or edit permissions. The watermark is rendered as a persistent overlay (e.g., 'CONFIDENTIAL' text) that is embedded in the document’s visual layer and cannot be removed without breaking the label. In a real-world scenario, a legal department might apply this label to a merger document to ensure only authorized reviewers can open it (encryption) while discouraging screenshots (watermark).

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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
