MS-900 Describe Microsoft 365 apps and services Practice Question
This MS-900 practice question tests your understanding of describe microsoft 365 apps and services. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 multinational corporation uses Microsoft 365 E5. They need to enforce that all documents marked as 'Confidential' are encrypted and cannot be printed or forwarded. Which Microsoft Purview Information Protection capability should they configure?
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 encryption
Sensitivity labels with encryption are the correct choice because they allow you to classify and protect documents at the file level, applying encryption that restricts actions such as printing and forwarding. This is a core capability of Microsoft Purview Information Protection, enabling persistent protection that travels with the document regardless of where it is stored or shared.
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 encryption
Why this is correct
Correct. Sensitivity labels can enforce encryption and usage restrictions.

✗
Data Loss Prevention (DLP) policies
Why it's wrong here
Incorrect. DLP policies detect and block sharing but do not encrypt or restrict printing.
✗
Retention policies
Why it's wrong here
Incorrect. Retention policies manage deletion, not encryption or usage rights.
✗
Azure Information Protection (AIP) client
Why it's wrong here
Incorrect. AIP is legacy; modern Purview uses sensitivity labels natively.
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 enforce encryption and restrict actions like printing, but DLP only monitors and alerts on content in transit or at rest, while sensitivity labels provide persistent, user-enforced protection at the file level.
Detailed technical explanation
How to think about this question
Sensitivity labels with encryption use Azure Rights Management (Azure RMS) to apply cryptographic protection, where the encryption key is managed in Azure AD and the policy is enforced via the Microsoft Purview compliance portal. When a document is labeled 'Confidential' with encryption, the label embeds a rights policy template that defines specific usage rights (e.g., deny print, deny forward), and these restrictions are enforced even when the document is shared externally or saved to a different location. In a real-world scenario, a multinational corporation can create a sub-label like 'Confidential - All Employees' that automatically encrypts documents and blocks printing and forwarding, ensuring compliance across global teams.
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 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.
