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 company must comply with a regulation that requires all data stored in Microsoft 365 to remain within the European Union. Which Microsoft 365 feature should an administrator configure to enforce this geographic restriction?
Why wrong: DLP is used to prevent accidental sharing of sensitive information, not to enforce data storage locations.
B
Information Rights Management (IRM)
Why wrong: IRM protects documents by restricting actions like printing or forwarding, but does not control where data is stored.
C
Data Residency policies
Data Residency policies ensure that customer data is stored at rest within a specific geographic region, meeting regulatory requirements.
D
Customer Lockbox
Why wrong: Customer Lockbox provides approval control when Microsoft engineers need to access customer data for support, but does not enforce data residency.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Data Residency policies
Option C is correct because Data Residency policies in Microsoft 365 allow administrators to define the geographic location where data at rest is stored. By configuring a Data Residency policy for the European Union, the administrator ensures that all data remains within EU data centers, meeting regulatory requirements.
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 Data Residency policies with Data Loss Prevention (DLP) or Information Rights Management (IRM), mistakenly thinking those features control data location rather than focusing on data protection or access control.
Detailed technical explanation
How to think about this question
Data Residency policies in Microsoft 365 leverage Azure Active Directory conditional access and tenant-level configuration to map data to specific geographic regions (e.g., EU, US). Under the hood, these policies interact with Microsoft's data storage infrastructure, which uses Azure regions like North Europe and West Europe for EU data, ensuring compliance with regulations such as GDPR. A real-world scenario is a multinational company that must store customer data in the EU to comply with local data sovereignty laws, where Data Residency policies automatically route new data to approved EU data centers.

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.
