MS-900 Describe Microsoft 365 apps and services Practice Question
A department asks for the Microsoft 365 service best suited for department document libraries with version history. Which service should they use?
⚠ Common exam trap
Candidates often confuse Microsoft Purview Compliance Manager's compliance features with document version history, but version history is a core SharePoint Online capability, not a compliance or security tool.
Answer choices
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
✓
SharePoint Online
SharePoint Online is the correct answer because it provides document libraries with built-in version history, allowing users to track, restore, and manage previous versions of documents. This feature is essential for collaboration and compliance, as it enables rollback to earlier versions and audit trails without additional configuration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Microsoft Purview Compliance Manager
Why it's wrong here
Microsoft Purview Compliance Manager assesses compliance posture and tracks improvement actions; it hosts no document libraries or version history. It is tempting because it is a Microsoft 365 compliance service, and would be correct when the department needs regulatory assessment scoring rather than document storage.
- ✓
SharePoint Online
Why this is correct
SharePoint Online provides department document libraries with built-in version history, retaining prior versions of files and enabling restore. It is the Microsoft 365 service purpose-built for team document storage and collaboration, matching the department's requirement.
- ✗
Microsoft Entra Privileged Identity Management
Why it's wrong here
Privileged Identity Management grants just-in-time privileged role activation in Microsoft Entra ID; it stores no documents and provides no versioning. It is tempting as a governance control, and would be correct when the requirement is approving, time-limiting and auditing elevated administrator role assignments.
- ✗
Microsoft Defender for Endpoint
Why it's wrong here
Defender for Endpoint is endpoint detection and response, protecting devices from threats; it holds no document storage, so it cannot host libraries or version history. It is tempting because it is a genuine Microsoft 365 security service, and would be correct when the requirement is threat detection, investigation and remediation on endpoints.
