MS-900 Describe Microsoft 365 apps and services Practice Question
A legal team needs to store documents with strict retention policies and eDiscovery capabilities. Which Microsoft 365 workload should they primarily use?
⚠ Common exam trap
The trap is that Microsoft Teams also stores files and supports compliance, so candidates pick Teams — but the question asks for the primary workload for document retention and eDiscovery, which is SharePoint Online (Teams files are actually stored in SharePoint behind the scenes).

Correct answer & explanation
✓
SharePoint Online
SharePoint Online is the Microsoft 365 workload that provides document libraries, retention labels, retention policies, and native eDiscovery (Content Search, eDiscovery cases, legal hold) capabilities. It is purpose-built for document storage and compliance, making it the correct primary workload for a legal team with strict retention and eDiscovery requirements. Retention policies configured in the Microsoft 365 compliance center apply directly to SharePoint sites and their document libraries.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Power BI
Why it's wrong here
Power BI delivers interactive reports and dashboards over data models; it holds no document repository, so retention labels and eDiscovery searches cannot apply to legal files. It is tempting because it surfaces organisational data visually, and would be correct when the requirement is analytics and reporting rather than document governance.
- ✗
Microsoft Bookings
Why it's wrong here
Microsoft Bookings publishes appointment scheduling pages tied to staff calendars; it stores no document library, so retention policies and eDiscovery cannot target legal records. It is tempting as a Microsoft 365 workload, and would be correct when the requirement is customer self-service booking rather than document governance.
- ✗
Microsoft Teams
Why it's wrong here
Microsoft Teams provides chat, meetings and channel collaboration, but its files live in SharePoint and its compliance scope covers conversations, not a dedicated legal document repository with retention and eDiscovery applied directly. It is tempting because Teams is a Microsoft 365 workload, and would be correct for team communication and meetings.
- ✓
SharePoint Online
Why this is correct
SharePoint Online provides document libraries governed by retention labels and holds, and its content is indexed for Microsoft Purview eDiscovery searches and cases. This directly satisfies the legal team's strict retention and eDiscovery requirements, unlike Teams or Exchange, which lack equivalent document lifecycle management.
