Correct answer & explanation
Microsoft Teams with SharePoint Online
Microsoft Teams integrates with SharePoint Online to provide a centralized document repository where team files are stored and managed.

Common exam traps
The trap here is that candidates might confuse Microsoft Teams as a standalone chat app, overlooking its deep integration with SharePoint Online for file storage and collaboration, or mistakenly think Planner or Forms can serve as document repositories.
Detailed technical explanation
When a team is created in Microsoft Teams, a corresponding SharePoint Online site is automatically provisioned, and the 'Files' tab in each channel maps directly to a document library in that site. This integration uses SharePoint's underlying REST APIs and WebDAV protocol for file operations, enabling real-time co-authoring and version history without emailing attachments. In a real-world scenario, a department head can share a link to a document in a Teams conversation, and all members with permissions can edit simultaneously, with changes synced instantly via SharePoint's change tracking.
Key takeaway
Microsoft Teams channels store files in SharePoint Online document libraries.
Real-world example
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
