Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may think Microsoft Teams alone covers all collaboration needs, forgetting that SharePoint Online is the underlying file storage and co-authoring engine for Teams channel files.
Detailed technical explanation
How to think about this question
Under the hood, each Teams channel has a dedicated SharePoint document library where files are stored, and co-authoring leverages the Office Online Server (or Microsoft 365) real-time synchronization protocol, which uses WebSocket connections for near-instant updates. In a real-world scenario, a project team can simultaneously edit a Word document in a Teams channel while discussing changes in a meeting, with version history automatically managed by SharePoint.

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 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.
