MS-900 Describe Microsoft 365 apps and services Practice Question
A project team needs to collaborate on personal work files that follow a user across devices and co-author related Office files. Which two Microsoft 365 capabilities are most relevant?
⚠ Common exam trap
Many candidates confuse SharePoint Online document storage as only for team sites, but it is also the underlying storage for OneDrive for Business, making both B and C correct for personal files that follow a user and co-authoring, as OneDrive provides the user-specific sync and SharePoint provides the backend storage and sharing infrastructure.
