MS-900 Describe Microsoft 365 apps and services Practice Question
A manager wants to create a team site to collaborate with external partners on a project. They need to share documents with external users and control permissions. Which Microsoft 365 service should they use?
⚠ Common exam trap
Many candidates confuse Microsoft Teams as the primary collaboration tool for external sharing, but Teams relies on SharePoint for file storage and permission management, making SharePoint the correct answer when the question emphasizes creating a team site and controlling permissions.

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 choice because it provides team sites with granular permission controls, including the ability to share documents with external users via secure links or direct invitations. It supports external sharing at the site level, allowing the manager to collaborate with partners while maintaining control over permissions and document access.

- ✗
Microsoft Viva Connections
Why it's wrong here
Microsoft Viva Connections is a personalized employee experience dashboard, typically surfaced within Teams, that aggregates news, tasks, and organizational resources. It does not create or host a dedicated site for external users and lacks the document libraries, site permissions, and external-sharing controls required for collaborating with external partners. Therefore, it cannot fulfill a request to create an external-sharing team site.
- ✗
Microsoft Teams
Why it's wrong here
Microsoft Teams is a chat-centric collaboration workspace, and while files shared in channels are stored in SharePoint Online behind the scenes, Teams itself does not offer a team-site creation experience or site-level permission management. Creating a 'Team' provisions a Microsoft 365 group and a linked SharePoint site, but the actual site resource is SharePoint Online, not Teams. Because the manager specifically asked to create a team site, Teams is not the correct product to directly meet that request.
- ✗
OneDrive for Business
Why it's wrong here
OneDrive for Business is a private, personal document library tied to an individual user's account, designed for storing and sharing the user's own files rather than hosting a structured multi-user team site. Although it supports external link-sharing options, it does not offer site-level granular permissions, multiple document libraries, or the collaborative site lifecycle that a SharePoint Online team site provides. Thus it is inappropriate as the target for a dedicated collaboration site.
- ✓
SharePoint Online
Why this is correct
SharePoint Online team sites are the correct solution because they provide a dedicated, cloud-hosted collaboration site with document libraries, lists, page content, and granular permission settings. Site-level external sharing can be enabled in the SharePoint admin center to invite external users with specific roles such as site member or visitor, giving the manager the needed control. This matches the requirement of creating a team site for external collaboration better than any of the other options.
