MS-900 Describe Microsoft 365 apps and services Practice Question
A marketing team needs to collaborate on a presentation that will be updated frequently by multiple team members, and they want to ensure everyone always has the latest version without manual tracking. Which Microsoft 365 service should they use?
⚠ Common exam trap
A common mix-up: candidates confuse Microsoft Teams as the collaboration service itself, but Teams relies on SharePoint Online for file storage and versioning, so the correct underlying service is SharePoint.
Answer choices
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 a centralized document library with version history, co-authoring, and metadata management, ensuring all team members always access the latest version without manual tracking. Unlike OneDrive for Business, which is designed for individual use, SharePoint Online supports structured collaboration across a team with granular permissions and automated sync.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Exchange Online
Why it's wrong here
Exchange Online is a cloud-hosted email and calendaring service that manages mailboxes and messages. While users can attach a presentation to an email, those attachments are separate copies stored in each person's mailbox; Exchange has no concept of a shared document library, co-authoring, or version history. Thus, it cannot serve as the collaborative environment the marketing team needs for a single presentation.
- ✓
SharePoint Online
Why this is correct
SharePoint Online provides cloud-based team sites with document libraries that support simultaneous co-authoring, check-in/check-out, version history, and granular access controls. When users open a PowerPoint presentation from a SharePoint library, edits are tracked and saved back to the central location, enabling multiple marketing teammates to work on the same file in real time. This makes SharePoint Online the correct service for organized team collaboration on a presentation.
- ✗
Microsoft Teams
Why it's wrong here
Microsoft Teams is a chat-centric collaboration hub that integrates channels and meetings, and it offers a 'Files' tab within each channel. However, the actual document storage and collaboration features are delegated to the underlying SharePoint site, not to Teams itself; Teams provides the communication layer and shortcuts to files rather than acting as a full-fledged document management system. Without SharePoint, Teams cannot supply the versioning and permissioning needed for a shared presentation project.
- ✗
OneDrive for Business
Why it's wrong here
OneDrive for Business is a personal cloud storage library tied to an individual's user account, designed for files owned by that user. Even though it does support sharing and co-authoring, it lacks the team-wide management capabilities of SharePoint, such as shared team site governance, metadata tagging, and approval workflows. For a marketing team requiring a central, collaborative workspace, OneDrive is not the correct choice because it is oriented toward personal file storage rather than a team document repository.
