MS-900 Describe Microsoft 365 apps and services Practice Question
A sales team needs to collaborate on a document in real time and track changes. Which Microsoft 365 app is most suitable?
⚠ Common exam trap
Many exam-takers confuse Microsoft Teams as a document collaboration tool because it displays files, but Teams relies on Word for the web for actual editing; the question specifically asks for the app that enables real-time editing and change tracking, which is Word for the web, not Teams.

Correct answer & explanation
✓
Word for the web
Word for the web (Option C) is the most suitable app because it is specifically designed for real-time co-authoring, allowing multiple users to edit a document simultaneously while tracking changes via the built-in version history and 'Track Changes' feature. Unlike desktop Word, the web version requires no manual sync and leverages Microsoft's Fluid Framework for seamless collaboration across devices.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
OneNote
Why it's wrong here
OneNote is fundamentally a digital notebook designed for capturing notes, ideas, and clippings, not for creating or editing formal documents. While it does support real-time collaboration on its pages, it lacks the structured editing, pagination, track changes, and version history features required for document co-authoring that Word for the web provides. Therefore, it cannot serve as a primary tool for a sales team collaboratively writing a single document.
- ✗
Microsoft Forms
Why it's wrong here
Microsoft Forms is a tool for creating surveys, quizzes, and polls, capturing structured responses into a data table rather than enabling simultaneous editing of a prose document. It does not offer a free-form canvas, formatting controls, or a co-authoring model that multiple people can use to edit a document in real time. Hence, it is entirely unsuitable for collaborative document creation.
- ✓
Word for the web
Why this is correct
Word for the web is the correct choice because it was purpose-built for document authoring and includes native real-time co-authoring, allowing multiple users to edit the same document simultaneously with visible presence indicators. It also provides track changes, comments, and version history, all of which are essential for a sales team iterating on a document together. Because it synchronizes through OneDrive or SharePoint, every collaborator immediately sees updates without conflict.
- ✗
Microsoft Teams
Why it's wrong here
Microsoft Teams is a communication and collaboration hub that centralizes chats, meetings, and file storage, but it does not itself provide document editing capabilities. While a document can be stored in a Teams channel, opening it launches Word for the web or another Office app—editing never occurs natively within the Teams interface. Therefore, Teams is a place to share and discuss the document, not the tool the sales team would use for real-time co-authoring.
