MS-900 Describe Microsoft 365 apps and services Practice Question
A project team needs to create a central workspace where they can store project documents, assign tasks, track a shared calendar of milestones, and have threaded discussions about each item. The solution must integrate directly with Microsoft Teams. Which Microsoft 365 service provides this out-of-the-box?
⚠ Common exam trap
Watch out — candidates often confuse Planner or Microsoft Lists as a complete workspace solution, but they lack the document storage, calendar, and threaded discussion capabilities that SharePoint Online provides out-of-the-box.
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 provides a central workspace with document libraries for storing project documents, task lists for assignment, shared calendars for milestones, and discussion boards for threaded conversations. It integrates natively with Microsoft Teams via the SharePoint tab, allowing the team to access all these features directly within the Teams interface without additional configuration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
SharePoint Online
Why this is correct
SharePoint Online provides the full collaborative workspace the team needs: a team site includes document libraries for file storage and versioning, list apps for tracking tasks and issues, a shared calendar web part, and a discussion board for threaded conversations. These capabilities can also be surfaced directly inside Microsoft Teams via tabs, making SharePoint the underlying storage and permissions backbone for Teams-connected teamwork.
- ✗
Microsoft Lists
Why it's wrong here
Microsoft Lists is a data-tracking application that lets users create structured lists for things like issue tracking or inventory, with custom columns and views. However, it is a component of a SharePoint site rather than a full workspace: it does not provide document libraries with coauthoring, a team calendar, or out-of-the-box threaded discussion capabilities, so it fails the stem's requirement for a central hub with all those features.
- ✗
Planner
Why it's wrong here
Planner is a lightweight task management service focused on kanban-style boards, buckets, and assignments, with charts to monitor progress. It does not include its own document storage (files live in a linked SharePoint library if enabled), nor does it provide a shared calendar or per-item discussion threads, so it cannot deliver the integrated document, calendar, and conversation experience described.
- ✗
Project Online
Why it's wrong here
Project Online lacks the native threaded discussions per item and the integrated shared calendar with task assignment that the stem requires; it is a project portfolio management tool focused on scheduling, resource planning, and reporting, not a collaborative workspace. It is tempting because it handles project milestones and task tracking, making it the correct choice when the need is for enterprise project management with detailed Gantt charts and resource levelling, rather than a lightweight, Teams-integrated hub for document storage and conversational collaboration.

Same concept, more angles
3 more ways this is tested on MS-900
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A sales team needs a centralized repository for customer proposals that multiple team members can edit simultaneously and that maintains version history. Which Microsoft 365 service should they use?
easy- A.OneDrive for Business
- ✓ B.SharePoint Online
- C.Microsoft Teams
- D.Exchange Online
Why B: SharePoint Online is the correct choice because it provides a centralized document library where multiple users can co-author documents simultaneously, with built-in version history to track changes over time. This aligns directly with the requirement for a shared repository with real-time collaboration and versioning, which OneDrive for Business lacks for team-wide access.
Variation 2. A project manager needs a centralized location to store all project documents, assign tasks to team members, and track project milestones. The solution must integrate with Microsoft Teams and allow real-time co-authoring. Which Microsoft 365 service should they use?
medium- A.Microsoft Planner
- B.Microsoft Project Online
- ✓ C.Microsoft SharePoint Online
- D.Microsoft To Do
Why C: SharePoint Online provides document libraries for storing files with real-time co-authoring, plus lists for tracking tasks and milestones. It integrates deeply with Teams through tabs. Microsoft Planner is task-focused but does not natively store documents. Project Online is more complex and expensive. To Do is for personal tasks.
Variation 3. A project team needs a centralized workspace that includes a shared calendar, a document library for storing deliverables, a task list with assignments, and the ability to have threaded discussions about each item. They want a solution that is available out of the box in Microsoft 365 and integrates with Microsoft Teams. Which service should they use?
medium- A.Microsoft Teams
- ✓ B.SharePoint team site
- C.Microsoft Viva Engage
- D.Microsoft Planner
Why B: A SharePoint team site provides a team-oriented workspace with a document library for files, a shared calendar, a tasks list, and a discussion board for threaded conversations. It can be added as a tab in Teams. Teams alone does not include all these features natively.
