MS-900 Describe Microsoft 365 apps and services Practice Question
A project team needs to collaborate on Teams channel conversations and meetings and co-author related Office files. Which two Microsoft 365 capabilities are most relevant?
⚠ Common exam trap
Candidates often think Microsoft Teams alone covers all collaboration needs, forgetting that SharePoint Online is the underlying file storage and co-authoring engine for Teams channel files.
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
✓
Microsoft Teams
Microsoft Teams (A) is correct because it is the Microsoft 365 service that provides channel conversations, chat, and meetings, which directly satisfy the collaboration and meeting requirements. SharePoint Online document storage (B) is correct because Teams channels are backed by SharePoint Online, and SharePoint provides the co-authoring and versioned document storage for the related Office files. Microsoft Purview eDiscovery case (C) is not relevant because it is used for legal hold, search, and investigation of content, not for day-to-day collaboration or co-authoring. Exchange anti-malware policy (D) is not relevant because it protects mail flow from malicious attachments and links, not Teams conversations, meetings, or Office file co-authoring.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Microsoft Teams
Why this is correct
Microsoft Teams supplies persistent channel conversations and scheduled meetings, forming the collaboration hub the project team needs. This satisfies the stem's requirement for channel discussions and meetings, while file co-authoring is delivered through the integrated SharePoint and Office workloads.
- ✓
SharePoint Online document storage
Why this is correct
SharePoint Online provides the document libraries where Office files are stored and co-authored simultaneously by multiple users. This satisfies the stem's co-authoring requirement, complementing Teams, which handles the conversations and meetings rather than the file storage layer.
- ✗
Microsoft Purview eDiscovery case
Why it's wrong here
Microsoft Purview eDiscovery case manages legal hold, search and review of content for litigation; it does not host channel conversations, meetings or co-authoring. It would be the right choice when a legal team must preserve and export evidence, not when a project team needs day-to-day collaboration.
- ✗
Exchange anti-malware policy
Why it's wrong here
Exchange anti-malware policy scans mail flow for malicious attachments and URLs; it neither hosts Teams conversations nor enables file co-authoring. It would be correct when an administrator must block malware in email, not when a project team needs to collaborate in channels and meetings.
