MS-900 Describe Microsoft 365 apps and services Practice Question
A multinational organization wants a central hub for employee communication that includes company-wide announcements, topic-based communities, and the ability to integrate with SharePoint and Power BI dashboards. Which Microsoft 365 service is designed specifically for this purpose?
⚠ Common exam trap
Candidates often confuse Microsoft Teams' 'general' channel or SharePoint's news web part with a true company-wide social hub, but Viva Engage is the only service purpose-built for open, topic-based communities and organization-wide announcements with native integration to SharePoint and Power BI.

Correct answer & explanation
✓
Microsoft Viva Engage
Microsoft Viva Engage (formerly Yammer) is designed as a social networking and employee communication hub that provides company-wide announcements, topic-based communities, and seamless integration with SharePoint and Power BI dashboards. It focuses on fostering open communication across the organization, unlike collaboration tools that are team-centric.
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 it's wrong here
Microsoft Teams, while offering chat, meetings, and integration with SharePoint and Power BI, is primarily a real-time collaboration platform designed for specific workgroups and project-based communication. It lacks the dedicated enterprise-wide social networking features for broad company-wide announcements and extensive community management capabilities required for a central hub of topic-based communities across an entire organisation. Teams excels for focused team collaboration and online meetings.
- ✓
Microsoft Viva Engage
Why this is correct
Microsoft Viva Engage is an enterprise social network that allows organizations to create company-wide announcements, topic-based communities, and integrate with other apps like SharePoint and Power BI. It is the intended service for broad employee communication.
- ✗
SharePoint Online
Why it's wrong here
SharePoint Online is fundamentally a document- and intranet-centric platform, designed for storing, organizing, and managing content with versioning, metadata, and permissions. While it can display announcements through news posts or web parts, those are centrally authored, static communications rather than two-way employee conversations. In contrast, Viva Engage provides persistent, social community feeds with threaded discussions, @mentions, and member-driven engagement, which SharePoint's structured, page-based model is not intended to support as an organization-wide hub.
- ✗
Outlook
Why it's wrong here
Outlook is a personal productivity application centered on email, calendar, contacts, and tasks. Its email distribution lists or mail-enabled groups allow one-way or reply-all broadcasting, but they lack the persistent, topic-based community structure, content discovery, and integrated employee analytics that Viva Engage offers. Moreover, Outlook does not provide community governance features such as member roles, group moderation, or best-answer workflows, making it insufficient as a central hub for sustained, cross-organization conversations and leadership engagement.
