MS-900 Describe Microsoft 365 apps and services Practice Question
Which three of the following are Microsoft 365 apps and services that are primarily designed for productivity and collaboration? (Choose three.)
⚠ Common exam trap
Watch out — candidates often confuse security or identity services (like Intune, Microsoft Entra ID, or Defender) with productivity tools, because they are part of the Microsoft 365 ecosystem, but the question specifically asks for apps and services 'primarily designed for productivity and collaboration.'

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 is a core Microsoft 365 workload because it provides a unified collaboration hub for chat, meetings, video calls, and real-time file coauthoring. It is one of the primary apps users access daily, and it directly integrates with other Microsoft 365 services like SharePoint, OneDrive, and Exchange Online, making it a correct answer to this question.
- ✓
Microsoft Exchange Online
Why this is correct
Microsoft Exchange Online is the cloud-hosted messaging platform in Microsoft 365 that delivers enterprise-grade email, shared calendars, contacts, and mail archiving. It is considered a primary service because it is the foundational communication layer for all Microsoft 365 tenants, and nearly every user depends on it for day-to-day correspondence and scheduling.
- ✓
Microsoft SharePoint Online
Why this is correct
Microsoft SharePoint Online is a primary content management and collaboration service in Microsoft 365 that provides team sites, document libraries, and intelligent intranet capabilities. It powers file storage and sharing for Teams and OneDrive, and organizations rely on it as the core platform for structured content, business applications, and portal experiences, making it a correct answer.
- ✗
Microsoft Intune
Why it's wrong here
Microsoft Intune is not a primary user-facing app or collaboration service; rather, it is a cloud-based unified endpoint management solution for managing Windows, macOS, iOS, and Android devices. It is an important IT administration tool within Microsoft 365, but it is not one of the core apps and services that users directly leverage for communication, content, or productivity.
- ✗
Microsoft Microsoft Entra ID
Why it's wrong here
Microsoft Microsoft Entra ID (now Microsoft Entra ID) provides identity and access management capabilities such as authentication, single sign-on, and conditional access, so it works in the background of Microsoft 365. It is not an app or service that users open to produce content or communicate; it is an infrastructure service, which is why it is not considered one of the primary user-facing Microsoft 365 apps.
- ✗
Microsoft Defender for Office 365
Why it's wrong here
Microsoft Defender for Office 365 is a security-focused service that protects an organization against malicious email links, phishing, and malware in Exchange Online, SharePoint, and OneDrive. It is an additional protection layer for other Microsoft 365 workloads, not a core productivity app or collaboration service for end users, so it is incorrect for this question.
