MS-900 Power Apps Practice Question
A department asks for the Microsoft 365 service best suited for custom low-code business apps. Which service should they use?
⚠ Common exam trap
Many exam-takers confuse security or compliance services (like Defender, PIM, or Compliance Manager) with development tools, failing to recognize that Power Apps is the dedicated low-code platform for custom business applications.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Power Apps
Power Apps is the correct choice because it is a low-code application development platform within Microsoft 365 that enables users to build custom business apps without extensive coding. It provides pre-built templates, connectors to Microsoft and third-party services, and a drag-and-drop interface, making it ideal for department-level custom app needs.
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 Defender for Endpoint
Why it's wrong here
Defender for Endpoint is endpoint detection and response, protecting devices from threats; it provides no app-building surface. It is tempting because it is a familiar Microsoft 365 security workload, and it would be correct when the requirement is endpoint threat detection rather than low-code development. Power Apps is the low-code service.
- ✗
Microsoft Entra Privileged Identity Management
Why it's wrong here
Privileged Identity Management grants just-in-time privileged role activation in Microsoft Entra ID; it has no application development capability. It is tempting because it is a governance service within the Microsoft 365 ecosystem, and it would be correct when the requirement is controlling standing administrative access. Power Apps builds low-code apps.
- ✗
Microsoft Purview Compliance Manager
Why it's wrong here
Compliance Manager assesses regulatory posture and tracks improvement actions against controls; it cannot build applications. It is tempting because it is a Microsoft 365 compliance workload administrators already use, and it would be correct when the requirement is measuring compliance score. Power Apps is the low-code app service.
- ✓
Power Apps
Why this is correct
Power Apps provides a low-code canvas and model-driven environment for building custom business applications with minimal hand-written code. It directly satisfies the department's requirement for a Microsoft 365 service suited to custom low-code business apps, unlike Power Automate or Power BI.
