MS-900 Mobile Device Management (MDM) Practice Question
A business stakeholder asks how Microsoft 365 can help them manage laptops and mobile devices with compliance policies and app protection. Microsoft security, identity, or compliance capability should it use?
⚠ Common exam trap
Watch out — candidates often confuse productivity tools (Stream, Planner, Forms) with security and management services, but Microsoft 365 separates collaboration features from endpoint management, which is exclusively handled by Intune in this context.
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 Intune
Microsoft Intune is the correct answer because it is a cloud-based endpoint management solution that provides mobile device management (MDM) and mobile application management (MAM) capabilities. It allows administrators to enforce compliance policies (e.g., require PIN, encrypt device) and app protection policies (e.g., restrict copy/paste, prevent data leakage) on laptops and mobile devices, directly addressing the stakeholder's request.
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 Stream
Why it's wrong here
Microsoft Stream is an enterprise video service, holding no device compliance or app protection capability. It tempts because it appears in the Microsoft 365 admin centre alongside genuine device services, but it would be correct when an organisation needs to host and share recorded meetings and training videos internally.
- ✗
Microsoft Planner
Why it's wrong here
Microsoft Planner manages team task boards and plan assignments, offering no device enrolment, compliance policy or app protection enforcement. It tempts because it lives in Microsoft 365 and supports workflow tracking, but it would be correct when a team needs to organise tasks, buckets and deadlines for a project.
- ✗
Microsoft Forms
Why it's wrong here
Microsoft Forms collects surveys, quizzes and responses; it cannot enrol devices, evaluate compliance state or apply app protection policies. It tempts because it is a familiar Microsoft 365 workload reachable from the same portal, but it would be correct when gathering structured feedback or building a quiz.
- ✓
Microsoft Intune
Why this is correct
Microsoft Intune provides mobile device management and mobile application management, enforcing compliance policies and app protection on laptops and mobiles. This satisfies the stakeholder's device management and app protection requirement, unlike Entra ID, which handles identity and conditional access rather than device configuration.
