A company uses Microsoft Intune to manage devices. They want to deploy a custom line-of-business (LOB) app to Windows 10 devices that are not enrolled in Intune but are joined to Azure AD. Which deployment method should they use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Deploy the app as a Microsoft Store for Business app and assign to Azure AD-joined devices.
Option A is correct because Microsoft Store for Business allows you to deploy apps to Azure AD-joined devices that are not enrolled in Intune. The app can be assigned directly to Azure AD-joined devices via the Store for Business portal, which uses the Azure AD identity to push the app without requiring Intune enrollment.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume Intune is required for any app deployment to Azure AD-joined devices, but Microsoft Store for Business can deploy apps directly to Azure AD-joined devices without Intune enrollment.
Detailed technical explanation
How to think about this question
Microsoft Store for Business uses the Windows Store client to deliver apps to Azure AD-joined devices via the 'OfflineLicensed' app type, which does not require Intune MDM. The deployment leverages Azure AD authentication and the Windows Store for Business sync service, allowing apps to be installed silently in the system context. This method is ideal for organizations that want to manage app deployment without full device management overhead.

Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
