MS-102 Deploy and manage a Microsoft 365 tenant Practice Question
Your organization uses Microsoft Intune to manage Windows 10 devices. You need to deploy a custom Line-of-Business (LOB) app to a group of devices. The app is not in the Microsoft Store. What is the recommended method to deploy the app?
⚠ Common exam trap
A common mix-up: candidates confuse the Microsoft Store for Business (now Microsoft Store) as a viable publishing platform for custom LOB apps, not realizing that the store only accepts apps that meet Microsoft's submission requirements and is not designed for internal, proprietary applications.

Correct answer & explanation
✓
Upload the app package to Intune as a Line-of-Business app and assign it to the device group.
Intune natively supports deploying custom Line-of-Business (LOB) apps by uploading the app package (e.g., .msi, .exe, .appx) directly into the Intune console and assigning it to a device group. This method is the recommended approach for apps not available in the Microsoft Store, as it leverages Intune's mobile device management (MDM) capabilities to push the app to Windows 10 devices without requiring external infrastructure like Group Policy or the Microsoft Store for Business.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Add the app as a Microsoft Store app (business) in Intune.
Why it's wrong here
The 'Microsoft Store app (business)' type in Intune is reserved for apps that are synchronized from the Microsoft Store for Business catalog and identified by a store metadata record, such as a product ID and license details. Your custom internal application is not present in the store catalog, so this app type cannot be used to deploy a sideloaded package. Additionally, the Store for Business channel is deprecated, making it an even more unsuitable path for a custom line-of-business app.
- ✗
Use Group Policy to deploy the app via a network share.
Why it's wrong here
Group Policy software installation is delivered through its own client-side extension that runs only in an on-premises Active Directory or Hybrid AD environment, and it requires a reachable domain controller plus an authenticated network share for the installer source. Intune-managed Windows 10 devices do not process classic Group Policy settings directly from Intune, and a network share introduces connectivity/credential prereqs that cloud-only managed devices cannot satisfy in a zero-touch Intune workflow. Since the scenario specifically requires Intune, this is not an Intune-native mechanism and is therefore incorrect.
- ✗
Publish the app to the Microsoft Store for Business and assign it.
Why it's wrong here
The Microsoft Store for Business and Education does not provide a workflow for uploading custom line-of-business app packages; it is a purchasing and licensing platform for apps already published by developers/external publishers in the Store catalog, with volume licensing and private store capabilities. You cannot publish an internal, custom app package into that catalog, and any assignment of such an app from the store is technically impossible. This option also ignores the fact that Intune cannot simply 'assign' something that does not exist as a store product.
- ✓
Upload the app package to Intune as a Line-of-Business app and assign it to the device group.
Why this is correct
Upload the app package to Intune as a Line-of-Business app and assign it to the device group. This is the standard Intune method for side-loading a custom internal application: you navigate to Apps > All Apps > Add, choose the 'Line-of-business app' type, upload the MSI or APPX installable package, and then configure the assignment as Required to an Azure AD device group. Intune stores the package in Azure and handles download and installation on each enrolled Windows 10 device, making it the correct native deployment mechanism for a custom LOB application.
