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?
Correct: This is the standard method for deploying LOB apps via Intune.
Why this answer
Option D is correct because 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.
Exam trap
The trap here is that candidates may 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.
How to eliminate wrong answers
Option A is wrong because adding the app as a Microsoft Store app (business) in Intune is intended for apps that are already available in the Microsoft Store for Business, not for custom LOB apps that are not in the store. Option B is wrong because Group Policy deployment via a network share is a traditional on-premises method that does not integrate with Intune's cloud-based MDM, and it requires devices to be domain-joined and connected to the corporate network, which is not recommended for modern, cloud-managed environments. Option C is wrong because publishing a custom LOB app to the Microsoft Store for Business is not supported; the store only accepts apps that meet specific submission criteria and are not intended for internal, proprietary line-of-business applications.
