MD-102 Manage applications Practice Question
Your organization uses Microsoft Intune to manage devices. You need to deploy a custom Windows 10 line-of-business app that is not signed. Which action must you take on the target devices to allow installation?
⚠ Common exam trap
Watch out — candidates often confuse Developer Mode with sideloading, assuming that enabling Developer Mode is necessary for unsigned app installation, but Microsoft specifically separates these two settings for security and management clarity.

Correct answer & explanation
✓
Enable sideloading on the devices.
To install an unsigned line-of-business (LOB) app on Windows 10 via Intune, sideloading must be enabled on the target devices. Sideloading allows the installation of apps that are not signed by the Microsoft Store, which is required for custom LOB apps that lack a valid signature. This setting can be configured via a device configuration profile in Intune using the 'Allow sideloading of apps' policy.
