MD-102 Manage applications Practice Question
You are troubleshooting an Intune deployment of a line-of-business (LOB) app for iOS. The app fails to install on some devices with error '0x87D13B9F'. Which THREE actions should you take to diagnose the issue?
⚠ Common exam trap

Correct answer & explanation
✓
Check if the device is supervised and that the app requires supervised mode
Error 0x87D13B9F in Intune for iOS LOB apps typically indicates a deployment restriction related to device supervision. If the app requires supervised mode (e.g., for managed app configuration or advanced MDM controls) and the target device is not supervised, Intune will fail to install the app with this error. Verifying supervision status is a primary diagnostic step.
