MD-102 Manage applications Practice Question
An administrator deploys an iOS app as 'Required' to a group of devices using Intune. The app fails to install on some devices with error '0x87D13B9F'. What is the most likely cause?
⚠ Common exam trap
Many exam-takers confuse generic installation failures (like storage or compatibility) with the specific supervised-mode requirement, because the error code is not immediately intuitive and many assume 'Required' apps can install on any device.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The devices are not supervised
Error 0x87D13B9F in Intune indicates that the device is not supervised. For iOS/iPadOS, Intune requires devices to be in Supervised mode to install 'Required' apps silently without user interaction. Without supervision, the device cannot accept managed app installations pushed by MDM, causing the deployment to fail.
