MD-102 Manage applications Practice Question
You are an administrator for a company that uses Microsoft Intune. You have an iOS line-of-business (LOB) app that you need to deploy to all iOS devices. The app is signed with an enterprise certificate. You upload the app to Intune and assign it as required. Users report that the app fails to install. What is the most likely cause?
⚠ Common exam trap
The trap here is assuming that the assignment type or enrollment method is the issue, when the most common cause of iOS LOB app installation failure is an invalid or expired provisioning profile.

Correct answer & explanation
✓
The app is not properly signed with a valid provisioning profile.
iOS line-of-business apps must be signed with a valid provisioning profile that supports enterprise distribution. If the provisioning profile is expired, does not include the necessary devices, or is otherwise invalid, the app will fail to install. This is the most likely cause when an enterprise-signed app fails to deploy. Proper signing and provisioning are critical for successful iOS LOB app deployment via Intune.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The app was not packaged using the Microsoft Win32 Content Prep Tool.
Why it's wrong here
The Microsoft Win32 Content Prep Tool is used for Windows Win32 apps, not iOS apps. iOS LOB apps are uploaded as .ipa files directly. Using the Win32 tool would not be applicable and would not affect iOS app installation. This option is incorrect because it references a tool for a different platform, and the scenario is about iOS devices.
- ✗
The app assignment is set to required, but it should be set to available for iOS LOB apps.
Why it's wrong here
Required assignments are valid for iOS LOB apps and will force installation on targeted devices. Available assignments allow users to install on demand. Both are supported. The failure is not due to the assignment type; required is appropriate for ensuring the app is installed on all devices. The issue likely lies with the app's signing or provisioning, not the assignment.
- ✗
The iOS devices are not enrolled in Intune as corporate-owned devices.
Why it's wrong here
Intune supports both corporate-owned and personally owned iOS devices. While some app types or policies may require corporate ownership, LOB apps can generally be deployed to any enrolled device, provided the app is properly signed. The enrollment type is not the primary cause of installation failure in this scenario. The most common cause is an invalid provisioning profile or signing issue.
- ✓
The app is not properly signed with a valid provisioning profile.
Why this is correct
iOS LOB apps must be signed with a valid provisioning profile that includes the devices' UDIDs or uses enterprise distribution. If the provisioning profile is invalid, expired, or does not include the necessary devices, installation fails. Since the app is signed with an enterprise certificate, the provisioning profile must be correctly configured for enterprise distribution. A common cause of failure is an expired or misconfigured provisioning profile.
