The answer is to check the Intune management extension logs on a failed device. This is correct because when an Intune LOB app installation failure occurs with a .msi file, the Intune management extension handles the download and execution, and its logs—located at C:\ProgramData\Microsoft\IntuneManagementExtension\Logs—contain the precise error code or missing dependency that caused the failure. On the MD-102 exam, this scenario tests your ability to differentiate between configuration issues and client-side execution problems; a common trap is to assume re-assigning the app or adding scripts will fix it, but the logs reveal whether the installer itself failed due to a prerequisite like a missing .NET framework or a blocked execution policy. Remember the memory tip: “Logs before scripts, errors before re-assigns”—always check the device-side logs first to pinpoint the root cause of any LOB app installation failure.
MD-102 Protect devices Practice Question
This MD-102 practice question tests your understanding of protect devices. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Your company has 500 Windows 10 devices that are Hybrid Azure AD joined and managed by Microsoft Intune. You need to deploy a new line-of-business (LOB) app to all devices. The app is packaged as a .msi file. You create a new app in Intune and assign it to a device group containing all devices. After 24 hours, some devices report the app as 'Installed' but others show 'Failed'. You verify that the devices are online and have network connectivity. What should you do next to resolve the installation failures?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Check the Intune management extension logs on a failed device.
Option B is correct because the most common cause of .msi installation failures is missing prerequisites or dependencies. Checking the Intune management extension logs on the device will reveal the specific error. Option A is wrong because the app is already assigned; re-assigning won't fix underlying issues. Option C is wrong because the app is already targeted to all devices. Option D is wrong because scripts are not needed; the issue is likely with the app itself.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Use a PowerShell script to install the app on failed devices.
Why it's wrong here
Scripts might help but logs are needed to diagnose first.
✓
Check the Intune management extension logs on a failed device.
Why this is correct
Logs will show the specific error code or dependency issue.

Read the scenario before looking for a memorised answer.
✗
Create a new device group and assign the app again.
Why it's wrong here
Group membership is not the issue.
✗
Re-assign the app to the device group.
Why it's wrong here
Re-assigning won't resolve the underlying installation error.

TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
