This MD-102 practice question tests your understanding of manage applications. 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.
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?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Check if the device is supervised and that the app requires supervised mode
Options A, B, and E are correct. Verify the app is signed with a valid Apple Developer Enterprise certificate; expired certificates cause failures. Check that the device is not supervised if required; some LOB apps require supervised mode. Ensure the device has enough storage; error can be storage-related. Option C is wrong because Intune Service Health is not specific to app deployment. Option D is wrong because app configuration policies are optional.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.

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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
