Quick Answer
The answer is a device restrictions configuration policy. This is the correct choice because device restrictions in Microsoft Intune include a specific setting to block unknown sources on Android Enterprise, which directly prevents users from sideloading apps from outside the Google Play Store. On the MD-102 exam, this question tests your ability to distinguish between policy types that enforce security settings versus those that merely report or configure apps—a common trap is confusing compliance policies, which only check and report on the installation of unknown sources, with device restrictions, which actively block the action. Remember that compliance policies are for auditing and conditional access, while device restrictions are for enforcing the actual block. A helpful memory tip: restrictions restrict actions, compliance checks conditions.
This MD-102 practice question tests your understanding of prepare infrastructure for devices. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 manage a fleet of Android Enterprise devices. You need to configure a policy that prevents users from installing apps from unknown sources. Which policy type should you use?
Device restrictions configuration policy
Device restrictions can disable unknown sources.
Device compliance policy
Why wrong: Compliance policy can mark devices noncompliant, but doesn't block installation.
App configuration policy
Why wrong: App configuration policies configure within apps, not device-wide.
Enrollment restriction
Why wrong: Enrollment restrictions limit which devices can enroll.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Device restrictions configuration policy
Option C is correct because device restrictions include settings to block unknown sources. Option A is wrong because compliance policy checks security, but doesn't block installation. Option B is wrong because app configuration policies configure apps, not device settings. Option D is wrong because enrollment restrictions control enrollment, not app installation.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
