MD-102 Protect devices Practice Question
You manage Windows 10 devices with Intune. You need to ensure that only approved apps can run on corporate devices. You configure AppLocker via a custom OMA-URI. However, users can still run unapproved apps. What is the most likely reason?
⚠ Common exam trap
The trap is that candidates may overlook the enforcement mode of AppLocker policies, assuming they block by default, when 'Audit only' mode is a common configuration that logs but does not prevent execution.
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 AppLocker policy is set to 'Audit only' mode.
When AppLocker is configured via custom OMA-URI in Intune, the policy is device-based and can be assigned to device groups. However, if the policy is set to 'Audit only' mode, it only logs events without actually blocking applications. This allows users to still run unapproved apps. Option D is incorrect because assigning the policy to a device group does enforce AppLocker rules; the issue here is mode enforcement, not assignment type.
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 device must be running Windows 10 Pro edition.
Why it's wrong here
AppLocker is supported on Windows 10 Pro, Enterprise and Education, so edition is not the blocker. The failure stems from the OMA-URI configuration itself. Edition would matter for features restricted to Enterprise, such as some Defender Application Control scenarios.
- ✗
AppLocker rules can only be configured via Group Policy, not OMA-URI.
Why it's wrong here
AppLocker rules can be delivered through Intune custom OMA-URI using the ApplicationControl CSP, so this claim is false. The real fault lies in the OMA-URI path or rule XML. Group Policy is chosen when managing domain-joined devices without MDM enrolment.
- ✓
The AppLocker policy is set to 'Audit only' mode.
Why this is correct
Audit-only mode logs AppLocker events without blocking execution, so unapproved apps still launch despite the deployed policy. Switching the enforcement setting to Enforce makes the rules actively prevent unapproved applications from running on the managed devices.
- ✗
The policy is assigned to a device group instead of a user group.
Why it's wrong here
AppLocker enforcement is device-scoped; assigning to a device group is valid and does not explain the failure. The actual cause is that the custom OMA-URI path or policy configuration is incorrect. Device targeting would be right when applying machine-wide rules independent of who signs in.
