Your organization uses Microsoft Intune to manage Windows 11 devices. You need to configure a policy that prevents users from installing apps from outside the Microsoft Store. Which TWO settings can you use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use the 'AppLocker' settings in a device configuration profile to allow only Store apps.
In Intune, you can use a device configuration profile (Settings Catalog) to configure 'AppLocker' or 'SmartScreen' settings. Specifically, 'AppLocker' can block non-store apps, and 'SmartScreen' can block unknown apps. Option A and Option D are correct. Option B is wrong because Windows Defender Firewall does not control app installation. Option C is wrong because BitLocker is for encryption. Option E is wrong because Windows Update for Business controls updates.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

How this comes up in practice
A healthcare organisation deploys an application with a public-facing web tier and a private database tier.
