Quick Answer
The correct answer is the App protection policy – Data protection – Encrypt app data setting. This is because Intune App Protection Policy (APP) encrypts corporate data at rest on iOS by leveraging the device’s hardware-backed Data Protection class, which ties the encryption key to the user’s device passcode, ensuring that managed app data remains inaccessible if the device is lost or stolen. On the MD-102 exam, this question tests your ability to distinguish between app-level encryption (configured under Data Protection in APP) and device-level encryption (such as BitLocker or FileVault), a common trap where candidates mistakenly choose a device compliance policy. Remember that for iOS, the "Encrypt app data" setting within APP is the only way to enforce encryption of corporate data inside managed apps without requiring full device enrollment. A helpful memory tip: think of APP as the "app armor" that wraps around your data, while device encryption protects the entire phone—for managed app data on iOS, always look under Data Protection.
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.
Your organization uses Microsoft Intune to manage iOS/iPadOS devices. You need to ensure that corporate data in managed apps is encrypted at rest. Which setting should you configure?
Device compliance policy – Require data encryption.
Why wrong: This encrypts the device, not app data.
App protection policy – Data protection – Encrypt app data.
Encrypts app data at rest.
Enrollment restrictions – Require encrypted backup.
Why wrong: Not related to app data encryption.
Device configuration profile – Encryption settings.
Why wrong: Does not encrypt app data.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
App protection policy – Data protection – Encrypt app data.
Option B is correct because App Protection Policies (APP) in Microsoft Intune include a 'Data Protection' setting called 'Encrypt app data' that enforces encryption of corporate data at rest on iOS/iPadOS devices. This setting uses hardware-backed file-level encryption (Data Protection class) to protect data in managed apps, ensuring that even if the device is lost or stolen, the data remains inaccessible without the user's passcode.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Device compliance policy – Require data encryption.
Why it's wrong here
This encrypts the device, not app data.
App protection policy – Data protection – Encrypt app data.
Why this is correct
Encrypts app data at rest.
Related concept

Enrollment restrictions – Require encrypted backup.
Why it's wrong here
Not related to app data encryption.
Device configuration profile – Encryption settings.
Why it's wrong here
Does not encrypt app data.
Common exam traps
The trap here is that candidates often confuse device-level encryption (which is always on for iOS with a passcode) with app-level encryption, and incorrectly choose a Device Compliance Policy or Configuration Profile, not realizing that only App Protection Policies can enforce encryption specifically for corporate data within managed apps.
Detailed technical explanation
The 'Encrypt app data' setting in Intune APP leverages the iOS Data Protection API, which uses a class-based encryption scheme (e.g., NSFileProtectionComplete) to encrypt files at rest with a key derived from the user's passcode. This ensures that data in managed apps is encrypted even when the device is locked, and the encryption key is not accessible to other apps or services. In a real-world scenario, if a user loses their iPhone, an attacker cannot read corporate email or documents from the managed Outlook or SharePoint app without the device passcode, even if they bypass the lock screen.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.

Variation 1. Your organization uses Microsoft Intune to manage iOS devices. You need to ensure that corporate data is protected when users access Microsoft 365 apps. Which policy should you configure?
hardWhy B: Option C is correct because App Protection Policies (APP) in Intune protect data at the app level, including for Microsoft 365 apps, without requiring device management. Option A is wrong because Conditional Access controls access, not data protection within apps. Option B is wrong because Device Compliance policies ensure devices are compliant, but do not protect data within apps. Option D is wrong because Mobile App Configuration policies configure app settings, not protect data.
