Quick Answer
The correct answer includes BitLocker, FileVault, and device encryption as the three valid encryption options Intune supports for enforcing disk encryption. BitLocker is the native full-disk encryption solution for Windows, while FileVault serves the same purpose for macOS, and device encryption is a built-in Windows feature that provides a lighter, automatic encryption layer on compatible hardware. On the Microsoft 365 Endpoint Administrator MD-102 exam, this question tests your ability to distinguish between full-disk encryption policies and file-level or OS-specific encryption methods. A common trap is confusing Encrypting File System (EFS) or Apple File System (APFS) encryption with Intune-managed disk encryption—EFS is per-file, not full disk, and APFS encryption is handled through FileVault, not as a separate policy. Remember the memory tip: “BitLocker for Windows, FileVault for Mac, device encryption for the built-in backup.”
This MD-102 practice question tests your understanding of manage and maintain 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.
An organization uses Microsoft Intune to manage Windows devices. They need to configure a policy to enforce disk encryption on devices. Which THREE of the following are valid encryption options?
BitLocker
BitLocker is a full disk encryption feature for Windows.
Encrypting File System (EFS)
Why wrong: EFS is file-level encryption, not full disk encryption managed by Intune.
Device encryption
Device encryption is a built-in encryption feature on Windows devices.
FileVault
FileVault is full disk encryption for macOS.
APFS encryption
Why wrong: APFS encryption is file-level or volume-level, but Intune uses FileVault for macOS encryption.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
BitLocker
Options A, C, and D are correct. BitLocker is for Windows devices, FileVault is for macOS, and device encryption is a built-in Windows feature. Option B is wrong because Encrypting File System (EFS) is file-level encryption, not full disk encryption. Option E is wrong because Apple File System (APFS) encryption is for macOS, but it's not a separate policy in Intune; FileVault is used.
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.
