MD-102 Manage and maintain devices Practice Question
You need to enforce encryption on Windows 10 devices managed by Intune. Which policy type should you configure?
⚠ Common exam trap
A common mix-up: candidates confuse Device Compliance Policies (which can check encryption status) with the actual policy that enforces encryption, leading them to select Option B, but compliance policies are read-only evaluations and cannot configure BitLocker settings.

Correct answer & explanation
✓
Endpoint Protection profile
Endpoint Protection profiles in Intune include the 'Windows Encryption' settings category, which allows you to enforce BitLocker Drive Encryption on Windows 10 devices. This profile directly manages encryption policies such as requiring BitLocker on OS and fixed drives, configuring encryption methods (e.g., XTS-AES 128-bit), and setting recovery password options. It is the correct policy type for enforcing encryption because it specifically targets security settings like device encryption and BitLocker.

Symmetric Encryption Algorithm Comparison
| Algorithm | Key Size | Block Size | Status | Notes |
|---|---|---|---|---|
| AES-128 | 128-bit | 128-bit | Current standard | NIST approved; WPA3, TLS |
| AES-256 | 256-bit | 128-bit | Current standard | Preferred for sensitive / govt data |
| 3DES | 112-bit effective | 64-bit | Deprecated (2023) | Replaced by AES |
| DES | 56-bit | 64-bit | Broken | Cracked in < 24 h; never deploy |
| ChaCha20 | 256-bit | Stream cipher | Current | TLS 1.3, WireGuard |
