Primary User: user@contoso.com
OS: Windows 11
Threat Level: High
Jailbroken: No
Encryption: Not Encrypted
A
Enable BitLocker encryption
The device is not encrypted, so enabling BitLocker will address the compliance issue.
B
Force a check-in
Why wrong: The device checked in recently; check-in is not the issue.
C
Remediate jailbreak status
Why wrong: Jailbreak is not applicable to Windows devices.
D
Install antivirus software
Why wrong: Antivirus may be needed, but the specific non-compliance is encryption.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable BitLocker encryption
The device is marked non-compliant because Intune's compliance policy requires BitLocker encryption on Windows devices. Enabling BitLocker satisfies that policy requirement, allowing the device to report as compliant on its next check-in.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse a non-compliant status with a connectivity or agent issue, and choose 'Force a check-in' instead of addressing the specific missing configuration (BitLocker) that caused the non-compliance.
Detailed technical explanation
How to think about this question
Intune compliance policies for Windows devices use the Configuration Service Provider (CSP) node `./Device/Vendor/MSFT/BitLocker/RequireDeviceEncryption` to enforce encryption. When this policy is set to 'Require', the device must have BitLocker enabled with a valid protector (e.g., TPM + PIN) to be compliant. The compliance state is cached and re-evaluated during each check-in cycle, which by default occurs every 8 hours.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
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.
