MD-102 Manage and maintain devices Practice Question
You manage devices with Microsoft Intune. You need to ensure that only devices with a specific BIOS serial number can enroll. What should you configure?
⚠ Common exam trap
Candidates often confuse post-enrollment controls (compliance policies, Conditional Access) with pre-enrollment controls (enrollment restrictions), leading them to select options that only take effect after the device has already enrolled.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enrollment restrictions that block devices by hardware identifier.
Intune's enrollment restrictions allow you to block or allow devices based on hardware identifiers such as the BIOS serial number. By adding the specific BIOS serial numbers to the blocked hardware identifiers list, you can effectively prevent any device that does not match the allowed serials from enrolling. This is the only built-in mechanism in Intune that directly controls enrollment eligibility based on hardware characteristics.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Enrollment restrictions that block devices by hardware identifier.
Why this is correct
Enrollment restrictions can block devices based on hardware IDs like BIOS serial numbers.
- ✗
A device category with a dynamic group based on BIOS serial.
Why it's wrong here
Device categories are not used for enrollment blocking.
- ✗
A device compliance policy that checks BIOS serial number.
Why it's wrong here
Compliance policies cannot block enrollment; they only mark devices noncompliant.
- ✗
A Conditional Access policy that requires a compliant device.
Why it's wrong here
Conditional Access cannot prevent enrollment; it controls access after enrollment.
