MD-102 Manage and maintain devices Practice Question
Your organization uses Microsoft Intune to manage devices. You need to ensure that only corporate-owned Windows 10 devices are allowed to access Microsoft 365 services. You have configured a conditional access policy to require compliant devices. What else must you do to identify corporate-owned devices?
⚠ Common exam trap
Many exam-takers confuse device compliance policies with ownership identification, not realizing that compliance policies evaluate security posture, not ownership, and that corporate identifiers are the dedicated Intune feature for marking devices as corporate-owned.

Correct answer & explanation
✓
Add corporate device identifiers (e.g., serial numbers) in Intune.
Corporate device identifiers, such as serial numbers or IMEI numbers, are the specific mechanism in Microsoft Intune used to mark a device as corporate-owned. While a conditional access policy requiring compliant devices ensures only compliant devices can access Microsoft 365, it does not distinguish between corporate and personal devices. By uploading corporate identifiers, Intune automatically sets the ownership type to 'Corporate' upon enrollment, which can then be used in conditional access policies to restrict access to only those devices.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Configure a device compliance policy to require corporate ownership.
Why it's wrong here
Compliance policies cannot require corporate ownership; ownership is a tag.
- ✗
Set enrollment restrictions to block personally owned devices.
Why it's wrong here
Enrollment restrictions block enrollment but do not mark devices as corporate.
- ✗
Deploy an app protection policy to block personal devices.
Why it's wrong here
App protection policies do not set device ownership.
- ✓
Add corporate device identifiers (e.g., serial numbers) in Intune.
Why this is correct
Corporate identifiers allow Intune to automatically mark devices as corporate-owned upon enrollment.
