MD-102 Prepare infrastructure for devices Practice Question
You are troubleshooting a Windows 10 device that is not receiving required security updates from Microsoft Intune. The device is enrolled and shows as compliant. The update ring policy is assigned to the device. You check the Windows Update for Business logs and see that the deferral period is set correctly. What is the most likely cause?
⚠ Common exam trap
Watch out — candidates often assume a compliant device with a correctly configured policy will always receive updates, but they overlook the critical step of verifying that the device is actually a member of the assigned group, which is a separate prerequisite from compliance or policy configuration.

Correct answer & explanation
✓
The update ring is not assigned to the device's group.
The device is enrolled and compliant, and the deferral period is correctly set, which eliminates policy configuration issues. The most likely remaining cause is that the update ring policy is not assigned to the device's group, meaning the policy never reaches the device via Intune's policy delivery mechanism. Without proper group assignment, the Windows Update for Business settings are not applied, even if the device is compliant and the ring policy exists.
