MD-102 Manage and maintain devices Practice Question
You need to ensure that Windows 10 devices in your organization receive the latest quality updates within 7 days of release. You configure a Windows Update for Business policy in Intune with a deferral period of 7 days. After two weeks, some devices have not installed the updates. What is the most likely reason?
⚠ Common exam trap
It's easy for candidates to assume that configuring a Windows Update for Business policy in Intune immediately applies to all targeted devices, overlooking the critical requirement for devices to complete an Intune sync before the policy takes effect.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Devices have not synced with Intune to receive the updated policy.
Windows Update for Business policies in Intune are not applied in real time; devices must check in with the Intune service to receive the updated policy. The default sync interval for Intune-managed Windows 10 devices is approximately 8 hours, and if a device has not synced since the policy was configured, it will not yet have the new deferral settings. This explains why some devices have not installed the updates even after two weeks, as they may have missed the sync window or have a longer check-in cycle.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The devices are configured to receive updates from WSUS instead of Windows Update.
Why it's wrong here
WSUS would override WUfB, but the stem assumes WUfB is used.
- ✗
The deferral period is too short; Microsoft recommends 14 days.
Why it's wrong here
7 days is valid.
- ✗
The policy is configured to apply only to devices in a specific Azure AD group.
Why it's wrong here
The stem implies the policy targets all devices.
- ✓
Devices have not synced with Intune to receive the updated policy.
Why this is correct
Devices must sync to get the policy; if they miss sync, updates are not enforced.
