Your organization uses Microsoft Intune to manage Windows 11 devices. You notice that some devices are not receiving security updates even though update rings are assigned. What is the most likely cause?
Deferral periods can significantly delay update installation.
Why this answer
Update ring policies in Microsoft Intune include a deferral period setting that delays the installation of updates for a specified number of days after Microsoft releases them. If a deferral period is configured (e.g., 30 days for feature updates or 7 days for quality updates), devices will not receive security updates until that period expires, even though the update ring is assigned. This is a common configuration to allow testing before broad deployment, but it can mistakenly be overlooked when troubleshooting missing updates.
Exam trap
The trap here is that candidates often assume missing updates are due to compliance or connectivity issues, but the MD-102 exam specifically tests the understanding that deferral periods in update rings can delay security updates even when the policy is correctly assigned.
How to eliminate wrong answers
Option A is wrong because noncompliant devices are not blocked from receiving security updates; Intune can still deliver updates to noncompliant devices, though compliance policies may restrict access to corporate resources. Option B is wrong because the question states that devices are managed by Intune and have update rings assigned, which implies they are enrolled; if they were not enrolled, they would not appear in Intune at all. Option D is wrong because if devices were not connected to the internet, they would not be able to communicate with Intune or Windows Update, but the question specifies that update rings are assigned and the issue is specifically about security updates not being received, not a complete lack of connectivity.
