Quick Answer
The correct answer is to trigger a manual evaluation of the dynamic group in Azure AD. This is necessary because Azure AD dynamic group membership is not recalculated immediately after an Azure AD Connect sync; instead, it relies on a background evaluation process that can take up to 24 hours to reflect attribute changes. Even though the sync successfully updated the department attribute for the 20 users, the dynamic group’s rule engine must be explicitly re-run to remove them from 'SalesGroup'. On the MS-102 exam, this scenario tests your understanding of the separation between attribute synchronization and group membership evaluation—a common trap is assuming a successful sync automatically updates dynamic groups. To remember this, think: “Sync updates the data, but you must manually re-evaluate the rule.” A quick memory tip is “Sync fills the tank, but you have to turn the key to drive the group update.”
This MS-102 practice question tests your understanding of manage users, groups, licensing, and support. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
You are the Microsoft 365 administrator for Contoso Ltd., a company with 500 users. The company uses a hybrid identity with Azure AD Connect. You have a dynamic group named 'SalesGroup' that includes all users with department attribute equal to 'Sales'. Recently, the HR system updated the department for 20 users from 'Sales' to 'Marketing'. The Azure AD Connect sync completed successfully, and the attribute changes are reflected in Azure AD. However, after 48 hours, these users are still members of 'SalesGroup'. You need to ensure that the group membership accurately reflects the department attribute within the next hour. The solution must use minimal administrative effort. What should you do?
Remove the users from the group manually
Why wrong: Dynamic groups are not meant for manual changes.
Delete and recreate the dynamic group with the same rule
Why wrong: Disruptive and time-consuming.
Trigger a manual evaluation of the dynamic group in Azure AD
Forces immediate membership update.
Wait another 24 hours for the next automatic evaluation
Why wrong: May not solve issue and time-sensitive.

Correct answer & explanation
Trigger a manual evaluation of the dynamic group in Azure AD
Option C is correct because Azure AD dynamic groups are not automatically re-evaluated immediately after a sync; they rely on a periodic background evaluation process that can take up to 24 hours. By triggering a manual evaluation in the Azure AD admin center or via PowerShell (using the `Invoke-MgGraphRequest` or `Update-MgGroup` cmdlet), you force an immediate recalculation of group membership based on the current attribute values, ensuring the 20 users are removed from SalesGroup within the hour with minimal administrative effort.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
The trap here is that candidates assume dynamic groups are evaluated immediately after an attribute sync, but Microsoft deliberately tests the understanding that dynamic group membership evaluation is asynchronous and can take up to 24 hours unless manually triggered.
Detailed technical explanation
Azure AD dynamic group membership evaluation is governed by a background process that runs every 24 hours by default, but the actual interval can vary based on tenant load and group size. The evaluation uses the `onPremisesExtensionAttributes` or cloud-based attributes like `department`; after a successful Azure AD Connect sync, the attribute change is stored in Azure AD, but the dynamic group engine only picks it up during its next scheduled evaluation cycle. Triggering a manual evaluation via the Azure portal or the `Invoke-MgGraphRequest -Method POST -Uri 'https://graph.microsoft.com/v1.0/groups/{groupId}/evaluateDynamicMembership'` endpoint forces an immediate recalculation, bypassing the 24-hour wait.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
