In Microsoft Intune, applications are assigned to Azure Active Directory (Azure AD) objects.
The supported assignment targets include users and specific types of groups.
Supported Groups: Security groups (both 'Assigned' and 'Dynamic' membership) and
Microsoft 365 groups are security-enabled and can be used for app and policy assignments.
Therefore, Group1 (Microsoft 365), Group3 (Security - Assigned), and Group4 (Security -
Dynamic User) are all valid targets.
Unsupported Groups: Distribution groups are used for email distribution lists and are not
security principals. They cannot be used to assign apps or policies in Intune. Therefore,
Group2 is an invalid target.
Users: While individual users like Admin1 can be targeted for assignments, Option C
correctly identifies all the valid group types from the list, which aligns with the best practice
of managing assignments at scale.
