Microsoft Azure Administrator Associate AZ-104 Practice Question

Alex cannot assign roles at the 'Operations' subscription level because his 'User Access Administrator' role assignment is scoped to the 'Networking' resource group. Role assignments are only effective within their assigned scope and any child resources. Since Alex's role is assigned at the resource group level, he can only assign roles within the 'Networking' resource group, not at the subscription level. To assign roles at the subscription level, he would need the 'User Access Administrator' role assigned at the subscription scope.

Option A is incorrect because the 'User Access Administrator' role does grant permissions to assign roles. Option C is incorrect because, while the 'Owner' role includes permissions to assign roles, Alex can also assign roles with the 'User Access Administrator' role if assigned at the correct scope. Option D is incorrect because there's no indication of a deny assignment; the issue is due to the scope of Alex's role assignment.
