You have a Microsoft Intune subscription.
You have three security groups named Security1, Security2 and Security3. Security1 is the parent group of
Security2. Security2 has 100 users.
You need to change the parent group of Security2 to be Security3.
What should you do first?

A.
Edit the properties of Security1.

B.
Edit the properties of Security2.

C.
Delete security2.

D.
Remove all users from Security2.

Explanation:
You cannot change the parent group of a security group in Microsoft Intune. You can only delete the group and
recreate another group with the correct parent.
Deleting a group does not delete the users that belong to that group. Therefore, you do not need to remove the
users from the group; you can just delete the group and recreate it.
Incorrect Answers:
A: You cannot change the parent of a group by modifying the properties of the parent group.
B: You cannot change the parent of a group by modifying the properties of the group.
D: Deleting a group does not delete the users that belong to that group. Therefore, you do not need to remove
the users from the group; you can just delete the group and recreate it.
