You have maintained an AWS Organization and the Organization has below OUs (Organizational Units) configured:

Answer options:

A.In the tree view of AWS Organization console, drag and drop QA_Department and its members to be a child of Dev_Department.
B.Move accounts 3 and 4 out of the AWS Organization, move QA_Department to be a child of Dev_Department. Add accounts 3 and 4 back to QA_Department.
C.Create a new OU under Dev_Department named QualityAssurance_Department. Move accounts 3 & 4 to the new OU. Delete the original empty OU QA_Department.
D.Move accounts 3 and 4 under the Root of the AWS Organization. Use CLI move-organizational-unit to move QA_Department to be a child of Dev_Department. Then add accounts 3 and 4 to QA_Department.

Correct Answer – C
For OUs, there are limited operations that users can do. Please check
https://docs.aws.amazon.com/organizations/latest/userguide/orgs_manage_ous.html.
One thing to note is that the user cannot move an OU to another place from the console or CLI command. So the user has to create a new OU and move accounts to it.
Option A is incorrect: because the user cannot drag and drop an OU to another place.
Option B is incorrect because it is unnecessary to move accounts out of the Organization. Otherwise, you have to re-invite these accounts.
Option C is CORRECT because users can move accounts from an OU to another. After that, empty OU can be deleted.
Option D is incorrect because there is no such CLI command to move an Organizational Unit.
