B : Use an Auto Scaling policy with me DB B instance to automatically scale when tests are completed
C : Create a snapshot when tests are completed Terminate the DB instance and restore the snapshot when required
D : Modify the DB instance to a low-capacity D instance when tests are completed Modify the DB instance again when required
