The suggested answer is A, D.
When a script is executed using the Device Database option, the changes are made to the device database, not directly to the managed devices. Thus, to apply these changes to the managed devices, you must install them using the Install Wizard, making statement A correct. Additionally, when changes are made to the device database, the Device Settings Status will be tagged as Modified, reflecting that there are uninstalled changes in the database, making statement D correct. Therefore, statements A and D are the two correct statements.
