The applications running on the instances store data in instance memory (RAM) that must be present when the instances resume operation.
Which approach should the solutions architect recommend to shut down and resume the instances?
- Modify the application to store the data on instance store volumes. Reattach the volumes while restarting them.
- Snapshot the instances before stopping them. Restore the snapshot after restarting the instances.
- Run the applications on instances enabled for hibernation. Hibernate the instances before the shutdown.
- Note the Availability Zone for each instance before stopping it. Restart the instances in the sameAvailability Zones after the shutdown.
