A user has launched an EC2 instance from an instance store backed AMI. If the user restarts the
instance, what will happen to the ephermal storage data?

A.
All the data will be erased but the ephermal storage will stay connected

B.
All data will be erased and the ephermal storage is released

C.
It is not possible to restart an instance launched from an instance store backed AMI

D.
The data is preserved

Explanation:
A user can reboot an EC2 instance using the AWS console, the Amazon EC2 CLI or the Amazon
EC2 API. Rebooting an instance is equivalent to rebooting an operating system. However, it is
recommended that the user use Amazon EC2 to reboot the instance instead of running the
operating system reboot command from the instance. When an instance launched from an
instance store backed AMI is rebooted all the ephermal storage data is still preserved.
