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.
