A user has launched an EBS backed EC2 instance. The user has rebooted the instance. Which of the below
mentioned statements is not true with respect to the reboot action?
A.
The private and public address remains the same
B.
The Elastic IP remains associated with the instance
C.
The volume is preserved
D.
The instance runs on a new host computer
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 the Amazon EC2 to reboot the instance instead of running the operating system reboot command
from the instance. The instance remains on the same host computer and maintains its public DNS name,
private IP address, and any data on its instance store volumes. It typically takes a few minutes for the reboot to
complete, but the time it takes to reboot depends on the instance configuration.

“When you reboot an instance, it remains on the same physical host, so your instance keeps its public DNS name, private IP address, and any data on its instance store volumes.”
