A user has launched two EBS backed EC2 instances in the US-East-1a region. The user wants to change the zone of
one of the instances. How can the user change it?

A.
Stop one of the instances and change the availability zone

B.
The zone can only be modified using the AWS CLI

C.
From the AWS EC2 console, select the Actions – > Change zones and specify new zone

D.
Create an AMI of the running instance and launch the instance in a separate AZ

Explanation:
With AWS EC2, when a user is launching an instance he can select the availability zone (AZ) at the time of launch. If the
zone is not selected, AWS selects it on behalf of the user. Once the instance is launched, the user cannot change the
zone of that instance unless he creates an AMI of that instance and launches a new instance from it.
