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. The zone can o

nly be modified using the AWS CLI

B. It is not possible to change the zone of an instance after it is launched

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

D. From the AWS EC2 console, select the Actions – > Change zones and specify the

new zone

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 use

r cannot change the zone of that instance unless he creates an AMI of that instance and launches a new instance from it.
