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

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

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

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








 

Suggested Answer: A

Community Answer: A

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.
