Answer options

• A. Copy the running instance using the ג€Instance Copyג€ command to the EU region
• B. Create an AMI of the instance and copy the AMI to the EU region. Then launch the instance from the EU AMI
• C. Copy the instance from the US East region to the EU region
• D. Use the ג€Launch more like thisג€ option to copy the instance from one region to another

Correct answer: B

Explanation

To replicate an EC2 instance across AWS regions for disaster recovery, you must first create an Amazon Machine Image (AMI) of the source instance, copy that AMI to the destination region, and launch a new instance from it. Direct cross-region instance copying or cloning via "Launch more like this" is not supported. This process also allows the user to select a smaller instance type during the launch phase in the destination region.
