You are responsible for a legacy web application whose server environment is approaching the end of life. You would like to migrate this application to AWS as quickly as possible since the application environment currently has the following limitations.

Answer options:

A.Use the EC2 VM Import Connector for vCenter to import the VM into EC2.
B.Use VM Import/Export to import the VM as an Amazon Machine Image (AMI). Launch EC2 instances from the AMI.
C.Use S3 to create a backup of the VM and restore the data into EC2.
D.Use the EC2’s bundle-instance API to import an image of the VM into EC2.

Answer - B
Option A is Incorrect because EC2 VM Import Connector is a facility that builds on top of VM Import. We need the VM import in place for the connector to work.

Option B is correct because VM Import/Export offers several ways to import your virtual machine into Amazon EC2. VM Import/Export enables you to easily import virtual machine images from your existing environment to Amazon EC2 instances and export them back to your on-premises environment.
Option C is incorrect because the backup that is taken and stored on S3 may not be directly restored as an EC2 instance, and (b) it may not meet the RPO of 1 hour as this process will be slow for a large number of servers.
Option D is incorrect because (a) it is applicable to only instance store-backed Windows instance and the data on the volumes other than the root device volume does not get preserved, and (b) this API is not applicable to the Windows instances that are backed by EBS volumes.
