Your team has just created an AMI out of an EC2 Instance. You need to share it with another account. The account belongs to the same company. Which of the following is the right way to ensure the other account has access to the AMI?

Answer options:

A.Share the AMI with the specific AWS account.
B.Mark the AMI as public.
C.Sell the AMI in the AWS Marketplace.
D.Make the AMI as a paid AMI.

Correct Answer: A
The AWS Documentation mentions the following.
You can share an AMI with specific AWS accounts without making the AMI public. All you need are the AWS account IDs.
AMIs are a regional resource. Therefore, sharing an AMI makes it available in that region. To make an AMI available in a different region, copy the AMI to the region and then share it. 
All of the other options are not valid since these are not secure ways to share the AMI.
