When controlling access to Amazon EC2 resources, each Amazon EBS Snapshot has a ______ attribute that controls which AWS accounts can use the snapshot.
A . createVolumePermission
B . LaunchPermission
C . SharePermission
D . RequestPermission

Answer: A

Explanation:

Each Amazon EBS Snapshot has a createVolumePermission attribute that you can set to one or more AWS Account IDs to share the AMI with those AWS Accounts. To allow several AWS Accounts to use a particular EBS snapshot, you can use the snapshots’s createVolumePermission attribute to include a list of the accounts that can use it.
