EBS Snapshots occur ____.

A.
Asynchronously

B.
Synchronously

C.
Weekly

Explanation:
Snapshots occur asynchronously; the point-in-time snapshot is created immediately, but the status of the
snapshot is pending until the snapshot is complete (when all of the modified blocks have been transferred to
Amazon S3), which can take several hours for large initial snapshots or subsequent snapshots where many
blocks have changed. http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-creating-snapshot.html
