A customer has a single 3-TB volume on-premises that is used to hold a large repository of images and print
layout files. This repository is growing at 500 GB a year and must be presented as a single logical volume. The
customer is becoming increasingly constrained with their local storage capacity and wants an off-site backup of
this data, while maintaining low-latency access to their frequently accessed data. Which AWS Storage Gateway
configuration meets the customer requirements?
A.
Gateway-Cached volumes with snapshots scheduled to Amazon S3
B.
Gateway-Stored volumes with snapshots scheduled to Amazon S3
C.
Gateway-Virtual Tape Library with snapshots to Amazon S3
D.
Gateway-Virtual Tape Library with snapshots to Amazon Glacier

Stored Volumes – If you need “low-latency access” to your entire data set, you can configure your on-premises gateway to store all your data locally and then asynchronously back up point-in-time snapshots of this data to Amazon S3. This configuration provides durable and “inexpensive off-site backups” that you can recover to your local data center or Amazon EC2
