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

Cached Volumes – You store your data in Amazon Simple Storage Service (Amazon S3) and retain a copy of frequently accessed data subsets locally. Cached volumes offer a substantial cost savings on primary storage and minimize the need to scale your storage on-premises. You also retain low-latency access to your frequently accessed data.
Not B – they don’t need low latency to all data set, just frequently accessed data
Not C – b/c this doesn’t address local storage constraints
not D – b/c this doesn’t address local storage constraints

Agree – off-site backup and low-latency.

Yes, I agree with McEphine. It’s option A.

The correct answer is D because the a backup is done only in Gateway-Virtual Tape Library and you don’t want your backup in a S3 bucket because that wouldn’t be cost effective.

Correct answer is A. Please read the documentation link by @McEphine and come back to the question.
Keywords: “growing at 500 GB a year and must be presented as a single logical volume.”;”while maintaining low-latency access to their frequently accessed data.” all that points to cached volume option of AWS storage Gateway.
