Storage Gateway Quiz
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 500GB 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 offsite 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
A. Gateway-Cached Volumes with snapshots scheduled to Amazon S3
Gateway-cached volumes let you use Amazon Simple Storage Service (Amazon S3) as your primary data storage while retaining frequently accessed data locally in your storage gateway. Gateway-cached volumes minimize the need to scale your on-premises storage infrastructure, while still providing your applications with low-latency access to their frequently accessed data. You can create storage volumes up to 32 TiB in size and attach to them as iSCSI devices from your on-premises application servers. Your gateway stores data that you write to these volumes in Amazon S3 and retains recently read data in your on-premises storage gateway’s cache and upload buffer storage.
