You are working as a consultant for a construction firm. The architecture team saves all the artifacts related to the new construction works in an on-premises storage disk. Due to expansion & new project works in the last quarter, on-premises storage is getting exhausted.
The firm has a very limited budget for storage devices & not keen to invest further in storage. Upon further analysis, you found that the Architecture team usually works only on recent plans. CTO has enquired you to find the best possible storage option. Which of the following will meet the requirement?

Answer options:

A.Cached Volumes Gateway
B.File Gateway
C.Stored Volumes Gateway
D.Tape Gateways

Correct Answer: A
You store your data in Amazon Simple Storage Service (Amazon S3) and retain a copy of frequently accessed data subsets locally. Cached volumes offer 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.
Option B is incorrect as a file gateway supports a file interface into Amazon Simple Storage Service (Amazon S3) and combines service and a virtual software appliance. In the above scenario, this would not meet the requirement.
Option C is incorrect as the client is looking to save additional storage space. With Stored Volume Gateway, the entire dataset is locally stored on-premises gateway while asynchronously back up point-in-time snapshots of this data to Amazon S3.
Option D is incorrect as tape gateway provides a virtual tape infrastructure that scales seamlessly with your business needs and eliminates the operational burden of provisioning, scaling, and maintaining a physical tape infrastructure. In the above scenario, this would not meet the requirement.
