AWS Certified Solutions Architect Associate SAA-C03 Practice Question
A financial institution requires an archiving solution for critical data stored on local file servers. The data must be accessible with minimal delay when requested by on-premises users, yet older, less frequently accessed files should be economically archived in the cloud. However, after a specific period of inactivity, these older files should be transitioned to a less expensive storage class. Which solution should the architect recommend to meet these needs in a cost-efficient manner?
File gateway mode of a certain hybrid storage service
An online data transfer service
A managed file transfer service
A fully managed file storage service for Windows files
File gateway mode of a certain hybrid storage service provides a seamless way to integrate on-premises file systems with cloud storage like Amazon S3, ensuring low-latency access via local caching. It also offers automatic tiering capabilities to transition data to cost-saving storage classes after set periods of inactivity. This makes it a suitable solution for the financial institution's requirements. The alternatives mentioned do not offer the same combined functionality regarding local caching, seamless integration with cloud storage, and automatic tiering based on inactivity, thus, they would not present the most efficient solution for the given scenario.
