Correct answer: C
Explanation
AWS Storage Gateway - File Gateway is specifically designed to enable low-latency access to frequently accessed data on-premises by caching this data locally while seamlessly storing the full dataset in Amazon S3. This makes it the most suitable service for the given scenario.
- A. Incorrect.
Amazon EFS is a fully managed file system designed for Linux-based workloads. However, it is not specifically designed to provide cached access for on-premises applications.
- B. Incorrect.
Amazon S3 Glacier is an archival storage service optimized for infrequent access and long-term storage. It is unsuitable for providing low-latency, cached file system access.
- C. Correct.
AWS Storage Gateway - File Gateway provides local caching functionality, allowing frequently accessed data to be cached on-premises while the full dataset resides in Amazon S3. This meets the company's requirements.
- D. Incorrect.
Amazon FSx for Windows File Server is designed for fully managed Windows file systems in the cloud but does not offer a cached file system for on-premises applications.
