SAA-C03 Question 414
Single answerA company has an on-premises file storage system that needs to be integrated with AWS to provide low-latency access to frequently used data and seamless access to the full dataset stored in Amazon S3. Which hybrid storage solution should they use to meet this requirement?
- A
AWS DataSync
- B
AWS Storage Gateway - File Gateway
- C
AWS Transfer Family
- D
Amazon S3 Glacier
Show answer and explanation
Correct answer: B
Explanation
AWS Storage Gateway - File Gateway is specifically designed for hybrid storage scenarios where low-latency access is required for frequently used data while providing seamless access to the full dataset stored in Amazon S3. It caches frequently accessed data locally, which meets the company’s requirements. Other options like AWS DataSync, AWS Transfer Family, and Amazon S3 Glacier serve different purposes and do not address the need for low-latency access or hybrid storage integration.
- A. Incorrect.
AWS DataSync is used for data transfer between on-premises storage and AWS, but it is not designed for low-latency access to data. It is more suitable for batch data migration or replication.
- B. Correct.
AWS Storage Gateway - File Gateway is the correct option because it provides a hybrid storage solution that allows on-premises applications to access data stored in Amazon S3 with low-latency local caching for frequently accessed data.
- C. Incorrect.
AWS Transfer Family is used for securely transferring files over protocols like SFTP, FTPS, and FTP to and from Amazon S3 or Amazon EFS. It is not designed for hybrid storage or low-latency access.
- D. Incorrect.
Amazon S3 Glacier is a deep archive storage solution designed for long-term, infrequently accessed data. It does not provide low-latency access or hybrid storage capabilities.
