SAA-C03 Question 231
Single answerA company operates a hybrid cloud environment and wants to ensure low-latency access to frequently accessed data for its on-premises applications while seamlessly integrating with AWS. The company also wants to offload infrequently accessed data to AWS to reduce local storage costs. Which solution would best meet these requirements?
- A
Use AWS Storage Gateway in File Gateway mode to cache frequently accessed data on-premises and store infrequent data in Amazon S3.
- B
Use Amazon FSx for Windows File Server to provide low-latency access to on-premises applications and back up data to Amazon S3 Glacier.
- C
Use AWS DataSync to replicate data between on-premises storage and Amazon EFS for low-latency access.
- D
Use Amazon S3 with Transfer Acceleration to provide low-latency access for on-premises applications.
Show answer and explanation
Correct answer: A
Explanation
The AWS Storage Gateway in File Gateway mode is the best solution for hybrid storage requirements where frequently accessed data needs to be cached locally for low-latency access, and infrequent data is stored cost-effectively in Amazon S3. It seamlessly integrates on-premises environments with AWS storage services, meeting the business requirements outlined.
- A. Correct.
Correct. AWS Storage Gateway in File Gateway mode provides a hybrid storage solution where frequently accessed data can be cached locally for low-latency access, while infrequently accessed data is stored in Amazon S3.
- B. Incorrect.
Incorrect. Amazon FSx for Windows File Server is a fully managed file system in AWS, but it does not provide on-premises caching or hybrid storage capabilities.
- C. Incorrect.
Incorrect. AWS DataSync is primarily used for data transfer and replication but does not provide low-latency local caching for on-premises applications.
- D. Incorrect.
Incorrect. Amazon S3 with Transfer Acceleration improves data transfer speeds over large geographic distances but does not provide low-latency access or caching for on-premises applications.
