SAA-C03 Question 233
Single answerA company operates a hybrid environment with on-premises infrastructure and AWS Cloud services. They need a storage solution that allows their on-premises applications to access frequently used data with low latency while securely archiving infrequently accessed data to Amazon S3. Which solution best meets these requirements?
- A
Use AWS Storage Gateway with the File Gateway configuration to provide low-latency access to frequently used files and automatic tiering to Amazon S3 for archival storage.
- B
Use AWS DataSync to transfer files between the on-premises environment and Amazon S3, and configure lifecycle policies in S3 to manage archival data.
- C
Use Amazon FSx for Windows File Server to provide on-premises low-latency access and enable S3 lifecycle rules to move old data to archival storage.
- D
Use Amazon EBS volumes mounted to on-premises servers over a Direct Connect link for low-latency access and archive the data to S3 Glacier using AWS Backup.
Show answer and explanation
Correct answer: A
Explanation
The AWS Storage Gateway in File Gateway configuration is specifically designed for hybrid storage architectures where low-latency access to active data is required on-premises, while securely archiving older data to Amazon S3. It enables seamless integration between on-premises applications and AWS storage, meeting the business requirements for this scenario.
- A. Correct.
This option is correct. AWS Storage Gateway in File Gateway configuration provides seamless access to frequently used files via NFS or SMB protocols, and automatically transfers infrequently accessed data to Amazon S3 for archival. It meets the requirement for low-latency access and secure archival.
- B. Incorrect.
This option is incorrect. AWS DataSync is designed for large-scale data transfers between on-premises and AWS. It doesn't provide low-latency access to frequently used data, as it involves batch-based data transfers rather than real-time access.
- C. Incorrect.
This option is incorrect. Amazon FSx for Windows File Server is a fully managed service for Windows-based file storage in the cloud. It doesn't integrate seamlessly with on-premises environments for low-latency access in hybrid setups.
- D. Incorrect.
This option is incorrect. Amazon EBS volumes are not designed for use in on-premises environments. While Direct Connect provides a high-speed connection, using EBS for low-latency access from on-premises is not a valid architecture.
