AWS Certified SysOps Administrator – Associate (legacy) — Question 705

A company needs to have real-time access to image data while seamlessly maintaining a copy of the images in an offsite location for disaster recovery purposes.
Which solution meets the requirement?

Answer options

• A. Create an AWS Storage Gateway volume gateway configured as a stored volume. Mount it from clients using Internet Small Computer System Interface (iSCSI).
• B. Mount an Amazon EFS volume on a local server. Share this volume with employees who need access to the images.
• C. Store the images in Amazon S3, and use AWS Data Pipeline to allow for caching of S3 data on local workstations.
• D. Use Amazon S3 for file storage, and enable S3 Transfer Acceleration to maintain a cache for frequently used files to increase local performance.

Correct answer: D

Explanation

Using Amazon S3 provides a highly durable, offsite repository for disaster recovery, ensuring that image data is safely replicated in the cloud. Enabling S3 Transfer Acceleration utilizes AWS Edge Locations to optimize transfer speeds, allowing users to experience fast, real-time access to the files. Other alternatives, such as mounting Amazon EFS locally or using AWS Data Pipeline for workstation caching, do not provide a viable or architecturally sound solution for this scenario.
