AWS Certified Solutions Architect – Associate (SAA-C02) — Question 542

A large media company hosts a web application on AWS. The company wants to start caching confidential media files so that users around the world will have reliable access to the files. The content is stored in Amazon S3 buckets. The company must deliver the content quickly, regardless of where the requests originate geographically.
Which solution will meet these requirements?

Answer options

• A. Use AWS DataSync to connect the S3 buckets to the web application.
• B. Deploy AWS Global Accelerator to connect the S3 buckets to the web application.
• C. Deploy Amazon CloudFront to connect the S3 buckets to CloudFront edge servers.
• D. Use Amazon Simple Queue Service (Amazon SQS) to connect the S3 buckets to the web application.

Correct answer: C

Explanation

Amazon CloudFront is a content delivery network (CDN) service that caches content at edge locations globally, allowing low-latency and secure delivery of media files stored in Amazon S3. AWS DataSync is designed for data migration and transfer, while AWS Global Accelerator optimizes network paths but does not cache content. Amazon SQS is a message queuing service and cannot be used for caching or delivering media files.
