AWS Certified Solutions Architect – Associate (SAA-C03) — Question 156

A solutions architect is optimizing a website for an upcoming musical event. Videos of the performances will be streamed in real time and then will be available on demand. The event is expected to attract a global online audience.

Which service will improve the performance of both the real-time and on-demand streaming?

Answer options

• A. Amazon CloudFront
• B. AWS Global Accelerator
• C. Amazon Route 53
• D. Amazon S3 Transfer Acceleration

Correct answer: A

Explanation

Amazon CloudFront is a content delivery network (CDN) that caches content at edge locations, thereby reducing latency for both real-time and on-demand streaming. AWS Global Accelerator improves the availability and performance of your applications but does not specifically optimize streaming. Amazon Route 53 is a DNS service and does not directly enhance streaming performance. Amazon S3 Transfer Acceleration speeds up uploads to S3 but is not focused on streaming content.
