AWS Certified Solutions Architect – Associate (SAA-C02) — Question 56

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 steaming?

Answer options

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

Correct answer: A

Explanation

Amazon CloudFront is a content delivery network (CDN) that caches content at various edge locations globally, which helps reduce latency for both real-time and on-demand video streaming. AWS Global Accelerator primarily improves availability and performance for applications, but does not specifically optimize video streaming. Amazon Route S3 is not a valid service, and Amazon S3 Transfer Acceleration is designed for speeding up uploads to S3, rather than enhancing streaming performance.
