AWS Certified Solutions Architect – Associate (SAA-C02) — Question 503

A news company that has reporters all over the world is hosting its broadcast system on AWS. The reporters send live broadcasts to the broadcast system. The reporters use software on their phones to send live streams through the Real Time Messaging Protocol (RTMP).
A solutions architect must design a solution that gives the reporters the ability to send the highest quality streams. The solution must provide accelerated TCP connections back to the broadcast system.
What should the solutions architect use to meet these requirements?

Answer options

• A. Amazon CloudFront
• B. AWS Global Accelerator
• C. AWS Client VPN
• D. Amazon EC2 instances and AWS Elastic IP addresses

Correct answer: B

Explanation

AWS Global Accelerator is the ideal choice because it provides static IP addresses that act as a fixed entry point to your application endpoints, routing traffic over the congestion-free AWS global network to optimize TCP performance for protocols like RTMP. Amazon CloudFront is optimized for HTTP/HTTPS content delivery and caching, making it unsuitable for accelerating non-HTTP RTMP upload streams. Neither AWS Client VPN nor standard EC2 instances with Elastic IP addresses provide the global network path optimization required to accelerate ingest traffic from worldwide locations.
