AWS Certified Solutions Architect – Associate (SAA-C03) — Question 785

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 designed to optimize the path from global users to applications on AWS by routing traffic over the AWS global network, which effectively accelerates TCP and UDP traffic such as RTMP streams. Amazon CloudFront is primarily a content delivery network for caching HTTP/HTTPS content and does not accelerate non-HTTP TCP ingest traffic like RTMP. AWS Client VPN and standard EC2 Elastic IPs do not offer global network routing optimization to improve connection speeds for remote users.
