Global accelerator works on TCP tier. ClouldFront is a CDN and will not improve performance for RTMP cause it need real time delivery.

You need AWS global network for shorter optimized paths, you can't rely on Internet and ISPs. B is the correct answer to me.

B can't an Answer. RTMP is statefull protocol served by RTMP stream server. On streaming, client must keep the connection with the Stream server. It must not be changed . But Global Accelerator is a balancer for only stateless requests.

This is the kind of question that you don't know if you have to answer about how it used to be or how it is working now. CloudFront was capable of performing RTMP distributions and this option is marked a correct in other websites. BUT AWS deprecated this capability in CloudFront so now the proper answer cannot be CloudFront (ouch!) https://thestack.technology/cloudfront-rtmp-adobe-flash-media-server/ https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/WhatsNew.html

Correct answer is B. AWS Global Accelerator Question is asking "enables reporters to deliver the highest-quality streams possible" (Global Acceleator), not to enable viewer to receive highest quality stream (CloudFront)

A - An Amazon CloudFront distribution is configured to use the MediaStore custom endpoints as its origin. The CloudFront distribution delivers your live stream to viewers with low latency and high transfer speeds. https://aws.amazon.com/solutions/implementations/live-streaming-on-aws/

" The reporters transmit live broadcasts through the Real Time Messaging Protocol using software installed on their phones (RTMP)". (They do not use MediaStore or any other aws service to send live streams) Therefore the answer should be B

Global Accelerator is a good fit for non-HTTP use cases, such as gaming (UDP), IoT (MQTT), or Voice over IP, as well as for HTTP use cases that specifically require static IP addresses or deterministic, fast regional failover.

Selected Answer: B
AWS Global Accelerator and Amazon CloudFront are separate services that use the AWS global network and its edge locations around the world. CloudFront improves performance for both cacheable content (such as images and videos) and dynamic content (such as API acceleration and dynamic site delivery). Global Accelerator improves performance for a wide range of applications over TCP or UDP by proxying packets at the edge to applications running in one or more AWS Regions. Global Accelerator is a good fit for non-HTTP use cases, such as gaming (UDP), IoT (MQTT), or Voice over IP, as well as for HTTP use cases that specifically require static IP addresses or deterministic, fast regional failover. https://aws.amazon.com/global-accelerator/faqs/
