A is right You can use CloudFront to deliver video on demand (VOD) or live streaming video using any HTTP origin 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

A because CloudFront can be used for video streaming. NOT GA because GA is good for services with lower level network protocols - and their speed ups.

Selected Answer: B
Option A (Amazon CloudFront) is a content delivery network (CDN) service that can improve the performance of on-demand streaming by caching and delivering content from edge locations. While it can accelerate on-demand streaming, it may not provide the same level of optimization for real-time streaming as AWS Global Accelerator.

Selected Answer: A
https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/on-demand-streaming-video.html CloudFront solves the problem of streaming over Amazon CDN on global scale. "B" AWS Global Accelerator won't be suitable for streaming from web server as it does not provide edge caching like CDN. Global Accelerator only points the user to nearest functioning node which is helpful for real-time streaming but not best for on-demand.

A IS THE RIGHT ANS . Amazon CloudFront is a content delivery network (CDN) service offered by AWS. It is designed to deliver data, including videos and other media files, with low latency and high transfer speeds. This is a suitable option for optimizing website performance, especially for streaming content globally.

Selected Answer: B
Although CloudFront is a content delivery network (CDN) that can provide low-latency and high-performance content delivery, its performance for real-time streaming and on-demand streaming may not be as professional as AWS Global Accelerator

https://aws.amazon.com/global-accelerator/ "AWS Global Accelerator is a networking service that helps you improve the availability, performance, and security of your public applications. Global Accelerator provides two global static public IPs that act as a fixed entry point to your application endpoints, such as Application Load Balancers, Network Load Balancers, Amazon Elastic Compute Cloud (EC2) instances, and elastic IPs." It is Anycast which connect user to closest resource on your server like ALB etc or ergional services. CloudFront is CDN and pushes your content to edge locations near the user. This solves all issues of latency and performance

Selected Answer: A
CloudFront offers several options for streaming your media to global viewers—both pre-recorded files and live events. https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/IntroductionUseCases.html#IntroductionUseCasesStreaming For video on demand (VOD) streaming, you can use CloudFront to stream in common formats such as MPEG DASH, Apple HLS, Microsoft Smooth Streaming, and CMAF, to any device. For broadcasting a live stream, you can cache media fragments at the edge, so that multiple requests for the manifest file that delivers the fragments in the right order can be combined, to reduce the load on your origin server.
