Typical use case for AWS Global Accelerator.

Key words: "Reduce Internet latency" and "Exposing public static IP addresses" Ans: A. GA acts as single point of entry for internet based applications and use AWS back bone network therefore reducing latency across the globe.

R53 Latency based routing spends more time on the Internet legs and less on the AWS side.

Agree with A

A. Set up AWS Global Accelerator and add endpoints.

AWS Global Accelerator is a service in which you create accelerators to improve availability and performance of your applications for local and global users. Global Accelerator directs traffic to optimal endpoints over the AWS global network. This improves the availability and performance of your internet applications that are used by a global audience. Global Accelerator is a global service that supports endpoints in multiple AWS Regions, which are listed in the AWS Region Table. By default, Global Accelerator provides you with two static IP addresses that you associate with your accelerator. (Or, instead of using the IP addresses that Global Accelerator provides, you can configure these entry points to be IPv4 addresses from your own IP address ranges that you bring to Global Accelerator.)

A When the internet is congested, AWS Global Accelerator optimizes the path to your application to keep packet loss, jitter, and latency consistently low.

When the internet is congested, Global Accelerator’s automatic routing optimizations will help keep your packet loss, jitter, and latency consistently low. With Global Accelerator, you are provided two global static customer facing IPs to simplify traffic management. On the back end, add or remove your AWS application origins, such as Network Load Balancers, Application Load Balancers, Elastic IPs, and EC2 Instances, without making user facing changes. To mitigate endpoint failure, Global Accelerator automatically re-routes your traffic to your nearest healthy available endpoint." Answer A

IT could have been CF but only for static IP address it is GA A for sure

it's A

Ans = A static Ip=Global Accelerator

A right

Anycast IP means the same IP address used in multiple computers. based on the request regions it transferred to a nearest IP address.

Static anycast IP addresses AWS Global Accelerator provides you with static IP addresses that serve as a fixed entry point to your applications hosted in one or more AWS Regions. These IP addresses are anycast from AWS edge locations, so they’re announced from multiple AWS edge locations at the same time. This enables traffic to ingress onto the AWS global network as close to your users as possible

DAX is used when an application is deployed in one region, here we have multi region deploy instead

Ans is A

Answer: A
