Topic 1 Question 113
A company hosts an application on an Amazon EC2 instance in a single AWS Region. The application requires support for non-HTTP TCP traffic and HTTP traffic. The company wants to deliver content with low latency by leveraging the AWS network. The company also wants to implement an Auto Scaling group with an Elastic Load Balancer. How should a SysOps administrator meet these requirements?
Create an Auto Scaling group with an Application Load Balancer (ALB). Add an Amazon CloudFront distribution with the ALB as the origin.
Create an Auto Scaling group with an Application Load Balancer (ALB). Add an accelerator with AWS Global Accelerator with the ALB as an endpoint.
Create an Auto Scaling group with a Network Load Balancer (NLB). Add an Amazon CloudFront distribution with the NLB as the origin.

It is not A or B because ALB works with layer 7 of OSI model ( HTTP, HTTPS ) , NLB works with layer 4 ( TCP, UDP, TLS ) . it remains C or D . it is possible to have the eLB as the origin Cloudfront but CloudFront is designed to handle the HTTP protocol, while Global Accelerator is best used for HTTP and non-HTTP protocols such as TCP and UDP. So, my answer is D too.

In my opinion every answer so far is wrong. The question states it needs HTTP and NON-HTTP TCP tarffic. Therefore it cannot be an ALB and must be a NLB. AWS Global Accelerator: "When the internet is congested, AWS Global Accelerator optimizes the path to your application to keep packet loss, jitter, and latency consistently low."
D is correct in my world.
