A company wants to improve the availability and performance of its stateless UDP-based workload. The workload is deployed on Amazon EC2 instances in multiple AWS Regions. What should a solutions architect recommend to accomplish this?
A.
Place the EC2 instances behind Network Load Balancers (NLBs) in each Region. Create an accelerator using AWS Global Accelerator. Use the NLBs as endpoints for the accelerator.
B.
Place the EC2 instances behind Application Load Balancers (ALBs) in each Region. Create an accelerator using AWS Global Accelerator. Use the ALBs as endpoints for the accelerator.
C.
Place the EC2 instances behind Network Load Balancers (NLBs) in each Region. Create an Amazon CloudFront distribution with an origin that uses Amazon Route 53 latency-based routing to route requests to the NLBs.
D.

If the moderator were to update with the correct suggested answer, then there are tons of questions for him to work on liao. I do have the feeling that it is not easy to derive an accurate answer for the not-so-straight-forward questions. Let's pray.
How come there are so many wrong answers from other brain dumps. It is worthless if there was no discussion section here.
If it is not D then I have no i deal of what I am studying.
CloudFront is designed to handle HTTP protocol meanwhile Global Accelerator is best used for both HTTP and non-HTTP protocols such as TCP and UDP.
I also would go A.
