A company wants to run a gaming application on Amazon EC2 instances that are part of an Auto Scaling group in the AWS Cloud. The application will transmit data by using UDP packets. The company wants to ensure that the application can scale out and in as traffic increases and decreases.

What should a solutions architect do to meet these requirements?

A.
Attach a Network Load Balancer to the Auto Scaling group
Answers
A.

B.
Attach an Application Load Balancer to the Auto Scaling group.
Answers
B.
Attach an Application Load Balancer to the Auto Scaling group.
C.
Deploy an Amazon Route 53 record set with a weighted policy to route traffic appropriately
Answers
C.
Deploy an Amazon Route 53 record set with a weighted policy to route traffic appropriately
D.
Deploy a NAT instance that is configured with port forwarding to the EC2 instances in the Auto Scaling group.
Answers
D.
Deploy a NAT instance that is configured with port forwarding to the EC2 instances in the Auto Scaling group.
Suggested answer: A

Explanation:

This solution meets the requirements of running a gaming application that transmits data by using UDP packets and scaling out and in as traffic increases and decreases. A Network Load Balancer can handle millions of requests per second while maintaining high throughput at ultra low latency, and it supports both TCP and UDP protocols. An Auto Scaling group can automatically adjust the number of EC2 instances based on the demand and the scaling policies. Option B is incorrect because an Application Load Balancer does not support UDP protocol, only HTTP and HTTPS. Option C is incorrect because Amazon Route 53 is a DNS service that can route traffic based on different policies, but it does not provide load balancing or scaling capabilities. Option D is incorrect because a NAT instance is used to enable instances in a private subnet to connect to the internet or other AWS services, but it does not provide load balancing or scaling capabilities. https://aws.amazon.com/blogs/aws/new-udp-load-balancing-for-network-load-balancer/ https://docs.aws.amazon.com/autoscaling/ec2/userguide/AutoScalingGroup.html
