Q40 — AWS SAA-C03 Ch.6

Question 40 of 65 | ← Chapter 6

Q405. 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. ✓
• 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
• D. Deploy a NAT instance that is configured with port forwarding to the EC2 instances in the Auto Scaling group

Correct Answer: A. Attach a Network Load Balancer to the Auto Scaling group.

Explanation

To meet the requirements of scaling out and in as traffic increases and decreases for a gaming application that transmits data using UDP packets, a solutions architect should attach a Network Load Balancer (NLB) to the Auto Scaling group.Network Load Balancer is specifically designed to handle high volumes of traffic and provide ultra-low latency for UDP-based applications. By attaching an NLB to the Auto Scaling group, incoming traffic can be evenly distributed across multiple EC2 instances, allowing for scalability and high availability. The NLB automatically scales with the traffic load, ensuring that the application can handle increased traffic and scale in when the traffic decreases.Option B (Attaching an Application Load Balancer) is not suitable for UDP-based applications as it is designed for HTTP and HTTPS traffic.Option C (Deploying an Amazon Route 53 record set with a weighted policy) is not directly related to scaling out and in as traffic increases and decreases.Option D (Deploying a NAT instance with port forwarding) is not necessary for handling UDP traffic and scaling the application.
