Question

A company is developing an application in which IoT devices will report measurements to the AWS Cloud. The application will have millions of end users. The company observes that the IoT devices cannot support DNS resolution. The company needs to implement an Amazon EC2 Auto Scaling solution so that the IoT devices can connect to an application endpoint without using DNS. Which solution will meet these requirements MOST cost-effectively?

Accepted Answer

Correct answer: C. The correct answer is C. Option C: Use a Network Load Balancer (NLB). Create an EC2 Auto Scaling group. Attach the Auto Scaling group to the NLB. Set up the IoT devices to connect to the IP addresses of the NLB. Auto Scaling adjusts capacity automatically to match demand, improving availability and cost efficiency. Amazon EC2 provides resizable virtual servers when you need full control of the operating system. A Network Load Balancer handles very high throughput TCP/UDP traffic with ultra-low latency and static IPs. This option delivers the requirement at the lowest cost.
