Amazon Exam ANS-C01 Topic 5 Question 37 Discussion

Actual exam question for Amazon's ANS-C01 exam

Question #: 37
Topic #: 5

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?

AUse an Application Load Balancer (ALB)-type target group for a Network Load Balancer (NLB). Create an EC2 Auto Scaling group. Attach the Auto Scaling group to the ALB. Set up the IoT devices to connect to the IP addresses of the NLB.

BUse an AWS Global Accelerator accelerator with an Application Load Balancer (ALB) endpoint. Create an EC2 Auto Scaling group. Attach the Auto Scaling group to the ALSet up the IoT devices to connect to the IP addresses of the accelerator.

CUse 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.

DUse an AWS Global Accelerator accelerator with a Network Load Balancer (NLB) endpoint. 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 accelerator.

Show Suggested Answer

Suggested Answer: D

AWS Global Accelerator can provide static IP addresses that the IoT devices can connect to without using DNS2.It can also route traffic over the AWS global network and improve performance and availability for the IoT devices2.An NLB can provide end-to-end encryption for HTTPS traffic by using TLS as a target group protocol and terminating SSL connections at the load balancer level1.An NLB can also support session affinity (sticky sessions) with TCP connections1.

Alright, let's get serious here. Option C is the way to go - NLB and Auto Scaling group. Simple, effective, and cost-conscious. Nailed it!

Yeah, using a Network Load Balancer with Auto Scaling group makes sense for this scenario.

Haha, maybe they should just tell the IoT devices to 'figure it out' and connect to the load balancer. No DNS? No problem!

Hmm, I don't know. The Global Accelerator might add some extra performance benefits. But you're right, it's probably overkill for this use case.

I'm with Lenora on this one. Option C seems like the way to go - keep it simple with the Network Load Balancer and Auto Scaling group.
