Amazon ANS-C01 Exam - 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.

I think D could be more reliable with the accelerator, though.

I'm surprised they can't use DNS at all. That's a big limitation!

Wait, why not use Global Accelerator? Seems like a missed opportunity.

I recall that using an Auto Scaling group with NLB is a common pattern for IoT applications. I think option C might be the best fit.

I’m a bit confused about the Global Accelerator. Does it really add value if the IoT devices can't resolve DNS?

I think we practiced a similar question where we had to choose between ALB and NLB. I feel like NLB is the right choice since it handles IP addresses directly.

I remember something about using NLBs for high performance, but I'm not sure if it's the most cost-effective option here.

This is a tricky one, but I think I've got a handle on it. I'm leaning towards option D - the AWS Global Accelerator with the NLB endpoint. That should provide the scalability and IP-based connectivity the IoT devices need.

Okay, I'm a bit confused by the differences between the Network Load Balancer and the Application Load Balancer. I'll need to review the details of each to figure out which one is the better choice.

Hmm, the key here seems to be that the IoT devices can't use DNS resolution. I think options B and D that use the AWS Global Accelerator might be the way to go.

Okay, let me think this through step-by-step. Run lines are used to indicate the slope of a straight run, and the color is important for visualizing the slope. I believe the correct answer is B, black, but I'll review my notes to confirm.

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.
