Amazon ANS-C01 Exam - Topic 1 Question 6 Discussion

Actual exam question for Amazon's ANS-C01 exam

Question #: 6
Topic #: 1

An IoT company sells hardware sensor modules that periodically send out temperature, humidity, pressure, and location data through the MQTT messaging protocol. The hardware sensor modules send this data to the company's on-premises MQTT brokers that run on Linux servers behind a load balancer. The hardware sensor modules have been hardcoded with public IP addresses to reach the brokers.

The company is growing and is acquiring customers across the world. The existing solution can no longer scale and is introducing additional latency because of the company's global presence. As a result, the company decides to migrate its entire infrastructure from on premises to the AWS Cloud. The company needs to migrate without reconfiguring the hardware sensor modules that are already deployed across the world. The solution also must minimize latency.

The company migrates the MQTT brokers to run on Amazon EC2 instances.

What should the company do next to meet these requirements?

APlace the EC2 instances behind a Network Load Balancer (NLB). Configure TCP listeners. Use Bring Your Own IP (BYOIP) from the on-premises network with the NLB.

BPlace the EC2 instances behind a Network Load Balancer (NLB). Configure TCP listeners. Create an AWS Global Accelerator accelerator in front of the NLUse Bring Your Own IP (BYOIP) from the on-premises network with Global Accelerator.

CPlace the EC2 instances behind an Application Load Balancer (ALB). Configure TCP listeners. Create an AWS Global Accelerator accelerator in front of the ALB. Use Bring Your Own IP (BYOIP) from the on-premises network with Global Accelerator

DPlace the EC2 instances behind an Amazon CloudFront distribution. Use Bring Your Own IP (BYOIP) from the on-premises network with CloudFront.

Not sure if Global Accelerator is really necessary here.

BYOIP is a must for this migration, no doubt about that.

Surprised they didn't consider using CloudFront at all!

I think A is better since it uses NLB directly.

Option B seems solid for minimizing latency with Global Accelerator.

I’m leaning towards option B because it seems to address both the latency and the need for a stable IP, but I’m not entirely confident about the specifics of Global Accelerator.

I practiced a similar question, and I feel like placing EC2 instances behind an NLB with Global Accelerator makes sense, but I’m a bit confused about the IP configuration part.

I think Global Accelerator could help reduce latency, but I can't recall if it works better with NLB or ALB for this scenario.

I remember we discussed how using a Network Load Balancer is crucial for TCP traffic, but I'm not sure if BYOIP is the best option here.

I vaguely remember that CloudFront is more for content delivery, so I don't think it fits this use case, but I’m not entirely sure.

I practiced a similar question about load balancing and IP management, and I feel like BYOIP is crucial for this scenario, but I’m confused about which load balancer to use.

I remember we discussed the importance of minimizing latency for global applications, but I'm not sure if the Network Load Balancer is the best choice here.

Okay, I remember learning about this in class. Symmetric keys are the same for encryption and decryption, while asymmetric keys come in public-private pairs. I think the answer is A.

Hmm, this looks like a tricky one. I'll need to carefully consider the options and think through the characteristics of each type of cloud hard disk.

Hmm, this seems like a straightforward question about updating the price book on an opportunity. I think I know the answer, but I'll double-check the options just to be sure.
