Amazon ANS-C01 Exam - Topic 4 Question 60 Discussion

Actual exam question for Amazon's ANS-C01 exam

Question #: 60
Topic #: 4

An online retail company is running a web application in the us-west-2 Region and serves consumers in the United States. The company plans to expand across several countries in Europe and wants to provide low latency for all its users.

The application needs to identify the users' IP addresses and provide localized content based on the users' geographic location. The application uses HTTP GET and POST methods for its functionality. The company also needs to develop a failover mechanism that works for GET and POST methods and is based on health checks. The failover must occur in less than 1 minute for all clients.

Which solution will meet these requirements?

AConfigure a Network Load Balancer (NLB) for the application in each environment In the new AWS Regions. Create an AWS Global Accelerator accelerator that has endpoint groups that point to the NLBs in each Region.

DConfigure a Network Load Balancer (NLB) for the application in each environment in the new AWS Regions. Create an Amazon CloudFront distribution. Configure an origin group with origin failover options.

BConfigure an Application Load Balancer (ALB) for the application in each environment in the new AWS Regions. Create an AWS Global Accelerator accelerator that has endpoint groups that point to the ALBs in each Region.

CConfigure an Application Load Balancer (ALB) for the application in each environment in the new AWS Regions. Create Amazon Route 53 public hosted zones that have failover routing policies.

A CDN, huh? I bet the Europeans will love getting their content delivered with a side of maple syrup and poutine!

The CDN idea sounds good, but I'm curious about the failover mechanism. How would that work with a CDN?

I'm not sure a CDN is the best solution here. What about using a load balancer with health checks instead?

Agreed, a CDN is the way to go. It'll also help with the failover mechanism for both GET and POST requests.

Definitely go with a Content Delivery Network (CDN) to handle the geographic expansion and low latency requirements.

I believe we should consider using Elastic Load Balancing with health checks, but I'm not clear on how to ensure the failover happens in under a minute.

I’m a bit confused about how to handle the localized content based on IP addresses. I think we might need a geolocation service, but I can't recall the specifics.

This question seems similar to one we practiced on load balancing and failover strategies. I think using Route 53 for DNS failover could be a part of the solution.

I remember studying about using AWS Global Accelerator for low latency, but I'm not sure how it integrates with health checks for failover.

This looks challenging, but I think a solution using CloudFront, Route 53, and potentially other AWS services like Application Load Balancer could work. I'd need to dig into the documentation to work out the details.

I'm a bit unsure about how to approach the failover aspect, especially for the POST requests. I'll need to review best practices for handling failover for different HTTP methods.

Okay, the key things I need to focus on are low latency for global users, identifying user locations, and a robust failover system. I'll need to research AWS services that can help with those requirements.

Hmm, this seems like a complex problem. I'd need to think through the details of how to implement the health checks and failover mechanism for both GET and POST requests.

I think I'd start by considering a multi-region architecture with CloudFront and Route 53 to handle the geographic distribution and failover requirements.
