Answer: Configure 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., Configure 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.
To meet the requirements of providing low latency for users across several countries in Europe, identifying users’ IP addresses for localized content, and implementing a failover mechanism that works for both GET and POST methods with a failover time of less than 1 minute, the best solution is to use AWS Global Accelerator. AWS Global Accelerator improves the availability and performance of your applications with local or global users. It provides static IP addresses that act as a fixed entry point to your application endpoints in a single or multiple AWS Regions. Global Accelerator directs traffic to optimal endpoints based on health, geographic location, and routing policies that you configure. This ensures that your application is highly available and performs well for your users. Option A suggests configuring a Network Load Balancer (NLB) in each environment in the new AWS Regions and creating an AWS Global Accelerator accelerator with endpoint groups pointing to the NLBs. This solution is correct because NLBs are capable of handling millions of requests per second while maintaining ultra-low latencies, and AWS Global Accelerator can direct traffic to the optimal NLB based on health checks and geographic location, ensuring low latency and high availability. Option B, which suggests using Application Load Balancers (ALBs) instead of NLBs, is also correct because ALBs can also be used with AWS Global Accelerator to achieve similar outcomes, especially for HTTP/HTTPS traffic. ALBs offer advanced routing features based on content, which can be beneficial for applications requiring localized content based on users’ geographic location. Therefore, both options A and B are correct as they both utilize AWS Global Accelerator to meet the requirements of low latency, localized content delivery, and fast failover.

An online retail company operates a web application in the us-west-2 Region, serving users in the United States. The company aims to expand into multiple European countries and ensure low-latency access for all users. The application must identify users' IP addresses to deliver localized content based on their geographic location and relies on HTTP GET and POST methods for functionality. Additionally, the company requires a failover mechanism for both GET and POST methods, based on health checks, with failover occurring in under 1 minute for all clients.
Which solution meets these requirements?
A
Configure 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.
B
Configure 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.
C
Configure 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.
D
Configure 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.
