AWS Certified Solutions Architect – Associate (SAA-C03) — Question 769
An online gaming company hosts its platform on Amazon EC2 instances behind Network Load Balancers (NLBs) across multiple AWS Regions. The NLBs can route requests to targets over the internet. The company wants to improve the customer playing experience by reducing end-to-end load time for its global customer base.
Which solution will meet these requirements?
Answer options
- A. Create Application Load Balancers (ALBs) in each Region to replace the existing NLBs. Register the existing EC2 instances as targets for the ALBs in each Region.
- B. Configure Amazon Route 53 to route equally weighted traffic to the NLBs in each Region.
- C. Create additional NLBs and EC2 instances in other Regions where the company has large customer bases.
- D. Create a standard accelerator in AWS Global Accelerator. Configure the existing NLBs as target endpoints.
Correct answer: D
Explanation
AWS Global Accelerator optimizes routing by directing user traffic over the AWS global network infrastructure directly to regional endpoints like Network Load Balancers (NLBs), significantly reducing latency for global users. Replacing NLBs with ALBs or using equally weighted Route 53 routing does not address global network path optimization. Deploying additional infrastructure in other regions manually increases administrative overhead and does not offer the automated, low-latency entry points provided by Global Accelerator.
