Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 530 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Associate SAA-C03
Question #: 530
Topic #: 1
[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

A company has an online gaming application that has TCP and UDP multiplayer gaming capabilities. The company uses Amazon Route 53 to point the application traffic to multiple Network Load Balancers (NLBs) in different AWS Regions. The company needs to improve application performance and decrease latency for the online game in preparation for user growth.

Which solution will meet these requirements?

  • A. Add an Amazon CloudFront distribution in front of the NLBs. Increase the Cache-Control max-age parameter.
  • B. Replace the NLBs with Application Load Balancers (ALBs). Configure Route 53 to use latency-based routing.
  • C. Add AWS Global Accelerator in front of the NLBs. Configure a Global Accelerator endpoint to use the correct listener ports.
  • D. Add an Amazon API Gateway endpoint behind the NLBs. Enable API caching. Override method caching for the different stages.

Selected Answer: C
The key considerations are: The application uses TCP and UDP for multiplayer gaming, so Network Load Balancers (NLBs) are appropriate. AWS Global Accelerator can be added in front of the NLBs to improve performance and reduce latency by intelligently routing traffic across AWS Regions and Availability Zones. Global Accelerator provides static anycast IP addresses that act as a fixed entry point to application endpoints in the optimal AWS location. This improves availability and reduces latency. The Global Accelerator endpoint can be configured with the correct NLB listener ports for TCP and UDP.

Selected Answer: C
A: CloudFront is for caching. Not required B: ALB is for HTTP layer, won't help with TCP UDP issues D: API Gateway, API Caching total rubbish, ignore this option C: Is correct as Global Accelerator uses unicast for reducing latency globbally.

UDP and TCP is AWS Global accelarator as it works in the Transportation layer. Now this with NLB is perfect.
