Answer: Use a Network Load Balancer for traffic distribution and Amazon DynamoDB on-demand for data storage.

## Explanation **Correct Answer: B** **Why Option B is correct:** 1. **Network Load Balancer (NLB) for UDP traffic**: The game uses UDP for communications, and NLB is specifically designed to handle Layer 4 traffic (TCP/UDP) at ultra-high performance. NLB preserves the source IP address and can handle millions of requests per second, making it ideal for real-time multiplayer games. 2. **Amazon DynamoDB on-demand for non-relational data**: The requirements specify: - Non-relational data storage (gamer scores) - Scale without intervention - Handle spikes in demand DynamoDB on-demand provides: - Automatic scaling with no capacity planning required - Pay-per-request pricing - Handles sudden traffic spikes seamlessly - Ideal for gaming leaderboards and score storage **Why other options are incorrect:** **Option A**: Amazon Route 53 is a DNS service, not suitable for real-time UDP traffic distribution to Auto Scaling groups. Aurora Serverless is a relational database, not suitable for non-relational data. **Option C**: While NLB is correct for UDP traffic, Aurora Global Database is a relational database solution and doesn't match the non-relational data requirement. **Option D**: Application Load Balancer (ALB) operates at Layer 7 (HTTP/HTTPS) and doesn't support UDP traffic, which is required for the game communications. **Key AWS Services Understanding:** - **NLB vs ALB**: NLB for Layer 4 (TCP/UDP), ALB for Layer 7 (HTTP/HTTPS) - **DynamoDB on-demand**: Auto-scaling NoSQL database with pay-per-request pricing - **Game architecture**: Real-time games typically use UDP for lower latency, and NLB is the appropriate load balancer choice
