Answer: Network Load Balancer

## Explanation **Network Load Balancer** is the correct answer because: - **Network Load Balancer (NLB)** operates at Layer 4 (Transport layer) of the OSI model - It can handle both **TCP** and **UDP** traffic - NLB is designed for high-performance, low-latency scenarios - It can handle millions of requests per second while maintaining ultra-low latencies **Why the other options are incorrect:** - **Amazon API Gateway**: Primarily handles HTTP/HTTPS traffic (Layer 7) for REST APIs and WebSocket connections - **Application Load Balancer (ALB)**: Operates at Layer 7 (Application layer) and only handles HTTP/HTTPS traffic - **Gateway Load Balancer**: Specialized for deploying, scaling, and managing third-party virtual appliances, but primarily handles IP traffic rather than specifically TCP/UDP distribution **Key Use Cases for Network Load Balancer:** - TCP/UDP-based applications - Gaming applications - IoT applications - Voice over IP (VoIP) - Real-time streaming applications
