Which algorithm routes incoming traffic to the server with the fewest active connections?

• A. Round Robin
• B. IP Hash
• C. Least Connectivity
• D. Weighted Round Robin

Answer: (C)

The algorithm that routes incoming traffic to the server with the fewest active connections is designed to optimize resource utilization and improve response times. This approach is often referred to as Least Connectivity. Least Connectivity operates by continuously monitoring the number of active connections to each server and directing new incoming connections to the server that currently has the least number of active connections. This method helps ensure that no single server is overwhelmed with traffic while others may be underutilized. By balancing the load this way, the algorithm can enhance the overall performance of the server cluster and improve user experience. In contrast, other algorithms, such as Round Robin, distribute requests evenly in a cyclical manner without consideration of the current load on each server. IP Hash relies on the client's IP address to consistently route traffic to the same server, which can lead to uneven load if some clients generate more connections than others. Weighted Round Robin assigns a predetermined weight to each server based on its capacity, but still does not take the current number of active connections into account. Thus, Least Connectivity stands out as the most effective method for dynamic load balancing based on real-time server load.
