Which of the following protocols is supported by a Load Balancer?

• A. HTTP/3
• B. SSH
• C. HTTP/1.1
• D. FTP

Answer: (C)

Load balancers are designed to manage and distribute incoming network traffic across multiple servers to ensure reliability and performance. Among the options provided, HTTP/1.1 is a fundamental protocol widely implemented in web traffic management. It allows the load balancer to efficiently route HTTP requests to various back-end servers based on different algorithms, like round-robin or least connections. HTTP/1.1 supports additional features like persistent connections, chunked transfer encoding, and status codes, which make it well-suited for the web ecosystem. Given its universality and vital role in web communication, it is a core protocol supported by load balancers. The other protocols mentioned, while they may be used in specific contexts, do not have the same level of integration with load balancers in general web traffic scenarios. HTTP/3 is the newer version and is still being adopted widely. SSH is primarily used for secure shell access, not for load balancing web traffic, while FTP is mostly used for file transfers, which may not necessitate load balancing in the same way that HTTP traffic does.
