What is the main role of a load balancer in a networked application deployment?

Options:

Distribute incoming network requests across multiple servers to improve availability and throughput
Encrypt traffic between clients and servers using symmetric keys
Store backups of application state for disaster recovery
Translate domain names to IP addresses for clients

Correct answer: Distribute incoming network requests across multiple servers to improve availability and throughput

Explanation: A load balancer spreads incoming requests across multiple backend servers to increase availability and throughput and to avoid single-server overload. It commonly operates at OSI layer 4 (transport) or layer 7 (application).
