A network engineer is configuring a device that distributes incoming web traffic evenly across several web servers. This is to ensure high availability and optimal resource utilization. Which device is BEST suited for this purpose?
A load balancer is a device designed to distribute incoming network traffic across multiple servers to ensure no single server bears too much demand. By spreading the load, a load balancer reduces individual server load, prevents any one server from becoming a single point of failure, and improves overall network efficiency and performance. The other options are incorrect. A hub is a simple Layer 1 device that broadcasts traffic to all ports. A patch panel is a passive component for organizing cables. A firewall's primary purpose is to filter traffic for security, not distribute load.
