Out of the following devices, which one is an internet appliance specifically designed to manage incoming internet traffic and distribute it across multiple servers to prevent any single server from being overwhelmed?
Unified threat management (UTM) appliance

Proxy server
A load balancer is an internet appliance that distributes workload across multiple servers or network links to optimize resource use, maximize throughput, minimize response time, and avoid overload on any one of the servers. Understanding its function is fundamental for students because managing server traffic and maintaining service availability are key aspects of network administration. Internet appliances like Unified Threat Management (UTM) devices focus on security functions, spam gateways specialize in filtering unwanted emails, and proxy servers forward client requests while potentially masking client identities.
