The company's main server is using 98% of its available resources and Joe needs to evenly distribute the work to another server using which of the following?

A VPN concentrator aggregates multiple VPN tunnels from remote users into the corporate network - it does not distribute processing workloads between servers.

A content filter inspects and restricts web or application content based on policy - it plays no role in distributing server workloads.

A proxy server acts as an intermediary between clients and servers and can cache content, but it does not evenly distribute a server's existing workload to additional servers.

A load balancer sits in front of a server pool and uses algorithms such as round-robin or least-connections to evenly distribute requests across available servers, directly solving the problem of one server consuming 98% of its resources by offloading traffic to additional servers.
