Which of the following network optimization techniques would be MOST appropriate far more efficient delivery of frequently accessed websites?

Load balancing distributes traffic across multiple backend servers to prevent overload, but it does not reduce the number of origin fetches or improve delivery speed for repeated requests to the same content.

A caching server intercepts requests for frequently accessed content and serves responses from a local store rather than fetching data from the origin server on every request. This eliminates redundant round trips across the network, reduces latency, and lowers bandwidth consumption for end users. It is the most targeted solution for optimizing delivery of content that is accessed repeatedly.

Placing devices on the same subnet reduces network hops and can marginally lower latency, but it does not eliminate redundant fetches or store content locally to speed up repeat access.

Compression on the web server reduces the payload size of each response, which helps bandwidth efficiency, but it still requires a full round trip to the origin server for every request rather than serving from a local cache.
