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

Implementing load balancing distributes incoming traffic across multiple web servers, improving availability and scalability, but it doesn't inherently reduce latency for individual content requests from frequently accessed sites if the content still has to be fetched from an origin server each time.

Installing a caching server (e.g., a reverse proxy cache or a Content Delivery Network - CDN) is highly effective for frequently accessed websites because it stores copies of static and dynamic content. When a user requests content, the caching server can deliver it directly, reducing the load on the origin web server and significantly decreasing latency and bandwidth usage for repeat requests.

Placing devices on the same subnet reduces local network latency but has minimal impact on the delivery efficiency of websites accessed over the internet or across larger networks.

Implementing compression on the web server reduces the size of data transferred, which helps with bandwidth, but a caching server directly serves the content, often eliminating the need to re-compress or re-fetch from the origin server, providing a more significant optimization for frequently accessed content.
