An organization has a web-server farm. Which of the following solutions should be implemented to obtain efficient distribution of requests to the servers?

A clustered web server infrastructure primarily provides high availability and failover rather than distributing individual requests efficiently across multiple active servers.

A load-balancing appliance sits in front of the web server farm and uses algorithms such as round-robin, least connections, or IP hash to distribute client requests evenly across all available servers. This directly solves the requirement for efficient distribution of requests, improves response times, and provides fault tolerance if a server becomes unavailable.

Containerizing an application improves deployment portability and resource isolation but does not on its own distribute incoming network requests across server instances.

Distributing servers across regions and zones addresses geographic redundancy and latency for global users but does not inherently balance the load of requests hitting the same endpoint efficiently.
