A small business wants to make its website public. Two physical servers that host the website have load balancing configured. Each server has its own Internet Protocol (IP) address. Having only one public IP address from the Internet Service Provider (ISP), what may a network administrator set up so the company's website can interface with public users?

Setting up Port Address Translation (PAT) is the correct choice for allowing a company's website to interface with public users while using a single public IP address. PAT allows multiple devices on a local network to be mapped to a single public IP address, enabling them to communicate over the internet. This is essential in scenarios where there are more devices than available public IP addresses.

By configuring PAT, the network administrator can manage the traffic to each of the physical servers hosting the website using their private IP addresses. When public users request access to the website, those requests can be directed to the single public IP address, and PAT will translate the requests to the appropriate internal server based on the necessary port numbers. This effectively balances the load between the servers while ensuring that external users can reach them seamlessly.

In contrast, the other options do not fulfill the requirement as effectively or are aimed at different purposes. For example, implementing a Virtual Private Network (VPN) is focused on creating secure connections for remote users rather than facilitating public access to a website. Dynamic DNS provides a way to connect to a dynamically changing IP address but does not deal with multiple servers or load balancing. Lastly, setting up a Proxy Server typically involves routing requests through an intermediary server rather than directly allowing access to multiple
