A network administrator has been tasked with configuring access to the Internet for about 50 computers. The administrator has been told that all Internet access should go through a single computer so incoming and outgoing traffic can be screened and only that computer should have an address revealed to the Internet. What should the administrator set up?

Proxy Server.

Explanation:

An administrator was given the responsibility of customizing Internet connection for around the numbers of computer systems. He stated the admin that those Internet connections need to go through a system connected to the internet because otherwise inbound and outbound traffic can still be examined but only that systems should have a Web address identified.

So, the admin configured Proxy Server because only certain systems have been identified the following address to the internet.
