Which of the following statements about a perimeter network are true?

A perimeter network, also known as a demilitarized zone or DMZ, is a small network that lies in between the Internet and a private network. It has a connection to the Internet through an external firewall and a connection to the internal network through an interior firewall. It allows outside users access to the specific servers located in the perimeter network while preventing access to the internal corporate network. Servers, routers, and switches that maintain security by preventing the internal network from being exposed on the Internet are placed in a perimeter network. A perimeter network is commonly used for deploying e-mail and Web servers for a company.
