How does a server farm and load-balancing software figure into the multiple DMZ/firewall configuration?

What will be an ideal response?

One DMZ does not provide enough security for many large corporations that are connected
to the Internet or do business online. To handle demand from the Internet and keep the response time of public servers as fast as possible, you should set up multiple DMZs. Each DMZ is a server farm, a group of servers connected in a subnet that work together to receive requests with the help of load-balancing software. This software prioritizes and schedules requests and then distributes them to servers based on each server's current load and processing power.
