[View full size image]

With a single switch, you have a single broadcast domain and a single LAN. However, your new boss told you when you walked in the door, "We've got to get Fred and Barney on a different LAN than Betty and Wilma. They work with super-secret projects, and we can't meet our security requirements if Betty and Wilma are on the same LAN. Now get cracking!"

To put Betty and Wilma in a different LAN than the boys, you have to use two switches. Figure 7-3 shows the alternative design, now with two physical LANs.
