The International School of Chefs (ISC) has 500 students and 32 full-time and part-time faculty. There are two computer specialists who maintain the servers, workstations, and network. The school has five Linux servers and two servers running Windows Server 2008 R2. One of the Linux servers is used for the schools Web site. There are eight kitchens used for teaching, 15 classrooms, and two computer labs containing Windows 7 and Mac OS X Lion computers. Only the computer labs use wireless networking. ISC offers a two-year program that includes a full range of cooking courses plus courses in nutrition, health, and restaurant management.

Problem: The computer specialists at the International School of Chefs have received funding to purchase network-monitoring hardware. Up to this point when there has been a problem with a network segment, they have called a local company that support networks. Now they plan to do much of this troubleshooting by using their own equipment. They plan to troubleshoot only those portions of the network that have UTP cable and wireless communications. What network-monitoring devices do you recommend they purchase, and why do you recommend them?
