In Chapter 1, "Analyzing Business Goals and Constraints," you learned about ElectroMyCycle, a manufacturer of new electric motorcycles. ElectroMyCycle has chosen you to design a new network that will let the company scale to a larger size. The campus network will support about 200 employees and a new data center. Another feature of the campus network will be a state-of-the-art manufacturing facility with networked equipment that communicates with servers in the data center that support real-time control and management. Engineers will access the servers from their PCs in the access layer of the campus network. ElectroMyCycle will sell its new motorcycle both online and through a large retail company. For online sales, ElectroMyCycle plans to have a DMZ that connects a public web server, a DNS server, and an email server. The web server needs to communicate with back-end servers in the data center that hold customer billing data. ElectroMyCycle also plans to open a branch sales office in the city where the retail companys corporate headquarters reside, about 500 miles from ElectroMyCycles headquarters. Design and draw a logical topology that will support ElectroMyCycles needs. In addition to meeting the specified needs, be sure to consider security.
