Outfit is a well renowned fashion retail company. The companys head office is located in the Melbourne CBD. The head office consists of three departments: general support, marketing, and sales. General support is located on the first floor, while the marketing and the sales departments are located on second and third floors of the building respectively. General support has 12 workstations, marketing has 15 workstations, and sales has 20 workstations. Some applications require that data be shared between departments, but generally, each department has its own applications. Every workstation needs access to the Internet, the company internal Internet (intranet), and e-mail. Each floor has a printer connected on the network. The head office also requires wireless internet connectivity for all the floors. The company is also planning to establish five offices in Brisbane, Adelaide, Sydney, Canberra, and Darwin. According to the specifications provided, the most user resource requirements will be met by servers located in the same office as the users who need to access them. The main communication requirements between offices relate to print jobs, e-mails and periodic file transfers. Suppose you are hired as the network engineer of the company to design the network for the head office. The area manager of the company has asked you to prepare a networking solution that enables employees in all five offices to communicate both internally in that office and, to a lesser extent, between the other offices and head office. The network design incorporates both wired and wireless networks.
