Imagine you are a network administrator for Arr Company. The company has six offices in the city of Melbourne and the surrounding suburbs. You need to prepare a networking solution that enables employees in all six offices to communicate both internally in that office and, to a lesser extent, between the other offices. The farthest distance between any two offices is 70 kilometres. Most user resource requirements are met by servers located in the same office as the users who need to access them. The main communication requirements between offices relate to e-mail and periodic file transfers. You have been promised a budget sufficient to meet the requirements, but you have also been told to keep costs to a minimum. The company's head office, on the other hand, occupies the top three floors of a building within the Melbourne CBD. Other companies have offices on the floors below. The head office consists of three departments: general support, marketing, and sales. General support occupies the first of the three floors, while marketing and sales are on the second floor and third respectively. General support has 32 workstations, marketing has 20 workstations, and sales has 38 workstations. Some applications require that data be transferred between departments, but generally, each department has its own applications. Everyone needs access to the Internet, the company internal Internet (intranet), and e-mail. You want to design the network that is as easy to manage as possible. You want to minimise the potential impact of problems on any one floor to the other two floors. You are implementing this network as a wired network. 1. Design a wide area network solution for this company showing all the six office locations and any interconnecting devices such as routers, if any are used. What are some of the potential concerns related to the connections between the offices?
