How can I diagram a network solution for a car dealer to show the following:
merica One Car (AOC) dealership is moving into a newly built facility in a suburb town of Washington, D.C.. You are retained as a consultant by AOC dealership to design a network solution for their new location. The new facility is assumed to be wired with UTP and fiber, with outlets in specific locations. The basic network is to be a LAN that serves desktop computers in the general manager's office, in the salesmen's area, and the showroom area; mobile devices (laptops, smartphones, tablets, etc.); and various accessories (printers, etc.). A major component of the network is a file server (for storing the sale contracts, and other files). Of primary importance is the Internet access solution (e.g., leased lines, Cable, DSL, broadband wireless, fiber to the home, satellite). Other components (such as web server, and database server) may be added for completeness (to earn extra credit).
Design a network solution, considering the following:

• Type and topology of LAN
• LAN cabling
• Storage file server: data back-up/archiving, file consistency, file access logs, and data recovery
• Internet access method (assume maximum availability of solutions)
• Security (all pertinent issues)

• Any other specific issues, such as web and database servers (for extra credit)
