1) Draw a diagram for the above scenario using a drawing program such as Microsoft Visio (2 marks)
Please view Microsoft Visio Document.
2) Provide LAN solution for each office connecting computers and printers together. What types of topology/topologies are you using and why? Explain all connectivity devices used by your selected topology/topologies. (1.5 marks)
UpHillCars should use a star-wired bus topology, which is the best solution while also being cost-effective. The topology that will be used is the star-wired bus topology. [Why?] UpHillarCars should also have a wireless LAN topology. In order to reduce costs and because most users are desktop users, remote access points will be set up in the offices of managers. It would also have

Place these servers along with the other related servers (e.g., VPN server) in a DMZ area. Note: The DMZ is connected to the Internet through a firewall. DMZ (demilitarized zone) is a physical or a logical sub-network that contains and will expose UpHillCars Inc.′s external facing services to the internet. (Anon, 2014) This will add additional security to the organizations LAN. An external attacker only has direct access to equipment in the DMZ rather than any other part of the network. The services that will be provided by the DMZ will be the e-mail, and web servers to the clients. Web servers that communicate with an internal database require access to a database server which may not be accessible publicly and can also contain sensitive information. The web servers can communicate with database servers through an application firewall or database servers directly. E-mail messages and user database are confidential so they are usually stored on servers that cannot be accessed from the internet, but can be accessed from email servers that are exposed to the internet. (Wikipedia, 2014) 7) There are 4 main LAN servers: a Database server, a File Server, an Application server and a Finance server that provides services to all employees as well as managers in three locations. These servers such be installed in the Main office. You need to secure these servers as well. (1.5 marks) Please view Microsoft Visio
