Training plus wants to open a new training centre in New Castle. You have been appointed as Network Administrative Officer for Training plus New Castle branch. Training institute will use 2 levels of the building. There will be no remote users. The computer network is connected to the high speed Internet. All of their computers are desktop machines and are connected with wired Ethernet connections. All of the network wiring is CAT-6 twisted pair wiring that goes from the office location to a wiring cabinet. There is one wiring cabinet on each floor. Each cabinet is connected to the basement wiring cabinet via fibre. The requirement for the wireless network is the following - - Each floor needs to have two wireless access points, one for the east end of the building, and the other for the west. - The wireless access points will overlap in the middle of the building, so you need to pick different wireless network channels for each end. - On the first floor, there should be an additional wireless access point in the conference room. - The guest network should have a different SSID than the institute's wireless network. It should be configured to allow anyone to connect, with a password. You have been advised to use one network address and create necessary subnetworks for training, administrative and wireless network. Training department will have 4 classrooms each with 25 computers. Administrative and IT department will have 20 employees each using their own computer. There will be a wireless network for institute students which can accommodate 60 hosts maximum. The guest network should have maximum 30 users. Now, your role as Network Administrator to propose a network design to suit for this setup. In order to develop your network design, you may need to make reasonable assumptions. Your objective is to prepare and submit report on the following topics: Topic-1 Select an appropriate IP range for the institute and calculate the appropriate IP subnets. Calculate the subnetwork in such a way so that there is minimum waste of the IP addresses. Create a table and show all the IP subnets with network address, subnet mask and users for each subnet. Topic-2 Prepare and draw the network diagram for this office setup. Mention all network devices clearly (like workstations, routers, servers, etc.) in the diagram. Allocate appropriate IP address for all network devices in the network diagram. Topic-3 Discuss desktop and server operating system types are feasible for this setup. Explain with logic why do you choose each operating system. Topic-4 Provide appropriate Network Security Solution and wireless LAN security to protect from cyber threat of this company.
