KCA University Ruaraka campus has considered creating a network for the new tuition complex that has just been completed. The building is composed of five floors including the ground floor. You have been tasked to be the designer of this network which will later be connected to the rest of the KCAU network. It is assumed that you will base your design on Ethernet and all the floors will be cabled. It is further assumed that each floor will have approximately 150 computers. On each floor, there will be administrative computers which must be separated from the student computers. 

a) 

(i) What is the minimum number of wiring closets you would create for this particular network? 

(ii) Where would you place your MDF and why? 

(iii) What would be the minimum number of 24-port switches you will use for this network? 

b) Assuming that the average UTP cable run for each computer is 40 metres. How many reels of UTP cable would you require for wiring the whole building? Show your working. (N.B. Assume that the length of one reel of UTP cable is 300m.) 

c) Explain why putting the faculty computers in a separate VLAN could protect faculty network traffic from student connections. 

d) Describe the steps you would follow when designing or modifying the KCAU WAN. 

e) Using a packet tracer simulator, design the above network.

 f) In an Ethernet LAN, devices use one of two types of UTP interfaces - MDI or MDIX. Discuss how these two interface types affect whether you use a straight-through or crossover cable. 

 g) Suppose the network you were to design was not for KCAU but for a home. Home networking has some fundamentally different properties than other network types. Describe briefly six of these properties.
