PART 1: Mini Case (60 points) Call Pro (hereafter CP) is a newly founded call center. It has 3 departments (D1, D2 and D3) located on 3 floors of a building. Each department will have its own LAN, each connecting 24 clients, 6 servers and 1 network printer. All clients (NICs included), servers (NICs included), and network printers have already been bought and do not need to be considered in this exercise. 1) Clearly explain (i) what "structured design" means, (ii) its main benefit(s) and (iii) how it applies to CP's network (6 lines MAX) 2) Clearly explain which application architecture(s) you would recommend for CP's network applications and why (4 lines MAX) 3) Using a structured design approach, list (i) each type of hardware component needed, (ii) their specific purpose and (iii) the required quantities 4) Consider the numbers in Fig. 7-6 of p.193 of your text. Clearly explain: a) What they refer to ( 2 lines MAX) b) How they affect or don't affect EACH of the 3 technical goals for CP's network ( 2 lines MAX per technical goal) 5) Consider the definition of "managed network" in Ch.12 of your text. a) Briefly explain what a managed network is (2 lines MAX) b) Briefly discuss the components it requires (10 lines MAX) c) Briefly explain how using a managed network affects each of the 3 key technical goals covered in class (6 lines MAX) 6) Log onto www.cdw.com and determine the cost for CP's network. Assume for simplicity that: - all prices are in Canadian dollars - Cat 5e, Cat 6 and fiber optics have a fixed cost per circuit to buy and install, regardless of distance of $100,$150 and $200 respectively. 7) Using the software of your choice, draw a professional diagram of CP's network. PART 2: Subnetting problem (20 points) Your company has been assigned a Class C address with a network number of 196.10.6.0. Your needs analysis shows that your network requires 15 subnets. Answer the questions below and show your work. 1) How many bits must be borrowed for the subnet ID? 2) What is, in decimal format, the subnet mask required? 3) How many hosts can there be on each subnet? 4) How many subnets can this subnetting scheme accommodate? 5) Briefly discuss the expansion plan provided by this subnetting solution (3 lines MAX) PART 3: Selecting the perfect components for a network (20 points) Read notes 1 to 5 below, log onto the website of an IT vendor of your choice and complete the table on page 4 using 25 words MAX per cell. Note 1: "Desirable feature" is an aspect of a specification linked to one of the 3 key technical goals covered in class. Note 2: "Rationale" means that you must explain the link between that specific feature and the chosen technical goal. Note 3: Do NOT use availability in stock, data rates supported and cost as these are too obvious and/or not linked to the 3 key technical goals in question. Note 4: Do NOT use the same aspect more than once. For example, do not the same aspect of the specification for the server and for the switch, or for the switch and for the cable. Note 5: List all your references (NOT part of the word counts!)
