Step 1
We will assume that we have a base network address (e.g., 192.168.0.0/24) to work with, and we will subnet it according to the requirements of each company. Show more…

Network Scenario 2: Suppose you are a network administrator of the ABC company. The company has two local departments: HR and Finance. As a network administrator, you are asked to redesign the network so that all systems can access the Internet using a single ISP connection. The following details the individual requirements of each department. 1. HR department: This network will have 10 PCs, one IP phone and one wireless printer. All computers must be connected to the Internet. More devices can be added to this network in future. 2. Finance department: This network will have 12 PCs, 2 IP phones, 1 wireless printer and 1 scanner. All computers must be connected to the Internet. The systems must be secure and reliable. More devices can be added to this network in future. 3. Assume that all end devices support IP addresses. 4. In the following network diagram, PC-A is connected to the HR department whereas PC-B is connected to the Finance department. Figure: Existing network architecture Your Tasks: 1. Modify the network architecture so that all devices can be connected to the Internet. You must try to keep the changes minimal. [Hints: The Week 8 lab on "Testing Network Connectivity with Ping and Traceroute" can be helpful in designing the network.] (5 marks). 2. Assign IP addresses for all devices and interfaces. For a network, you need to assign IP addresses for only the first host and the last host. For example, if a network has 20 host computers/ end devices, you need to assign IP address for only the first device and the last device. Provide a complete table of addressing including Device name, Interface, IP address, Subnet mask and Default gateway (5 marks).

You have to design a network solution for the Fast-NU three Labs, Staff, and Faculty members. All three Labs, Staff, and Faculty members should have networks. There are a total of 15 computers divided in this way: 3 for Staff, 3 for Faculty, 3 for Lab-1, 3 for Lab-2, and 3 for Lab-3. Assume that FAST-NU is given a Network Class B address with the first two octets of the IP address fixed as 172.19.X.X. You can change the next two octets in order to make the desired number of subnets and desired number of hosts in each subnet for the above-given topology. Make sure that you optimally design the network considering the number of devices (switches, routers, etc.) used and how you are assigning the IP addresses to different subnets in your design. (You can consult the slides for subnetting provided to you in case you have no idea about subnetting or you have forgotten it). Use wires (straight through and crossover where necessary and applicable) - no wireless LAN is required for this submission. Use a 2911 Router and 2950-24 switches. You can connect a maximum of two networks with a single router (except router-to-router connection).
2) You have been hired as a Network Analyst for ABCorp. ABCorp has a single site located in Sylvania, Ohio, with 62 devices on an Ethernet network. Your job is to link ABCorp's existing network to the Internet. The internal IP network number scheme is 10.100.20.0/24 and it cannot be changed. When ABCorp originally installed the network, IP address 10.100.20.1 was reserved for the ‐‐Internet router‐‐ (The ‐‐Internet router‐‐ has not yet been purchased). ABCorp would like to use their internal Windows Exchange Server as their inbound SMTP mail server. The IP address of the Exchange Server is 10.100.20.205. ABCorp would also like to connect their internal WEB site to the internet via an IIS Server which has an IP address of 10.100.20.210. ABCorp is unsure of how to obtain an Internet connection and which items to purchase. a. Discuss the various methods by which ABCorp might connect to the Internet (both physical and logical connections). Make a judgment about which physical and logical method(s) might be best for ABCORP and explain all Security measures you would recommend to ABCorp. Justify your answer. (6 points) b. Based on the method and security measures selected above, identify the equipment (in complete detail) ABCorp would have to purchase in order to connect to the Internet (assume only CISCO network equipment). (5 points) c. Produce a working configuration file for ABCorp’s router. This configuration file must accomplish the needs of ABCorp. using the method(s) and equipment selected in (a) and (b) above. (8 points) d. SSK Software (from question 1 above) has entered into a long-term Software support contract with ABCorp. In order to completely and/or timely support the needs of ABCorp. SSK Software would like to inter-connect the two networks from its Toledo location via a CISCO router (connect SSK Software’s network with ABCorp’s network) Using the network layout, you selected for SSK Software in question 1(b) Using information and methods obtained from this CSET4750 class; i. Propose a physical and logical plan to inter-connect the two networks without changing either company’s network numbering scheme. Include (in detail) any equipment either company would need to purchase to accomplish the plan. (4 points) ii. ABCorp would like to limit SSK Software’s remote access onto its network. What entries would need to be configured in order to limit SSK Software’s remote access onto ABCorp’s network to just two PC’s at the same time, using only protocols TCP and/or RDP for remote support?
