Discuss and explain the user requirements for general network design. The specification of the project is given below:  People: 200 students, 15 teachers, 12 marketing and administration staff, 5 higher managers including the academic heads and the program managers, and 3 computer network administrators.  Resources: 50 student lab computers, 35 staff computers, and 3 printers.  Building: 3 floors, all computers, and printers are on the ground floor apart from the IT labs – one lab located on the first floor and another located on the second floor. This is a clearly user requirements from the customer: 50 computer lab computers. 35 staff computers mean 32 staff computers and 3 computer networks administrators. 3 Printers. 3 switches. Before making a successful and completely either Logical or physical design, we should separate them into suitable electronic devices for each floor effectively:  Main connection 1 Router: The main connection to receive and send the data to other devices with different IP addresses 1 Switch: Used to receive and send data to a server. 1 DNS server: The necessary devices which connects and configure randomly IP address through DHCP to other devices

 Ground floor 32 staff computers: Staff computers are connected through cables with different IPs to contact with people. 3 computer network administrators: Used to investigate and repair the network problem. 3 printers: Used to print necessary documents for staff. 1 Switch: Used to send and receive the data in the staff area.  Floor 1: 25 students’ lab computers: Standard student computers to work and program. 1 Switch: Used to receive and send data in only floor 1.  Floor 2: 25 students’ lab computers: Standard student computers… 1 Switch: Used to receive and send data in only floor 2. I have separated and contributed a suitable and effective connection.

Provide a logical design of the network based on the specific requirements of the user. Figure 3 : DNS service

provide the address table of the network devices used in your design above. 5.1: Net 0 Net 0: 192.168.199.0/24. Figure 9 : Example of connecting network Server-PT: IP: 192.168.100.

P6 - Evaluate the design to meet the

requirements.

Provide a test plan for the design above. 1.1 Physical device.  Cable types To connect devices together, I will use the cable which is called “Copper straight through” on the third position which used to connect with other device together. Figure 15 : Black cable on the right side. This is an simple example of using copper cable to connect between computer and Switch together. Figure 16 : Simple connection by cable.  Ground floor. To connect the physical device reasonable, I will need: 32 staff computers. 3 admin computers. 3 printers. 1 switch. This is how the ground floor connection is:

 First floor: To conenct the first floor, I will need: 25 lab computers. 1 switch. This is how the conenction on the first floor is.  The second floor. As same as the first floor, I just need only: 25 lab computers. 1 switch. The second floor connection will be like this. 1.2 Configure IP, DHCP, DNS.  Set up DNS server and service The server is the most important to send the data to the other devices to connect it, click the server. To configure the DNS server choose the icon server like this: Figure 17 : DNS server Icon. Click the server->Service-> Find DNS words and click it then cofigure the ip address for DNS server.

Fa 2/0: 192.168.1. Fa 3/0: 192.168.2. Click the router->config->fa0-> fill in Ip address for the connection. Similar with the rest of them. Switch and printer are not necessary to be configured IP address so let move on devices After connecting the main connection to every floor, I will configure IP address to the staff computer, admin, lab pc which includes 3 of floor together: This is an example of staff computer IP configuration as 192.168.0.1 on the ground floor. Figure 20 : IP address for router as an example. Similar with the rest of them, but actually, you don’t need to do them one by one, you can use DHCP configuration for randomly IP address quicker.  DHCP configuration. To make DHCP configuration connection to all devices. I have to configure the server information which includes IP address and DNS server. This is a server configuration. Figure 21 : Example of server configuration before DHCP This will help you to give the 88 computes with randomly IP address.

Evaluate the network design. 2.1 The pro and cons. Advantage Disadvantage  Easily for the first configuration.  Less router connection.  Simple Lan connection and Wan connection.  DHCP helps to connect randomly IP address.  Highly amount of computer connection which is confusing and complicated.  Randomly IP address will led to difficult devices found. 2.2 Solution for network design. Usually more than 50 computers connection can be very complicated and stressful for the people. If I take Ip configuration by myself without DHCP, it will be very long and exhausting. Connecting more than 50 devices can led to some unexpected mistake and failure if you are not careful To connect the device more accurately and less difficult. In my opinion, you will need to prepare your physical devices first, then try to connect them one by one with IP address, DNS and default gateway. However, with the others computer. DHCP is highly recommended for you to save time and give accurate IP connection as long as you configure Server first. I prefer using logical network because of simple connection more than complicated and stressful physical topology.

 Step 2. Now configure the server IP address, click settings to configure Gateway and DNS server: Example: Gateway: 192.168.100.100. DNS server: 192.168.100.1. Figure 24 : DNS server ( Settings)  Step 3. Then, Click Fa0, Fill in information. Figure 25 : DNS server ( Fa0)  Step 4 Click Router-> RIP to connect different IP address together:

Figure 26 : Router (Rip)  Step 5. Finally, choose one of them (Computer or Admin computer)-> Click Desktop-> Click this Command prompt icon. Figure 27 : Command Prompt Check the IP address if it is correctly.
