Introduction
Mr. Nguyen, satisfied with your report 1 and he wants you to meet his requirement 2, I need to design the network according to Mr. Nguyen's requirements then I need to prepare the plan and test that plan by evaluating the design against Mr. Nguyen's requirements, next I need to test my network with ping, line tracking, email,..... results and reports compared to expectations
Through the report, I need to learn from experience and from there upgrade and edit the network system to best suit the user's requirements.
I. Provide a logical/physical design of the networked system with clear explanation
and addressing table
1.1. Explain the difference between logical and physical design.
Physical design layout outlines the pieces of the logical design network which are in a given network architecture. Besides, it refers to the arrangement of computers and other physical components. Its components include Fiber, ISDN and Ethernet. The logical design network assumes a particular piece of a conceptual design in a network and assigns it a logical role in a within that framework. Its components consist of IP structures of the network such as Class A, B, or C address scheme.
a. What is Logical design
A logical network design tell us information in the network flows. In a logical design, you will generally visualize the following elements in your logical network topology:
Subnets Network objects Specific routing protocols Routing domains Voice gateway Traffic flow Network segment
As the information contained within logical network diagram corresponds to the Layer 3 of the OSI model; Layer 2 devices are not depicted in an L3 or logical network diagram. While physical network diagrams are important, logical diagrams make network management casier in the following ways:
Troubleshooting Firewalls Eliminate redundancies Capacity planning
Designing a network can be a challenging task. Your first step is to understand your networking requirements. The rest of this chapter explains how to determine these requirements. After you have identified these requirements, refer to Chapter 2 for information on selecting network capability and reliability options that meet these requirements.
Networking devices must reflect the goals, characteristics, and policies of the organizations in which they operate. Two primary goals drive networking design and implementation:
Application availability —Networks carry application information between computers. If the applications are not available to network users, the network is not doing its job. Cost of ownership —Information system (IS) budgets today often run in the millions of dollars. As large organizations increasingly rely on electronic data for managing business activities, the associated costs of computing resources will continue to rise.
In general, users primarily want application availability in their networks. The chief components of application availability are response time, throughput and reliability.
b. Requirements of assignment scenario People: 200 students, 15 teachers, 12 marketing and administration staff, 5 higher managers including the academic heads and the programme 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.
1.3. Logical design of the network based on the specific requirements of the
user
1.4. The address table of the network devices used in design above.
255.255.255.0 N/A
II. Evaluate the design to meet the requirements
2.1. Test Plan
Test Case Action Description
1 Check the port status Click interface then make sure all port is on 2 Ping from PC TVS1,2,3 to MKT&M1,2,3 Ping from the PC on the 1st floor through the PC on the 2nd floor 3 Send email from PC on the other room to another room
Open Network Administrator, click desktop then click email and use compose to send email 4 Check DNS email Open Network Administrator, click desktop then click IP 192.168.30.
5 Check Server PT www.Hoang.com^ Open Network Administrator, click desktop then check IP 192.168.25.
2.2. Evaluate network design
a. Showing the pros and cons of design based on user requirements
Advantages :
Simple but effective design, divided into 3 distinct floors with 3rd floor for administrators and 1st and 2nd floors for student and laboratory rooms. Computers can ping each other Students have computer labs, computers can access mail, web. Easy to modify and change if there is a mistake.
Disadvanteges:
Some servers are missing. If DHCP server is wrong then all fail.
Fastethernet0 in Interface => Configure IP addres
Ping DNS server by click on the desktop mode on PC TVS2. Then continue to type the IP address of DNS. Ping 192.168.5.3. 0% loss prove that I have already successfully configured the DNS
Check DNS service by use certain PC or Laptop

Configure DHCP1 Server
First we need to enter ID, Default Gateway and DNS server
