ASSIGNMENT 2 ANSWERS
P5 Provide a logical/physical design of the networked system with clear explanation
and addressing table.
1. Network design:
1.1 Logical design:
A Logical Network Design is focused on how to layout your plant and enterprise and where you would
locate key distribution points for the network as well as what types of devices and switches you should
use to interconnect the plant. It can also include how to do IP addresses, VLANs, and switch
configurations.
- Below are key features of the Logical Design:
Logical Plant Floor layout
IP Address Scheme and Subnetting
VLAN Selection
Access and Distribution Layer Switch types, models, and ports.
Typical configurations based upon standards
P a g e | 2
1.2 Physical design:
A Physical Network Design determines what the physical infrastructure needs to look like and how to
interconnect all the devices.
Evaluation of Environmental Conditions relating to Physical Media type required.
Space Planning, Pathways, Round
Placement and Configuration of Zone Enclosures
Physical Media required based upon logical design considerations i.e. fiber, copper, conduit types,
etc.
P a g e | 4
First floor and second floor:
Total 2 floors will include 50 computers, and the number of PCs will be divided according to
the decision of the network designer
The method each floor's PC will be linked to a single switch. These two switches will be
connected via a router located on the first or second floor, which will be connected to a
router on the ground level to guarantee that all of the system's components are linked
together.
3. Logical design of the network system
3.1 Logical design diagram:
3.2 Explanation:
Building:
Ground floor :
Teacher’s room: In this room, I will design a system of 15 PCs and a printer and also connect to
each other by a separate switch.
Manger’s room: This room will have 5 PCs and 1 printer, these devices will also connect.
P a g e | 5
Admin’s room: This room will include 3 PCs to meet 3 IT staff, in addition, there will also be a
Web server and DNS server to serve the work and help IT staff to easily maintain and check. The
PCs and servers will be connected by a separate switch.
Marketing’s room: In this room, I will design a system of 12 PCs and a printer and also connect
each other by a separate switch.
First floor:
Lab1: This room consists of 25 PCs connected by 1 switch.
Second floor:
Similar to Lab1: Lab2 have 25 PCs connected by 1 switch.
4. Physical design of network system
4.1 Physical design diagram

P6. Evaluate the design to meet the requirements
1. Design review
In ground floor can ping to rooms of other floors and ping each other. Use 2 servers such as DNS,
Web. From computers in different rooms can ping these servers.
The design as shown includes 6 rooms on 3 different floors. The first room is on the ground floor
including (the marketing room, teacher room, manager room, admin room), the first floor is lab1,
the second floor is lab2.
The student room has 50 computers, of which the first floor has 25 computers, the second floor
has 25 computers. In which, the marketing room has 12 computers and 1 printer. The admin room
has 3 computers and 2 servers. The teacher's room has 15 computers and 1 printer. Room
manager has 5 PCs and 1 Printer. At the same time to meet the needs of the problem. There are
35 machines on the ground floor.

PC( Lab1 1 -> 25) 192. 112. 1. 2 ->
Floor 1 – Lab 1
PC ( Lab2 1 -> 25) 192. 111. 1. 2 ->

2. Evaluate My Network Design
2.1 Advantages
To reduce network congestion, rooms are connected using separate switches and routers.
The data is easily upgraded, introduced, organized, managed, and expanded.
The data transmission process is more fluid in this network architecture because of the high-
speed data transfer rates. There is less harm in the event of a single computer failure because it
does not affect the entire network. There are no network disturbances when attaching or
disconnecting devices.
My network has never had wifi since it would be costly to establish and bandwidth would be
lowered if a large number of people was used.
2.2 Disadvantages
Because the system lacks a wireless router, it is impossible to connect smart phones, laptops, or
other wireless devices.
When there is no wifi when everyone is correct, the PC will not have the network to use to save
money and people are signing mobile data contracts, internet connection speed may be
hampered by difficulties from the supplier.
My network is unable to establish a wireless connection. However, I will address this as soon as
possible.
3. Suggestions for future development
Need to provide a Wifi Router device to be able to connect to wireless devices enabling the use and
collaboration of wirelessly linked devices by workers, instructors, and administrators
The network system has been designed to be both cost-effective and simple to use in practice.
However, if the number of pupils in the school grows in the future, the existing system will be
insufficient to fulfill administration and usage demands.
To guarantee that higher-use requirements are met. In order to upgrade the system in the future, the
