P5. Provide a logical/physical design of the networked
system with clear explanation and addressing table.
1. The difference between logical and physical design:
➢ Logical layout of a network can be defined as the mode of communication that connects two computers connected to a network. Logical layout consists of the outflow of data between two systems. In actual sense network connectivity is based on logical design of a network. The physical layout design is installed using logical design. ➢ The logical network can also be upgraded and can be used to connect two or more computers together. Logical design of a network consists of virtual design while the physical design of a network describes the hardware functions of the network. Logical designs determine the flow of data or communication between two networks while physical design is a communication between two computers connected with cables. ➢ For example, a physical design of a network can be upgraded to link two or three office buildings. The expansion would require an upgrade using logical design layout of a network. This would make it easy for information to be processed from any system in buildings at the same time. ➢ Physical layout of a network is based on a logical layout. For example, an organization that installs a wide area network would be drawn as a single line diagram; this is a basic design of a physical layout. Thus, the explanation it means that logical design of a network can be developed or expanded using physical design while retaining its original characteristics. (network., 2013)
- This network system will be managed by GW Server, the server will provide DHCP service for all devices in the system. In addition, GW Server also provides Web, DNS, Email and FTP services.

P6. Evaluate the design to meet the requirements
1. Test plan.......................................................................................................................
No Test plan Purpos e 1 Ping two computers on the same LAN Check the signal of the computer on the same network 2 Ping two computers other than LAN Check the signal of the computer when it is different from the LAN network 3 Ping two computers on different LAN layer Check the signal of the computer between floors 4 Ping between pc to server (^) Check if the signal of the computer is connected to the server or not
2. Evaluate my network design
Advantages Disadvantages
- The advantage is that it makes cable usage efficient and easy to manage.
- In the future, if the user wants to expand the system then it makes it easy to add new nodes without rebooting all of the connected devices. - The devices are connected to a central switch, so when the central switch fails, the entire network will be affected and the cost of rebuilding the system will be quite high. - The VLANs on the 1st and 2nd floors can ping to the rooms of the ground floor, since the ground floor is the working floor of the staff and teachers, so it needs better security.
3. Advice and solutions
- That is, the VLANs on the 1st and 2nd floors can ping to the rooms of the ground floor, since the ground floor is the working floor of the staff and teachers, so it needs better security. Therefore, a supervisor may be needed to prevent this from happening.
- there should be 2 servers (1 main server and 1 backup server) to avoid the main server failure, there is still 1 backup server to keep running. Server device should be supplied with 2 power sources (1 main power source and 1 backup power source) in case the Server is disconnected from the main power source, there will still be backup power to maintain operation. The amount of heat it radiates is quite hot because the server operates regularly, so there is an air conditioning system in the room containing the server and it is necessary to tightly control the temperature and humidity in the room.
- And for the CoreSwitch device it is necessary to have a regular supervisor, because it is an important device that connects the LANs together. If it malfunctions, the network will not be able to work.
- Next comes the DHCP configuration section. The first is to switch the DHCP service to On, then I have named and configured IP addresses for them, from Vlan10 to VLan respectively.
- Next is to set the hostname is CoreSwitch and name the VLANs. Next is to assign IP addresses for each VLAN along with an IP helper command
