SECTION 1 - PROVIDE A LOGICAL/PHYSICAL DESIGN OF THE NETWORKED SYSTEM WITH CLEAR
EXPLANATION AND ADDRESSING TABLE (P5)
➢ Logical Design: − Definition: The logical network design is made up of separate networks that are physically realized using virtual local area networks (VLANs) specified by network switches. ➢ Physical Design: − Definition: A Physical Network Design specifies the physical infrastructure and how all devices will be interconnected.
1. Explain the difference between logical and physical design: ✓ The logical design is more abstract and conceptual than the physical design. In logical design, you examine the logical relationships between objects. The physical design considers the most efficient method of storing and retrieving items. ✓ 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. ✓ The primary distinction between logical and physical network design is the iterative generation of a solution from problem identification. When a company has to exchange information in real time with remote offices, they think about business first and technology second. This is when an issue is identified, and as the problem is documented, it may be iteratively transformed from a logical answer into numerous different physical designs. A network's logical design can be re-implemented with new technology while maintaining the same logical design. A physical design is one realization of a logical design that may span decades of technology. 2. Discuss and explain the User requirement for the design: 2.1 User requirement: − As a user, I want to design networking system is an optimal and suitable networking system.

❖ Solutions: o Update the firewall o To achieve top performance, the system must use the best hardware available and account for unanticipated situations such as too many people attempting to use the system at the same time. SECTION 3: Implement a networked system based on a prepared design (P7)
1. Show proof of the network implementation: ❖ Configure D1: Step 1: Configures VLAN on D1: o First, we'll open the CLI and specify the S1's hostname. Next, configure the VLAN and name each user.
o Result
o We will proceed with the remaining SWSERVER to SWStudentB:
o Result
Step 2: Configure IP addresses for switches Step 3: Turn on DHCP for the server.
Step 4: Configure dynamic IP addresses for end devices ❖ Router to R-ISP connection: Step 1: Configure the router's IP address and no shutdown command. Step 2: Configure IP address and no shutdown command on ISP
o Distribution layer : The distribution layer is a routing layer that resides between the access and core layers and is responsible for routing and packet modification. o Access layer: This layer is also known as the desktop layer since it is responsible for connecting client nodes to the network.
SECTION 4: Document and analyse test results against expected results (P8)
1. Document of the implementation process: Devices Quantity Description Switch 9 A switch enables networked devices to connect to each other. Configure VLAN and trunking between the core switch and router on D1. D 1 A switch enables networked devices to connect to one another. Configure VLAN and trunking between the core switch and router on D1. Server 4 The server will store, deliver, and process data and then transfer to workstations 24/7 for users. Used for configuration in the server administration room R 1 Routers link devices in a network by transferring data packets between them. Configure the Gigabyte Port and SubInterface. Computers 85 User devices. Configure IP addresses to correspond to VLANs. Printers 3 Configure static addresses in conjunction with VLANs
