150 users during peak hours, computers have good conditions for fast, flexible, and future growth.
- More users in the future. Network personnel can sit on 3 floors to control the network. Mail server is available to serve students and students in the school. Grant domain names to employees, teachers, and students. There is a webserver to serve and update information and schedule for students. employees, teachers. Network system designed for all students, teachers, and school staff to connect and use the internet. and all computers in the school can communicate with each other.
- People: 200 students, 15 teachers, 12 marketing and administration staff, 5 higher managers including the head of academics and the programmer manager, 3 computer network administrators.
- Resources: 50 student lab computers, 35 staff computers, and 3 Printers.
- First floor: contains 35 staff computers, 1 Wireless and 1 printers
- Second floor: contains 25 student lab computers, 1 Wireless and 1 printer
- Third floor: contains another 25 student lap computers, 1 Wireless and 1 printer
- Logical Design The network setup for a three-story building incorporates various symbolic network devices such as routers, switches, PCs, printers, wireless access points, and servers. In this configuration, a router is linked to a layer 3 switch, facilitating connections to switches across the floors to furnish internet access to devices. Additionally, wireless access points are deployed to serve teachers and staff, extending network accessibility. Given the substantial number of users requiring simultaneous access, a high bandwidth infrastructure has been implemented to accommodate the demand. The layer 3 switch assumes a pivotal role by provisioning DHCP services for PCs on each floor and serving as the central command hub for network control and management. This comprehensive network design aims to meet the diverse connectivity needs of the building's occupants efficiently.

P6: Design a maintenance schedule to support the networked system.
What is a network maintance? At its core, network maintenance constitutes all the tasks and systems in place to monitor, update and run your organization’s computer network before problems strike. That “network” itself involves your entire portfolio of physical IT assets, like the hardware and servers, and non-physical IT assets, like the software and cloud access — also known as your IT ecosystem. Similar to other business functions, a healthy IT ecosystem relies on proactive, daily activities and strategic foresight rather than reactive adjustments or ad-hoc, spur-of-the-moment patches. The basic tenets of maintaining your network — and the basis of a successful regular network maintenance plan — typically include the following:
- Network cybersecurity: Implementing robust and up-to-date network defense layers, such as traffic-managing firewalls, virtual private networks, user access controls, double authentication measures, log inspections for usage documentation, real-time breach notifications and auto-generated security reports.
- Network performance : Analyzing top network performance concerns influencing the speed and reliability of your devices, including bandwidth usage, traffic patterns, bottlenecks, frequently down or crashed servers, connection lags, delays and more.
- Network scalability : Ensuring proper software and hardware systems fitting your current operations, number of network users, endpoint locations and businesses functions.
- Regular hardware and software updates : Scheduling updates prorated across network components and interfaces, which in turn bolsters both a network’s overall performance and security defenses.
- IT infrastructure compliance: Maintaining internal compliance with company practices as well as external government regulations and industry policies. (Anon., 2023) System maintenance plan table
- Check hardware every 1 months
- Scanning malware every Saturday
- Checking users access
- Testing software, checking software updates every 2 days
- Backup configuration on network devices on the first day of the month
- Checking firmware on every Thursday
P7. Implement a networked system based on a prepared design
Step 1:
- Remane Multiplayer Switch Core:
Step 2
- Configure VLANs in Multiplayer Switch:
- IP routing in Multiplayer Switch
- DHCP service for Student PCs, Staff PCs , Printer, IT, Server :
Step 3: On Switch(0,1,2,3) configure vlan trunking protocol.
- Configuration for Switch 0
- Configuration for Switch 1:
- Configuration for Switch 2:
Step 4 : Configuration for Border and ISP Router:
- Configuare Border router, set ip:
- Configuare Nat: Completely Configuaration:
P8: Document and analyze test results against expected results
- Document Step 1: Configure multiplayer switch to become VTP server and set name for Vlan, to provide Vlan for the Client Mode Step 2: Set trunk mode for ports of multiplayer switch that’s connect to each others switch Step 3: Configure IP address for each Vlan in multiplayer switch Step 4: Configure DHCP Relay
Step 9: Configure NAT on Border Router Step 10: Configure ISP Router
- Testing Plan Active Result Reason PCs in school received DHCP Successful DHCP has been routed PCs in the school can access internet Successful Router has been routed PCs in school can ping each other Successful Switchs has been trunked PCs of marketing, Staff, Teacher can ping to other devices in school Successful Vlans has been routed Students PC can’t ping Teacher PCs and Facebook Successful Vlans has been routed Check NAT: Public PC can access IP 1.1.1.
