Assignment Task

This is an individual assignment based on the case study scenario presented below. This assignment will assess your understanding of the principles of network design and the ability to analyse, design and create a network infrastructure fully configured and tested which reflects understanding of network design and troubleshooting.

Scenario

As a network engineer you have been asked to design and implement a small network for one of your company clients (alm.co.uk), the network consists of 4 (four) departments.

The network consists of four Servers, web, email, dns, and common file server, all servers shared between all users. The distribution of workstation shown in table 1, describe the requirement of each department. The college admins decided to use wireless network for use by any student/staff using their own wireless device such as smartphone to access the internet.

Dept.	Devices	Access Rules
1	48 Computers one printer	Users cannot access any other department
2	18 Computers one printer	Users cannot access any other department
3	11 Computers one printer	Users cannot access any other department
4	68 Computers one printer	Users cannot access any other department

Table 1: workstation and server distribution and requirements

The IT director emphasised on scalability, availability and hence you are required to provide a complete network infrastructure design and implementation, the company will be using private IP address 192.168.168.0/24 within LAN, the company network availability, Scalability and security are very important. The wireless network IP address is 10.11.12.0/24

Task

Analyse the requirements given in above scenario evaluating suitable network model and components to design a network infrastructure featuring scalability, availability and security.

Based on your analysis and evaluation you are required to apply the required configuration for the selected components, and finally, you are to discuss, evaluate and apply Network monitoring tools/components, and produce network test and documentation suitable for network maintenance.

All relevant network configuration, network diagram and device configuration tables, network simulation file must be included.

Deliverables

• Create a complete network diagram for the given scenario.
• Create an appropriate subnet based on given network address.
• Create VLAN for each department.
• Justification of the use of network design model and components including any technologies/protocols used
• Provide complete security precaution and configuration where applicable including: Access control list to isolate each department internally.
• Complete testing documentation of all relevant devices such as web, email, DNS servers.
