This Unit will be assessed by assignment and Presentation. You are strongly recommended to read "Preparation guidelines of the Coursework Document" before answering your assignment. ASSIGNMENT 1. Objective This coursework is designed in the form of set questions and design scenario. The tasks are divided into four sections, with section compromising several questions. The coursework should be submitted as one document in a report format. Assignment Scenario: You are working as a network server engineer. You have been assigned a new project to design, implement and support the network of a recruitment company which was established in 2014. The company planning to install 122 client computers, two servers and four network printers, so that they can meet the company requirements. All users should be able to share all the printers, but department within the company will need to share a specific folders assigned to each department. The company data should be treated on high level of security in terms of confidentiality and availability. So, all users should be controlled and managed by an administrator according to users' needs and requirements, and all the machines within the network should be up-to-date with the new patches and service pack and latest security patches to avoid any security related issues. The company as well forecasting an expansion in the foreseeable future and hence you have to put in mind the capability to expand the network when needed (Scalability). The IT manager of the company decided to use a private IP address Range of 10.20.0.0 /24 to be distributed on all the network devices including the servers, workstation and printers. The network manager specifically asked for the following criteria to be fulfilled for the project (Software availability, Scalability, Maintainability and Technical support) Task 1 1.1. Identify and evaluate different types of operating systems available in the market, your evaluation and discussion must include the following: [P1.1, P1.3, D1] o Identify the required network services for the above scenario o Discuss the available network operating system that can fulfil the requirements. o Critically compare and justify different network operating system available in the market in terms of (software availability, security, Technical support, etc.). o Based on your evaluation and justification, recommend a network operating system for the above company 1.2. Business continuity and disaster recovery are crucial for any organisation, discuss the following in relation to disaster recovery: [P1.2, M1] o What do you understand by the term disaster recovery & Business continuity? o Explain the benefits of implementing an effective disaster recover strategy? o Explain different types of backup options and devices? o Explain different RAID options in relation to availability?  To achieve M1, you should have made effective judgement including a relevant theories and techniques have been applied and met the deadline to submit the tasks and achieved the unit assessment criteria.  To achieve D1, you should have made a detailed comparison of many operating system available in the market giving the advantages/disadvantages of such operating systems in view of the requirement given in the scenario based on which you should select the most appropriate operating system justifying your choice by eliminating any disadvantages and rectifying the weakness concentrating on security, maintainability and software availability. Task 2 2.1. Prepare a detailed plan for the implementation of NOS with the following information: [P2.1, D2] o Installation: Server hardware specification, (your hardware configuration must be compatible to the Operating System you have chosen) o Addressing: IP address allocations for all the servers, workstations and printers, including the CLASS and range of IP Address. o Security: what do you understand by the term password policy, patch management etc.. o Disaster recovery: explain what would you prepare in case of disaster 2.2. Evaluate and justify you plan and users feedback including: [P2.2, M2] o Evaluation of hardware selection in relation to the scenario requirements i.e. (RAID, Memory, Processors etc...) o Components: Evaluate network components scalability and Availability  To achieve M2, you should have made effective judgement including a range of relevant theories and techniques have been applied, a range of sources of information has been used.  To achieve D2, you should have made a plan by which you have accounted for the unforeseen and accommodated the plan with necessary devices/routines disaster recovery, including alternative approach and critical evaluation procedures and user feedback, demonstrating autonomy and independence. Task 3 3.1. Install your selected NOS including: [P3.1, M3] o Installation: step by step installation process document (Show the screenshots of the installation process from LAB) o Services: required services & any specialised configuration o Naming: Directory services, application of addressing 3.2. Configure and test password security policy, including adding users and groups to meet the given requirement [P3.2, P3.3, D3] o Security: Setting of administrative rights, setting of password policy etc.. o Network simulated: show how devices can access services and/or other devices using any network simulation. o Documentation: analyse and document your network against scenario requirements giving some recommendation to enhance the performance and availability.  To achieve M3, you should have made an appropriate structure to fulfil the requirement of the given question, including a range of methods in presenting the solution using appropriate technical language accurately.  To achieve D3, you should have applied and effective and creative thinking in unfamiliar contexts including self-evaluation in solving problems, providing alternative methods and/or approach in the solution given. Task 4 4.1. There are many tools available in the market to monitor the network, identify, select and justify one of the tools to produce a performance baseline report. [P4.1] 4.2. Network operating system should always be monitored against threats, Justify and produce Baseline Security Report, including (Patches & Security updates, NOS vulnerability, Weak password, etc.) for the client network. [P4.2, P4.3, M3]  To achieve M3, you should have made an appropriate structure to fulfil the requirement of the given question, including a justification in using appropriate tools and a range of methods in presenting the solution using appropriate technical language and tools. Presentation As part of the overall assessment of this assignment, you will need to prepare an oral presentation of your individual work. You will use power point presentation or similar presentation package of your choice. The presentation will last 10 - 15 minutes. You will be marked on content, presentation style and clarity of delivery. Relevant Information 1.
