You are the network manager in a medium sized company, your company decided to open a new branch in Manchester, the Manchester branch located in a modern building in a multi-storey offices. The company director briefs you with the requirement of the requirements as follows:
- There will be 60 users and 6 network printers.
- There need to be a fileserver to be shared between all users.
- The users will share the same web, DNS and mail servers locally.
- As a network manager, you need to allocate the minimal amount of support, and so the need of remote desktop support is essential.
- The company planning to expand in the near future, expecting to add extra users, and servers.
The company would like to facilitate the use of BYOD (Bring your Own Device) initiative to allow users to bring and use their mobile devices in work.
The IT director emphasised on the security, scalability and availability, adding to the fact that the data stored on the servers are as critical in availability as on security, the director provided you with the company network IP address
LO1 Understand network operating systems principles
1.1 Identify and evaluate different types of operating systems available in the market, your evaluation and discussion should include the following: [P1.1, P1.3, D1]
- the requirement of the above scenario network services
- suitable network for the above scenario
- Critical comparison and evaluation of different network operating systems available in the market in terms of (software availability, security, Technical support, etc.) that can fulfil the requirements of the given scenario
- Based on you comparison and justification, recommend network operating system
1.2 Business continuity and disaster recovery are crucial for any organisation; discuss the following in relation to disaster recovery: [P1.2, M1]
- What do you understand by the term disaster recovery & Business continuity
- Explain the benefits of implementing an effective disaster recover strategy
- Explain different types of backup options and devices
- Explain different RAID options in relation to availability
To achieve M1, you should have made effective judgement including 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.
LO2. Be able to plan the implementation of network operating systems
2.1 Prepare a detailed plan for the implementation of NOS with the following information: [P2.1, D2]
- Installation: Server hardware specification, (your hardware configuration must be compatible to the Operating System you have chosen)
- Addressing: IP address allocations for all the servers, workstations and printers, including the CLASS and range of IP Address.
- 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
- Simulation: produce a network simulation for the above network. 2.2 Evaluate and justify you plan and users feedback including [P2.2, M2]
- Hardware selection in relation to the scenario requirements such as. RAID, Memory, Processors etc.
- Network components.
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.
LO3. Be able to implement network operating systems
3.1 Implement your selected NOS by including: [P3.1, M3]
- Installation: show step by step installation process ( the screenshots of the installation process from LAB) and document the process steps
- Services: required services & any specialised configuration
- 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]
- Security: Setting of administrative rights, setting of password policy etc.
- Network simulation: use any network simulation system to simulate the network.
- 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.
LO4. Be able to manage network operating systems
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.
