Your assignment should include: a title page containing your student number, the module name, the submission deadline and a word count; the appendices if relevant; and a reference list in Arden University (AU) Harvard format. You should address all the elements of the assignment task listed below. Please note that tutors will use the assessment criteria set out below in assessing your work.
Maximum word count: 4,000 words
Please note that exceeding the word count will result in a reduction in grade proportionate to the number of words used in excess of the permitted limit.
You must not include your name in your submission because Arden University operates anonymous marking, which means that markers should not be aware of the identity of the student. However, please do not forget to include your STU number.
A new primary school is being built to replace outdated buildings that are beyond economic repair. The school consists of a single building laid out in a square with an open quadrangle courtyard in the middle.
One side consists of the main reception and school office, the head teacher’s office, a large assembly hall that is also used as the dining hall for school lunch and for indoor PE lessons plus toilet facilities for staff and visitors. There is also a staff common room and kitchen in this wing of the building. There is an IT room in one corner of the building which is to house servers, switches, routers and other infrastructure in an air-conditioned room with dedicated power supply etc. Basic IT support is provided by one of the teachers, who has some training in this area, with additional help from the local education department’s IT department.
The remaining three sides of the building house various classrooms, children’s toilets, stores and specialist facilities.
There will be two specialist computer rooms which will have 15 computers each, plus a suitable range of peripherals such as printers. These two rooms will be timetabled for classes to go there to do relevant work using the computers. All other classrooms will have a single computer at the front which is connected to an interactive whiteboard and is used in place of the traditional chalk board for class teaching. The school will also have a set of 15 Android tablets that can be booked out by any teacher for use in any classroom.
The school office, the head teacher’s office and the staff common room will each have computers which are available for staff use for lesson preparation, recording of pupil information and progress and the administration of the school.
As this is a new building, there are suitable service ducts between sections of the building and all the ceilings are suspended, allowing for all wiring to be concealed and secured.
You are to design an appropriate local area network infrastructure for this building. You may make assumptions about what is required but these assumptions must be appropriate to the scenario given and must be stated. You must as a minimum include a switch, a wireless access point, a router, a server, end devices, and an Internet connection in your design.
This assignment is split into tasks detailed below that cover the required aspects of the design. Not all aspects of the network design are asked for in order to keep the assignment to an appropriate size. Only cover the things that are asked for.
Each task addresses aspects of the learning outcomes listed after the task title. The assignment as a whole covers all the learning outcomes, spread across the tasks. You should answer the tasks set, in the order they are set and clearly label each task. Do not treat the Learning Outcomes as if they are the tasks to be answered. LO4 is covered throughout the report.
Task 1 – Benefits of Networking
Write a brief report for the head teacher explaining how a school wide network would benefit the school. This must be clearly focussed on things that are relevant to a primary school and not just be a generic list of the benefits of networking.
(10 Marks) (LO1, LO5)
Task 2 – Network Design
Design an appropriate local area network infrastructure for the school. You must as a minimum include a switch, a wireless access point, a router, a server, end devices, and an Internet connection in your design.
- Provide logical network diagram(s) showing how the school might provide the required services and connections. This may be one or more diagrams as you see fit. Any suitable drawing package can be used and you will not be graded on the drawings themselves; just the network design. The diagram must be clearly labelled with all critical information including but not limited to identifying the devices used and the media used. This part only requires labelled diagram(s). No written text is required other than the labels on the diagram.
- Outline the cabling requirements for your design. You will need a basic plan of the school to create a physical layout design to determine the cabling requirements. You can work with any plan available from the Internet. Identify and justify the type(s) of cable(s) used. Provide approximate costs based on referenced supplier information found by searching the Internet. Since the school is in the UK, the supplier and price must be UK based.
- Explain each infrastructure device, what its function is and why you have selected that device for the job, clearly linking this to the information in the diagram(s) in part (a) or part (b). This explanation must focus on the school and its requirements.
- Identify and justify TWO specific products that could be used for each infrastructure device on basis of their technical specs, exact make and model, supplier and the price. Since the school is in the UK, the supplier(s) and prices must be UK based.
(35 Marks) (LO2, LO3)
Task 3 – IPv4 Addressing
For the network you designed in task 2, devise appropriate IPv4 address allocations and explain how these will be implemented. You need to include both static and dynamic addresses in your scheme. You should cover the following:
- Actual addresses and address ranges used, with justification. This should clearly identify appropriate logical groupings of devices and show the relevant address ranges used by each group.
- Methods used by different devices to acquire their address, with justification.
(10 Marks) (LO2, LO3)
Task 4 – Network Services
Every network depends on the services provided to make it useful. These include obvious foreground user services such as e-mail and less well-known background services such as the Domain Name Service (DNS).
Identify an appropriate set of services (both foreground and background) for the school to run on their network. For each service, clearly explain why it is necessary and how it helps the school either in running their network (background services) or running the school (foreground services). Make sure that you are describing services, not servers or protocols.
Task 5 – Network Monitoring
Identify one specific network monitoring tool that the school could use to ensure that their network continues to perform correctly. You should identify a specific product (including manufacturer, product and exact version or model number as appropriate) including supplier and price. This should be appropriate to the size of the school and their network.
For the tool you have identified, explain what it does by describing different aspects of its functionality, and how the information it supplies can be used by the company. You should support your explanation with screenshots from the product.
Task 6 – Security
As with any computer system, security is an issue with a new network. Identify three possible security issues that the school will face with their new network and outline how they can provide appropriate levels of protection.
(15 Marks) (LO3, LO5)
End of questions
You have the opportunity to submit a draft assignment to receive formative feedback.
The feedback is designed to help you develop areas of your work and it helps you develop your skills as an independent learner.
If you are a distance learning student, you should submit your work, by email, to your tutor, no later than 2 weeks before the actual submission deadline. If you are a blended learning student, your tutor will give you a deadline for formative feedback and further details.
Formative feedback will not be given to work submitted after the above date or the date specified by your tutor – if a blended learning student.
You MUST underpin your analysis and evaluation of the key issues with appropriate and wide ranging academic research and ensure this is referenced using the AU Harvard system. The My Study Skills Area contains the following useful resources:
Guide to Harvard Referencing http://moodle.bl.rdi.co.uk/guides/HarvardRef/AU_Harvard_Quick_Ref_Guide.pdf
Guide to Harvard Citation http://moodle.bl.rdi.co.uk/guides/HarvardRef/AU_Guide_to_Harvard_Citation.pdf
You must use the AU Harvard Referencing method in your assignment.

Assessment Criteria: Level 5
|Level 5 reflects the continuing development in knowledge, understanding and skills from Level 4. At Level 5, students are not expected to be fully autonomous but are able to take responsibility for their own learning with appropriate guidance and direction. Students are expected to further develop their theoretical knowledge within a more intellectual context and to demonstrate this through more complex forms of expression which move beyond the descriptive or imitative domain. Students are expected to demonstrate skills of analysis in both problem-solving and resolution.|
