This assignmentwill assess your understanding of the principles of network design and the ability to analyse, designand create a network infrastructure fully configured and tested which reflects understanding ofnetwork design and troubleshooting.ScenarioYou are working as a network engineer in an IT company. You have been assigned to design,implement a network infrastructure for a small company donow.co.uk. The company consist of 4departments (finance, engineers, sales and IT).The network consists of three Servers: web-dns, email- IoT, and common File Server as describedin the table below. All servers are shared between all users. The distribution of workstations, shownin table 1, describes the requirement of each department. The company has decided to allowmembers of staff to use the wireless network on their own wireless device such as smartphone toaccess the internet.

Table 1: workstation and server distribution and requirementsThe IT director emphasised on scalability and availability, hence you are being required to provide acomplete network infrastructure design and implementation. The company will be using privatenetwork IP address 192.168.44.0/24 within wired LAN, and 10.20.44.0/24 for the wireless network.TaskAnalyse the requirements given in above scenario evaluating suitable network models andcomponents to design a network infrastructure featuring scalability, availability and security.Based on your analysis and evaluation, you are to: Apply the required configuration for the selected components. 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, networksimulation file must be included and attached as appendix.3 | 6 © 2019 Roehampton UniversityDeliverables Complete network diagram for the given scenario, including description and analysis. Appropriate subnet showing all required elements, based on given network addresses, arefulfilled. Create VLAN for each department based on given requirements, including sampleconfiguration. Justification of the use of network design model and components including anytechnologies/protocols used such as VTP, STP, DHCP etc.. Provide complete security precaution and configuration where applicable including Accesscontrol list to isolate each department internally. Complete testing documentation of all relevant devices such as web, email, DNS servers,(note: use of screenshots without description is not acceptable as answers)Word countDon’t exceed the word countYou need to state the word count at the end of their assignment. 10% over the stated word count ispermitted without penalty.If students go beyond this, then there is a penalty of 5 marks for every additional 10% beyond theword count with a maximum of a 15 mark penalty reduction.There is no specific penalty for submitting a piece which is below the word count, but please notethat shorter submissions are likely to attract poorer grades, particularly where they lack thenecessary depth of analysis.How do you calculate the word count?The word count includes the Abstract or Executive Summary and all in-text citations. The wordcount does not include the Bibliography and Appendices.Please note that Appendices should only include supplementary information, not informationcritical to your work.4 | 6 © 2019 Roehampton University Assessment criteria / Marking schemeAssessment CriteriaDescriptionIntroductionIntroduction6Introduction to the context and/or background to the topic, indicating the purpose of the report10Marks4The introduction includes some definitions of complex terminology or acronyms and indicatesideas in view of the conclusion of the report.Knowledge andunderstandingKnowledge and understanding6Demonstrate effective approach to study and research including explanation and discussionof subject concepts, exploring functional and non-functional requirements of the givenassignment10 Marks4Use relevant information paraphrased / interpreted from academic sources, summarise andmake sense of informationApplication andAnalysisApplying knowledge and analysis7Discussion, examination and analysis of different network components, exploring therelationship between different components15 Marks5Reasoning of device/components selection based on prior-knowledge, backed by evidence ofresearch from sound sources3Discussion and analysis of different network modelsEvaluation andjudgementEvaluation of different components and network model8The judgment in selecting components shows understanding of issues based on evaluatingand comparing different network components supported by literature15 Marks7Evaluation of different technologies and/or protocols such as VLANs, Trunking, Accesscontrol, DHCP etc.Design andImplementationNetwork implementation and design10A description of network diagram, summarising the network design, including implementationand configuration of all network components and protocol with evidence (sample networkconfiguration scripts).20 Marks6The plan accommodates the necessary devices and accounts for the unforeseeableconditions.4Evidence related to the work is carried out in designing.
