This should be submitted via Turnitin on Moodle asa word-processed document file.Kind reminder: You MUST make a reasonable attempt at yourassignment and submit it. Failure to do so may result in CAPPED Resitand/or failure of the module.It is also the students’ full responsibility to ensure that all assignments aresubmitted on the correct link and on time before the submission date. 2 | 8 © 2019 Roehampton UniversityRationaleThis is an individual assignment based on the case study scenario presented below(recommended maximum words: 2500 words). This assignment will assess yourunderstanding of the principles of network design and the ability to analyse, design andcreate a network infrastructure fully configured and tested which will reflect yourunderstanding of network design and troubleshooting.Assignment supportAlthough your lecturer will guide you throughout the module, extra support is also availablefor your assignment, just make an appointment with the ACE team for any language,research and study skills issues and/or talk, email the Computing ACE expert for anyadvice on how to approach your assignment. REMEMBER: they are not here to give youthe answers!3 | 8 © 2019 Roehampton UniversityAssignment TaskScenarioYou are working as a network engineer for qfix.co.uk, your company contracted a thirdparty company to design and implement network for their new branch in London.Below is the third party company network infrastructure design including recommendationsubmitted to qfix.co.uk which includes the network floor diagram, network topology asexpressed in figure 1 and 2.Figure 1: Existing network floor diagramFigure 2: Proposed Network topology4 | 8 © 2019 Roehampton UniversityThe third party company decided that there is no need to allocate a room specifically for theserver, as each department will keep their server close to the users as possible for ease ofmanagement. In other words, Admin server will be close to the admin users and so on. Thebackup is carried out in main fileserver using an external hard disk, which is stored in alocked cabinet next to the server.Based on the number of users, the third party company decided that there is no need tosegment the network as there is a limited number of users and hence there will be no largebroadcast domain. However, the company director expressed some concerns and askedyou to evaluate the third party network solution and design a new solution.qfix.co.uk uses private network address of 192.168.14.0/24, and a public IP address of220.221.222.160/28. Security, availability and scalability are paramount, hence your designand configuration must be based on these criteria.Table 1 shows the users distribution and requirement according to qfix.co.uk’s policy.

NOTE: All computers will use a Microsoft product such as servers and workstations. LAN Network needs to be physically redundant at least at wiring / Switches level.5 | 8 © 2019 Roehampton UniversityDeliverablesThe network given in the above scenario may have many areas of network securityconcerns, you are to perform the following task and provide the following:A. Evaluate the given network design in terms of security, availability and scalability.Your evaluation should include discussions of potential security impacts on the givennetwork.B. With the aid of diagram, design a new secured and reliable network. Your networkdesign should include:o Analysis and evaluation of topology used including Network documentation(topology documentation, devices configuration tables and end devicesconfiguration table).o Analysis and evaluation of devices, protocol and technologies used.o Network security consideration.o Sample related configuration of switches, routers should be discussed in theassignment bodyo Produce a test report on all network including web, email and dns serversfunctionality and connectivity across all network including to/from DMZ.o Include network simulation file in your assignment appendices.6 | 8 © 2019 Roehampton University Assessment criteria / Marking schemeAssessmentCriteriaAssessment CriteriaIntroductionIntroduction6Introduction to the context and/or background to the topic, indicatingthe purpose of the report.10Marks4The introduction includes some definitions of complex terminology oracronyms indicating ideas in view of the conclusion of the report.Knowledge andunderstandingKnowledge and understanding6Demonstrate effective approach to study and research includingexplanation and discussion of subject concepts, exploring requirementsof given assignment.10 Marks4Using relevant information paraphrased / interpreted from soundsources, summarising and making sense of information.Application andAnalysisApplying knowledge and analysis7Discussion, examination and analysis of different network components,exploring the relationship between different components eg: topologyused including Network documentation (topology documentation,devices configuration tables and end devices configuration table).15 Marks5Reasoning of device/components selection based on prior-knowledge,backed by evidence of research from academic sources.

In other words, plagiarism, collusion (working andcopying from another student) and ghost writing will not be tolerated and will result in sanctions eg:capped resit, suspension and/or withdrawal. Correct referencing demonstrates your academic andprofessional skill. It also reflects your academic honesty and thus to some degree protects you fromcases of plagiarism. You must write your assignment in your own words to demonstrate your understanding of the subject.Material from external sources must be properly referenced and cited within the text using the Harvardreferencing system,You are required to follow the Roehampton Harvard referencing System. Please refer to Moodlefor the latest version of the Roehampton Harvard referencing System or ask the library.An accompanying list of references (on a separate page and in alphabetical order) must also beprovided as part of your work.Plagiarism: occurs when you present somebody else’s work as your own, whether that work is an idea,graphs, figure, illustration or a pure text. Be it available in web, textbooks, reports or otherwise.Wholesale use of text and diagrams from websites is considered as plagiarism when notacknowledged.Plagiarism will be dealt with firmly and can lead to serious consequences and disciplinary procedures.Collusion: occurs when copying another student’s report (Text, Figures, Illustration etc..) andsubmitting it as your own. Submission and Late submission Students must ensure that their work is satisfactory and fit for purpose, both academically and freefrom any plagiarism.Students must use an appropriate coversheet, which must include the subject, assignment title,student ID and date-time.Tutors, lecturers and module convenors do not have the authority to extend the submission deadlinesnor the exam time/date. In case of any mitigating circumstances, students should fill in the relevantmitigating circumstances form(s) available at —— Student Services —–The marking of the assignment will be capped at 40 if the assignment is submitted within first seven(7) days after the deadline, any submission late than 7 days will be ignored.The Submission File should be appropriate to the topic/title of the assignment and contain the StudentID, (Student ID-Assignment title)All coursework related material must be attached as an appendix in the final coursework/assignment document, including any computer-generated document, software/ code, simulation file etc..
