Pearson BTEC Level 5
HNC/D Diploma in Computing and Systems
The date for Submission: 14th May 2015
(The submission portal will close at 13:59 BST)
Set by: Dr. Adrian J Pullin
As part of the formal assessment for the HNC/D program, you are required to submit an assignment for each module. Please refer to your Student Handbook for full details of the program assessment scheme and general information on preparing and submitting assignments.
After completing the module you should be able to:
- 1.Understand the principles of network infrastructure management.
- 2.Design complex network infrastructure systems
- 3.Implement complex network infrastructure systems
- 4.Test complex network infrastructure systems.
Completing the assignment tasks will demonstrate your ability to do these things. Specifically, each part of each task corresponds to the relevant assessment criterion given at the end of this specification. E.g. task 1 part 1 corresponds with Assessment Criterion 1.1.
Resource Development International claims to be the largest commercial provider of UK Higher
Education qualifications in the world. RDI provides courses leading to HND, bachelor‟s and master‟s degrees in a wide range of subjects including Business Studies and of course Computing. RDI has students from over 150 countries, of all ages and walks of life.
RDI’s head office is based in the city of Coventry in the West Midlands county of England. Most of the non-academic staff work at head office on conventional working hours, with conventional office facilities and IT infrastructures. Academic tutors mostly work remotely from the office, connecting in via the Internet as required to pick up e-mail, develop materials on iLearn, and process marking.
The entire network is built on Microsoft‟s Windows servers running Active Directory. All employees have AD user names and passwords which give access to the required services at head office, either directly or via the Internet.
Note: RDI is (obviously!) a real company and most of the information in the scenario is broadly accurate to the real company. However, reality has been altered and simplified to make the scenario better fit an assignment specification. Please do not try to contact anyone at RDI (apart from the module tutor) to seek further details about the company structure. If you have any questions about the assignment or the scenario, contact the tutor.
Task 1 –Guideline length 800 words
1.1 As an RDI Tutor, I need to visit their web site regularly to keep up to date with activities. To do this I go to the RDI website www.rdi.co.uk using a popular browser such as Microsoft Internet Explorer or Mozilla Firefox.
Assuming the YOU are doing this from your own computer where you normally do your RDI studies, provide a detailed description of how RDI‟s Domain Name Service (DNS) name (www.rdi.co.uk) is resolved into an IP address so that the request can be sent to the server. You should include the following:
a)A description of how the DNS lookup works, using this particular case as an example. Your answer must be detailed and specific, mentioning as appropriate both RDI, its DNS server, its website, and your own Internet Service Provider‟s DNS service as well as any other DNS servers used.
Assume that RDI runs its own DNS server.
b)The full result of doing a DNS lookup on this particular address together with an explanation of all the items in this result. Note that there are many DNS lookup tools available either to use directly from web pages or to download and use locally.
1.2 Briefly explain the purpose of the following components in the organization ‟s network:
- •Domain Controller (DC)
- •Wireless access point
1.3 Outline how the organization would use a firewall to protect its network.
You are advised to draft your answer to task 1 within the first month of the module and send it to the tutor via e-mail (with your full name, student id, and the module name) for comments and feedback. This will help you make sure that you are on the right track.
Task 2 –Guideline length 800 words
RDI has a number of departments including ARU Support (supporting students on ARU degree programs), Wales Support, Pearson Support, Admissions, IT Support, and Tutors.
Each support department has ahead of the department in charge with a number of staff working under them. The tutors are divided into teams based on the course on which they tutor and headed by an Academic Award Director.
For each of the following, you must provide the actual design or structure asked for, together with an explanation of your structure explaining how it fulfills the requirements given. You may make reasonable assumptions to cover the lack of detail in the scenario but these must be clearly stated and justified.
2.1For the organizational structure given, draw an organization diagram to be used in developing the required directory structure. Using your organization structure, devise a directory structure using Microsoft Active Directory as the target. You should look up Active Directory diagrams to see how they should be presented. You should include a written explanation of the design you present. Note that TWO diagrams are required: the organization structure and the Active Directory design.
2.2Within your directory structure, identify the groups that can be used to allocate access rights to staff. Make sure that you discuss groups and NOT organizational units.
2.3For this Active Directory structure, devise file storage (i.e. folder) structure that will allow appropriate people to access appropriate files and for this to be controlled using the access rights and groups. Include a diagram showing the overall folder structure and notes explaining how access rights are used to control who can access and change an example file in an example folder from your design.
Task 3 –Guideline length 600 words
Outline how you would implement the Active Directory (AD) structure devised in task 2. You should provide the implementation information, explanations, and justifications to show how your solution fulfills the requirements of the organization. You should cover the following:
a)Identify appropriate objects including users, end-user computers, printers, and servers for one department in the structure. As mentioned in task 2, each department has a head of the department in charge with a number of section leaders and staff working under them.
b)For each of these objects, identify the AD attributes of that object in detail, matching against the standard schema for that type of object. Provide an example set of data that can be used to populate each object. You can make up appropriate names and other details for each object.
A table of information (in landscape layout) would be an appropriate way to present the information for tasks 3a and 3b. It should show examples (say 2 or 3 of each type) not a full data set.
c) Briefly explain how you would implement the domain controller system, including how many DCs you would have, how they would be related to each other, and physically where you would site them.
This task 3 covers the single assessment criterion in this section, 3.1.
Task 4 –Guideline length 900 words
Your newly designed and implemented system must be tested before it becomes the production system at the organization. This is a “mission-critical” system whose operation directly impacts the day to day business of the organization.
Produce a detailed test plan that will demonstrate that ahead of the department has access to all the required facilities within the system. Include the tasks to be done during the tests and (made up) appropriate test results together with comments and appropriate actions. A new system never works correctly and the complete the first time so some of the tests should fail, with appropriate problems and suggested fixes included.
This should test:
- a)logging in
- b)access to the head of the department‟s private files (i.e. only available to this person).
- c)access to the department‟s records, which should be available to all staff in the department.
- d)access to appropriate network resources such as printing.
A table of the tests done and the results of those tests (in landscape layout), with comments and if required actions would be an appropriate way to present this information.
The tests you discuss cover assessment criterion 4.1.
The documentation of the testing covers assessment criterion 4.2.
1.You should write each task of this assignment as detailed above, in the order given above, and clearly labeled with the task and subtask numbers used above (Task 1.1, Task 1.2, etc.). The assignment should be incoherent and appropriate English, complete with citations in the text and a list of references in Harvard notation.
2.You must ensure that the submitted assignment is all your own work and that all sources used are correctly attributed. Penalties apply to assignments that show evidence of academic unfair practice. See the Student Handbook which is in the Induction Area for more information. Please also refer to the
„Guide to Unfair Practice in Assessment‟ on the module page on learning.
3.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 Harvard system. The „My Study Skills‟ area on iLearn contains the following useful resources; Study Skills Guide (containing a Harvard Referencing section) and a Harvard Referencing Interactive Tutorial. You must use the Harvard Referencing method in your assignment. All your answers must be directly related to and focused on the scenario. Generic responses will score very poorly.
4.You should use diagrams and tables of figures where appropriate ensuring to reference their source using the Harvard Referencing method.
5.It is advised that you write your assignment within approximately 3500 words in order for your research and summarising skills to be developed, and for effective time management. You are required to ensure that the assignment addresses ALL of the assessment tasks. There is no penalty for being over the suggested word count, however, in the interests of good academic practice, assignments submitted with excessive word counts (e.g. over 4000 words) may be returned to students and asked to be reduced before marking.
The word count excludes the title page, reference list, and appendices. Where assessment questions have been reprinted from the assessment brief these will also be excluded from the word count. ALL other printed words ARE included in the word count. Printed words include those contained within charts and tables.
6.Your assignment should be submitted as a single document. For more information please see the
“Guide to Submitting an Assignment” document available on the module page on iLearn.
7.As well as submitting a draft of task 1 within the first month of the module for feedback, you are also advised to submit a full draft of the complete assignment to the tutor via e-mail (with your full name, student id, and the module name) for comments and feedback prior to submission. This should be done at least a week before the deadline so that you have time to make any suggested changes.
