ASSESSMENT DESCRIPTION:

Training Plus Network Description

Training plus is an IT training provider in Sydney. Training plus wants to open a new training centre in New Castle. You have been appointed as Network Administrative Officer for Training plus New Castle branch. Training institute will use 2 levels of the building.

There will be no remote users. The computer network is connected to the high speed Internet. All of their computers are desktop machines and are connected with wired Ethernet connections. All of the network wiring is CAT-6 twisted pair wiring that goes from the office location to a wiring cabinet. There is one wiring cabinet on each floor. Each cabinet is connected to the basement wiring cabinet via fibre.

The requirement for the wireless network is the following –

  • Each floor needs to have two wireless access points, one for the east end of the building, and the other for the west.
  • The wireless access points will overlap in the middle of the building, so you need to pick different wireless network channels for each end.
  • On the first floor, there should be an additional wireless access point in the conference room.
  • The “guest” network should have a different SSID than the institute’s wireless network. It should be configured

to allow anyone to connect, with a password.

You have been advised to use one network address and create necessary subnetworks for training, administrative and wireless network.

Training department will have 4 classrooms each with 25 computers. Administrative and IT department will have 20 employees each using their own computer. There will be a wireless network for institute students which can accommodate 60 hosts maximum. The “guest” network should have maximum 30 users.

Now, your role as Network Administrator to propose a network design to suit for this setup. In order to develop your network design, you may need to make reasonable assumptions.

Your objective is to prepare and submit report on the following topics:

Topic-1

Select an appropriate IP range for the institute and calculate the appropriate IP subnets. Calculate the subnetwork in such a way so that there is minimum waste of the IP addresses.

Create a table and show all the IP subnets with network address, subnet mask and users for each subnet.

Topic-2

  • Prepare and draw the network diagram for this office setup. Mention all network devices clearly (like workstations, routers, servers, etc.) in the diagram.
    • Allocate appropriate IP address for all network devices in the network diagram.

Topic-3

Discuss desktop and server operating system types are feasible for this setup. Explain with logic why do you choose each operating system.

Topic-4

Provide appropriate Network Security Solution and wireless LAN security to protect from cyber threat of this company.

ASSESSMENT SUBMISSION:

The assignment must be submitted online in Moodle. Where additional documents need to be attached, all materials MUST be submitted electronically in Microsoft Word format. Other formats (e.g., pdf or MAC file) may not be readable by markers. Please be aware that any assessments submitted in other formats will be considered LATE and will lose marks until it is presented in MS Word. No paper based or hardcopy submission will be accepted.

GENERAL NOTES FOR ASSESSMENT TASKS

Content for Assessment Task papers should incorporate a formal introduction, main points and conclusion.

Appropriate academic writing and referencing are inevitable academic skills that you must develop and demonstrate in work being presented for assessment. The content of high quality work presented by a student must be fully referenced within-text citations and a Reference List at the end. Kent strongly recommends you refer to the Academic Learning Support Workshop materials available on the Kent Learning Management System (Moodle). For details please click the link http://moodle.kent.edu.au/kentmoodle/mod/folder/view.php?id=3606 and download the file titled “Harvard Referencing Workbook”. This Moodle Site is the location for Workbooks and information that are presented to Kent Students in the ALS Workshops conducted at the beginning of each Trimester.

Kent recommends a minimum of FIVE (5) references in work being presented for assessment. Unless otherwise specifically instructed by your Lecturer or as detailed in the Unit Outline for the specific Assessment Task, any paper with less than five (5) references may be deemed not meeting a satisfactory standard and possibly be failed.

Content in Assessment tasks that includes sources that are not properly referenced according to the “Harvard Referencing Workbook” will be penalised.

Marks will be deducted for failure to adhere to the word count if this is specifically stated for the Assessment Task in the Unit Outline. As a general rule there is an allowable discretionary variance to the word count in that it is generally accepted that a student may go over or under by 10% than the stated length.

GENERAL NOTES FOR REFERENCING

References are assessed for their quality. Students should draw on quality academic sources, such as books, chapters from edited books, journals etc. The textbook for the Unit of study can be used as a reference, but not the Lecturer Notes. The Assessor will want to see evidence that a student is capable of conducting their own research. Also, in order to help Assessors determine a student’s understanding of the work they cite, all in-text references (not just direct quotes) must include the specific page number(s) if shown in the original. Before preparing your Assessment Task or own contribution, please review this ‘YouTube’ video (Avoiding Plagiarism through Referencing) by clicking on the following link: link: http://moodle.kent.edu.au/kentmoodle/mod/folder/view.php?id=3606

A search for peer-reviewed journal articles may also assist students. These type of journal articles can be located in the online journal databases and can be accessed from the Kent Library homepage. Wikipedia, online dictionaries and online encyclopaedias are acceptable as a starting point to gain knowledge about a topic, but should not be over-used – these should constitute no more than 10% of your total list of references/sources. Additional information and literature can be used where these are produced by legitimate sources, such as government departments, research institutes such as the National Health and Medical Research Council (NHMRC), or international organisations such as the World Health Organisation (WHO). Legitimate organisations and government departments produce peer reviewed reports and articles and are therefore very useful and mostly very current. The content of the following link explains why it is not acceptable to use non-peer reviewed websites (Why can’t I just Google?): https://www.youtube.com/watch?v=N39mnu1Pkgw
