Solution
Assignment Overview: The assessment focuses on the concept of internetworking with TCP/IP. It undergoes comparison of various models and selecting on the basis of usability. The assignment also contains the hands-on projects that are taken as exercise from the learner’s course book (Pyles, Carel & Tittel 2017). A complete ARP discussion focussing on purpose of ARP cache. Apart from this, a case study is analysed to provide the company addressing scheme that fulfil the requirement of the organization. The task wise description of the whole assessment is provided underneath;
Task 1: The task emphasizes on the comparison of the OSI reference model with the TCP/IP networking model. The task will cover all the important aspect such as layers, working and origin of these models. Meanwhile, the task will cover which model is best and useful when working and explaining networks.
Task 2: This task is about the Hands-on Project 2-3 & Hands-on Project 2-5 that are provided in the form of exercise in chapter 2 of student’s course book i.e. Pyles, Carel & Tittel 2017.
Hands-on Project 2-3: To calculate the Subnet Mask for a required number of IPv4 Subnets. The activity includes main objective to determine the subnet mask with the help of using an online IPv4/IPv6 subnet calculator. A total of 10 minutes is to be spent on the activity.
Hands-on Project 2-5: The activity focuses on the important traits of the network such as host address range, broadcast address, CIDR, Network address and many more with the help of provided online website www.subnet-calculator.com. It also includes calculation of maximum subnets automatically.
Task 3: The task focuses on the ARP (Address Resolution Protocol) which works below the network layer i.e. on data link layer. The task will also cover the purpose of ARP cache.
Task 4: This is the final and important task of the assessment that undergoes a case study regarding Foreshore IT Solutions with a capacity of 1200 workstation. As a Solution Architect, one need propose a solution that will cover the addressing of all 1200 workstations and will also provide expandability in case of further expansion that is presumed for future. The addressing scheme will cover all the buildings like
Finance Office - 260 workstations
IT Call Centre - 520 workstations
Research and Development Office - 120 workstations
Marketing Department - 40 workstations
Information technology - 130 workstations
Head Office - 60 workstations
This task is further divided into two subtasks;
a) To provide a complete addressing scheme which must be simple and will be done using VLSM. Apart from this, a complete diagram along with all the buildings are designed to show how the devices will actually behave within the network.
b) This subtask will include all the calculations of additional 1024 hosts that can be presumed to be increased per building.
Referencing: None but not the least, the document will be concluded with referencing which is strictly followed as per http://student.csu.edu.au/study/referencing-at-csu. The referencing style will be APA and the bibliography will be such that it would support the document in wise manner.
AA Assessment Task
This assessment aims to develop and gauge student understanding of the key topics covered so far by
answering the following questions. Answering these questions will help you build some understanding for the
next assessment item as well as for the entire s ubject. It is expected that answers to the assignment questions
be succinct (i.e. precise and concise) with all sources of information fully referenced as per APA referencing
style. You have to reference the text book and any additional material you have u sed in your answers.
Note that the guide for APA referencing is provided in the resources section of Interact site of this subject.
Answers MUST be written in your own words. No marks will be awarded for any answer that contains more
than 10% direct quote (referenced or unreferenced). One or two sentence answers will be too short and only
receive low marks. Answers longer than 1.5 pages (12 point font, single line spacing) may incur a penalty if too
much non -relevant information is stated. For mathematical questions it is expected that you show
intermediate steps of your working. Just stating the correct solution will result in low marks, on the other hand
if the working is correct and you only made minor mistakes, you will still be awarded marks, even thoug h the
final answer is wrong.
Question 1 [3 Marks]
Compare and contrast the OSI reference model with the TCP/IP networking model. Which one do you think is
more useful when working with and describing networks and why?
Question 2 [3.5 Marks]
Complete the following Hands -On Projects from the prescribed textbook (Pyles, Carel & Tittel 2017)
Hands -On Project 2 -3
Hands -On Project 2 -5
In order to complete this activity, students should insert screenshots in the assignment do cument along with a
short description of each step taken to complete the project.
Question 3 [3.5 Marks]
Briefly describe the Address Resolution Protocol (ARP). What is the purpose of the ARP Cache?
Question 4 Case study task [5 Marks]
In yo ur role as a Solutions Architect at Foreshore IT Solutions, you are leading a team of several system
administrators. Foreshore IT Solutions is a medium sized organisation and is currently expanding its
operations. The company has acquired six sites across Adelaide to accommodate its various departments. You
have been asked to design a network by utilizing 10.0.0.0 private IP address.Your designed network should
span six sites with a router at each site to interconnect the entire network. It is assumed that each site will
have its own single subnet. Company expects approximately 1200 workstation across all the sites with
approximate numbers in each building as follows:
Finance Office - 260 workstations
IT Call Centre - 520 workstations
Research and Developmet Office - 120 workstations
Markeing Department - 40 workstations
Information technology - 130 workstations
Head Office - 60 workstations
TASK - Write a 800 words (+/ - 10%) (Max) report explaining:
a.The detailed design of a simple addressing solution (with diagram(s) and step by step workout of the
calculations) that leaves room for growth, is easy to administer and has the minimum wastage of available IP
address space. [ 3.5 Marks] b.Explain what happens to your design if the number of hosts per network ju mps to over 1,024 per building. [
1.5 Marks]
Rationale
