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 subject. 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 textbook and any additional material you have used 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 though the final answer is wrong.

Question 1  [3 Marks]

Briefly describe the OSI reference model and the TCP/IP networking model, use diagrams to show the relationship between both these models.

Question 2   [3.5 Marks]

Complete the following Hands-On Projects from the prescribed textbook (Pyles, Carel & Tittel 2017, pages 37-45)

• Hands-On Project 1-1
• Hands-On Project 1-2

In order to complete this activity, students should insert screenshots in the assignment document along with a short description of each step taken to complete the project. Students must also answer any relevant questions highlighted in step-by-step description of the above mentioned hands-on projects in the textbook

Question 3       [3.5 Marks]

1.     a. Describe the role ARP Cache plays in establishing Address Resolution Protocol (ARP)? [2 Marks]
2.     b. Complete Hands-On Project 4-1 from the prescribed textbook (Pyles, Carel & Tittel 2017,page 241) [1.5 Marks]

Question 4  Case study task        [5 Marks]

In your role as a Solutions Architect at Riverina IT Solutions, you are leading a team of several system administrators. Riverina IT Solutions is a medium sized organisation and is currently expanding its operations. The company has acquired six sites across regional New South Wales to accommodate its various departments. You have been asked to design a network by utilising 10.0.0.0 private IP address. The 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 1100 workstations across all the sites with approximate numbers in each building as follows:

Wagga Office – 300 workstations

Junee Office – 130 workstations

Albury Office – 125 workstations

Griffith Office – 120 workstations

Temora Office – 215 workstations

Culcairn Office – 150 workstations

TASK – Write a 800 words (+/- 10%) (Max) report explaining:

3. 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 jumps to over 1,024 per building. [ 1.5 Marks]
