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 text book 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]

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 document 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 your 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 XXXXXXXXXXprivate IP address.Your designed network should span six sites with a router at each site to interconnect the entire network.

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

Rationale

This assessment aims to assess the following learning objectives of this subject:

  • be able to analyse IP addressing requirements and design an addressing scheme;
  • be able to analyse the requirements of IP routing and choose appropriate routing methods;
  • be able to demonstrate how internetworking devices obtain their network configuration;
  • be able to explain how data flows through the internet; and
  • be able to ascertain and evaluate selection of applications and protocols for transferring data across the internet.

Q1. 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?
Sol:-
The difference between OSI (Open System Interconnection) and TCP/IP (Transmission Control Protocol/ Internet Protocol) network models are presented in given below table.  ("Difference between OSI Reference Model and TCP/IP Reference Model | Studytonight", 2018).
    OSI
    TCP/IP
    OSI is a protocol independent standard. It is gateway between the network and end users of the communication
    TCP/IP is protocol dependent standard. This allows the connection of host over the network
    There are seven layers in the OSI model
    There are only 5 layers. The Application, session and presentation layers are combined together under application layer.
    Transport layer of OSI model guarantees the delivery of the packets source to destination
    Transport layer of TCP/IP does not guarantees the delivery of packets to source to destination
    OSI model follows the vertical approach of the communication
    TCP/IP model follows the horizontal approach of the communication
    In OSI transport layer provides only the connection oriented service
    In TCP/IP transport layer provides both connection oriented and connectionless services
    In OSI reference model the network layer or Internet Layer provides both connection oriented and connectionless services
    In TCP/IP model the network layer provides only the connectionless service
    The protocols under the OSI reference model are hidden and also be changed by change in the technology
    The protocols of the TCP/IP model is not hidden and also cannot change with the change in technology
    There are definitions of the services, interfaces and protocols in the OSI reference model
    There are not definitions of the services, interfaces and protocols in the TCP/IP model
    The fitting of the protocol under the OSI reference model is a problem
    The fitting of the protocols in TCP/IP model is not taken
    OSI reference model is less reliable model than that of the TCP/IP model
    TCP/IP model is more reliable than that of the OSI reference model
    The network connection is process of the bottom to upper layers in the OSI reference model
    The network connection is the process of upper to bottom layers in the TCP/IP model
    OSI reference model is more complex model of the network communication standard
    TCP/IP is simple model of the network communication standard
    OSI is a reference model
    TCP/IP is implementation model
Above mentioned comparisons between the OSI and TCP/IP models are major differences with respect to the standards and functional aspects.
Q2. Complete the following Hands-On Projects from the prescribed textbook (Pyles, Carel & Tittel 2017)
· Hands-On Project 2-3
· Hands-On Project 2-5
Sol:-
Hands-On Project 2-3
The steps are taken as follows
· Open the bitcricket IP subnet calculato
· Select the address bar and input the given IP address 192.168.0.0.
· Select the subnet mask combo box and select the mask 255.255.255.248 (/29)
· Now click on subnet tab.
· Finally 32 subnets for given IP 192.168.0.0 is created.
The screenshot is as follows.
Hands-On Project 2-5
Search and retrieval of RFC 4291 from ietf.org website.
Full 25 pages view to read from page 1 to page 25 of RFC 4291 in pdf view.
