You will be given feedback via Moodle and have an opportunity to submit additional evidence. For a ‘satisfactory’ result in this task, all sections must be answered to a ‘satisfactory’ standard with a mark of 60% or above achieved.  At Advanced Diploma level a ‘satisfactory’ standard, as stipulated by the Australian Qualifications Framework (AQF), means that you will demonstrate the application of knowledge and skills: with depth in areas of specialisation, in contexts subject to changewith initiative and judgment in planning, design, technical or management functions with some directionto adapt a range of fundamental principles and complex techniques to known and unknown situationsacross a broad range of technical or management functions with accountability for personal outputs andpersonal and team outcomes within broad parameters Where a critical question is identified you must receive a mark of 100% for this question before a ‘satisfactory’ result can be awarded for this task Assessors also make decisions based on the following considerations: All parts of the assessment task/s have been completed to a standard that satisfactorily meets the requirements set out in all of the assessment criteria (as set out in the unit/module outlines).The assessment tasks are the student’s own work, except as appropriately acknowledged by the use of referencing. The evidence is recent and knowledge is up-to-dateThe evidence is consistent showing competency over a period of time suggesting sustained performance (i.e. not just a one off).       Assessment Task Instructions: You must attempt ALL questionsThe best marks can be earned by giving concise brief answers that addresses the questions as put to you.The time indicated is tentative and is not meant to restrict your answersThe main idea behind the use of assignment questions are for you the student to learn and understand the material by reading it and answering the questions as put. Cutting and pasting from internet sites or the study material does not enhance that learning process. However, appropriate diagrams can be pasted if you cannot draw them.Use this document also for furnishing your answers by typing the answers after each question without deleting the question. Use this Microsoft Word document as it stands. Make sure that you preserve the original question number format and that you don’t change the question numbers by adding extra lines or deleting existing ones.Do not add extra pictures, etc. as annexures but add the pictures and diagrams directly into this main answer sheet by pasting. Hand-drawn sketches can be inserted after scanning but please ensure that the assignment file size does not become big (more than 10 MB).Refer in the text to diagrams and pictures etc that you have drawn or pasted in. Do not only paste them into the document without referring to them in the text.Finally when saving your document (must be WORD FORMAT), ensure you save the title to include your name: COURSECODE_MODULE#_ASSIGNMENT_VERSION#_YOURNAME E.g.

Module 17: Practical Wireless Ethernet and TCP/IP Networking Practical Assessment Total Marks: 150 marks Assessment Points: Supply the required answers below in a blue font (not red or black).You must submit this assessment along with the written component.Answer all the questions. Instructions Please follow instructions here for accessing the Remote Labs.Wireshark is installed on the Remote Labs (instructions here) or can be downloaded and installed on your own computer, free of charge.For an introduction to Wireshark, see this Wireshark Tutorial for Beginners. Set-up and run Wireshark to capture 3 types of traffic on your LAN interface: TypeTargetDescriptionALink LocalPing your own device at 127.0.0.1BLocal LANPing a device within your local IP address rangeCNot on local LANPing a device which is NOT within your local address range. Use the URL www.eit.edu.au. Filter specifically for the protocol that is used for the Ping command and capture all lines pertinent to the above three Ping commands. Note: Where applicable, only expand the header on Wireshark until it is three lines long, please do not expand the mac addresses further. Keep the questions below in mind. Q1General knowledge about the Ping command What is the full name of the protocol that the Ping command uses? (1 mark) What is the acronym commonly used in industry of the protocol that the Ping command uses? (1 mark) What is the type of request that the ping command sends from the host to the target, called? (1 mark) The host that originally sent the ping command to the target, waits for a specific kind of frame to return. What is it called? (1 mark) Name three indications that the Ping utility produce. (3 marks)(7 marks)A1Student AnswerF1Assessor Feedback(marks awarded)Q2Ping command on the Link Local address (127.0.0.1)In respect of Ping type A (on Link Local address): Produce a screenshot of the Ping results. (3 marks)For the latency observed on the local address, what is the: (7 marks) Minimum? (1 mark) Maximum? (1 mark) Average? (1 mark) Is it possible for the latency (delay time) to be zero? Explain? (2 marks) Calculate the hop-count. What is the TTL and the number of hop-counts respectively? (2 marks)(10 marks)A2Student AnswerF2Assessor Feedback(marks awarded)Q3Ping command on an IP address native to your LAN Tip: You will need ping a device on your LAN address range. There is no standard address that we can supply here, but you will find the address of your PC and some devices in its vicinity (i.e. on the same LAN) in the Arp -A screen.In respect of Ping type B described above, produce screenshots showing the results of the: Arp -A command (2 marks) Appropriate interface data on the Ipconfig /all command (2 marks) Ping command and (2 marks) relevant Wireshark packet trace of the Ping operation. (2 marks) Apply your theory to the captured data to prove that the IP address for the Ping command, is within your devices’ local area network IP range. (5 marks)For the latency observed on the local address, what is the: Minimum? (1 mark) Maximum? (1 mark) Average latency observed? (1 mark) Calculate the hop-count. What is the TTL and the number of hop-counts respectively? (2 marks) Are the data obtained for latency and hop-count realistic? (2 marks)(20 marks)A3Student AnswerF3Assessor Feedback(marks awarded)Q4Ping command on an IP address outside your LAN (www.eit.edu.au)In respect of Ping type C described (4 marks): Produce screenshots showing the results of the Ping command. Produce screenshots showing the relevant Wireshark packet trace of the Ping operation.Hop count (6 marks): Determine or calculate which IP address the URL resolved to (1 mark) How many hops were traversed in reaching the target (2 marks) Compare the hop count found in question 3 with the one above. Discuss whether you think the hop-counts are realistic. Explain your answer. (3 marks)Latency / turn-around delay (10 marks): Detemine the minimum (1 mark), maximum (1 mark) and average turn-around time? (1 mark) Compare the average turn-around trip time found in question 3 with the one immediately above. Discuss whether you think the turn-around trip times are realistic and why you say so. (2 marks) Apply your theory to the captured data to prove that the resolved IP address is NOT within your devices’ local IP address range. (5 marks)Once it is proven that the target IP address is not part of your local LAN IP address range, packets are sent to another specific IP address. (10 marks) What is the device called where the packets are then sent to? (1 mark) What is its address in your case? (1 mark) How and where did you find this specific address? (1 mark) Explain how the URL got resolved to an IP address in theory and what the relevant servers are calls? (3 marks) What are the adresses listed for the servers in the above question? (2 marks) To support your explanation, provide a screenshot of only the relevant part of your Wireshark screen, showing the URL to IP address resolution.
