Microsoft Word - 3.1P Internet Layer.docx Objectives In this task you will demonstrate the work that you have completed and the understanding you have gained from the weeks indicated above. There are three parts to this pass task (questions appear starting on the next page), as follows: • Part 1. Specific Questions – short answer questions requiring you to explain or discuss one several topics examined (page limit: 1 page). • Part 2. Reflection Questions – general discussion where you reflect on what you have learned and demonstrate you have understood the context for the learning conducted (page limit: 1 page). • Part 3. Evidence of Learning – a collection of artifacts you have gathered to demonstrate what activities you have completed in learning the content of the unit (no page limit). Page limits indicated above are based on text that is formatted reasonably, e.g., 2cm margins, 11 or 12 point font, appropriate headings/spacing, etc. If your submission significantly exceeds these limits, either in answer length, by using tiny fonts, no spacing, etc., then your submission will be returned to you without review for corrections. Submitting Your Task Prepare your submission using the word processor of your choice and submit a PDF to OnTrack. Citations and Referencing When completing assessment it is necessary to acknowledge the work of others that you have relied upon. For written submissions, we achieve this using citations and references. Failing to correctly identify the work of others is known as plagiarism, an issue of Academic Integrity, and is subject to penalties. If your submission to this task has involved using the work of others, you must include citations and references where appropriate. Deakin provides a web site that explains how to use citations and references, and includes explanations of various referencing styles: https://www.deakin.edu.au/students/studying/study-support/referencing You may choose any of the styles described on the above site, however you must apply your chosen style consistently for this task (you can use other styles in other tasks if you wish). Note that any bibliography/list of references is not included in page limits. SIT716 Computer Networks and Security Pass Task 3.1P Week 3: Internet Layer Part 1. Specific Questions Your answers to these questions must be your own, however you may discuss these questions with other students and/or your workshop supervisors to get ideas/insights. These questions are not intended to be challenging, in fact you should be answer most of these questions from your knowledge of studying the unit. 1. Draw a diagram that illustrates the network you have at home (wired/wireless), including the connection to your ISP and up to five devices you have connected (use your mobile as a wireless broadband hub if you don’t have a home network). Annotate your diagram to indicate the different networks (subnets) involved. Note: you may use any charting software such as Visio (PC), OmniGraffle/ConceptDraw/Edraw (Mac), or many free alternatives including LibreOffice Draw (multiple platforms), or LucidChart/ draw.io (web-based), and so on. 2. Using a computer connected to the internet a. Use Wireshark to capture your computer pinging a remote web site such as www.deakin.edu.au or www.google.com.au, and copy a screenshot of the breakdown of the ICMP request packet (middle panel) into your answer. b. Open a Command Prompt or Terminal window and display the local ARP cache by entering the command ‘arp -a’ and copy a screenshot of the cache output into your answer. c. Review the IP addresses and MAC addresses displayed in these two screens. From these two screens it is possible to identify the IP address of your router/default gateway. Explain. Note: if you are unable to identify the router/default gateway explain what you are seeing and why the router/default gateway IP cannot be identified. Part 2. Reflection Questions 1. What are the most important lessons you learned in studying this week/these weeks and how will you apply these in your future learning/future career? 2. If you had to explain what you learned to another person/student, what topics do you need to improve your understanding of so you can explain those topics properly? How will you do this? 3. How does this new knowledge fit in with your existing knowledge and how will you use it in your future learning/career? Part 3. Evidence of Learning There are no specific questions to answer for this section. Instead, this section acts like a journal where you gather the evidence of your learning. You can include any elements are relevant to your learning, however if you are aiming for a higher grade this section would naturally reflect more in-depth activities, even going beyond unit content (for HDs). Keep in mind that you are evidencing your learning, so make sure you include a brief discussion/summary where relevant to explain where/what you have learned. Your learning also isn’t restricted to yourself, e.g., you will also learn helping other students understand content. Examples may include: • Notes/summaries you have taken while reviewing the content online or while completing the labs. • Links to web sites / videos you have reviewed to further develop your understanding. Include a brief summary of why this site/video is useful and what you learned from it. If you find something particularly useful, make sure you post it in the forums for others to learn from also! Continued over page à • Discussion postings you’ve made asking questions or providing answers. Include a brief summary of what you learned from the answers you received, why you were able to provide a good answer, or what you learned in contributing to the discussion. • Discussions you’ve had with other students, staff, colleagues, and so on. Include a brief summary of what was discussed and the outcome of the discussions, e.g., did you do additional work after this discussion or did you work with others to solve a problem you discovered? • Experiments you’ve conducted, either as part of the labs in the unit or your own experimentation. What work did you complete and what did you learn? • If you are aiming for a higher grade, your learning would also include preparation for higher tasks, so you can include some notes here as part of that. Your notes here could include a plan of what work you need to do or even a (partial) draft of your answer.
