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 of the next assessment items 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 the 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 [2 Marks] What is a link-layer frame? A network layer datagram? A transport-layer segment? an application-layer message? Question 2 [2 Marks] Is it possible for an application to enjoy reliable data transfer even when the application runs over UDP? If so, how? Question 3 [3 Marks] Consider a router that interconnects three subnets: Subnet 1, Subnet 2, and Subnet 3. Suppose all of the interfaces in each of these three subnets are required to have the prefix 223.1.17/24. Also, suppose that Subnet 1 is required to support at least 60 interfaces, Subnet 2 is to support at least 90 interfaces, and Subnet 3 is to support at least 12 interfaces. Provide three network addresses (of the form a.b.c.d/x such as 223.1.17/24) that satisfy these constraints, and how the steps of how to obtain your answers. Question 4 Case study [8 Marks] In this problem, you need to put together what you have learned about Internet protocols. Suppose you walk into a room outside CSU campuses, connect to Ethernet, and want to download Slides published in a Web page of the ITC 542 site in Interact 2. What are all the protocol steps that take place, starting from powering on your PC to getting the CSU Web page? Assume there is nothing in our DNS or browser caches when you power on your PC. (Hint: the steps include the use of Ethernet, DHCP, ARP, DNS, TCP, and HTTP protocols.) Explicitly indicate in your steps how you obtain the IP and MAC addresses of a gateway router. RATIONALE back to top SUBJECT LEARNING OUTCOMES This assessment task will assess the following learning outcome/s: · 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. · be able to ascertain and evaluate selection of applications and protocols for transferring data across the internet. GRADUATE LEARNING OUTCOMES This task also contributes to the assessment of the followingCSU Graduate Learning Outcome/s: · Information and Research Literacies (Skill) - CSU Graduates demonstrate the skills required to locate, access and critically evaluate existing information and data. · Professional Practice (Knowledge) - CSU Graduates possess the knowledge and understanding of the discipline and the nature of professionalism required for the given profession or discipline in contemporary societies. PRESENTATION back to top The assessment must be submitted electronically with a Cover Page that includes the following information: · Assessment No · Assessment Title · Student Name & ID · Subject Name and Code · Student Email Address · Students must ensure that all tasks/questions are identified clearly with headings. · Answers to the questions must be in your own words and should be precise but complete and informative. No marks will be awarded for any answer containing more than 10% direct quotes (referenced or unreferenced). · APA reference style must be used throughout the document with the bibliography at the end of the document. In-text citations should also follow APA style. APA referencing guide can be accessed via the following link. This also forms a part of the marking rubric.http://student.csu.edu.au/study/referencing-at-csu Please note:Assessment MUST be submitted as ONE MS Word file via Turnitin. Please do not submit *.zip or *.rar or multiple files. Assessments are marked and feedback is attached using a MS Word based tool. Reports that are submitted in PDF format will be re-formatted to Word format in order to be marked. Allowances willnotbe made for any loss of information, diagrams or images as a result of the re-formatting.
