1. A station running TCP/IP needs to transfer a file to a host. The file contains 1024 bytes. How many bytes, including all of the TCP/IP overhead, would be sent, assuming a payload size of 128 bytes and both systems are running IPv4? (Also assume that the three-way handshake and window size negotiation have been completed and that no errors occur during transmission.) i) what is the protocol overhead (stated as a percentage)? [3 marks] ii) perform the same calculation, this time assuming that both clients are using IPv6. [2 marks] 2. IP is a connection-less protocol, whereas TCP is connection-oriented. How can these two protocols coexist in the same protocol stack? [4 marks] 3. Mention one advantage and one disadvantage of Agile method. [4 marks] 4. Compare and contrast the Agile method and Evolutionary software development process. Explain with an example. [4 marks] 5. Analyse the uniqueness of Apple design process. [4 marks] 6. Describe three reasons for a project failure. [5 marks] 7. Your company owns several software and asked you to manage them within company budget constraints. What will be your goals? [4 marks] Rationale back to top This assessment task will assess the following learning outcome/s: be able to discuss the features of various software development methodologies. be able to discuss and analyse fundamental networking concepts, protocols and standards. be able to discuss the principle lifecycle phases of an information system, from requirements and acquisition through to operation and maintenance. be able to compare and contrast the role of IT service management frameworks, policies and compliance issues. Marking criteria and standards back to top Criteria HD (85%-100%) DI (75%-84%) CR (65%-74%) PS (50%-64%) FL (0%-49%) Comprehension of network protocols and standards Answers are corrects. All steps are correctly shown. All calculations are accurately performed. All answers are correct with a minor error. All calculations are correct except a minor error. Few minor errors in calculating the overhead. The steps show the clear understanding of the overhead calculation. The final result is not correct, however the calculations show the basic understanding of the protocol overhead. No attempt or incorrect calculations showing no or minimum understanding of the topic. Ability to discuss the features of various software development methodologies, the principle life-cycle phases of an information system, compare and contrast the role of IT service management frameworks, policies and compliance issues. Demonstrated comprehensive knowledge to consistently recall accurate facts and apply the relevant ones correctly in context. Analysed and accurately interpreted communication data and information in detail. Succinctly explained and justified all statements, providing a clear and accurate logical solution. Demonstrated knowledge to recall mostly accurate facts and apply the majority of the relevant ones correctly in context. Analysed and accurately interpreted the communication data and information in detail. Explained and justified all statements. Providing (for the most part) a clear and logical solution. Demonstrated knowledge to recall some accurate facts and apply some of the relevant ones correctly in context. Analysed and accurately (for some parts) interpreted the communication data and information. Explained and justified most of the statements by relating to aspects of the given context. Demonstrated partially-developed knowledge to recall a few accurate facts and apply some of them correctly in contexts. Analysed and (for a few part) interpreted the communication data and information. Explained and justified at least half of the statements but in many cased used irrelevant or incorrect facts. Listed some facts and little reasons. Stated some identifications and implications by giving simple observation and or reason that may or may not relate to the given context.
