This quiz mainly tests assumptions and principles about cryptography. You should answer questions within the context of the assumptions made and notation used during lecture (which are summarised in this PDF). Be careful with multiple choice questions that allow selecting one or more answers: usually you must select all possible correct answers to get full marks and selecting one incorrect answer will result in 0 marks.
Questions: a | b | c | d. Answers. See your Grades.
All questions in this quiz are the same structure: a network diagram is presented, and then you need to either design a firewall rule to implement a policy, or select which rule applies to a specific packet. The network diagram is exactly the same in every question. Therefore read the instructions in the first question carefully, and then the subsequent questions should be faster.
