Q2

My answer: C Correct answer: A An email address by its self won’t cause much harm, however, an email password would. The answer is A because cookies stored in the user’s Web browser can contain saved passwords, creditcard info, and more, all accessable without a password.

Q4

My answer: D Correct answer: A The correct answer here is D, as having the data in a database will only need to more data stored, increacing the need for data compression. However, having all the data in a singular database allows for easy analysis of the data within calling sessions, and make updates and decisions based on the data.

Q7

My answer: C Correct answer: A Of the three answer choices, only I was not needed by the original system, as there was no need for the customer to verbally disclose what they wanted to pick, all they needed was to select a number on a keypad. However, a call into the system is still nesscary, therefore choice III was needed.

Q29

My answer: D Correct answer: B The correct answer here was B, because in step 4, a is being assigned the value of NOT (a OR b) AND c. a was assigned with true in step one, b assigned with false and c assigned with true. Therefore, NOT (a OR b) is the opposite of a or b, which is the opposite of true, being false. false AND c is false, therefore a is assigned with false. Taking this value of a equaling false and doing c AND a results in false AND false, which is false. Therefore, the correct answer is B.

Q49

My answer: D Correct answer: B Simulations will lack important details. Wether it is because of the programers forgeting a detail or an unexpected detail pops up, simulations will not be able to account for every detail, and may omit details to make it easier to implement.
