Question 6

One of the firm's beginner analysts is working on a financial process that will continue to print vendor payments until it reaches the end of the file. Which of the following processes will Evan suggest that the analyst use?
A) sequence
B) selection
C) concatenation
D) iteration

Accepted Answer

Iteration involves repeating a process until a certain condition is met, such as reaching the end of a file. This would be the most appropriate process for the analyst to use in order to print vendor payments until the end of the file is reached.

Question 8

Another of the firm's analysts has been pounding his head against his desk for 10 minutes because he cannot figure out what is wrong with some structured English he has been using to describe the processing logic. Evan walks over and spots the problem in an instant. Which of the following can be what Evan identifies as the problem?
A) The structured English is indented.
B) The structured English is not using a sequence, selection, or iteration structure.
C) The structured English uses a limited vocabulary.
D) All of the above.

Accepted Answer

The fact that the structured English is not using a sequence, selection, or iteration structure indicates that there is a problem with the processing logic. The other options may cause issues with readability or ease of understanding but they would not affect the logic itself.

Question 9

Which of the following will NOT be developed if they decide to use the four-model approach?
A) A physical model of the current system.
B) A logical model of the current system.
C) A teleological model of the current system.
D) All of the above.

Accepted Answer

The four-model approach includes developing a physical model, a logical model, a teleological model, and a mathematical model of the current system. Therefore, if they decide to use the four-model approach, all of the models mentioned in options A and B will be developed. Option C, a teleological model, is not typically included in the four-model approach, so it will not be developed.
