Q

QUESTION 1 - (Topic 1)
Structured programming is BEST described as a technique that:
A. provides knowledge of program functions to other programmers via peer reviews.
B. reduces the maintenance time of programs by the use of small-scale program modules.
C. makes the readable coding reflect as closely as possible the dynamic execution of the program.
D. controls the coding and testing of the high-level functions of the program in the development process.

A

Answer: B
Explanation:
A characteristic of structured programming is smaller, workable units. Structured programming has evolved because
smaller, workable units are easier to maintain. Structured programming is a style of programming which restricts the
kinds of control structures. This limitation is not crippling. Any program can be written with allowed control structures.
Structured programming is sometimes referred to as go-to-less programming, since a go-to statement is not allowed. This
is perhaps the most well known restriction of the style, since go-to statements were common at the time structured
programming was becoming more popular. Statement labels also become unnecessary, except in languages where
subroutines are identified by labels.

IS auditors are MOST likely to perform compliance tests of internal controls if, after their initial evaluation of the
controls, they conclude that control risks are within the acceptable limits. True or false?
A. True
B. False

A

Answer: A
Explanation: IS auditors are most likely to perform compliance tests of internal controls if, after their initial evaluation of the controls, they conclude that control risks are within the acceptable limits. Think of it this way: If any reliance is placed on internal controls, that reliance must be validated through compliance testing. High control risk results in little reliance on internal controls, which results in additional substantive testing.

QUESTION 39 - (Topic 1)
Which of the following tests is an IS auditor performing when a sample of programs is selected to determine if the source and object versions are the same?
A. A substantive test of program library controls
B. A compliance test of program library controls
C. A compliance test of the program compiler controls
D. A substantive test of the program compiler controls

A

Answer: B
Explanation:
A compliance test determines if controls are operating as designed and are being applied in a manner that complies with
management policies and procedures. For example, if the IS auditor is concerned whether program library controls are
working properly, the IS auditor might select a sample of programs to determine if the source and object versions are the
same. In other words, the broad objective of any compliance test is to provide auditors with reasonable assurance that a
particular control on which the auditor plans to rely is operating as the auditor perceived it in the preliminary evaluation.

QUESTION 41 - (Topic 1)
Which of the following is MOST likely to result from a business process reengineering (BPR) project?
A. An increased number of people using technology
B. Significant cost savings, through a reduction in the complexity of information technology
C. A weaker organizational structures and less accountability
D. Increased information protection (IP) risk will increase

A

Answer: A
Explanation:
A BPR project more often leads to an increased number of people using technology, and this would be a cause for
concern. Incorrect answers:
B. As BPR is often technology oriented, and this technology is usually more complex and volatile than in the past, cost
savings do not often materialize in this area.
D. There is no reason for IP to conflict with a BPR project, unless the project is not run properly.

QUESTION 50 - (Topic 1)
A call-back system requires that a user with an id and password call a remote server through a dial-up line, then the server disconnects and:
A. dials back to the user machine based on the user id and password using a telephone number from its database.
B. dials back to the user machine based on the user id and password using a telephone number provided by the user
during this connection.
C. waits for a redial back from the user machine for reconfirmation and then verifies the user id and password using its database.
D. waits for a redial back from the user machine for reconfirmation and then verifies the user id and password using the
sender’s database.

A

Answer: A
Explanation:
A call-back system in a net centric environment would mean that a user with an id and password calls a remote server through a dial-up line first, and then the server disconnects and dials back to the user machine based on the user id and password using a telephone number from its database. Although the server can depend upon its own database, it cannot know the authenticity of the dialer when the user dials again. The server cannot depend upon the sender’s database to dial back as the same could be manipulated.
