1. Right Answer: C Explanation: A reasonableness check is a data validation edit control that matches input data to an occurrence rate.
2. Right Answer: A Explanation: Database snapshots can provide an excellent audit trail for an IS auditor.
3. Right Answer: A Explanation: Using a statistical sample to inventory the tape library is an example of a substantive test.
4. Right Answer: C Explanation: Compliance testing determines whether controls are being applied in compliance with policy. This includes tests to determine whether new accounts were appropriately authorized. Variable sampling is used to estimate numerical values, such as dollar values. Substantive testing substantiates the integrity of actual processing; such as balances on financial statements. The development of substantive tests is often dependent on the outcome of compliance tests. If compliance tests indicate that there are adequate internal controls, then substantive tests can be minimized. Stop-or-go sampling allows a test to be stopped as early as possible and is not appropriate for checking whether procedures have been followed.
5. Right Answer: B Explanation: Detection risks are directly affected by the auditor's selection of audit procedures and techniques. Inherent risks are not usually affected by an IS auditor. Control risks are controlled by the actions of the company's management. Business risks are not affected by an IS auditor.
