- An external IS auditor discovers that systems in the scope of the audit were implemented by an associate. In such a circumstance, IS audit management should:A.remove the IS auditor from the engagement.B.cancel the engagement.C.disclose the issue to the client.D.take steps to restore the IS auditor's independence.
- The PRIMARY purpose of an IT forensic audit is:A.to participate in investigations related to corporate fraud.B.the systematic collection and analysis of evidence after a system irregularity.C.to assess the correctness of an organization's financial statements.D.to preserve evidence of criminal activity.
- An IS auditor discovers that devices connected to the network are not included in a network diagram that had been used to develop the scope of the audit. The chief information officer explains that the diagram is being updated and awaiting final approval. The IS auditor should FIRST:A.expand the scope of the IS audit to include the devices that are not on the network diagram.B.evaluate the impact of the undocumented devices on the audit scope.C.note a control deficiency because the network diagram has not been approved.D.plan follow-up audits of the undocumented devices.
- When evaluating the controls of an electronic data interchange (EDI) application, an IS auditor should PRIMARILY be concerned with the risk of:A.excessive transaction turnaround time.B.application interface failure.C.improper transaction authorization.D.nonvalidated batch totals.
- The PRIMARY objective of the audit initiation meeting with an IS audit client is to:A.discuss the scope of the audit.B.identify resource requirements of the audit.C.select the methodology of the audit.D.collect audit evidence.
- If the optimal solution to the LP relaxation problem is integer, it is the optimal solution to the integer linear program.
- Let x1 and x2 be 0-1 variables whose values indicate whether projects 1 and 2 are not done or are done.Which answer below indicates that project 1 can be done only if project 2 is done?
- Slack and surplus variables are not useful in integer linear programs thus should be disregarded.
- Assuming W1, W2 and W3 are 0 -1 integer variables, the constraint W1 + W2 + W3 <= 2 is often called a
- The smallest possible value of regret is:
- Let x1 , x2 , x3, and x4 be 0-1 variables whose values indicate whether the projects are not done or are done. Which answer below indicates that no more than 3 projects can be done?
- For a minimization problem (such as cost), the optimistic approach is often referred to as the
- Decision alternatives are structured so that several could occur simultaneously.
- States of nature should be defined so that one and only one will actually occur.
- The expected value of an alternative is always positive.
- Regret is the difference between the payoff associated with a particular decision alternative and the payoff associated with the decision that would yield the most desirable payoff for a given state of nature.
- For a maximization problem (such as profit, return, or sales revenue), the optimistic approach is often referred to as the
- For questions with payoff measured in profit, EVwPI is always greater than the EVwoPI.
- The options from which a decision maker chooses a course of action are
- In a model, x1 ≥ 0, x2 ≥ 0 and integer, and x3 = 0, 1. Which solution would be feasible?
