To ensurecompleteness of outbound transactions, alog with periodic validationis thebest control.
Option A (Incorrect):Edit checkshelp withdata accuracy, not completeness.
Option B (Incorrect):Sequential numberingdetects missing transactions but does not verifyactual transmission.
Option C (Incorrect):Recipient ID validationis important foraccuracy, not for ensuring all transactions are sent.
Option D (Correct):Maintaining and validating transaction logsensures thatall outbound transactions are properly accounted for, making it the best completeness control.

The greatest benefit of adopting an international IT governance framework rather than establishing a new framework based on the actual situation of a specific organization is wide acceptance by different business and support units with IT governance objectives. An international IT governance framework, such as COBIT, provides a common language and understanding for IT governance among various stakeholders, such as management, users, auditors and regulators. This facilitates alignment, communication and collaboration among them. Readily available resources, comprehensive coverage and fewer resources expended are also benefits of adopting an international IT governance framework, but they are not the greatest benefit.

An organization is shifting to a remote workforce. In preparation, the IT department is performing stress and capacity testing of remote access infrastructure and systems. This type of control is being implemented to direct or guide actions to achieve a desired outcome. Therefore, it is a directive control. Directive controls are proactive controls that seek to prevent undesirable events from occurring. They include policies, standards, procedures, guidelines, training, and testing. Detective controls are reactive controls that seek to identify undesirable events that have already occurred. They include monitoring, logging, auditing, and reporting.
Preventive controls are proactive controls that seek to avoid undesirable events from occurring. They include authentication, encryption, firewalls, and antivirus software. Compensating controls are alternative controls that provide a similar level of protection as the primary controls when the primary controls are not feasible or cost-effective. They include segregation of duties, manual reviews, and backup systems. References: CISA Review Manual (Digital Version), [ISACA Glossary of Terms]

The IS auditor's best course of action in this situation is to determine whether the alternative controls sufficiently mitigate the risk. Alternative controls are different from those originally discussed and agreed with the audit function, but they may still achieve the same objective of addressing the audit issue or reducing the risk to an acceptable level. The IS auditor should evaluate whether the alternative controls are appropriate, effective, and sustainable before closing the audit finding or escalating it to senior management. The other options are not appropriate for resolving this situation, as they do not consider whether the alternative controls are adequate or reasonable. Re-prioritizing the original issue as high risk and escalating to senior management is a drastic step that may undermine the relationship between the auditor and management, and it should be done only after exhausting other means of resolving the issue. Scheduling a follow-up audit in the next audit cycle is unnecessary, as follow-up activities should be performed as soon as possible after management has implemented corrective actions. Postponing follow-up activities and escalating the alternative controls to senior audit management is premature, as follow-up activities should be completed before reporting any findings or recommendations to senior audit management.
