Ongoing availability of data is the most important consideration when selecting key risk indicators (KRIs) to monitor risk trends over time, as it ensures that the KRIs can provide timely and reliable information on the current and future risk status and performance. KRIs are metrics that measure the level of risk exposure and the effectiveness of risk response strategies, and they should be aligned with the enterprise's risk appetite and objectives. Ongoing availability of data means that the data sources and collection methods for the KRIs are consistent, accessible, and sustainable, and that the data quality and integrity are maintained and verified.
Ability to aggregate data, ability to predict trends, and availability of automated reporting systems are not the most important considerations, as they do not affect the validity and usefulness of the KRIs, but rather the presentation and analysis of the KRI data.

A risk response action plan is a document that outlines the specific tasks, resources, timelines, and deliverables for the risk responses, which are the actions or strategies that are taken to address the risks that may affect the organization's objectives, performance, or value creation12.
The most useful tool when measuring the progress of a risk response action plan is an up-to-date risk register, which is a document that records and tracks the significant risks that the organization faces, and the responses and actions that are taken to address them34.
An up-to-date risk register is the most useful tool because it provides a comprehensive and consistent view of the risk landscape, and the status and performance of the risk responses and actions34.
An up-to-date risk register is also the most useful tool because it enables the monitoring and evaluation of the risk response action plan, and the identification and communication of any issues or gaps that need to be resolved or improved34.
The other options are not the most useful tools, but rather possible metrics or indicators that may be used to measure the progress of a risk response action plan. For example:
Percentage of mitigated risk scenarios is a metric that measures the proportion of risk scenarios that have been reduced or eliminated by the risk responses and actions56. However, this metric is not the most useful tool because it does not provide a comprehensive and consistent view of the risk landscape, and it may not capture the residual or emerging risks that may arise after the risk responses and actions56.
Annual loss expectancy (ALE) changes is a metric that measures the difference between the expected annual losses before and after the risk responses and actions78. However, this metric is not the most useful tool because it does not provide a comprehensive and consistent view of the risk landscape, and it may not reflect the qualitative or intangible impacts of the risks or the risk responses and actions78.
Resource expenditure against budget is a metric that measures the amount of resources and funds that have been spent or allocated for the risk responses and actions, compared to the planned or estimated budget .
However, this metric is not the most useful tool because it does not provide acomprehensive and consistent view of the risk landscape, and it may not indicate the effectiveness or efficiency of the risk responses and actions . References =

The internal auditor is the best suited to provide objective input when updating residual risk to reflect the results of control effectiveness. The internal auditor is an independent and impartial function that evaluates the adequacy and effectiveness of the internal controls and reports on the findings and recommendations. The internal auditor can provide an unbiased and reliable assessment of the residual risk, which is the risk that remains after the controls are applied. The other options are not as objective as the internal auditor, as they may have vested interests or conflicts of interest in the control environment.

Preparing a risk response that is aligned to the organization's risk tolerance is the next step after completing a risk assessment and reporting the validated vulnerability findings that require mitigation to the application owner, because it helps to define and implement the appropriate actions to reduce or eliminate the risk, or to prepare for and recover from the potential consequences. A risk response is a strategy or tactic for managing the identified risks, such as avoiding, transferring, mitigating, or accepting the risk. A risk response should be aligned to the organization's risk tolerance, which is the acceptable level of variation from the organization's objectives or expectations. A vulnerability is a weakness or flaw in an IT system or application that can be exploited by a threat or attack to cause harm or damage. A vulnerability finding is a result of a vulnerability assessment, which is a process of identifying and evaluating the vulnerabilities in an IT system or application.
A vulnerability finding requires mitigation, which is a type of risk response that involves applying controls or countermeasures to reduce the likelihood or impact of the risk. Therefore, preparing a risk response that is aligned to the organization's risk tolerance is the next step, as it helps to address the vulnerability findings and to achieve the desired level of risk. Reporting the findings to executive management, reassessing each vulnerability, and conducting a penetration test are all possible steps to perform after preparing a risk response, but they are not the next step, as they depend on the results and approval of the risk response.

The most important consideration when establishing a contingency plan and an alternate processing site for a company that has located its computer center on a moderate earthquake fault is that the alternative site does not reside on the same fault no matter how far the distance apart, as it ensures that the alternative site is not affected by the same earthquake event that may disrupt the primary site, and that the business continuity and recovery objectives can be met. The other options are not the most important considerations, as they are more related to the backup, priority, or readiness of the alternative site, respectively, rather than the location of the alternative site.
