The key performance indicator (KPI) that best measures the effectiveness of an organization's disaster recovery program is the percentage of critical systems recovered within the recovery time objective (RTO).
The RTO is the acceptable timeframe within which a business process or system must be restored after a disruption. The percentage of critical systems recovered within the RTO indicates how well the disaster recovery program can meet the business continuity requirements and minimize the impact of the disruption.
The other options are not as good as the percentage of critical systems recovered within the RTO, as they are related to the efficiency, quality, or scope of the disaster recovery program, not the effectiveness of the disaster recovery program.

The best metric to demonstrate that servers are configured securely is the total number of servers meeting the baseline for hardening. Hardening is the process of applying security configurations and settings to servers to reduce their attack surface and vulnerability. A baseline is a standard or benchmark that defines the minimum level of security required for servers. By measuring the number of servers that meet the baseline, the organization can assess the effectiveness of its hardening efforts and identify any gaps or deviations. The other metrics, such as exceeding availability thresholds, experiencing hardware failures, or exceeding current patching standards, are not directly related to the security configuration of servers, but rather to their performance, reliability, or maintenance.

The most relevant information to include in a risk management strategy is the organizational goals, because they provide the direction and purpose for the risk management activities. A risk management strategy is a document that outlines the objectives, scope, approach, roles, and responsibilities for managing risks in an organization. A risk management strategy should align with the organizational goals, which are the desired outcomes or results that the organization wants to achieve. The organizational goals should be specific, measurable, achievable, relevant, and time-bound (SMART), and they should reflect the organization's vision, mission, values, and strategy. By including the organizational goals in the risk management strategy, the risk practitioner can ensure that the risk management process supports and enables the achievement of the organizational goals. The risk practitioner can also use the organizational goals as a basis for identifying, assessing, prioritizing, and responding to the risks that may affect the organization's performance and success.
The risk practitioner can also monitor and measure the progress and effectiveness of the risk management process by comparing the actual results with the expected results based on the organizational goals. Therefore, the organizational goals are the most relevant information to include in a risk management strategy, as they provide the foundation and framework for the risk management process.

The best course of action when a recent regulatory requirement has the potential to affect an organization's use of a third party to supply outsourced business services is to conduct a gap analysis, as it involves comparing the current and desired states of compliance, and identifying any gaps or discrepancies that need to be addressed. Terminating the outsourcing agreement, identifying compensating controls, and transferring risk to the third party are not the best courses of action, as they may not be feasible, effective, or appropriate, respectively, and may require the prior knowledge of the compliance gaps and risks.

According to the CRISC Review Manual, risk appetite is the amount and type of risk that an organization is willing to accept in pursuit of its objectives. Risk appetite is a key factor in communicating the risk associated with IT in business terms, because it helps to align the IT risk management with the business strategy and goals. Risk appetite also helps to define the risk tolerance and thresholds, which are the acceptable levels of variation around the objectives. The other options are not the correct answers, because they are not essential for communicating the risk associated with IT in business terms. Compliance objectives are the objectives that an organization must achieve to comply with the applicable laws, regulations, standards, and contracts.
Organizational objectives are the objectives that an organization sets to achieve its mission, vision, and values. Inherent and residual risk are the risk levels before and after applying the risk responses, respectively. References = CRISC Review Manual, 7th Edition, Chapter 2, Section 2.1.1, page 66.
