Explanation:
Pilot testing and reviewing of performance data to verify operation against design are done before relying on control.
Incorrect Answers:
B: Discovering risk exposure helps in identifying the severity of risk, but it does not play any role in specifying the reliability of control.
D: Articulating risk is the first phase in the risk response process to ensure that information on the true state of exposures and opportunities are made available in a timely manner and to the right people for appropriate response. But it does not play any role in identifying whether any specific control is reliable or not.

The primary focus of management when key risk indicators (KRIs) begin to rapidly approach defined thresholds is to determine what has changed in the environment. KRIs are metrics that provide information and insight on the current level and trend of the risk exposure, and help to monitor and report the risk status and performance. Defined thresholds are the values or ranges of the KRIs that indicate the acceptable or unacceptable level of the risk exposure, and trigger the risk response actions. When KRIs begin to rapidly approach defined thresholds, it means that the risk exposure is increasing or decreasing significantly, and that the risk situation and status may have changed. Therefore, the primary focus of management is to determine what has changed in the environment, which is the internal or external context that influences or affects the risk exposure and impact. Determining what has changed in the environment helps to identify and analyze the causes, drivers, or factors of the risk change, and to evaluate the implications and consequences of the risk change. Determining what has changed in the environment also helps to update and adjust the risk assessment and response, and to communicate and escalate the risk change to the relevant stakeholders. Designing compensating controls, determining if KRIs have been updated recently, and assessing the effectiveness of the incident response plan are not the primary focus of management, as they are either the outputs or the inputs of the risk change analysis, and they do not address the primary need of understanding the risk change.

Explanation:
The Business Continuity Strategy is an outline of the approach to ensure the continuity of Vital Business Functions in the case of disaster events. The Business Continuity Strategy is prepared by the business and serves as a starting point for producing the IT Service Continuity Strategy.
Incorrect Answers:
B: Index of Disaster-Relevant Information is a catalog of all information that is relevant in the event of disasters. This document is maintained and circulated by IT Service Continuity Management to all members of IT staff with responsibilities for fighting disasters.
C: Disaster Invocation Guideline is a document produced by IT Service Continuity Management with detailed instructions on when and how to invoke the procedure for fighting a disaster. Most importantly, the guideline defines the first step to be taken by the Service Desk after learning that a disaster has occurred.
D: Availability/ ITSCM/ Security Testing Schedule is a schedule for the regular testing of all availability, continuity, and security mechanisms jointly maintained by Availability, IT Service Continuity, and IT Security Management.
