A disaster recovery test is a simulation of a disaster scenario that evaluates the effectiveness and readiness of the disaster recovery plan. The main purpose of a disaster recovery test is to ensure that the organization can resume its normal operations as quickly as possible after a disaster, with minimal or no data loss. Therefore, the most important objective of a disaster recovery test from a business perspective is to verify that all critical data can be recovered within the RTOs, which are the maximum acceptable time frames for restoring the data and systems after a disaster. If the RTOs are not met, the organization may face significant financial, operational, and reputationallosses. The other options are not the most important objectives of a disaster recovery test, although they may be beneficial outcomes. Gaining assurance that the organization can recover from a disaster is a subjective and qualitative goal, while recovering data within RTOs is a measurable and quantitative goal. Discovering errors in the disaster recovery process is a valuable result of a disaster recovery test, but it is not the primary objective. The objective is to correct the errors and improve the process, not just to find them. Testing all business criticalsystems is a necessary step in a disaster recovery test, but it is not the ultimate goal. The goal is to ensure that the systems can be restored and function properly within the RTOs. References = CRISC Review Manual, pages 197-1981; CRISC Review Questions, Answers & Explanations Manual, page 572
