Question 660
During a payment-platform modernization at a payment clearing organization, the IS auditor learns that a disaster recovery runbook assumes unavailable credentials stored at the primary site. The affected operation supports merchant settlement and reconciliation. Finance and settlement integrity depend on this operation. Which evidence would BEST support a conclusion that the exposure has been addressed?
Explanation
Correct Answer
Correct. A timed restore or failover test confirms users can perform critical transactions with approved RTO and RPO outcomes. This is stronger than a manager's verbal assurance because it can be checked against the observed issue that a disaster recovery runbook assumes unavailable credentials stored at the primary site. The reviewer must verify the remediation period and scope.
