Question 550
At Oceanview Payments, a team reports that it corrected the following problem affecting regulated payments and credentialed access: A team deploys a managed platform runtime but takes responsibility for host hypervisor maintenance it cannot control. Which observation BEST verifies that the correction actually worked?
Explanation
Correct Answer
A control map reflects correct PaaS ownership and tests the customer's application controls. This is the decisive evidence for the original problem: A team deploys a managed platform runtime but takes responsibility for host hypervisor maintenance it cannot control. It verifies that the intended corrective control—Distinguish provider-controlled PaaS infrastructure from customer-managed code, identity, data, and configuration—works in the relevant environment; a completed change ticket alone would not prove the outcome at Oceanview Payments.
Incorrect Answers
An ownership review identifies each control and a backup recovery rehearsal meets the documented objective. This would be relevant evidence for a different failure: An organization has multiple public cloud accounts but cannot determine who owns backup recovery for each workload, usually addressed by Define workload-specific customer and provider responsibility for resilience, encryption, and recovery. It does not demonstrate that the current problem at Oceanview Payments was resolved. The specific required evidence is: A control map reflects correct PaaS ownership and tests the customer's application controls.
An audit traces required safeguards to named customer and service-provider evidence owners. This would be relevant evidence for a different failure: A migration project claims purchasing cloud service automatically transfers regulatory accountability to the vendor, usually addressed by Document customer accountability for data classification, lawful processing, and chosen configurations. It does not demonstrate that the current problem at Oceanview Payments was resolved. The specific required evidence is: A control map reflects correct PaaS ownership and tests the customer's application controls.
An unauthorized principal cannot read the data even though the underlying storage service is managed. This would be relevant evidence for a different failure: A cloud administrator believes the provider's physical security eliminates the need to restrict object-storage policies, usually addressed by Enforce customer-owned access controls, encryption choices, and bucket exposure policies. It does not demonstrate that the current problem at Oceanview Payments was resolved. The specific required evidence is: A control map reflects correct PaaS ownership and tests the customer's application controls.
