Question 190
At Oceanview Payments, a team reports that it corrected the following problem affecting regulated payments and credentialed access: A legacy authentication design grants permanent trust to sessions after one password check. Which observation BEST verifies that the correction actually worked?
Explanation
Correct Answer
A simulated account-risk change causes policy enforcement before the next sensitive transaction. This is the decisive evidence for the original problem: A legacy authentication design grants permanent trust to sessions after one password check. It verifies that the intended corrective control—Define a continuously evaluated policy engine with per-request access controls and context signals—works in the relevant environment; a completed change ticket alone would not prove the outcome at Oceanview Payments.
Incorrect Answers
Ordinary employees cannot call administrative endpoints; approved time-bound elevation works. This would be relevant evidence for a different failure: A cloud service gives every employee broad administrative API permissions after single sign-on, usually addressed by Apply role-based least privilege and just-in-time privileged elevation with auditable conditions. It does not demonstrate that the current problem at Oceanview Payments was resolved. The specific required evidence is: A simulated account-risk change causes policy enforcement before the next sensitive transaction.
A contractor reaches only assigned applications and unrelated services remain inaccessible. This would be relevant evidence for a different failure: Remote contractors can access every internal service after a single perimeter VPN login, usually addressed by Adopt application-specific zero-trust access based on user, device, and resource policy. It does not demonstrate that the current problem at Oceanview Payments was resolved. The specific required evidence is: A simulated account-risk change causes policy enforcement before the next sensitive transaction.
A service reaches only its approved dependency regardless of its assigned subnet. This would be relevant evidence for a different failure: Network segmentation is based only on data-center VLAN placement, leaving workload identities unverified, usually addressed by Apply identity-aware microsegmentation and explicit workload-to-workload policies. It does not demonstrate that the current problem at Oceanview Payments was resolved. The specific required evidence is: A simulated account-risk change causes policy enforcement before the next sensitive transaction.
