Question 170
At Briarwood Property Group, a team reports that it corrected the following problem affecting tenant applications and facility services: An internal finance app trusts devices solely because their network address is inside the corporate subnet. Which observation BEST verifies that the correction actually worked?
Explanation
Correct Answer
A compromised internal subnet host cannot reach finance data without valid identity and posture. This is the decisive evidence for the original problem: An internal finance app trusts devices solely because their network address is inside the corporate subnet. It verifies that the intended corrective control—Require identity and device-state verification at each access decision with least privilege—works in the relevant environment; a completed change ticket alone would not prove the outcome at Briarwood Property Group.
Incorrect Answers
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 Briarwood Property Group was resolved. The specific required evidence is: A compromised internal subnet host cannot reach finance data without valid identity and posture.
A simulated account-risk change causes policy enforcement before the next sensitive transaction. This would be relevant evidence for a different failure: A legacy authentication design grants permanent trust to sessions after one password check, usually addressed by Define a continuously evaluated policy engine with per-request access controls and context signals. It does not demonstrate that the current problem at Briarwood Property Group was resolved. The specific required evidence is: A compromised internal subnet host cannot reach finance data without valid identity and posture.
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 Briarwood Property Group was resolved. The specific required evidence is: A compromised internal subnet host cannot reach finance data without valid identity and posture.
