Question 630
At a distributed Cisco ISE deployment, a security review finds: A helpdesk engineer resets client certificates whenever posture failures occur, even when the Posture Work Center reports an unreachable remediation repository. Which recurring operational control would reduce this risk?
Explanation
Correct Answer
Use stage-specific posture error classification instead of broad credential resets. This control addresses recurrence of the observed failure. The governing behavior is: Posture remediation resources can fail independently of EAP certificate authentication and ISE policy evaluation. The ongoing acceptance check remains: The endpoint downloads the missing approved remediation resource, passes posture, and reauthorizes without replacing valid certificates.
Incorrect Answers
Use stage-specific posture error classification instead of broad credential resets. The offered choice instead concerns a different principle: Review posture refresh timings against endpoint update and security response objectives. Those technical conditions are not interchangeable.
Use stage-specific posture error classification instead of broad credential resets. The offered choice instead concerns a different principle: Retain condition-level posture evidence with high-impact access-denial tickets. Those technical conditions are not interchangeable.
The offered option specifies “Verify least-privilege access in every posture state before production rollout”. The question requires “Use stage-specific posture error classification instead of broad credential resets”: Use stage-specific posture error classification instead of broad credential resets. These are not equivalent responses to the stated requirement.
