Question 620
A support engineer proposes closing this case: A roaming laptop is isolated in one subnet but reaches the same sensitive application from another. Which result should be recorded first?
Explanation
Correct Answer
This observation addresses the actual reported defect: The affected endpoint stays restricted when its address or access network changes. It would validate the action use supported dynamic endpoint identity or posture tagging to apply consistent isolation across access paths. The underlying condition is that device-based security posture is more robust than a one-time address-only block for mobile endpoints.
Incorrect Answers
The proposed proof can be useful for 'A noncompliant laptop receives a quarantine policy because its antivirus module is disabled.' But that is not the present device state; an appropriate response to the current scenario is use supported dynamic endpoint identity or posture tagging to apply consistent isolation across access paths.
This does not directly test the stated failure. It addresses 'A compromised device is released after a verbal instruction without a reviewable audit trail.' where accountable incident containment needs traceable decisions as well as technical enforcement. Here the necessary verification is: The affected endpoint stays restricted when its address or access network changes.
The alternate choice relates to 'Help desk staff are unable to patch a compromised endpoint because every network destination is denied.' It would prompt design limited authorized remediation connectivity for isolated endpoints under an explicit security policy. The current issue instead requires use supported dynamic endpoint identity or posture tagging to apply consistent isolation across access paths.
