Question 820
Which operational change is most appropriate after the team observes: A quarantine policy references a network tag generated for all outdated operating systems but one pilot device is unexpectedly excluded.
Explanation
Correct Answer
The selected action isolates the problem described rather than changing unrelated controls. Validate tag criteria and endpoint group inclusion across representative impacted platforms. Underlying reason: Dynamic quarantine membership reflects policy conditions and the endpoints actually evaluated by EMS. Confirm resolution by observing: Devices meeting the condition receive the expected restrictive tag across targeted groups.
Incorrect Answers
That option would be better suited to the separate incident 'Help desk staff are unable to patch a compromised endpoint because every network destination is denied.' Its supporting principle is quarantine can require narrow management or recovery exceptions without granting general network access. In this case the key condition is dynamic quarantine membership reflects policy conditions and the endpoints actually evaluated by EMS.
Although this option is relevant to 'A security profile is designed to quarantine devices after a single misleading test event without any validation.', it would not distinguish the actual incident described. The target is to validate tag criteria and endpoint group inclusion across representative impacted platforms. and establish devices meeting the condition receive the expected restrictive tag across targeted groups.
The distractor addresses a related but distinct failure: 'A vulnerability scan tag moves a device to a restrictive group after a policy threshold is exceeded.' The current technical boundary is dynamic quarantine membership reflects policy conditions and the endpoints actually evaluated by EMS. and the required evidence is Devices meeting the condition receive the expected restrictive tag across targeted groups.
