Question 220
An organization sees repeated unexpected restarts on one hardware model after a new driver rollout. How should the administrator establish that the intended control succeeded?
Explanation
Correct Answer
This is the acceptance evidence for this specific situation: The post-remediation model reports fewer unexpected restarts under comparable usage. It would confirm that the intended intervention, 'Correlate restart frequency with device model and driver deployment history.', addressed the problem because reliability changes should be investigated by cohort and change timing.
Incorrect Answers
This observation would validate a different case: An endpoint admin wants an operational baseline for acceptable device startup time before an OS upgrade. It would check 'The post-upgrade cohort can be assessed against the saved pre-upgrade distribution.' after 'Measure representative Endpoint Analytics startup metrics and record target thresholds in advance.'. It does not establish success for the stated scenario; the needed evidence is 'The post-remediation model reports fewer unexpected restarts under comparable usage.'.
This observation would validate a different case: A service desk needs to identify whether Windows endpoints have slow startup caused by a new login agent rather than simple user complaints. It would check 'The agent-installed cohort shows its startup score compared with the previous baseline.' after 'Review Endpoint Analytics startup performance reports and compare deployment cohorts.'. It does not establish success for the stated scenario; the needed evidence is 'The post-remediation model reports fewer unexpected restarts under comparable usage.'.
This observation would validate a different case: Endpoint Analytics reports poor application reliability but the team monitors only Windows boot speed. It would check 'A targeted report identifies the affected app crash trend separately from boot duration.' after 'Use application reliability metrics alongside startup performance in Endpoint Analytics.'. It does not establish success for the stated scenario; the needed evidence is 'The post-remediation model reports fewer unexpected restarts under comparable usage.'.
