Question 460
An EDR policy should isolate a compromised endpoint but the help desk confuses quarantine with full device wipe. Which result would demonstrate that the new configuration works?
Explanation
Correct Answer
This is the acceptance evidence for this specific situation: The infected pilot loses unauthorized network access while forensic evidence is preserved. It would confirm that the intended intervention, 'Use appropriate Defender incident-response containment and coordinate with Intune management actions.', addressed the problem because threat containment and destructive enrollment cleanup have different purposes.
Incorrect Answers
This observation would validate a different case: A finance laptop has BitLocker active but the end user sees a recovery prompt after a firmware change. It would check 'The device restarts normally with its protected drive after authorized recovery.' after 'Validate platform security/TPM state and recover using approved key escrow before altering encryption policy.'. It does not establish success for the stated scenario; the needed evidence is 'The infected pilot loses unauthorized network access while forensic evidence is preserved.'.
This observation would validate a different case: An ASR rule blocks a business-approved legacy app, and the service desk suggests turning off all ASR protections. It would check 'The approved app runs while unrelated ASR detections remain enforced.' after 'Create a tightly scoped policy exception or compatible application update after security review.'. It does not establish success for the stated scenario; the needed evidence is 'The infected pilot loses unauthorized network access while forensic evidence is preserved.'.
This observation would validate a different case: A fleet must enforce BitLocker encryption and escrow recovery keys in Microsoft Entra ID for help desk recovery. It would check 'A newly encrypted pilot laptop reports BitLocker enabled and a protected recovery key exists in directory.' after 'Create an Intune disk encryption policy with appropriate escrow and recovery settings.'. It does not establish success for the stated scenario; the needed evidence is 'The infected pilot loses unauthorized network access while forensic evidence is preserved.'.
