Question 350
An administrator performs a Defender XDR isolate-device action without verifying that the target is a critical medical workstation. What is the BEST corrective Microsoft 365 action for this tenant?
Explanation
Correct Answer
The deciding issue is automated response actions can interrupt essential services when applied without impact analysis. The action 'Use supported incident response actions with asset criticality and business-operations approval.' targets that issue rather than a neighboring Microsoft 365 workload. Confirm it by checking: An isolated test endpoint stops unauthorized traffic while approved emergency access remains available.
Incorrect Answers
Periodic analytical reports and real-time detection pipelines are different operational services. That concern does not account for the stated failure: Automated response actions can interrupt essential services when applied without impact analysis. The relevant design change is: Use supported incident response actions with asset criticality and business-operations approval.
A bare IP address is insufficient to infer the infrastructure's threat relevance or intent. The problem described here is that automated response actions can interrupt essential services when applied without impact analysis.
An increase in detections can represent improved visibility or attack volume rather than failed protection. The problem described here is that automated response actions can interrupt essential services when applied without impact analysis.
