Question 830
At Willowbrook Education, a team reports that it corrected the following problem affecting student collaboration platforms: A security analyst dismisses a risky domain because one benign shared IP address appears in the results. Which observation BEST verifies that the correction actually worked?
Explanation
Correct Answer
Related indicators are evaluated and a high-confidence threat receives an appropriate response. This is the decisive evidence for the original problem: A security analyst dismisses a risky domain because one benign shared IP address appears in the results. It verifies that the intended corrective control—Interpret domain indicators and infrastructure relationships without treating shared hosting alone as proof of safety—works in the relevant environment; a completed change ticket alone would not prove the outcome at Willowbrook Education.
Incorrect Answers
Verified malicious domains are blocked with documented evidence while expired indicators are retired. This would be relevant evidence for a different failure: Investigate shows multiple domain indicators but the SOC has no process to share validated findings with DNS security teams, usually addressed by Record confidence, relevant indicators, and expiry and promote approved intelligence into enforcement feeds. It does not demonstrate that the current problem at Willowbrook Education was resolved. The specific required evidence is: Related indicators are evaluated and a high-confidence threat receives an appropriate response.
The case lists the relevant risk category and supporting observations rather than a bare score. This would be relevant evidence for a different failure: A suspicious domain is blocked by policy but investigators cannot explain whether its risk reflects malware, phishing, or infrastructure reputation, usually addressed by Analyze available Investigate classifications and correlate with independent telemetry. It does not demonstrate that the current problem at Willowbrook Education was resolved. The specific required evidence is: Related indicators are evaluated and a high-confidence threat receives an appropriate response.
The current score and its source time are recorded with the final policy choice. This would be relevant evidence for a different failure: A threat investigation uses an old cached domain score after a verified change in reputation, usually addressed by Refresh investigation data and compare timestamps before making the final enforcement decision. It does not demonstrate that the current problem at Willowbrook Education was resolved. The specific required evidence is: Related indicators are evaluated and a high-confidence threat receives an appropriate response.
