Question 90
During a security analytics acceptance test, operators report: A malicious domain appears in both DNS and web-filter records, but the analyst incorrectly counts every record as a distinct infected host. What evidence would best demonstrate that the intended workflow now works?
Explanation
Correct Answer
This directly verifies indicators across dns and web traffic: Affected host counts reflect unique verified endpoints rather than the number of individual log messages. The linked remediation is: Group events by endpoint identity, domain and time and retain both detection types as supporting observations. A result from an unrelated SOC function does not prove this requirement.
Incorrect Answers
The evidence inventory distinguishes hash and event record from any separately acquired file sample. This is a different failure mechanism from the current case, which concerns affected host counts reflect unique verified endpoints rather than the number of individual log messages.
This option instead describes the final event list includes pre- and post-midnight records from the same investigative interval. Testing that independent mechanism would not show whether the reported fault has been resolved.
The report distinguishes elapsed session lifetime from measured application response time. The stem describes a malicious domain appears in both DNS and web-filter records, but the analyst incorrectly counts every record as a distinct infected host, so this explanation does not account for the observations.
