Question 660
The SOC needs to count unique destination domains rather than return the domains themselves. Which response best meets the security operations requirement?
Explanation
Correct Answer
Distinct cardinality aggregation answers a count question rather than producing a value list. This directly addresses the requirement to estimate unique contacted domains.
Incorrect Answers
A set removes duplicates and does not preserve full event chronology. This addresses preserve repeated command evidence; it does not directly satisfy estimate unique contacted domains.
Very large dynamic arrays are poor substitutes for targeted event investigation. Its intended use is to constrain oversized KQL collections, whereas this case requires the analyst to estimate unique contacted domains.
Make_set produces distinct collection elements. That action focuses on list unique source IPs per user rather than the specified need to estimate unique contacted domains.
