The 'group by' function in FortiSIEM aggregates events that share identical values for the specified attributes into a single result row. In the exhibit, all six events have the same values for 'User' (jsmith), 'Source IP' (10.0.1.10), and 'Count' (1). A literal interpretation of the question would mean all six events are combined into a single group, yielding one result.

However, 'One' is not an available option. This suggests a likely error in the question, where the non-unique attribute 'Count' was intended to be a unique attribute like 'Time'. As each event in the exhibit has a unique timestamp, grouping by 'User', 'Source IP', and 'Time' would create a unique group for each event, resulting in six distinct results.

A. Two: This would be the result if there were exactly two unique combinations of the grouping attributes in the dataset.

C. Three: This would be the result if there were exactly three unique combinations of the grouping attributes.

D. Five: This would be the result if there were exactly five unique combinations of the grouping attributes.

E. Four: This would be the result if there were exactly four unique combinations of the grouping attributes.

"Running a Historical Analytics Query". The guide explains the "Group By" functionality: "The query will find all the unique values for the attributes you select

and display them in the query results." This confirms that the number of results corresponds to the number of unique combinations of the 'Group By' attributes. In the case of a unique attribute like 'Time' (eventReceiveTime)

each event would form its own group.

"Event Attributes". This section details the attributes used to describe events. Attributes like user

srcIpAddr

and eventReceiveTime are fundamental. The uniqueness of eventReceiveTime for each distinct event log is a core concept

which supports the reasoning that if 'Time' were used in the grouping

each of the six events would constitute a separate result.
