Question
What command will eliminate duplicates from a query?
A. rmdup
B. stats dc ()
C. dedup
D. accum
Answer
To eliminate duplicates from a Splunk query result, the correct command to use is:
C. dedup
Explanation
The dedup command removes duplicate events from the search results. It looks at all of the fields for each event, and if two events have identical values for all fields, it removes the duplicate, keeping only one instance of that event.
For example, if you run a query like:
sourcetype=”access_combined” | dedup clientip
This will remove any events that have the same clientip field value, so you only see one event per unique client IP address.
The other options are incorrect:
A. rmdup is not a valid Splunk command
B. stats dc() can show you the distinct count of a field, but doesn’t eliminate duplicates from the results
D. accum is used for performing rolling statistics, not deduplication
So in summary, dedup is the go-to command when you need to remove duplicate events and only see distinct results based on one or more specified fields. It’s an important command to know for the CrowdStrike CCFH-202 exam and for Splunk querying in general.
