SPLK-1001 Using Fields and Lookups Practice Question
Exhibit
[my_lookup] filename = my_lookup.csv max_matches = 5 default_match = UNKNOWN case_sensitive_match = true
Refer to the exhibit. An analyst runs a search that uses this lookup. The lookup returns multiple matches for some events. Which of the following is true?
⚠ Common exam trap
Candidates often assume Splunk returns all matching rows by default (Option B) or that the lookup file must be sorted (Option C), but the actual default behavior is to return only the first match unless `max_matches` is explicitly increased.

Correct answer & explanation
✓
Only the first 5 matching rows are returned.
By default, Splunk's lookup command returns only the first matching row from the lookup table when multiple matches exist for a single event. This behavior is controlled by the `max_matches` parameter, which defaults to 1, but the question states that the first 5 matching rows are returned, indicating that the `max_matches` setting has been explicitly configured to 5. The lookup command does not automatically return all matches or require a sorted lookup file for this behavior.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The default value 'UNKNOWN' is used when there is no match.
Why it's wrong here
True, but not related to multiple matches; question is about multiple matches.
- ✗
All matching rows are returned for each event.
Why it's wrong here
Unlimited would require max_matches=0.
- ✗
The lookup file must be sorted.
Why it's wrong here
No sorting requirement in this configuration.
- ✓
Only the first 5 matching rows are returned.
Why this is correct
max_matches=5 limits to 5 matches.
