SPLK-1002 Advanced Visualization and Lookups Practice Question
A Splunk admin notices that a time-based lookup (defined in transforms.conf with time_range=TRUE) is not returning correct results for events outside the lookup's time boundaries. The lookup file contains rows with a valid time range. What is the most likely cause?
⚠ Common exam trap
Candidates often think the lookup file is missing a time field (Option C) when the question explicitly states it contains valid time ranges, or they may confuse time-based lookup behavior with other lookup types that do not enforce time boundaries.

Correct answer & explanation
✓
The event time is outside the time range defined in the lookup
When a time-based lookup is configured with time_range=TRUE in transforms.conf, Splunk restricts lookup matches to events whose timestamps fall within the time range specified in the lookup file. If an event's timestamp is outside that range, the lookup will not return any results, even if other fields match. This is the most likely cause because the question explicitly states that events are outside the lookup's time boundaries.
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 lookup is defined as an automatic lookup and runs at index time
Why it's wrong here
Automatic lookups run at search time, not index time.
- ✗
The lookup table has max_matches set to 1, limiting matches
Why it's wrong here
Max_matches limits the number of matching rows, but doesn't explain no match.
- ✗
The lookup file does not contain a time field
Why it's wrong here
Time-based lookups require time fields; if they were missing, the lookup would not work at all.
- ✓
The event time is outside the time range defined in the lookup
Why this is correct
Time-based lookups only match events whose _time falls within the row's time range.
