SPLK-1002 Advanced Visualization and Lookups Practice Question
A team uses a lookup to enrich web logs with customer region. The lookup is file-based and updated daily. Some events are not being enriched even though the lookup file has matching keys. What could be the issue?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The lookup file has leading or trailing spaces in key fields.
Leading or trailing spaces in the lookup file's key field or the search event's field will cause matching to fail silently. Splunk requires exact string matches for lookups, so extra spaces prevent the lookup key from being found. Option A (maximum file size) is incorrect because exceeding maximum size would typically cause an error or truncated results, not a silent failure of matching. Option B (file not sorted) is incorrect because file-based lookups do not require sorting; sorting is only needed for time-based lookups or certain efficient memory modes but not for basic matching. Option C (wrong timestamp format) is irrelevant because this lookup is for region enrichment based on a key field, not a time-based lookup.
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 file exceeds the maximum size.
Why it's wrong here
Exceeding size limits typically causes an error message, not partial enrichment.
- ✗
The lookup file is not sorted.
Why it's wrong here
File-based lookups do not require sorting; Splunk scans the entire file.
- ✗
The lookup definition uses the wrong timestamp format.
Why it's wrong here
Timestamp format is irrelevant unless the lookup is time-based, which it is not.
- ✓
The lookup file has leading or trailing spaces in key fields.
Why this is correct
Extra spaces prevent exact matches; stripping spaces is recommended.
