SPLK-1002 Advanced Visualization and Lookups Practice Question
An IT administrator notices that a lookup table used to enrich firewall logs is not updating correctly. The lookup file is stored in $SPLUNK_HOME/etc/apps/search/lookups/. What is the most likely cause if the lookup is defined as a 'file-based lookup' with automatic lookup?
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 filename contains a space character
Splunk does not support spaces in lookup filenames. A space in the filename causes the lookup to fail. Option C is correct.
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 is too large (over 100 MB)
Why it's wrong here
File size does not prevent updates, though performance may suffer.
- ✗
The lookup is not referenced in any search
Why it's wrong here
Automatic lookups apply to all searches matching the source type, so no explicit reference is needed.
- ✓
The lookup filename contains a space character
Why this is correct
Spaces in lookup filenames are not supported by Splunk.
- ✗
The lookup file permissions are set to read-only
Why it's wrong here
Read-only permissions still allow reads, but updates would fail; automatic lookup only reads the file.
