SPLK-1002 Advanced Visualization and Lookups Practice Question
Which two methods can reduce the resource consumption of a large CSV lookup in Splunk? (Choose 2)
⚠ Common exam trap
Many exam-takers assume compressing the CSV file (Option A) would reduce resource consumption, but Splunk cannot read compressed CSV files natively, making this an invalid optimization.
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
✓
Use the lookup command to only return required fields
Using the `lookup` command with a field list (e.g., `| lookup mylookup.csv field1 OUTPUT field2 field3`) reduces resource consumption by only loading the specified output fields into memory, rather than the entire CSV lookup. This minimizes memory usage and I/O overhead, especially for large CSV files with many columns.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Convert the CSV to a gzip file and reference it
Why it's wrong here
Splunk does not support compressed CSV lookups.
- ✗
Increase the max_match parameter
Why it's wrong here
Increasing max_match can increase resource consumption.
- ✗
Use a time-based lookup to limit matches by time
Why it's wrong here
Time-based lookups may not apply to static CSV data.
- ✓
Use the lookup command to only return required fields
Why this is correct
Limiting output fields reduces data transfer and processing.
- ✓
Use a KV Store lookup with a smaller data set
Why this is correct
KV Store can be more efficient for large lookups.
