SPLK-1002 Advanced Searching and Statistics Practice Question
A search is running slowly due to a large data volume. Which TWO modifications are likely to improve search performance? (Select two.)
⚠ Common exam trap
Splunk often tests the misconception that using the transaction or dedup command early in a search improves performance, when in fact these commands are memory-intensive and should be deferred until after data volume is reduced.
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
✓
Reduce the time range of the search.
Reducing the time range limits the volume of data scanned by the search head, directly reducing I/O and processing overhead. This is one of the most effective ways to improve search performance because Splunk must read and filter every event in the specified time window from the index.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use wildcard characters at the beginning of search terms.
Why it's wrong here
Prevents index-based search
- ✗
Use the transaction command to group events.
Why it's wrong here
Transaction uses more memory and CPU
- ✓
Reduce the time range of the search.
Why this is correct
Limits data volume scanned
- ✗
Use the dedup command as early as possible.
Why it's wrong here
Dedup can be expensive on large datasets
- ✓
Use indexed fields instead of search-time extracted fields.
Why this is correct
