SPLK-1002 Advanced Searching and Statistics Practice Question
Exhibit
Refer to the exhibit. ``` | tstats summariesonly=t count from datamodel=Authentication.Authentication where Authentication.action=failure by Authentication.src ```
Refer to the exhibit. The search returns results quickly but shows zero events for some src values. What does `summariesonly=t` imply?
⚠ Common exam trap
Splunk often tests the misconception that `summariesonly=t` makes searches 'faster but less accurate,' when in reality it strictly limits the data source to summaries, and accuracy depends on summary completeness, not the option itself.

Correct answer & explanation
✓
It restricts tstats to only use data from accelerated data model summaries.
`summariesonly=t` in a `tstats` command restricts the search to only use data from accelerated data model summaries, ignoring raw event data. This is why the search returns quickly but shows zero events for some `src` values—those values are not present in the accelerated summaries, so they are excluded from the results.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
It restricts tstats to only use data from accelerated data model summaries.
Why this is correct
This is the purpose of summariesonly=t; if acceleration is not complete, some data may be missing.
- ✗
It causes tstats to search the index directly.
Why it's wrong here
tstats always searches data model acceleration; summariesonly=t restricts to summaries only.
- ✗
It makes the search run faster but less accurate.
Why it's wrong here
It is accurate for accelerated data, but data outside acceleration is ignored.
- ✗
It forces tstats to return all events, including those not in summaries.
Why it's wrong here
summariesonly=t excludes non-accelerated data.
