SPLK-1001 Practice Question: A Splunk admin is troubleshooting a slow report…
A Splunk admin is troubleshooting a slow report that uses an accelerated data model. The report uses tstats commands and filters on a field that is not a constraint field in the data model. Which of the following best explains why the report is slow?
⚠ Common exam trap
Test-takers frequently assume `tstats` always uses acceleration regardless of the fields involved, but Splunk specifically restricts acceleration to constraint fields defined in the data model.
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 field used in the filter is not defined as a constraint field in the data model, so tstats cannot use acceleration for that filter.
C is correct because `tstats` relies on acceleration summaries that are built only for fields defined as constraint fields in the data model. When a filter is applied on a non-constraint field, `tstats` cannot use the pre-computed acceleration summary and must fall back to scanning the raw events, which significantly degrades performance.
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The acceleration summary for that data model has not been rebuilt recently, causing outdated data.
Why it's wrong here
Outdated summary would affect accuracy, not speed.
- ✗
The report is using the data model incorrectly; it should use |datamodel instead of |tstats.
Why it's wrong here
tstats is the recommended way to search accelerated data models.
- ✓
The field used in the filter is not defined as a constraint field in the data model, so tstats cannot use acceleration for that filter.
Why this is correct
Filtering on non-constraint fields forces full event search.
- ✗
The time range is too broad, causing the acceleration summary to include too many events.
Why it's wrong here
Broad time range might be slower but not specifically due to field type.
