SPLK-1001 Practice Question: During data model creation, an administrator adds…
During data model creation, an administrator adds a calculated field that concatenates `src_ip` and `dest_ip` with a hyphen. Which of the following is a best practice for calculated fields in data models?
⚠ Common exam trap
Splunk often tests the misconception that calculated fields are evaluated at index time (like indexed fields) and therefore improve performance, when in fact they are search-time constructs that add overhead.

Correct answer & explanation
✓
Calculated fields should be used sparingly to avoid impacting search performance.
Calculated fields in data models are evaluated at search time, not index time, meaning they add computational overhead for every search that references them. Using them sparingly is a best practice because excessive calculated fields can degrade search performance, especially in large datasets or when the data model is accelerated. Option B correctly identifies this performance consideration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Calculated fields should only use basic mathematical operations, not string functions.
Why it's wrong here
Calculated fields can use any eval function.
- ✓
Calculated fields should be used sparingly to avoid impacting search performance.
Why this is correct
Excessive calculated fields increase search-time computation.
- ✗
Calculated fields are evaluated at index time, so they improve search performance.
Why it's wrong here
Calculated fields are evaluated at search time, which can slow down searches.
- ✗
Calculated fields are automatically accelerated when the data model is accelerated.
Why it's wrong here
Acceleration only applies to fields in the data model, but calculated fields are not accelerated separately.
