SPLK-1002 · Question #130
Which of the following statements describes calculated fields?
The correct answer is B. Calculated fields are a shortcut for repetitive and complex eval commands.. Calculated fields in Splunk store eval expressions that are automatically applied at search time, acting as reusable shortcuts for complex or repetitive eval commands.

Why each option
Calculated fields in Splunk store eval expressions that are automatically applied at search time, acting as reusable shortcuts for complex or repetitive eval commands.
Calculated fields can operate on any extracted field in an event, not just fields added by lookups; they are not restricted to lookup-derived fields.
A calculated field saves an eval expression that Splunk automatically applies to every event at search time, eliminating the need to retype complex or repetitive eval statements in every search. This makes them a persistent shortcut specifically for eval command logic.
There is no 'calc' command in Splunk SPL; the correct underlying command is 'eval', making this description technically inaccurate.
Calculated fields do not compute moving averages; that functionality requires commands such as trendline or stats with specific functions.
