SPLK-1001 Using Fields and Lookups Practice Question
Which TWO of the following are valid ways to extract fields in Splunk? (Choose two.)
⚠ Common exam trap
Many candidates confuse the 'fields' command (which filters existing fields) with field extraction commands, or mistakenly think 'regex' is a valid Splunk command when only 'rex' exists.

Correct answer & explanation
✓
Using the Extract New Fields dialog in the UI
The 'Extract New Fields' dialog in the Splunk UI provides a graphical interface to define field extractions using regex patterns, which are then saved as inline or custom field extractions. Option C is correct because the 'rex' command is a dedicated search-time command that extracts fields from raw event data using named capturing groups in a regular expression.
