SPLK-1001 Using Fields and Lookups Practice Question
A Splunk user wants to see a list of all fields that are extracted from events of sourcetype 'apache_access'. They need to know which fields are available for use in searches and lookups. Which command should they use to discover all fields automatically extracted by Splunk for that sourcetype?
⚠ Common exam trap
Many candidates confuse the `extract` command (which re-extracts fields) with the `fields` command (which lists field names), or they mistakenly think `inputlookup` can display event fields instead of lookup table columns.

Correct answer & explanation
✓
Use the search 'sourcetype=apache_access | fields' to list all fields in a few sample events
The `| fields` command, when used without arguments, lists all fields present in the search results. By searching `sourcetype=apache_access` and piping to `| fields`, Splunk returns a table of all extracted fields (both default and custom) from the events of that sourcetype, allowing the user to see which fields are available for searches and lookups.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Use the search 'sourcetype=apache_access | fields' to list all fields in a few sample events
Why this is correct
Running a search and using 'fields' command shows all fields present in the results.
- ✗
Use the 'extract' command with no arguments to show all extracted fields
Why it's wrong here
extract is used for custom field extraction, not to list existing fields.
- ✗
Use the 'regex' command with a capturing group to identify fields
Why it's wrong here
regex is not used to list fields.
- ✗
Use the 'inputlookup' command to display field names
Why it's wrong here
inputlookup is for viewing lookup tables, not event fields.
