SPLK-1001 Using Fields and Lookups Practice Question
Exhibit
Refer to the exhibit. automatic_lookups.conf: [apache_access] lookup_table = geoip GeoIP lookup file has fields: ip, city, country The search: index=web sourcetype=apache_access | head 10 Results show city and country fields with correct values from the GeoIP lookup. However, the search also shows the raw field 'clientip'. What does the automatic lookup do with the input field?
Refer to the exhibit. The search results show city and country fields from the GeoIP lookup. What does the automatic lookup use as the input field to match against the lookup table?
⚠ Common exam trap
Splunk often tests the misconception that automatic lookups automatically use any IP-related field (like `clientip`) or that they append fields without a match, when in fact the default input field for GeoIP lookups is `ip` and must be explicitly configured if the IP data resides in a different field.

Correct answer & explanation
✓
ip
The automatic GeoIP lookup in Splunk uses the `ip` field as the default input field to match against the lookup table. This is because the GeoIP lookup is designed to map IP addresses to geographic locations, and the lookup table expects an IP address as the key. When you configure an automatic lookup, you specify the input field (e.g., `ip`) that corresponds to the lookup table's key field, allowing Splunk to enrich events with location data.
