Exam SPLK-1001 topic 1 question 47 discussion

The correct answer is: D. Splunk automatically discovers many fields based on sourcetype and key/value pairs found in the data. ✅ 📌 Explanation: Splunk uses automatic field extraction during indexing and searching: It relies on the sourcetype to determine how data is structured. It scans for key/value patterns (like user=john, status=200) and extracts fields accordingly. These extracted fields appear in the Fields Sidebar during a search. 🚫 Why the others are incorrect: A: Time range (like last 24 hours) doesn't affect field extraction. B: Users can manually define fields, but Splunk does automatic extraction too. C: Visualizations don’t drive field extraction—field data enables visualizations.

D is correct. B may seem correct but according to the pdf pg. 77, Prior to search time, some fields are already stored with the event in the index: meta fields like host, source, sourcetype and index as well as internal fields such as _time and _raw.

D is correct
