Splunk Core Certified Power User — Question 19

Which of the following statements describes the use of the Field Extractor (FX)?

Answer options

• A. The Field Extractor automatically extracts all fields at search time.
• B. The Field Extractor uses PERL to extract fields from the raw events.
• C. Fields extracted using the Field Extractor persist as knowledge objects.
• D. Fields extracted using the Field Extractor do not persist and must be defined for each search.

Correct answer: C

Explanation

The correct answer is C because fields extracted by the Field Extractor are stored as knowledge objects, allowing them to be reused. Options A and D are incorrect as A suggests all fields are extracted automatically, while D states that fields must be redefined, contradicting the persistence of fields. Option B is also incorrect since the Field Extractor does not specifically use PERL for extraction.
