Each event receives a(n) from splunk. (select all that apply.)

Each event receives a(n) key=value pairs from Splunk.

Field discovery occurs at search time. It is the process by which Splunk Enterprise recognizes and extracts key=value pairs from event data at search time.Internal fields such as raw and time must be specifically removed with the fields command; simply not including them in the fields and also does not exclude them from extraction. 

Each event receives a(n) key=value pairs from Splunk.

Explanation:

The method by which Splunk Enterprise extracts key=value couples from event data at search time.  When field discovery is approved, Splunk Enterprise:

Extracts the first 50 fields in the event data that match simple key=value pairs. Extracts any fields that you explicitly specify in the search. Performs custom field extractions that you define within the Field Extractor, the Extracted Fields  page, configuration files, or search commands.
