In what order arc the following knowledge objects/configurations applied?

The correct answer is B. Field Extractions, Field Aliases, Lookups. Splunk applies knowledge objects at search time in this sequence: Field Extractions → Field Aliases → Lookups. First, raw field values are extracted from events. Then, field aliases rename those extracted fields. Finally, lookups use the (possibly aliased) fields to enrich…

Explanation

Splunk applies knowledge objects at search time in this sequence: Field Extractions → Field Aliases → Lookups. First, raw field values are extracted from events. Then, field aliases rename those extracted fields. Finally, lookups use the (possibly aliased) fields to enrich events with additional data from lookup tables. This order matters because each step depends on the output of the previous one - you cannot alias a field that hasn't been extracted yet, and you cannot look up a field that hasn't been extracted or aliased.
