The correct answer is B. Delimiters. This is because the delimiters method is designed for structured event
data, such as data from files with headers, where all of the fields in the events are separated by a common
delimiter, such as a comma or space. You can select a sample event, identify the delimiter, and then rename
the fields that the field extractor finds.You can learn more about the delimiters method from the Splunk
documentation1. The other options are incorrect because they are not suitable for comma-separated data. The
regular expression method works best with unstructured event data, where you select and highlight one or
more fields to extract from a sample event, and the field extractor generates a regular expression that matches
similar events and extracts the fields from them. The eval expression is a command that lets you calculate new
fields or modify existing fields using arithmetic, string, and logical operations. The table extraction is a feature
that lets you extract tabular data from PDF files or web pages.You can learn more about these methods from
the Splunk documentation23.
