QuestionQ36

Data Source Connection and Ingestion

What is one reason for creating a formula while ingesting a data stream?

  • A To remove duplicate rows of data from the data stream
  • B To transform a datetime field into a date field for use in data mapping
  • C To add a unique external identifier to an existing ruleset
  • D To concatenate files so they are ingested in the correct sequence
Explanation

A formula field can derive a new field from a data-stream field and use Date as its return type. This supports mapping when a datetime source value must be represented as a date field. Formula fields are intended for derived or hard-coded supplemental data, not for file sequencing, ruleset identifiers, or deduplication.
