CompTIA Data+ DA0-002 (V2) Practice Question

During a data-quality incident review, an entry-level analyst notices that the "Average Order Value" metric on an executive dashboard spiked immediately after a weekend ETL deployment. Before rolling back the job, the analyst must trace the metric through every upstream table and transformation and see which other dashboards or models would be affected by any fix. Which type of documentation will provide the complete, end-to-end record of how the metric's data is sourced, transformed, and loaded across systems?

  • An end-to-end data lineage document for the metric

  • A hierarchy structure diagram of the order data domain

  • The data dictionary entry that defines the metric's fields

  • The original system-level data-flow diagram created during design
