CompTIA Data+ DA0-002 (V2) Practice Question

Analysts at a retail company frequently download local copies of the nightly_sales dataset from the enterprise data lake, only to discover later that a more current edition already exists. The data-engineering team wants to stop this duplicate-file problem by publishing metadata in the data catalog that can immediately tell users whether they are looking at the authoritative, most recent copy of a dataset. According to accepted metadata management practices, which catalog capability should be implemented first to meet this goal?

  • Record a globally unique dataset identifier and explicit version number for every edition

  • Apply role-based access controls that restrict downloading of raw data files

  • Display an automated lineage graph that visualizes upstream and downstream transformations

  • Link each dataset to standardized business-glossary definitions for its fields
