DA0-002 Data Concepts and Environments Practice Question
An organization wants to assign responsibility for data quality and metadata management. Which role is primarily accountable for defining data standards and ensuring data quality across a specific domain?
⚠ Common exam trap
It's easy for candidates to confuse the data steward with the data owner or data custodian, as many candidates mistakenly think the owner handles domain-level quality or that the custodian defines standards, when in fact the steward is the bridge between business requirements and technical enforcement.
