What is the role of a data steward in CDX governance?

• A. Writes code to transform data.
• B. Monitors network traffic.
• C. Manages hardware procurement.
• D. Oversees data quality, privacy, usage policies, and metadata management for assigned data domains.

Answer: (D)

The role being tested is the governance-focused function of a data steward. In CDX governance, a data steward is responsible for the ongoing stewardship of data within assigned domains: ensuring data quality, protecting privacy, enforcing usage policies, and managing metadata. This means establishing and upholding data quality standards, monitoring data for accuracy and consistency, making sure privacy and regulatory requirements are met in how data is stored and shared, and maintaining metadata such as definitions, lineage, and the data catalog so people understand what the data means and where it came from. They work with data owners and data producers to keep data reliable, discoverable, and compliant across the organization.

Transforming data, monitoring network traffic, and procuring hardware are handled by other roles. Writing code to reshape or move data is an ETL or data engineering task. Monitoring networks is an IT security or operations function. Securing or purchasing hardware falls under IT asset management or procurement. Since the data steward’s core responsibility is governance over data quality, privacy, usage policies, and metadata for their domains, that is the best fit.
