Which role is responsible for the technical aspects of data management, including protection, transport, and storage of data?

• A. Data Steward
• B. Data Custodian
• C. Master Data Management
• D. NOSQL

Answer: (B)

Data Custodian is the role that handles the technical side of data management. This person or team puts into practice the protections, movement, and storage of data. They implement security controls like access management and encryption, ensure data can be transferred securely between systems, and manage storage policies, backups, archiving, and data lifecycle. In short, they translate governance and protection requirements into the actual infrastructure and operations that keep data safe and available. Data Steward focuses on the business side—what the data means, how quality is defined, and how metadata and governance rules apply—rather than implementing the technical safeguards. Master Data Management is the program or set of processes for maintaining a single source of truth for critical data across the organization, not a single role responsible for technical protection and storage. NOSQL is a database technology, not a governance or stewardship role.
