DA0-002 Data Governance Practice Question
A data governance council is reviewing how a national retailer handles its customer master data. The council must document the people and groups accountable for the data across its lifecycle. Which TWO roles should be formally defined in the governance charter to establish clear accountability? (Choose two.)
⚠ Common exam trap
The trap here is equating technical custody of a database with accountability for the business data, which belongs to owner and steward roles.

Correct answer & explanation
✓
Data steward, who applies governance policy day to day by maintaining definitions, quality rules, and issue resolution
Accountability for a data domain is split between a decision-making owner and an operational steward. The owner answers for quality, protection, and use, while the steward executes policy through definitions, quality monitoring, and issue resolution. Infrastructure and support roles such as database administrators, network engineers, and help desk technicians keep systems running but hold no mandate over the business data itself.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Help desk technician, who resets passwords and triages user support tickets
Why it's wrong here
A help desk technician resolves access and support requests, including password resets. This is end-user support, not governance accountability. The technician neither owns customer master data nor stewards its definitions and quality, so including this role in the charter would not establish the lifecycle accountability the council is documenting.
- ✗
Database administrator, who tunes indexes, manages backups, and performs schema migrations
Why it's wrong here
A database administrator keeps the platform running through performance tuning, backup management, and schema changes. That is operational infrastructure work, not accountability for the business meaning, quality, or permitted use of customer master data. Chartering this role would confuse platform custody with data stewardship responsibilities the council is trying to assign.
- ✓
Data steward, who applies governance policy day to day by maintaining definitions, quality rules, and issue resolution
Why this is correct
A data steward operationalizes governance: curating definitions, monitoring quality, resolving discrepancies, and coordinating remediation. Defining this role in the charter connects policy to practice, so customer master data issues have a named operational point of contact rather than languishing without ownership between business and IT teams.
- ✓
Data owner, who is accountable for the quality, protection, and appropriate use of a data domain
Why this is correct
The data owner is the accountable executive or senior manager for a domain, approving access, setting policy, and answering for quality and compliance. Formally chartering this role establishes the decision rights the council needs, ensuring someone is answerable when customer master data is misused, degraded, or subject to regulatory scrutiny.
- ✗
Network engineer, who configures firewalls, routing, and segment isolation for the data center
Why it's wrong here
A network engineer secures connectivity and segments traffic. While important to overall security posture, this role has no mandate over customer data definitions, quality, access approval, or lifecycle governance. Listing it in the governance charter would dilute accountability by mixing infrastructure duties with data accountability that belongs to business-facing roles.
