DA0-002 Data Governance Practice Question
A hospital's data governance committee is drafting a policy that defines who may access patient diagnosis records, how long those records must be retained, and the process for requesting exceptions. Which governance artifact is the committee creating?
⚠ Common exam trap
A common mix-up: candidates confuse documentation artifacts that describe data with governance artifacts that prescribe rules, leading to choosing a dictionary or lineage diagram.

Correct answer & explanation
✓
A data policy
The committee is defining rules about access, retention, and exceptions, which are the substance of a data policy. Policies articulate what is required and who is accountable, while supporting artifacts like dictionaries, lineage diagrams, and scorecards describe data structure, movement, or quality. Only a policy establishes the binding governance framework the committee is drafting.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A data quality scorecard
Why it's wrong here
A quality scorecard measures dimensions such as completeness, accuracy, and timeliness against thresholds. It reports on data health rather than governing access or retention. The committee's questions about permissions and retention periods fall outside the scope of quality metrics, which assume the data is already properly governed.
- ✗
A data dictionary
Why it's wrong here
A data dictionary documents metadata such as field names, data types, and allowable values. It describes what data exists, not who may access it or how long it is kept. While valuable for governance, it does not establish access rules, retention periods, or exception procedures, which are policy-level decisions rather than structural documentation.
- ✓
A data policy
Why this is correct
A data policy is a formal statement of rules governing data access, retention, and exception handling. It codifies the committee's decisions about who can view diagnosis records, how long they persist, and how deviations are approved. This artifact provides the authoritative framework that procedures and controls then implement across the organization.
- ✗
A data lineage diagram
Why it's wrong here
A lineage diagram traces data from source systems through transformations to final reports. It answers where data came from and how it changed, not who may access it or how long it is retained. While useful for impact analysis and compliance auditing, lineage documentation does not define access permissions or retention rules.
