DA0-002 Data Quality Practice Question
A data audit reveals that some numbers in the "Revenue" column were manually entered from PDF invoices. This introduces potential errors. Which data concept is being addressed?
⚠ Common exam trap
Candidates may see the mention of 'audit' and 'origin' and incorrectly choose data lineage. However, the key issue is the potential errors from manual entry, which is a data quality concern. The audit is identifying a quality problem, not tracing the data's path.

Correct answer & explanation
✓
Data quality
The scenario describes a data audit that identifies potential errors from manual data entry from PDF invoices. This directly relates to data quality, which assesses aspects like accuracy, completeness, and consistency. The audit is highlighting a quality concern (potential errors), not lineage tracking. Data lineage focuses on the origin and transformation of data, but the primary issue here is the risk of inaccuracies, making data quality the correct concept.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Data lineage
Why it's wrong here
Data lineage tracks the origin and transformation of data, but this scenario is about potential errors affecting accuracy, which is a data quality dimension. The audit identifies a quality issue, not a lineage need.
- ✓
Data quality
Why this is correct
Data quality assesses the accuracy, completeness, and reliability of data. Manual entry from PDF invoices introduces potential errors, directly impacting data quality. Thus, this is the correct concept being addressed.
- ✗
Data security
Why it's wrong here
Data security involves protecting data from unauthorized access or breaches. This scenario does not mention security concerns, only potential errors from manual entry.
- ✗
Data governance
Why it's wrong here
Data governance refers to the overall management of data availability, usability, and integrity. While it may include quality processes, the specific focus here is on quality issues, not governance policies.
