DA0-002 Data Concepts and Environments Practice Question
Which TWO of the following are considered internal data sources within an organization?
⚠ Common exam trap
It's easy for candidates to confuse 'data used internally' with 'internal data source,' mistakenly selecting options like social media feeds or third-party reports because the organization uses them for analysis, even though they originate externally.

Correct answer & explanation
✓
Employee payroll data
Employee payroll data (B) is generated and stored internally by an organization's HR or finance systems, making it an internal data source. Sales transaction records (D) are also generated internally through the organization's sales processes. Both are proprietary and not accessible from outside, fitting the definition of internal data. In contrast, social media feeds (A), government census data (C), and third-party market research (E) originate externally and are therefore external data sources.
