DA0-002 Data Governance Practice Question
During a data presentation, an audience member questions the accuracy of the data shown. Which of the following is the best way for the analyst to respond?
⚠ Common exam trap
It's easy for candidates to choose Option C, thinking that providing raw data is sufficient, but they overlook that raw data without transformation documentation does not prove accuracy and may even raise more questions about how the data was prepared.

Correct answer & explanation
✓
Provide documentation of data sources and transformation steps
Providing documentation of data sources and transformation steps directly addresses the audience member's concern about accuracy by demonstrating transparency and traceability. This approach aligns with best practices in data governance, as it allows the audience to verify the data lineage and any ETL processes that may have introduced errors. It also builds trust by showing the analyst has a clear understanding of the data pipeline.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Provide documentation of data sources and transformation steps
Why this is correct
Supplying documentation of sources and transformation steps lets the questioner independently verify lineage, directly addressing the accuracy challenge with evidence rather than assertion. This traceability demonstrates the figures were derived through auditable, repeatable processes, which is the defensible response when data credibility is questioned during a presentation.
- ✗
Change the topic
Why it's wrong here
Changing the topic evades the accuracy challenge entirely, signalling that the analyst cannot defend the figures and undermining trust in the whole presentation. Redirecting discussion is legitimate only when the question falls outside the presentation's agreed scope and a separate forum is arranged.
- ✗
Offer to send the raw data later
Why it's wrong here
Promising raw data later defers the accuracy question instead of addressing it during the presentation, leaving the audience's doubt unresolved. Sharing underlying data suits a detailed post-session audit request, not an immediate challenge requiring the analyst to explain methodology and sources on the spot.
- ✗
Dismiss the question and continue
Why it's wrong here
Dismissing the question leaves the accuracy concern unresolved and damages the analyst's credibility with the audience. Acknowledging the query and offering to verify the figures is the expected professional response. Dismissal suits only a hostile, bad-faith interruption where engagement would derail the entire presentation.
