DA0-002 Data Governance Practice Question
A data analyst creates a report showing sales by product category. The analyst notices that one category has a very high sales figure due to a one-time bulk order. Which of the following is the best way to communicate this insight to stakeholders?
⚠ Common exam trap
Candidates often think removing or hiding data (options A and C) simplifies the message, but the exam tests the principle that data communication must be transparent and preserve the full context for decision-making.

Correct answer & explanation
✓
Add a note to the chart explaining the bulk order.
It maintains data integrity while providing necessary context. Adding a note to the chart allows stakeholders to understand the anomaly without distorting the underlying data. This approach aligns with best practices in data communication, where transparency about outliers is critical for accurate interpretation.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Delete the bulk order from the dataset.
Why it's wrong here
Deleting the transaction falsifies the dataset and destroys the audit trail stakeholders may need to verify totals. The insight should be communicated by annotating the chart or adding commentary that isolates the one-time order. Deletion would be appropriate only for genuinely erroneous or duplicate records, not legitimate sales.
- ✓
Add a note to the chart explaining the bulk order.
Why this is correct
Annotating the chart identifies the one-time bulk order as the cause of the spike, preventing stakeholders from misreading it as sustained demand. This preserves the accurate sales figure while supplying the context needed for sound decisions.
- ✗
Remove the category with the bulk order from the report.
Why it's wrong here
Removing the category hides legitimate revenue and misrepresents the product mix, preventing stakeholders from seeing the underlying trend. The correct approach is to flag the bulk order as an outlier within the existing category. Removing a category would be right only if it were irrelevant to the analysis question.
- ✗
Use a pie chart to show the proportion of each category.
Why it's wrong here
A pie chart encodes each category as a slice of a whole, so a single bulk order inflates one slice and the distortion cannot be annotated or scaled away. Pie charts suit showing stable part-to-whole composition across few categories, not flagging an outlier that needs contextual explanation.
