DA0-002 Data Governance Practice Question
An analyst needs to present quarterly sales data to the board. The CEO wants to see both overall trend and breakdown by region. Which dashboard layout is most effective?
⚠ Common exam trap
Test-takers frequently choose a single line chart (Option A) thinking it shows both trend and breakdown, but they overlook that multiple overlapping lines make it hard to see the aggregate trend, which is the CEO's primary need.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A combination of a line chart for total and a stacked area chart for regional breakdown
It simultaneously satisfies the CEO's dual requirement: a line chart clearly shows the overall quarterly sales trend, while a stacked area chart breaks down total sales by region, allowing the board to see both the aggregate performance and the contribution of each region over time. This combination leverages the strengths of each chart type—line for trend clarity and stacked area for part-to-whole relationships—without overloading the viewer with data.
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 single line chart with all regions
Why it's wrong here
A single line chart with multiple lines can be cluttered and hard to read.
- ✗
A KPI card with total sales
Why it's wrong here
A KPI card shows only total sales, missing the regional breakdown.
- ✓
A combination of a line chart for total and a stacked area chart for regional breakdown
Why this is correct
This layout clearly shows the overall trend and regional contributions in a cohesive way.
- ✗
A table with all quarterly figures
Why it's wrong here
A table is dense and not visual, making trends harder to spot.
