DA0-002 Data Governance Practice Question
A data analyst is building a dashboard that will be used by both executives and operational managers. The executives need high-level summaries, while managers need granular details. Which dashboard design principle should the analyst apply?
⚠ Common exam trap
It's easy for candidates to confuse 'drill-down' with 'separate dashboards' (Option D), thinking that different audiences require entirely different views, when in fact a single interactive dashboard with drill-down capabilities is the standard best practice for serving both summary and detail needs efficiently.

Correct answer & explanation
✓
Design the dashboard with drill-down capabilities from summary to detail.
Drill-down capabilities allow users to start with a high-level summary (e.g., total revenue by region) and then interactively navigate to granular details (e.g., individual transactions) without overwhelming either audience. This design principle supports both executive and operational manager needs within a single dashboard, maintaining clarity and performance by loading only the required level of detail on demand.
