CERTIFIED-DATA-ANALYST-ASSOCIATE Question #38: Real Exam Question with Answer & Explanation

Question

An analyst writes a query that contains a query parameter. They then add an area chart visualization to the query. While adding the area chart visualization to a dashboard, the analyst chooses "Dashboard Parameter" for the query parameter associated with the area chart. Which of the following statements is true?

Options

• AThe area chart will use whatever is selected in the Dashboard Parameter while all or the other
• BThe area chart will use whatever is selected in the Dashboard Parameter along with all of the
• CThe area chart will use whatever value is chosen on the dashboard at the time the area chart is
• DThe area chart will use whatever value is input by the analyst when the visualization is added to
• EThe area chart will convert to a Dashboard Parameter.

Explanation

Option B is correct because linking a query parameter to a Dashboard Parameter creates a shared control: when a user selects a value from the Dashboard Parameter widget, all visualizations on the dashboard that are also linked to that same Dashboard Parameter will update simultaneously - not just the area chart. This is the core purpose of Dashboard Parameters: unified, cross-visualization filtering from a single input.

Why the others are wrong:

• A implies the area chart updates but other visualizations do not - the opposite of how Dashboard Parameters work; the whole point is shared, synchronized control.
• C suggests the value is captured as a one-time snapshot when the chart is added, but Dashboard Parameters are dynamic - they respond to user input at runtime, not at configuration time.
• D implies the analyst hard-codes a static value during setup, which describes a fixed default, not a Dashboard Parameter linkage.
• E is a category error - a visualization cannot "convert" into a parameter; they are separate objects.

Memory tip: Think of a Dashboard Parameter as a remote control for a TV with multiple screens - one button press (one parameter selection) changes all linked visualizations at once. If only one screen changed, it wouldn't be a dashboard parameter - it would just be a query parameter.
