Identify the Best Practice for Form Accessibility

Which option shows the best way to make a form accessible in a BI dashboard?

A Use labels linked to inputs with <code>for</code> attribute and ensure keyboard navigation.

B Use placeholder text only without labels to keep the form clean.

C Use images as buttons without alt text for visual appeal.

D Disable tab navigation to prevent accidental input changes.

💡 Hint

Think about users who rely on screen readers or keyboard only.

Labels linked to inputs and keyboard navigation ensure all users can interact with the form easily.

Choosing Input Types for Data Filters

You want users to filter sales data by date range and product category in a BI report. Which form input types should you use?

A File upload for dates and slider for product category.

B Text inputs for dates and checkboxes for product category.

C Single text input for date range and radio buttons for product category.

D Two date pickers for start and end date, and a dropdown for product category.

💡 Hint

Consider input types that reduce user errors and improve clarity.

Date pickers help users select valid dates easily, and dropdowns simplify category selection.

Calculate Total Sales for Selected Region Using DAX

Given a sales table with columns Region and SalesAmount, which DAX measure correctly calculates total sales only for the selected region in a slicer?

A Total Sales = CALCULATE(SUM(Sales[SalesAmount]), ALL(Sales[Region]))

B Total Sales = CALCULATE(SUM(Sales[SalesAmount]), VALUES(Sales[Region]))

C Total Sales = SUM(Sales[SalesAmount])

D Total Sales = CALCULATE(SUM(Sales[SalesAmount]), FILTER(ALL(Sales), Sales[Region] = SELECTEDVALUE(Sales[Region])))

💡 Hint

Think about how to respect the slicer selection context.

Using VALUES(Sales[Region]) keeps the filter context from the slicer, summing only selected regions.

Find the Error in This DAX Measure for Average Sales

What error will this DAX measure cause?
Average Sales = AVERAGE(Sales[SalesAmount

Figma

Average Sales = AVERAGE(Sales[SalesAmount])

A TypeError because AVERAGE expects a table, not a column.

B Returns zero because of empty SalesAmount column.

C SyntaxError due to missing closing bracket.

D No error, measure calculates average correctly.

💡 Hint

Check the brackets and syntax carefully.

The measure is missing a closing bracket for the column reference, causing a syntax error.

Understanding Level of Detail (LOD) Expressions in BI Tools

Which statement best describes the purpose of Level of Detail (LOD) expressions in BI tools?

A LOD expressions allow calculations at a specified granularity, independent of the current view filters.

B LOD expressions are used to create visual themes and color palettes.

C LOD expressions automatically refresh data sources in real-time dashboards.

D LOD expressions replace all filters applied by users on reports.

💡 Hint

Think about how to calculate values ignoring or including certain filters.

LOD expressions let you fix the calculation level, like total sales per customer regardless of other filters.
