Designing and Implementing Enterprise-Scale Analytics Using Microsoft Azure and Power BI — Question 144

You have a Power BI report that contains a card. The card displays the value for year-to-date revenue.

You need to ensure that screen reader users can read the value when initially interacting with the card. The value must stay updated as the dataset is refreshed.

What should you do?

Answer options

• A. Convert the card into a text box.
• B. Populate the alt text by using conditional formatting with a DAX measure.
• C. Add the value to the chart title text.
• D. Populate the alt text with a static value.

Correct answer: B

Explanation

The correct answer is B because using conditional formatting with a DAX measure allows the alt text to dynamically update based on the current value of the card, ensuring accessibility for screen reader users. Options A and C do not provide the necessary accessibility features, while option D would not allow for the value to change as the dataset is refreshed.
