The correct answer is to configure the visual's tooltip to display the value. This is because tooltips in Power BI are the default mechanism for revealing granular data on hover, allowing users to see the exact sales figure without permanently cluttering the line chart with labels. When you hover over a data point, the tooltip dynamically surfaces the underlying measure, making it the most intuitive and interactive way to show values on hover. On the PL-300 exam, this concept tests your understanding of visual formatting and user experience design—a common trap is assuming you need to add data labels or a separate card visual, but the tooltip is the built-in, lightweight solution. Remember, if the tooltip has been customized or removed, you must re-enable it in the visual’s formatting pane under the Tooltips section. Memory tip: think of the tooltip as a “hover helper”—it reveals the number only when needed, keeping your chart clean and your exam answer correct.
PL-300 Visualize and analyze the data Practice Question
This PL-300 practice question tests your understanding of visualize and analyze the data. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
You have a report with a line chart showing monthly sales. Users need to see the exact sales value when they hover over a data point. What should you configure?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure the visual's tooltip to display the value.
Option B is correct because tooltips in Power BI are designed to show detailed information about a data point when the user hovers over it. By default, the visual's tooltip already includes the value, but if it has been customized or removed, you need to ensure the tooltip is configured to display the sales value. This provides an interactive way to see exact numbers without cluttering the chart with permanent labels.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Enable data labels on the chart.
Why it's wrong here
Data labels permanently show values; tooltips appear on hover.
✓
Configure the visual's tooltip to display the value.
Why this is correct
The default tooltip already shows the value; if it's not showing, ensure the tooltip is enabled.

✗
Add a report page tooltip.
Why it's wrong here
Report page tooltips require a separate page; the default tooltip already shows the value.
✗
Set the category label to show the value.
Why it's wrong here
Category labels show the category, not the value on hover.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse data labels (which show values permanently on the chart) with tooltips (which show values on hover), leading them to select option A instead of understanding that tooltips are the correct interactive mechanism for this requirement.

Detailed technical explanation
How to think about this question
In Power BI, each visual has a default tooltip that automatically displays the primary measure value for the hovered data point. This tooltip is part of the visual's 'Tooltips' card in the formatting pane, where you can add or remove fields. The default behavior is to show the value, but if a user has removed the measure from the tooltip or added other fields, the exact sales value might not appear. Configuring the visual's tooltip ensures the measure is included, providing a clean, on-demand display without permanent labels.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
