PL-300 Visualize and analyze the data Practice Question

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✓

  The geographic data is not categorized correctly in the Data pane.

  Why this is correct

  The Power BI Map visual relies on Bing Maps to geocode location values, and it can only do that if each geographic field has the correct Data Category set in the Column tools (e.g., Country, State, City). If the field is left as 'Uncategorized', Bing may interpret the values as text or fail to resolve them, so entire countries can be omitted. To fix this, select the field in the Fields pane, go to the Column tools tab, and set the Data Category accordingly. This is the most common reason a country that exists in your data does not appear on the map.

• ✗

  The report page filter is excluding those countries.

  Why it's wrong here

  A report page filter could certainly hide data, but it would generally apply to the entire page and would be clearly visible in the Filters pane, so you would know if a country is being filtered out. Additionally, filters are an intentional user action, whereas the symptom described here is an unexpected absence of a country from the map. In practice, when a map shows some countries but not others for no apparent reason, the cause is almost always that the geographic field is not correctly categorized, not a filter. Unless the filter is explicitly set to exclude a specific country, it is not the likely culprit.

• ✗

  The map visual is limited to 30 data points.

  Why it's wrong here

  The Map visual in Power BI does not have a 30-point limit; it can display tens of thousands of data points (the exact limit depends on the map type and performance). The 30-point figure is a common misunderstanding, possibly confused with the 'Show items with no data earlier' setting or with the old 'Shape Map' behavior. Moreover, a limit on data points would not omit an entire country—it would only stop plotting individual points after the threshold, usually the lowest-valued points. Since the question specifies that whole countries are missing, a data point limit is not a plausible explanation.

• ✗

  The map visual only supports US addresses.

  Why it's wrong here

  Power BI's Map visual uses Bing Maps, which is a global geocoding service that recognizes locations worldwide, not just US addresses. If a user sees only US locations, it is because the data itself is US-centric or because the fields are categorized with US-specific categories (e.g., State as 'State/Province'), but Power BI does not prevent plotting international data. The Bing Maps geocoder supports country names, cities, and postal codes across all countries. Therefore, the absence of certain countries cannot be attributed to a US-only limitation of the visual.
