The answer is to create a calculated column that maps state abbreviations to full names using a SWITCH statement. This is correct because Power BI’s map visuals rely on geographic recognition of standard place names like "California," not two-letter codes like "CA"; a SWITCH function in DAX can transform each abbreviation into its full name, ensuring the map correctly plots every state. On the PL-300 exam, this scenario tests your ability to handle data preparation for geospatial visuals, often appearing as a distractor where candidates mistakenly choose the "Data category" property, which only tags the field type without altering the actual values. A common trap is assuming a filled map will bypass the issue, but it suffers from the same recognition limitation. Memory tip: think "SWITCH the code to the name" to fix missing map states.
PL-300 Visualize and analyze the data Practice Question
This PL-300 practice question tests your understanding of visualize and analyze the data. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 Power BI report that displays sales data by region. The report includes a map visual showing sales amount by state. You notice that some states are not displayed on the map because the state names in the data do not match the standard names used by Power BI's map visualization. For example, 'California' is correct but 'CA' is not recognized. You need to ensure all states appear correctly. Which action should you take? A. Create a calculated column that maps state abbreviations to full names using a SWITCH statement. B. Change the map visual to a filled map. C. Use the 'Data category' property to set the field to 'State or Province'. D. Add a custom map image. Which option is the best?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a calculated column that maps state abbreviations to full names using a SWITCH statement
Option A is correct because you can create a calculated column that converts abbreviations to full names using a SWITCH or a mapping table. Option B is wrong because a filled map has the same recognition issue. Option C is wrong because setting data category does not change the values. Option D is wrong because custom map images require additional setup and may not solve the recognition issue.
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.
✗
Use the 'Data category' property to set the field to 'State or Province'
Why it's wrong here
Data category only hints the type; it doesn't correct values.
✓
Create a calculated column that maps state abbreviations to full names using a SWITCH statement
Why this is correct
This corrects the values to be recognized by the map.

✗
Add a custom map image
Why it's wrong here
Not needed; the built-in map can work with correct names.
✗
Change the map visual to a filled map
Why it's wrong here
Filled map also requires recognized location names.

TExam Day Tips
→Underline the problem statement mentally.
→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.
