Tableau Desktop Certified Professional — Question 98

You have a data set that builds a union between two tables. You need to extract the data set.

What should you use to extract the data set?

Answer options

• A. physical tables that use a single table extract
• B. physical tables that use multiple table extracts
• C. logical tables that use a single table extract
• D. logical tables that use multiple table extracts

Correct answer: B

Explanation

The correct choice is B, as physical tables that utilize multiple table extracts are necessary to effectively combine and extract data from both tables in a union. Options A and C are incorrect because they limit the extraction to a single table, which does not fulfill the requirement of uniting two tables. Option D, while using logical tables, also limits the extraction to a single table, making it unsuitable.
