Tableau Desktop Certified Professional — Question 4

What are three reasons to use joins instead of relationships? (Choose three.)

Answer options

• A. You need to use a specific join type.
• B. You need to create an extract that will have multiple tables.
• C. You need to use row-level security.
• D. You need to use a data model that supports shared dimensions.
• E. You need to connect to multiple databases.

Correct answer: A, C, D

Explanation

The correct answers are A, C, and D because specific join types allow for more complex data manipulation, row-level security is essential for controlling access, and shared dimensions are best supported through joins. Option B is incorrect as extracts can be created with relationships, and option E is not relevant since joins don't inherently require connecting to multiple databases.
