Tableau Desktop Certified Professional — Question 110

What are two benefits of using a live connection to a data source as compared to an extract? (Choose two.)

Answer options

• A. A live connection to a database server requires less network overhead than an extract.
• B. A workbook connected to a live connection will have fresher data than a workbook connected to an extract.
• C. A live connection reduces the amount of memory used on a client computer as compared to an extract.
• D. A live connection is always faster than an extract.

Correct answer: B, C

Explanation

Option B is correct because a live connection ensures that the data is current, reflecting real-time updates. Option C is also correct since a live connection typically utilizes less memory by not storing a separate extract on the client. Meanwhile, options A and D are incorrect; a live connection may not necessarily require less network overhead, and it is not guaranteed to be faster than an extract.
