Exam Analytics-Con-301 Topic 4 Question 3 Discussion

Actual exam question for Salesforce's Analytics-Con-301 exam
Question #: 3
Topic #: 4
Which technique should a Tableau consultant use to make visualizations faster?

Suggested Answer: B Vote an answer

Comprehensive and Detailed Explanation From Exact Extract:
Tableau performance documentation explains that rendering speed is strongly affected by the number of marks that Tableau must draw. Each dimension placed on the Detail shelf increases the granularity of the view and increases the number of marks in the visualization.
Removing unnecessary dimensions:
* Reduces the number of marks
* Reduces rendering time
* Decreases memory and CPU usage
* Improves interactive performance
Option A (Show Relevant Values) can slow performance because Tableau must dynamically calculate relevancy each time filters change.
Option C is incorrect because COUNTD is one of the slowest aggregate functions in Tableau and does not speed visualization.
Option D is incorrect because adding more sheets increases dashboard load time and rendering workload.
Removing unnecessary fields from Detail is a documented best practice for improving visualization speed.
* Tableau Performance Checklist recommending reducing marks and removing unnecessary dimensions.
* Rendering optimization guidance explaining how dimensions on Detail expand mark counts.
* Best practices discouraging overuse of COUNTD.
