Your question is Tableau Performance and Security. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How would you optimize a Tableau dashboard that is performing slowly, and what steps would you take to identify and resolve performance bottlenecks? Can you explain the difference between using joins and relationships in Tableau, and when you would use one over the other? Describe a scenario where you used LOD expressions in Tableau to solve a complex calculation. How did it improve the analysis? How do you implement Row-Level Security (RLS) in Tableau to ensure that users only see data relevant to them?
