What is the difference between live and extract connections in Tableau?
Extract connections use databases, while live connections use files
Extract connections are used only for filters
Live connections allow real-time updates, while extracts store static snapshots of data
Live connections are faster than extracts
Correct Answer: C — Live connections allow real-time updates, while extracts store static snapshots of data

What is a "Heatmap" in Tableau?
A chart showing trends over time
A tool for combining data sources
A graphical representation of data using colors to show density
