~8 min read · 5 practice questions ·
What the exam expects
- Choose between a full and an incremental refresh and configure incremental refresh in the Extract Data dialog before publishing.
- Schedule a refresh for a published workbook or data source on Tableau Server or Tableau Cloud, during or after publishing.
- Keep a Tableau Cloud refresh inside the 7,200-second timeout by shrinking the extract or refreshing incrementally.
- Refresh a published extract of local-network data from Tableau Desktop, and know who can be given the Refresh Extracts capability.
- Key terms: full refresh (replaces every row with the source's current data); incremental refresh (adds rows newer than the last refresh, identified by a column); refresh schedule (a recurring refresh task on the site); timeout limit (the longest a single Cloud refresh may run before it's canceled); Refresh Extracts capability (lets a non-owner trigger a refresh).
