Enabling extract encryption at the server level to ensure all extracts are encrypted, regardless of their content Implementing extract encryption in Tableau Server should involve enabling encryption at the server level. This ensures that all extracts stored on the server are encrypted, providing a consistent layer of security across all data, regardless of its sensitivity. This approach helps protect against unauthorized access to extract data stored on the server. Option A is incorrect because selectively encrypting extracts can lead to inconsistencies in security and potential vulnerabilities. Option C is incorrect as database-level encryption does not protect extracts once they are exported from the database. Option D is incorrect because manual encryption of each extract is in-efficient and not scalable, and Tableau Server provides its own encryption mechanism for extracts.
