Answer: COMMENT "Contains PII"

**Correct Answer: D** **Explanation:** In Databricks SQL, you can add comments to tables using the `COMMENT` clause. The syntax for adding a comment to a table is: ```sql COMMENT 'comment_text' ``` In this specific case, the organization policy requires indicating that the table contains personally identifiable information (PII). The correct way to do this is by using: ```sql COMMENT 'Contains PII' ``` This would make the complete CREATE TABLE statement: ```sql CREATE TABLE customersInFrance COMMENT 'Contains PII' AS SELECT id, firstName, lastName, FROM customerLocations WHERE country = 'FRANCE'; ``` **Why other options are incorrect:** - **A**: Incorrect - There are multiple ways to indicate PII in Databricks, including table comments and TBLPROPERTIES. - **B**: Incorrect - The syntax is wrong. It should be `COMMENT 'PII'` or `COMMENT 'Contains PII'`, not `"COMMENT PII"`. - **C**: Incorrect - The syntax is incorrect. TBLPROPERTIES should be followed by parentheses with key-value pairs, like `TBLPROPERTIES ('contains_pii'='true')`. - **E**: Incorrect - `PII` alone is not valid SQL syntax for table creation. **Best Practice:** While `COMMENT 'Contains PII'` works, a more robust approach for PII indication would be to use `TBLPROPERTIES` with a specific key-value pair, which can be programmatically queried later: ```sql CREATE TABLE customersInFrance COMMENT 'Contains PII' TBLPROPERTIES ('contains_pii'='true') AS SELECT id, firstName, lastName, FROM customerLocations WHERE country = 'FRANCE'; ```
