To include a property indicating that a table contains personally identifiable information (PII), the TBLPROPERTIES keyword is used in SQL to add metadata to a table. The correct syntax to define a table property for PII is as follows:

CREATE TABLE customersInFrance

USING DELTA

TBLPROPERTIES ( ' PII ' = ' true ' )

AS

SELECT id,

firstName,

lastName

FROM customerLocations

WHERE country = ' FRANCE ' ;

The TBLPROPERTIES ( ' PII ' = ' true ' ) line correctly sets a table property that tags the table as containing personally identifiable information. This is in accordance with organizational policies for handling sensitive information.

Option D retains only orders whose customer identifier matches a row in customers_df. Because customers_df contains only active customers, an inner join acts as a membership filter: orders belonging to active customers match and remain, while orders belonging to inactive customers have no corresponding row and are removed. A left join with orders_df on the left would preserve every order, including orders from inactive customers, unless an additional NULL filter were applied. A left join with customers_df on the left changes the driving dataset and can exclude the required order structure or produce different cardinality. A cross join generates the Cartesian product of both DataFrames and is unrelated to key-based filtering. Therefore, the inner join in option D precisely implements the stated active-customer filtering requirement.

 A serverless SQL endpoint is a compute resource that is automatically managed by Databricks and scales up or down based on the workload. A serverless SQL endpoint can be used to run queries and dashboards without requiring manual configuration or management. A serverless SQL endpoint is only active when it is needed and shuts down automatically when idle, minimizing the total running time and cost. A serverless SQL endpoint can be created and assigned to a dashboard using the Databricks SQL UI or the SQL Analytics API. References:
