Explanation:
The results will form a hierarchy of folders for each partition key. - Yes The resulting file partitions can be read in parallel across multiple nodes. - Yes The resulting file partitions will use file compression. - No Partitioning data by columns such as year, month, and day, as shown in the DataFrame write operation, organizes the output into a directory hierarchy that reflects the partitioning structure. This organization can improve the performance of read operations, as queries that filter by the partitioned columns can scan only the relevant directories. Moreover, partitioning facilitates parallelism because each partition can be processed independently across different nodes in a distributed system like Spark. However, the code snippet provided does not explicitly specify that file compression should be used, so we cannot assume that the output will be compressed without additional context.

Explanation:

We are analyzing the query:
SELECT e.[WWI Employee ID],
e.Employee,
e.[Preferred Name],
gdr.[WWI Employee ID] AS [Direct Report ID],
gdr.Employee AS [Direct Report]
FROM Dimension.Employee AS e
OUTER APPLY Dimension.GetDirectReports(e.[Employee Key]) AS gdr;
Key concepts:
APPLY operator : Used to join a table with a table-valued function .
OUTER APPLY ensures all rows from the left (Employee) are returned, even if the function returns no rows (similar to LEFT JOIN).
Table-valued function (TVF) : Returns a set of rows (unlike scalar functions, which return a single value).
The function executes once per row from the left table, not once for the whole query.
Evaluating each statement:
" Dimension.GetDirectReports is a scalar T-SQL function. "
No # It must be a table-valued function , because OUTER APPLY requires a table expression.
" The Dimension.GetDirectReports function will run only once when the query runs. " No # With APPLY , the function runs for each row of Dimension.Employee .
" The output rows will include at least one row for each row in the Dimension.Employee table. " Yes # Because of OUTER APPLY , every employee row is included, even if there are no direct reports (in that case, the columns from gdr will be NULL).
Scalar function # No
Runs once per query # No
At least one row per Employee # Yes

Requirement Analysis
Sales table # Users should only see sales data for their own region .
This requires filtering rows based on a condition (e.g., Region = User's Region).
The correct feature: Row-level security (RLS) .
Employees table # Restrict access to Personally Identifiable Information (PII) while allowing access to non- sensitive columns.
This requires restricting access to specific columns (such as SSN, phone, address, etc.), but leaving others visible.
The correct feature: Column-level security .
Maintain access to unrestricted data for all users # Both RLS and column-level security allow users to continue accessing non-restricted data.
Why Other Options Are Not Correct
Item permissions : Control access at the object level (e.g., table or report), not at the row or column level. Too coarse for this requirement.
Workspace permissions : Apply at the workspace level, not suitable for table-level data filtering.
Completed Answer
Employees # Column-level security
Sales # Row-level security (RLS)
