Practice Questions 1

An online marketplace ingests daily .csv files of customer shipping addresses with columns Door_No, Street_Name, City, and Zip_Code. The analytics team wants a single column that stores these fields as one JSON object (see the attached image for the desired format). The team wants the least coding effort. Create a new column that nests the four fields into a single JSON object using a low/no-code approach. Which solution meets the requirement with the LEAST coding effort?

NEST_TO_ARRAY combines values into an array, not a JSON object with keys such as Door_No and City. Trap: It is a nesting transform, but the output shape is wrong.
DataBrew NEST_TO_MAP creates one map/object column from the selected address columns with minimal code.
PIVOT changes row/column orientation for analysis-style reshaping; it does not create a nested address JSON object from selected columns. Trap: It is a DataBrew transform, but it solves a different data-shaping problem.
A Python Lambda could build the dictionary, but it is custom code and violates the least-coding, low/no-code requirement. Trap: The output could be correct, but the implementation effort is not.
