CompTIA Data+ DA0-002 (V2) Practice Question

A marketing analyst receives a daily orders file named orders_2025-08-28.json from an internal API. Each JSON record represents a single order and contains a line_items array; every element of line_items is itself an object that holds product_id, quantity and unit_price. The analyst must ingest the data into a relational reporting table that has one row per order. Based on the characteristics of the .json format, which technical challenge is the analyst MOST likely to face during the load?

  • Translating 64-bit integers from big-endian to little-endian format before they can be stored in the database.

  • Converting extended characters because JSON lacks native support for Unicode (UTF-8) encoding.

  • Decompressing the mandatory GZIP compression that JSON applies to all text files.

  • Flattening hierarchical objects and arrays that do not map cleanly to a two-dimensional row-and-column structure.
