Question 7
Section 1A team is preparing data for a generative AI project. Which dataset is the best example of unstructured data?
Correct answer: C
Explanation
Structured data is organized into a predefined format such as rows and columns, while unstructured data does not follow a fixed schema and often includes free-form content like text, images, audio, or video. — Identifying the differences between structured and unstructured data, and identifying real-world examples of each type.
Why each option is right or wrong
A. A spreadsheet of customer records with fixed columns for name, ID, and balance
Structured data uses a predefined schema such as fixed columns and consistent fields.
B. A database table of product inventory with one row per item and set field types
Structured data is organized into rows, columns, and defined data types.
C. A collection of recorded support calls stored as audio files for later analysis
Audio files do not follow a predefined row-and-column schema, so they are unstructured data. In this dataset, the support calls are stored as recordings rather than fixed fields, which makes them the best example of unstructured data under the distinction given in the source material.
D. A sales report where each transaction is stored in a consistent set of numbered fields
Consistent numbered fields indicate a predefined structure rather than free-form content.
