Question 29
Section 1A company wants to prepare data for a generative AI project. Which dataset is the best example of structured data?
Correct answer: B
Explanation
Structured data is organized into a predefined format such as rows and columns, while unstructured data lacks that fixed schema and includes content like free text, images, audio, or video. — Source material: 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 folder of customer support call recordings saved as audio files
Audio files are unstructured data because they do not follow a predefined row-and-column schema.
B. A table of sales records with fixed columns for date, product, price, and region
Structured data is organized in a predefined format. A table with consistent fields such as date, product, price, and region matches that definition and is a standard real-world example of structured data.
C. A collection of product photos stored in image files by department
Image files are unstructured data even when they are grouped into folders or categories.
D. A set of employee comments from open-ended survey responses
Free-text responses are unstructured data because the content does not fit a fixed schema.
