Refer to the exhibit. The data shown is an example of which data concept?
⚠ Common exam trap
CompTIA often tests the distinction between structured and semi-structured data, trapping candidates who see any organization (like tags in JSON) and mistakenly label it as structured, when the rigid row-and-column format is the key differentiator.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Structured data
The exhibit shows data organized into rows and columns with a fixed schema (e.g., 'Name', 'Age', 'City'), which is the defining characteristic of structured data. Structured data conforms to a predefined data model, typically stored in relational databases or spreadsheets, and can be easily queried using SQL. This tabular format with consistent data types per column is the classic example of structured data.
