Which statement about the Schema (From Table) reader is true?

• A. It restricts attribute definition to a single data type.
• B. It allows you to choose which columns define attribute names and data types.
• C. It cannot be used with Excel sources.
• D. It automatically writes to a CSV writer.

Answer: (B)

This item tests how the Schema (From Table) reader builds a feature schema from a tabular source. It gives you direct control over which columns become attributes and what data type each attribute should have, so you can tailor the output to fit downstream needs. Because you can select different columns to define attribute names and assign appropriate types to each one, you’re not limited to a single data type. Excel sheets are just tabular sources with columns, so this reader can be used with Excel data as well. It doesn’t automatically write to a CSV writer; you’d need a separate writer stage to output to CSV.
