Some reader parameters affect how feature types are created. Therefore, they can only be set when adding the reader.

• A. False
• B. True
• C. Sometimes
• D. Never

Answer: (B)

Some reader parameters shape how the initial data schema (feature types) is created as the data is read. Because the feature types are inferred during that first read, those settings have to be specified when you add the reader. If you change them later, the existing feature types aren’t automatically re-created to reflect the new settings; you’d typically need to re-read by re-adding the reader (or re-run with the same reader in a fresh read) to update the schema. That’s why these parameters are effectively set at the time the reader is added.
