When adding a writer in FME, in which scenario should you choose Automatic mode for Feature Type Definition?

• A. You do not expect to receive the same schema each time and want to write results regardless of the schema.
• B. You expect the source schema to be identical every time and want it mirrored in the destination.
• C. You anticipate a changing schema but want to customize it with an AttributeManager before writing.
• D. You want to enforce a fixed destination schema regardless of incoming data.

Answer: (A)

Automatic mode lets the writer adapt to varying input schemas by creating destination feature types on the fly. This means you can write outputs even when the fields or their presence change from run to run, without needing a fixed schema ahead of time. That’s why it’s the best fit when you don’t expect the same schema each time and want results written regardless of the exact schema. If you needed a fixed destination structure, you’d use a non-automatic mode to enforce that specific schema instead.
