What is the advantage of using schema features in this scenario?

• A. All features automatically have schema list attributes, so you don't have to use any special configurations to benefit from them.
• B. Schema features result in much faster writing than using external tables to define schema.
• C. You don't have to map the old schema onto the new schema in order for FME to write attribute values.
• D. You can update the external Excel table to automatically update the destination schema.

Answer: (C)

Schema features let you define the target structure you want to write to, separate from the input’s structure. In this scenario the big benefit is that you don’t have to manually map every old attribute to a new one for FME to populate the values. By describing the destination schema with a schema feature, FME knows which fields to fill and how, so attribute values flow into the correct destination attributes even if the input and output schemas don’t align perfectly. This reduces the need for explicit per-field mappings and makes adapting to schema changes easier. The other options aren’t the main purpose here: this feature isn’t about automatic performance gains, speeding up writing versus external tables, or automatically updating an external Excel table.
