What action should you take in the Copy data activity to meet schema requirements for external data?

In the context of the Copy data activity, selecting the Table action to Overwrite is essential for meeting schema requirements when working with external data. This action ensures that the destination table is replaced entirely with the data being copied. If the existing data structure differs from the external data, overwriting the table enables the current schema to align with the expected format of the external data.

When this option is chosen, the existing schema is discarded, and the new schema based on the external data's structure is created. This option is particularly useful when you want to ensure that the destination matches the source in terms of structure, minimizing the risk of schema mismatch issues.

The other options do not directly address the need to conform the schema to that of the external data effectively. For instance, adding additional columns in the Source tab does not guarantee alignment with the destination schema. Enabling staging may improve performance but does not directly resolve schema consistency. Finally, using Recursively in the Source tab might pertain to data handling strategy rather than directly aligning schemas.
