Copying an attribute creates a duplicate and preserves the original.

• A. It replaces the original
• B. Not sure
• C. True
• D. False

Answer: (C)

Copying an attribute creates a duplicate by assigning the same value to a new attribute name while leaving the original attribute intact. This non-destructive behavior is key: you can use the copy for downstream processing, calculations, or formatting without losing the original data. For example, you might copy a value from an attribute like "length" into a new attribute "length_feet" to perform unit conversions, and the original "length" remains available for other uses. In FME, this is typically done by creating a new attribute and setting its value to the existing attribute’s value; the original attribute is preserved unless you explicitly rename or delete it. So, the statement is true: copying indeed creates a duplicate and preserves the original.
