What is a consequence of a dynamic schema change that does not include a proper mapping for incoming features?

• A. No output is produced
• B. Attribute values may be absent or misaligned
• C. Output is written with defaults
• D. System crashes

Answer: (B)

When a dynamic schema change happens but there isn’t a proper mapping for the incoming features, the system can’t correctly place incoming attribute data into the new or altered fields. That means some attribute values end up missing (absent) and others may land in the wrong fields (misaligned). In practice, you’ll see nulls or data in the wrong columns rather than a cleanly populated dataset. The other outcomes—no output, defaults being written, or a system crash—aren’t the typical result unless there are additional configurations or errors: missing mapping simply leads to misplacement or null values in the attributes rather than stopping processing or forcing defaults.
