Which statement about extending an existing table is false?

• A. The new table inherits the functionality built into the parent table
• B. The extension can add new fields
• C. The extension cannot change the existing data model
• D. The extension applies within its own scope

Answer: (A)

When you extend a table, you create a child table that shares the parent’s structure and can add its own fields. You can’t change the parent’s existing data model from the child, and the extension sits within its own application scope. While the child inherits much of the parent’s behavior, not every piece of functionality is automatically carried over—some UI policies, client scripts, or business rules may need to be recreated or adjusted for the child to behave the same way. So the statement about inheriting all functionality built into the parent isn’t entirely accurate. The extension can add new fields, cannot alter the parent’s existing data model, and applies within its own scope.
