What must be done to group multiple SQL commands within a TransactionScope?

1. Call the BeginTransaction method

2. Execute the commands directly

3. Ensure scope.Complete() is called after commands

4. Use the using statement exclusively

The correct answer is: Ensure scope.Complete() is called after commands

To group multiple SQL commands within a TransactionScope effectively, it is crucial to ensure that `scope.Complete()` is called after executing those commands. This method signals that all operations within the transaction were successful and that the transaction can be committed. When you create a TransactionScope, you're essentially beginning a transaction that encompasses all operations performed within that scope. If everything operates correctly and you want the changes to be preserved, invoking `scope.Complete()` is necessary. It acts as a confirmation that you are satisfied with the outcome of the transaction. If this line is not executed, the transaction will be rolled back when the scope is disposed, meaning none of the operations will take effect. Other methods of handling transactions like calling a BeginTransaction method or executing commands directly do not achieve the same goal of managing transaction completion through the TransactionScope framework. Likewise, while using the using statement is a good practice for resource management, it doesn't automatically ensure the transaction's successful completion unless `scope.Complete()` is included. Therefore, ensuring that `scope.Complete()` is called is the correct action to finalize the intentions of the transaction successfully.
