Answer: Use the 'dependsOn' attribute to specify both 'DataTransformation' and 'DataValidation' as predecessors.
The correct approach is to use the 'dependsOn' attribute in the job configuration to specify both 'DataTransformation' and 'DataValidation' as predecessors. This ensures that 'DataExport' will only start after both 'DataTransformation' and 'DataValidation' have successfully completed, maintaining the task dependencies.
