You want to schedule a job to rebuild all indexes on the SALES table after the completion of a bulk load operation.  The bulk load operation must also be a scheduled job that executes as soon as the first file that contains data arrives on the system.  How would you create these jobs？（）

• A、 Create both jobs by using events raised by the scheduler
• B、 Create both jobs by using events raised by the application
• C、 Create a job to rebuild indexes by using events arised by the application and then create another job to perform bulk load by using events raised by the scheduler
• D、 Create a job to rebuild indexes by using events arised by the Scheduller and then create another job to perform bulk load by using events raised by the application
