D、 Configure the DTS package to include an on failure precedence constraint and a send mail task. Configure the execute process task to execute a not send command that will notify you if the package fails.

【正确答案】 B

【答案解析】解析：Explanation: When jobs are completed (successfully or not), the subsystem returns a result status (with optional messages) to SQL Server Agent. SQL Server Agent then records the completion status in both the operating system's application log and the job history table in SQL Server and optionally sends an e-mail report or an SQL Server event alert of the job status to the designated operator. Incorrect Answers: A: We are interested to when the package has completed. The completion status, not the log package execution, should be used to trap the completion of a package. The execution status concerns Last run time, Last run status, Last run message, etc. C, D: The Messaging Application Programming Interface (MAPI) isn't installed. MAPI is needed for SQL Server to send e-mail. No e-mail can be send by SQL Server in this scenario.
