You are the administrator of a SQL Server 2000 computer. You create a Data Transformation Services (DTS) package. The package is stored as a local package on the server. The package exports data from an online transaction processing (OLTP) database system to an online analytical processing (OLAP) database system that is located on a second SQL Server 2000 computer.You want the package to execute automatically each evening at 8:00 P.M. What should you do?A．Use SQL Server Enterprise Manager to create a new job Create a CmdExec job step that runs the dtsrun utility Schedule the job to run each night at 8:00 P.M.B．Use SQL Server Enterprise Manager to create a new job Create a Transact-SQL job step to query data from the OLTP database Create a second Transact-SQL job step to launch the DTS package Schedule the job to run each night at 8:00 P.M.C．Create a batch file that runs the dtsrun utility Use the Microsoft Windows Task Scheduler to run the job each night at 8:00 P.M. Configure the Windows Task Scheduler to use the local system accountD．Move the DTS package to the repository Configure the SQLServerAgent service on the OLAP database server to update the package each night at 8:00 P.M.

As an administrator at Cer-tech .com， you manage a member server having Windows Server 2008. A Terminal Services role is installed on the server along with Microsoft Windows System Resource Manager（WSERVERM）. Users are complaining about degradation in performance on Terminal Server. You find outthat a single user is consuming 100% of the processor time. To rectify the problem， you create a resource-allocation policy named Policy1 which limits each user to 30% of the total processor time. Still， there is noimprovement in the performance. What should you do to configure WSERVERM to force Policy1？（）A、Configure each user account to allocate a resource quota on WSERVERM applicationB、Configure Policy1 to accept the WSERVERM resource quota for each userC、Restart the Server and the Terminal Services configuration serviceD、Configure policy1 as the Managing Policy
考题
When a system has both online transaction processing as well as large batch processing， which of the following common procedures will best help to improve system performance？（）A、 Boost the priority of batch jobs.B、 Schedule batch runs to reduce contention with OLTP.C、 Schedule OS maintenance such that it includes frequent application of PTFs.D、 Perform incremental backups of transaction processing and full backups of batch processing.
考题
You recently activated a resource plan named OLTP_PLAN in your database. Several users are concurrently running long transactions.
