You work in a company which is named Wiikigo Corp. The company uses SQL Server 2008. You are the administrator of the company database. Now you are in charge of a SQL Server 2008 instance. The server hosts databases for several mission-critical applications. Microsoft SQL Server Management Studio executes queries and it has some effect. Now you intend to limit the effect by using the Resource Governor. You must make sure that queries initiated through SQL Server Management Studio is less than 20 percent of CPU utilization, besides this, you must make sure that queries initiated by the mission-critical applications can consume 100 percent of CPU utilization when required. So what action should you perform to achieve this goal? ()A、You should alter the default resource pool and set the MAX_CPU_PERCENT option to 80. Then assign this resource pool to the workload group used by SQL Server Management Studio. B、First, you should create a new resource pool and set the MAX_CPU_PERCENT option to 20. Then assign this resource pool to the workload group used by SQL Server Management Studio. C、You should alter the default resource pool and set the MAX_CPU_PERCENT option to 20. Then assign this resource pool to the workload group used by the mission-critical applications. D、First, you should create a new resource pool and set the MAX_CPU_PERCENT option to 80. Then assign this resource pool to the workload group used by the mission-critical applications.

You work in a company which uses SQL Server 2008. You are the administrator of the company database. Now you are in charge of a remote SQL Server 2008 instance. You notice that the application has a poor performance. On the remote SQL Server instance, you capture a workload of the remote instance to a trace table by using SQL Profiler. Now you have to use the Database Engine Tuning Advisor to analyze the workload of the remote SQL Server instance on a local SQL Server instance. So what action should you perform to achieve this goal?()A、You should recapture the workload by using the data collector.B、You should enable the XP_MSVER stored procedure on the local server.C、You should enable the XP_MSVER stored procedure on the remote serverD、You should recapture the workload to a trace file by using SQL Profiler.

You use a SQL Server 2005 database named DB1, which is located on a server named SQL1. DB1 is in use 24 hours a day, 7 days a week. A recent copy of DB1 exists on a second server named SQLtest that also runs SQL Server 2005. You detect a high number of full scans on SQL1 and conclude that additional indexes in DB1 are needed. A workload file that is suitable for Database Engine Tuning Advisor (DTA) already exists. You need to analyze the workload file by using DTA. You must ensure maximum performance on SQL1 during analysis. You must also ensure availability during the implementation of any recommendations suggested by the DTA. What should you do?()A、Store the workload file on SQL1. Start DTA on SQLtest and connect to SQL1. Specify all workload and tuning options as necessary. In the Advanced Tuning Options dialog box, select the Generate only online recommendations check box.B、Store the workload file on SQLtest. Start DTA on SQLtest and connect to SQLtest. Specify all workload and tuning options as necessary. In the Advanced Tuning Options dialog box,select the generate only online recommendations check box.C、Store the workload file on SQL1. Start DTA on SQL1 and connect to SQL1. Specify all workload and tuning options as necessary. In the Advanced Tuning Options dialog box,select the All recommendations are offline check box.D、Store the workload file on SQLtest. Start DTA on SQLtest and connect to SQLtest.Specify all workload and tuning options as necessary.In the Advanced Tuning Options dialog box,select the All recommendations are offline check box.
