[单选题]You are a database administrator in the Los Angeles branch office of a specialty foods supplier. A mainframe. database at the headquarters contains all company data. Each branch office contains a SQL Server 2000 computer that imports regional data from the mainframe. database.The server in Los Angeles contains a Data Transformation Services (DTS) package that uses OLE DB to connect to the company's mainframe. database. The DTS package extracts and transforms data about buyers and products for that region. The DTS package then writes the data to the SQL Server database in Los Angeles.

正确答案 ：F

On the server in Sydney, install an OLE DB provider for the mainframe. database.

解析：解析：Explanation: OLE DB is an API that allows COM applications to use data from OLE DB data sources, which includes data stored in different formats. An application uses an OLE DB provider to access an OLE DB data source. An OLE DB provider is a COM component that accepts calls to the OLE DB API and performs the necessary processing required by request against the data source. In this scenario the OLE DB source is the company's mainframe. database, which contains all company data. As each branch office contains a SQL Server 2000 computer that imports regional data from the mainframe. database, all existing and future branch office SQL Server 2000 servers will require an OLE DB provider to access the company's mainframe. database.

[多选题]You recently upgraded all Windows NT Workstation 4.0 computers to Windows 2000 Professional. You want to give a new employee named Maria the ability to back up files, share resources, and install programs on a client computer that she shares with other users. You do not want Maria to be able to read other users' files.What should you do to accomplish these goals? (Choose all that apply)

正确答案 ：CE

Add Maria's user account to the Power Users group.

Add Maria's user account to the Backup Operators group.

解析：解析：Explanation: By adding Maria's user account to the Power Users group Maria will inherit the ability to share resources and install programs on the computer. To grant Maria the ability to backup files she must be added to the Backup Operators group, which has the permissions to backup files. As a member of this group Maria will be able to backup files as she will inherit those rights by virtue of being a member of that group. Maria will not have permissions to read the users' files as neither the Power Users group nor the Backup Operators group have the permissions to read other users' files.
