1.You are the administrator of a SQL Server 2000 computer. You are creating a data transformation services package. As the first step in this process, you need to load data from text files into a database table. These text files contain data on new stores that join your franchise. The text files list the data columns in the following format StoreID, StoreName, Address, City, State, PostalCode, ManagerID, StoreTypeID, FacilityID.The destination table is configured as shown in the exhibit.You want to load the data into the table as quickly as possible. What should you do?A．Use a Bulk Insert Task to read the data into a temporary table. Use an Execute SQL task to import the appropriate data into the destination table.B．Create and edit a format file to select the columns you want to import. Use a Bulk Insert Task, and then specify the format file to import the appropriate data into the destination table.C．Use a transform. data task to import the data. Use Microsoft ActiveX transformation scripts to write the appropriate data to the appropriate columns in the destination table.D．Create and edit a format file to select the columns you want to import. Use a transform. data task, and then specify the format file to import the appropriate data into the destination table.

2.You are the administrator of a new multiprocessor SQL Server 2000 computer. You are migrating data from other database management systems to this server. You need to load data from two data files into a new table on the server. The table is empty and has no indexes.You want to complete the data load as quickly as possible. What should you do? (Each correct answer represents part of the solution. Choose all that apply.)A．Apply a bulk update lock to the table.B．Use separate client connections to load the files into the table simultaneously.C．Create a clustered index on the table.D．Specify the Full Recovery model for the database.E．Specify the Bulk-Logged Recovery model for the database.

3.In which situations does the Oracle Data Pump use external tables and not the direct path load whileexporting a table（）A、if a table is not in a clusterB、if a table has an active triggerC、if a table has an encryptedD、if a table has a column of data type LONG defined on itE、if a table has a referential integrity constraint defined on it

4.You are the administrator of a SQL Server 2000 computer in your company's personnel department. Employee data is stored in a SQL Server 2000 database. A portion of the database schema is shown in the exhibit.You want to create a text file that lists these data columns in the following format title, FirstName, LastName, WorkPhone, PositionName, DepartmentName.You want to create the text file as quickly as possible. You do not expect to re-create this file, and you want to avoid creating new database objects if possible.What should you do?A．Use the bcp utility to export data from each table to a separate text file. Use format files to select the appropriate columns. Merge the data from each text file into a single text file.B．Create a view that joins data from all three tables include only the columns you want to appear in the text file. Use the bcp utility to export data from the view.C．Create a SELECT query that joins the data from the appropriate columns in the three tables. Add an INTO clause to the query to create a local temporary table. Use the bcp utility to export data from the local temporary table to a text file.D．Create a SELECT query that joins the data from the appropriate columns in the three tables. Add an INTO clause to the query to create a global temporary table. Use the bcp utility to export data from the global temporary table to a text file.
