第6题：
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.
解析：Explanation:
A: Bulk update locks are taken when bulk copying data into a table and either the TABLOCK hint is specified, or the table lock on bulk load table option is set using sp_tableoption. Bulk update locks allow processes to bulk copy data concurrently into the same table while preventing other processes that are not bulk copying data from accessing the table. In this scenario the bulk update lock would meet the requirement that data should be loaded as quickly as possible.
B: SQL Server 2000 allows data to be bulk copied into a single table from multiple clients in parallel using the bcp utility or BULK INSERT statement. This can improve the performance of data load operations. To bulk copy data into an instance of SQL Server in parallel, the database must be set to Bulk-Logged Recovery, the TABLOCK hint must be specified, and the table must not have any indexes.
E: By specifying the Bulk-Logged Recovery model, the logging for all SELECT INTO, CREATE INDEX, and bulk loading data operations will be minimal and will therefore require less log space while also improving performance.
Incorrect Answers:
C: When data is bulk copied into a single table from multiple clients in parallel using the bcp utility or BULK INSERT statement to improve the performance of data load operations, the database must be set to Bulk-Logged Recovery, the TABLOCK hint must be specified, and the table must not have any indexes.
D: When data is bulk copied into a single table from multiple clients in parallel using the bcp utility or BULK INSERT statement to improve the performance of data load operations, the database must be set to Bulk-Logged Recovery, the TABLOCK hint must be specified, and the table must not have any indexes.

You are using flat files as the data source for one of your data warehousing applications. To optimize the application performance， you plan to move the data from the flat files to clustered tables in an Oracle database.While migrating the data， you want to have minimal impact on the database performance and optimize the dataload operation. Which method would you use to load data into the Oracle database（）
- A、Use the external table population.
- B、Use the Oracle Data Pump export and import utility.
- C、Use the conventional path data load of the SQL*Loader utility.
- D、Use the INSERT INTO...SELECT command to load the data
正确答案:C

第10题：
In which two scenarios do you use SQL* Loader to load data?（）
