题目
You are the administrator of a SQL Server 2000 computer. The server is configured as shown in the Database Server Configuration exhibit.
You need to create a new database named Inventory. Employees in your company will use the Inventory database to track inventory data. Users will require immediate responses to queries that help them locate where parts are stored. The tables in the database will be configured as shown in the Database Schema exhibit.
The database will consume 14 GB of disk space. You must configure the data files and transaction log to accelerate query response time.
Which two courses of action should you take? (Each correct answer represents part of the solution. Choose two.)
A. On drive C, create a transaction log.
On drive D, create a data file in the PRIMARY filegroup.
On drive E, create a data file in the SECONDARY filegroup.
B. On each drive, create a transaction log.
On each drive, create a data file in the PRIMARY filegroup.
C. On drive D, create a transaction log.
On drive E, create a data file in the PRIMARY filegroup.
D. On the PRIMARY filegroup, create all tables and all indexes.
E. On the PRIMARY filegroup, create all tables. On the SECONDARY filegroup, create all indexes.
F. On the PRIMARY filegroup, create the Parts table and its indexes.
On the SECONDARY filegroup, create all other tables and their indexes.
参考答案和解析
A,E 解析：Explanation:
A: The transaction log should be placed on a separate disk. A transaction log would not benefit of two or more disks since it is sequential. Create two data files on two separate physical disks would improve performance.
E: Separating the tables and the indexes improve performance for in particular joins.
Note: With SQL Server 2000 it is possible to create tables or indexes on specific filegroups. This allows us to control where the database's tables and indexes are physically located as filegroups can be placed on different hard drives. Placing tables in one filegroup and the table's nonclustered indexes in another filegroup on different physical disk can improve database performance because it will allow separate threads to access the tables and indexes.
However, a table and its clustered index cannot be separated into different filegroups as the clustered index determines the physical order of the data in the table. Furthermore, the transaction log should be placed on a physically separate disk. The transaction log file is written serially; therefore, using a separate, dedicated disk allows the disk heads to stay in place for the next write operation. This will further improve performance.
Incorrect Answers:
B: To improve performance, the transaction log should not be placed on the same physical disk that the tables or indexes are placed on. The transaction log file is written serially; therefore, placing it on a separate, dedicated disk allows the disk heads to stay in place for the next write operation and thus improves performance.
Furthermore, placing tables in one filegroup and the table's nonclustered indexes in another filegroup on different physical disk can improve database performance because it will allow separate threads to access the tables and indexes. However, a table and its clustered index cannot be separated into different filegroups as the clustered index determines the physical order of the data in the table.
C: The transaction log should be placed on a physically separate disk. The transaction log file is written serially; therefore, using a separate, dedicated disk allows the disk heads to stay in place for the next write operation. This will further improve performance. In this solution, the tables and their indexes are placed on the same disk. This solution thus does not take advantage of the performance improvements that can be realised through the correct utlization of the available hardware.
D: In this solution, the tables and their indexes are placed on the same disk. This solution thus does not take advantage of the performance improvements that can be realised through the correct utlization of the available hardware.
F: Greater performance gains can be realized by placing tables in one filegroup and the table’s nonclustered indexes in another filegroup on different physical disk. This will allow separate threads to access the tables and indexes.

第1题：
You are the administrator of a SQL Server 2000 computer. Your company uses the server to store service contract information for its customers.
You are also the administrator of Oracle relational database management system (RDBMS) server.
This server is used to store your company’s financial information. The financial information is updated frequently throughout the day.
You need to create a series of reports that combine the service contract information and the financial information. These reports will be updated several times a day.
You want to create reports on the SQL Server computer by using the minimum amount of disk space.
What should you do?
A．Set up SQL server replication to replicate the data from the oracle server to the SQL server computer.
B．Set up the oracle server as a linked server. Create a view that joins the service contract information and the financial information.
C．Set up data transformation services (DTS) package that imports and transforms the database from the oracle server to the SQL server computer. Use SQL server agent to execute the DTS package throughout the day as needed.
D．Set up Microsoft ActiveX script. that connects to the oracle server and imports the financial information into SQL server temporary table. Create a view that joins the service contract information and the temporary table.
解析：Explanation: SQL Server 2000 permits the creation of links to OLE DB data sources called linked servers. After linking to an OLE DB data source, it is possible to reference rowsets from the OLE DB data sources as tables in Transact-SQL statements and to pass commands to the OLE DB data sources and include the resulting rowsets as tables in Transact-SQL statements.
Each distributed query can reference multiple linked servers and can perform. either update or read operations against each individual linked server. A single distributed query can perform. read operations against some linked servers and update operations against other linked servers. The Microsoft OLE DB Provider for Oracle allows distributed queries to query data in Oracle databases.
Incorrect Answers:
A: Replication allows for the coping, distribution, and modification of data across an enterprise. This involves the copying of database data from one server to another. This is not the best solution in this scenario as this will require frequent replication because the reports must be updated several times a day.
C: Data Transformation Services is a set of graphical tools and programmable objects that allows for the extraction, transformation, and consolidation of data from disparate sources into single or multiple destinations. In this scenario, however, the Oracle database needs to be included in a query. Hence, Data Transformation Services are inappropriate.
D: Microsoft ActiveX scripts can be used to add functionality to Data Transformation Services packages, which is a set of graphical tools and programmable objects that allows for the extraction, transformation, and consolidation of data from disparate sources into single or multiple destinations. In this scenario, however, the Oracle database needs to be included in a query. Hence, Data Transformation Services are inappropriate.
第2题：
You are the administrator of Microsoft Windows 2000 computer. You are preparing to install SQL Server 2000 on the computer.
Your company contains a variety of client computers that will connect to the SQL server 2000 computer by using a specific Net-Library, as shown in the following table.
You need to allow the client computers to connect to the SQL Server 2000 computer. You also want to minimize the number of configuration changes required on the client computers.
Which three actions should you take? (Each correct answer presents part of the solution. Choose three)
A. Install SQL Server 2000 as a named instance.
B. Install SQL Server 2000 as the default instance.
C. Configure the new instance for Mixed Mode Authentication.
D. Configure the new instance for Windows Authentication.
E. Configure the server to use the Named Pipes, IPX/SPX, and TCP/IP Net-Libraries.
F. Configure the server to use the Multiprotocol Net-Library.
B,C,E 解析：Explanation:
B: We need to use a default instance of SQL Server in order to allow all the different clients to connect.
C: The client computers in this scenario will be running Windows 98, Novel NetWare and Apple Macintosh. SQL Server Authentication is required as these operating systems are not supported by Windows Authentication, however, the use of SQL Server Authentication is offered only for backward compatibility, hence we need to implement Mixed Mode Authentication.
E: By using specific communication protocols, and not the Multiprotocol Net-Library, performance would be better. Every extraneous protocol adds overhead.
Note: Configuring Net-Libraries has been simplified for applications using the SQL Server 2000 client connectivity components. Selecting the client protocols to be installed on the application computer must be done during setup, and selecting the server protocols to be enabled on the instance of SQL Server 2000 must be done during the SQL Server 2000 setup. No other configuration is required. Once setup, a client can connect to any instance of SQL Server 2000 by specifying the network name of the database computer and the instance name.
Note: SQL Server 2000 can operate in either Windows Authentication mode, which allows a user to connect through a Windows NT 4.0 or Windows 2000 user account; Mixed mode, which allows users to connect to an instance of SQL Server 2000 by using either Windows Authentication or SQL Server Authentication.
Furthermore, users who connect through a Windows NT 4.0 or Windows 2000 user account can make use of trusted connections in either Windows Authentication mode or Mixed mode. When a user connects to SQL Server 2000 with a nontrusted connection, SQL Server 2000 performs the authentication itself by checking if a SQL Server login account has been created and if the supplied password is correct. SQL Server Authentication is also used for backward compatibility because applications written for SQL Server 7.0 or earlier may require the use of SQL Server logins and passwords. In addition, SQL Server Authentication is required when an instance of SQL Server is running on Windows 98 because Windows Authentication mode is not supported on Windows 98.
Incorrect Answers:
A: The Multiprotocol Net-Library can only be used to connect to a default instance of SQL Server 2000 as it does not support named instances of SQL Server 2000 or server enumeration.
D: As client computers will be running Windows 98, Novel NetWare and Apple Macintosh, we cannot use Windows Authentication as these operating systems are not supported by Windows Authentication.
Note: Windows Authentication mode allows a user to connect through a Windows NT 4.0 or Windows 2000 user account and makes use of trusted connections. When a user connects to SQL Server 2000 a nontrusted connection, SQL Server 2000 performs the authentication itself by checking if a SQL Server login account has been created and if the supplied password is correct. Mixed mode allows users to connect to an instance of SQL Server 2000 by using either Windows Authentication or SQL Server Authentication.
F: The Multiprotocol Net-Library is used to support the different protocol that the clients use. This provides easy of administration. However, since unused protocols are installed, it also introduces overhead. This is not the best solution.
Note: The Multiprotocol Net-Library allows for the automatic selection of available network protocols to communicate with an instance of SQL Server 2000. This is convenient for connecting to multiple servers running different network protocols without having to reconfigure the client connection for each server. If the client and server Net-Libraries for TCP/IP Sockets, NWLink IPX/SPX, or Named Pipes are installed on the client and server, the Multiprotocol Net-Library will automatically choose the first available network protocol to establish a connection.
The Multiprotocol Net-Library can only be used to connect to a default instance of SQL Server 2000 as it does not support named instances of SQL Server 2000 or server enumeration.

第5题：
You are the administrator of several SQL Server 2000 computers. You want to retrieve information from an archived inventory database. You have a full tape backup of the database. The backup’s header information shows that the backup uses the SQL_Latin1_General_CR437_BIN collation.
However, the existing SQL server computers in your office are configured to use the
SQL_Latin1_General_CP1_CI_AS collation.
You do not want to join tables in the inventory database with tables in other databases. You need to restore the inventory database to a SQL Server 2000 computer by using the least amount of administrative effort.
What should you do?
A．Use the rebuildm utility to rebuild the system database on an existing SQL server computer. Configure all the databases on that server to use the SQL_Latin1_General_CR437_BIN collation. Restore the inventory database to the server.
B．Restore the inventory database to an existing SQL server computer. Accept the SQL_Latin1_General_CR437_BIN collation for that database.
C．Install a new named instance of SQL Server 2000 on an existing SQL Server 2000 computer. Configure the named instance to use the SQL_Latin1_General_CR437_BIN collation. Restore the inventory database to the named instance.

第6题：
You are the administrator of a SQL Server 2000 computer. The server contains database named Sales. Users report that they cannot add new data to the database. You examine the properties of the database. The database is configured as shown in the Sales Properties exhibit.
You examine drive E. The hard disk is configured as shown in the Local Disk Properties exhibit.
You want the users to be able to add data, and you want to minimize administrative overhead. What should you do?
A．Increase the maximum file size of Sales_Data to 1,500MB.
B．Use the DBCC SHRINKDATABASE statement.
C．Set automatic file growth to 10 percent.
D．Create another data file named Sales_Data2 in a new SECONDARY filegroup.
解析：Explanation: By examining the first exhibit we see that the database has reached its maximum size of 1001 MB. The data file is located on drive E and the second exhibit shows us that there is enough free space on that disk to increase the maximum size of the data file to 1,500 MB.
Incorrect Answers:
B: DBCC SHRINKDATABASE could possibly shrink the database and new records could be added for a while, but it would just be a temporary solution.
C: The database is already set to automatic file growth, but it has reached the maximum size.
D: The primary file has reached it maximum size. A secondary filegroup would help if it was set to the default file group. New data would still be added to the primary filegroup which is at its maximum size.
