問題

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.

參考答案
正確答案:BCE
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.

  • Exhibit:

    BULK INSERT Ezonexam.dbo.employees

    FROM ‘tk\africe\fubar512.txt’

    WITH DATAFILETYPE = ‘char’,

    FIELD/TERMINATOR = ‘\t’,

    ROWTERMINATOR = ‘\n,’

    TABLOCK

    You work as database administrator at Ezonexam.com. You handle one SQL Server 2000 computer.

    How should you improve the performance of the query in the exhibit above?

    A. Extend the BULK INSERT statement with the BATCHSIZE option set it to equal to 5 percent of the number of rows to be loaded.

    B. Extend the BULK INSERT statement with the BATCHSIZE option set it to equal to 10 percent of the number of rows to be loaded.

    C. Extend the BULK INSERT statement with the ROWS_PER_BATCH option set it to equal to 5 percent of the number of rows to be loaded.

    D. Extend the BULK INSERT statement with the ROWS_PER_BATCH option set it to equal to 10 percent of the number of rows to be loaded.

    E. Insert a line before the BULK INSERT statement that drops the indexes for the customers table. Insert a line after the BULK INSERT statement that recreates the indexes for the customers table.

    F. The TABLOCK option should be removed.

    G. The ROWTERMINATOR line should be removed.

  • 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.
