[单选题]You want to install Windows 2000 Professional on 30 PXE-compliant computers and 35 non-PXE-compliant computers. All 65 computers are included on the current hardware compatibility list (HCL). You create a RIS image. You load the image on the RIS server. You then start the 65 computers.You find that the 30 PXE-Compliant computers can connect to the RIS server.

正确答案 ：B

Run Rbfg.exe to create a Non-PXE-compliant startup disk.

解析：解析：Explanation: Non-PXE compliant clients need to use a network boot disk to be able to connect to the RIS server. This boot disk can be created using the RBFG.EXE utility (remote boot floppy generator).

[单选题]You are the administrator of a SQL Server 2000 computer. The server contains a database that stores financial data. You want to use Data Transformation Services packages to import numeric data from other SQL server computers. The precision and scale values of this data are not defined consistently on the other servers.You want to prevent any loss of data during the import operations. What should you do?

正确答案 ：B

Use the ALTER COLUMN clause of the ALTER TABLE statement to change data types in the destination tables. Change the data types to reflect the highest precision and scale values involved in data transfer.

解析：解析：Explanation: The ALTER COLUMN clause of the ALTER TABLE statement can be used to change the definition of a column and can be used to alter the precision and scale values of the data types. The destination precision should be changed so no data would be lost. The transformation to a data type with higher precision is automatic and would not require any coding.

[单选题]You are the administrator of two Microsoft Windows 2000 advanced server computers. On these servers, you are configuring a database that will store accounting information for your company.The data must be available at all times. Interruptions in data connectivity should not last longer than five minutes. Any changes to the database should not require you to reconfigure the client computers.

正确答案 ：B

Configure the database on the two servers as a SQL Server 2000 cluster.

解析：解析：Explanation: SQL Server 2000 failover clustering provides high availability support by allowing us to configure one failover cluster to automatically, with no manual configuration, fail over to any other node in the failover cluster configuration. In this way, we minimize system downtime and provide high server availability during an operating system failure or a planned upgrade. Before SQL Server 2000 failover clustering can be set up, we must install Windows NT 4.0, Enterprise Edition, Windows 2000 Advanced Server or Windows 2000 Datacenter Server, and the Microsoft Cluster Service (MSCS).
