[单选题]Your network includes Windows 98 computers and Windows 2000 Server computers. You are adding a new computer to the network, and you plan to install Windows 2000 Server on the new computer. The computer has one 20-GB hard disk with no partitions defined.The Windows 2000 Server CD-ROM is unavailable. You want install Windows 2000 Server from source files that are located on a server on the network. You also want the entire hard disk of the new computer to be used for the system partition.

正确答案 ：E

Start the new computer by using a Windows 98 network boot disk. Create and format a single FAT32 partition. Connect to the network server. Run Winnt.exe.

解析：解析：Explanation: To install Windows 2000 Server on computers from source files that are located on a centralized network share we would have to connect to the network share from the the computers. If the computers do not have PXE-compliant network cards we would have to make a network boot disk that the computers can use connect to the network share. We would start the installation process by using winnt with /s /u /udf switches. We must use winnt and not winnt32 as the boot disks operate in DOS mode, which works with 16-bit applications. We would thus not be able to use 32-bit applications like winnt32.

[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.
