[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 Ezonexam's network. You want to deploy a Windows 2000 Professional service pack to 10 computers in the Development organizational unit.You create a Windows 2000 installer package file for the service pack. You use the package file to successfully install the service pack to other computers in the domain. You assign the package file to the Development organizational unit. After the installation, you notice that the service pack was not installed on any of the 10 computers.

正确答案 ：E

Add the user accounts from the Development organizational unit to a DACL. Grant the user accounts read permission to the service pack deployment directory.

解析：解析：Explanation: Before users can access resources on Windows 2000, they must be assigned the appropriate permissions to those resources. In this scenario the users from the Development OU need to be assigned read permission to the deployment directory, which is an object, to be able to start the installation process. Objects, such as the deployment directory, use a DACL (discretionary access control list) to check whether users or groups have been allowed or denied permissions to the object that they are attempting to access. Therefore, the user accounts of the Development OU must be added to the DACL of the deployment folder.
