[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]Ezonexam.com's network contains two domain controllers and approximately 500 client computers. The domain controllers run Windows 2000 Server. The client computers run Windows 2000 Professional. The majority of users have mobile computers. Users in Ezonexam often travel with their mobile computer for extended periods of time and do not have remote access to Ezonexam.com's network.You want to configure the domain controllers so that DNS only contains entries for computers that are active on the network. You also want to ensure that when users return you do not have to manually create or delete DNS entries.

正确答案 ：D

Configure both domain controllers with Active Directory integrated primary zones for the domain and enable scavenging and dynamic updates for the zone.

解析：解析：Explanation: Scavenging is a process whereby a DNS server periodically checks it's dynamically created records to see how long it's been since they were registered (or reregistered). Then, if the scavenger finds records that haven't been registered or reregistered in a long time, it deletes them from the zone file.

[单选题]You are the administrator of a new Microsoft Windows 2000 server computer named HQSQL5. HQSQL5 is a member server in your company's Windows NT 4.0 domain, which is named HQMAIN.After installing SQL Server 2000 on HQSQL5, you configure the MSSQLServer service account to use the HQMAIN\sqladmin user account, which is a member of the local administrators group on HQSQL5.

正确答案 ：E

Grant Log on as a service rights to the HQMAIN\sqladmin user account.

解析：解析：Explanation: On Windows NT and Windows 2000 operating systems, SQL Server 2000 and SQL Server Agent are started and run as Windows services. Windows services require ‘Log on as a service’ rights, which allow a security principal to log on as a service, as a way of establishing a security context. The Local System account on the Windows computer always retains the right to log on as a service. Any service that runs under a separate account must be granted this right.
