One computer is running Internet Information Services (IIS), and the other is running SQL Server 2000. Company partners need to connect by means of the Inter

21、net and query data stored on the SQL Server computer. Some of these partners have computers that do not use Microsoft operating systems or Web browsers. You need to configure the IIS and SQL Server 2000 computers to allow access to data by means of the IIS virtual directory. IIS uses Basic Authentic

22、ation to allow access to the virtual directory. Only company partners should have access to the SQL Server computer by means of the Internet.

Place the table in the PRIMARY filegroup. F. Place the table in a new filegroup named LOCATION. 9 You are the administrator of

29、 several SQL Server 2000 computers. You configure these servers to send e-mail messages to SQL Server operators whenever a SQL server agent job fails or encounters an error. Your companys software developers create a set of stored procedures that send query results in email messages about stored pro

30、cedures that have not been successful. By using a MAPI profile named MS Exchange Settings, you verify that SQLAgentMail is correctly configured and working properly. You need to configure the servers so that the stored procedures function correctly. Which two actions should you take? (Each correct a

33、rofile. 微软认证 70-228模拟试卷 4答案与解析 1 【正确答案】 A 【试题解析】 Explanation: SQL Server 2000 allows filegroups other than the primary filegroup to be marked as readonly. A filegroup that is marked read-only cannot be modified. Tables that must not be modified can be placed on a filegroup that can then be mark as r

34、ead-only. This will prevents accidental updates. Incorrect Answers: B: This solution effectively permits all users to modify any table in the database, as they would all have SELECT permissions to the database. C: This solution will effectively prevent all users from being able to performing these t

35、asks on all tables in the database as they are denied permissions to run INSERT, UPDATE, or DELETE statements against the database. A better solution would be to apply the deny permissions at the table level of the lookup tables. This would, however, require unnecessary administrative time. D: Views

36、 are virtual tables that are used to filter tables or rows that the users should not have access to, however, if the users have access to the base tables, they can still run INSERT, UPDATE, and DELETE statements against the base table. 2 【正确答案】 A 【试题解析】 Explanation: Triggers are a special class of s

37、tored procedure defined to fire automatically when an UPDATE, INSERT, or DELETE statement is issued against a table or view. They are powerful tools that can be used to enforce business rules automatically when data is modified. Triggers can extend the integrity checking logic of SQL Server constrai

38、nts, defaults, and rules, although constraints and defaults should be used instead whenever they provide all the needed functionality. In this scenario an AFTER UPDATE trigger can be used to update the tables to update the PartsShipped and the PartsReceived tables that update the InStock column in t

39、he parts table. Incorrect Answers: B: A user-defined function is a subroutine that is made up of one or more Transact-SQL statements and can be used to encapsulate code for reuse. It can be used to run aggregate calculations. However, a simple update of the InStock column, and not a aggregate functi

40、on, is required when changes are made to the PartsShipped and PartsReceived tables. This can be accomplished through the use of triggers. C: A view would not be able to detect changes in any of the columns. Note: A view is a virtual table that allows data to be accessible through it rather than thro

41、ugh the base table. A view can be referenced through Transact-SQL statements in the same way a table is. In addition a table can be used to restrict a user to specific rows and/or columns in a table, join columns from multiple tables so that they appear as a single virtual table and can aggregate in

42、formation instead of supplying details to the user. D: A simple update of the InStock column, and not a stored procedure, is required when changes are made to the PartsShipped and PartsReceived tables. This can be accomplished through the use of triggers. Note: A stored procedure is a group of Trans

43、act-SQL statements compiled into a single execution plan. Stored procedures can return data as output parameters; return codes; a result set for each SELECT statement contained in the stored procedure or any other stored procedures called by the stored procedure; or a global cursor that can be refer

44、enced outside the stored procedure. Stored procedures assist in achieving a consistent implementation of logic across applications and can improve performance. 3 【正确答案】 B 【试题解析】 Explanation: With SQL Server 2000 it is possible to create tables or indexes on specific filegroups. This allows us to con

45、trol where the databases tables and indexes are physically located as filegroups can be placed on different hard drives. Placing heavily accessed tables in one filegroup and the tables nonclustered indexes in another filegroup on different physical disk can improve database performance because it wi

46、ll allow separate threads to access the tables and indexes. However, a table and its clustered index cannot be separated into different filegroups as the clustered index determines the physical order of the data in the table. Incorrect Answers: A, C, D: With SQL Server 2000, placing the tables and t

47、heir nonclustered indexes in different filegroups that are located on different physical drives provides better performance than placing tables in different filegroups and on different physical drives. 4 【正确答案】 B 【试题解析】 Explanation: The Bulk Insert Task is the fastest mechanism for copying large amo

48、unts of data into a SQL Server 2000 table or view. However, transformations cannot be performed on the data while it is moved from the source file to the table or view, as this would slow down the data copy process. Thus the text file must be formatted before the Bulk Insert Task is used. The format

49、 file provides the default information used either to bulk copy the data in the data file into an instance of SQL Server 2000 or to bulk copy data out from the table. The format file also provides a way to bulk copy data selectively from a data file to an instance of SQL Server. This allows for the transfer of data to a table when there is a mismatch between fields in the data file and columns in the table. By using a format file, it is possible to bulk copy data into an instance of SQL Server without having to add or delete unnecessary data, or reorder existing data, in the data file. Inco
