Microsoft PRO:MS SQL Serv 08,Design,Optimize, and Maintain DB Admin Solu 認定 070-450 試験問題:

1. You are a professional level SQL Sever 2008 Database Administrator.
The solution is log-shipped for high-availability purposes. The data files of the database reside on drive D,
while the transaction log files of the database reside on drive E. A restoring test plan should be
implemented
to satisfy the requirements listed below for the log-shipping solution.
First, the secondary database is brought online in the shortest time.
Secondly, the data is in a consistent state.
Thirdly, the data loss is reduced to the least.
The first step for the recovery test plan should be identified in the event of drive D failure.
Which step should be performed?

A) You should execute the DBCC CHECKDB command along with the REPAIR_REBUILD option against the primary database.
B) You should perform the tail-log backup of the primary database.
C) You should execute the DBCC CHECKDB command along with the REPAIR_ALLOW_DATA_LOSS option against the primary database.
D) You should bring the secondary database online.

2. You are a professional level SQL Sever 2008 Database Administrator.
A database is included by an instance. And a large table named OrderDetails is included by the database. Only DML statements on the last three months data are executed by the application queries. Administrative audits are managed monthly on data which is longer than four months. The performance problems listed below are found by you in the database . The performance of the application queries against the OrderDetail table is poor. It takes a long time to perform the maintenance tasks against the database, index defragmentation is contained.
The performance problems should be solved with on impact on the server performance.
Which action will you perform?

A) An additional table named OrderDetailsHistory should be created for data older than four months. And then, the OrderDetails and OrderDetailsHistory tables should be partitioned in two parts by utilizing the OrderDate column. At last, a SQL Server Agent job that runs every month should be created and the ALTER TABLE...SWITCH Transact-SQL statement should be utilized to remove data that is longer than four months to the OrderDetailsHistory table.
B) An additional table named OrderDetailsHistory should be created for data longer than four months. And then, a SQL Server Agent job that runs the following Transact-SQL statement every month should be created. INSERT INTO OrderDetailsHistory SELECT * FROM OrderDetailsWHERE DATEDIFF(m, OrderDate,GETDATE())>4
C) An additional table named OrderDetailsHistory should be created for data older than four months. And then, the following Transact-SQL statement should be utilized. CREATE TRIGGER trgMoveDataON OrderDetailsAFTER INSERT ASINSERT INTO OrderDetailsHistory SELECT * FROM OrderDetailsWHERE DATEDIFF(m,OrderDate,GETDATE())>4
D) A database snapshot should be created for the OrderDetails table every four months. And then, the queries should be changed to utilize the present snapshot.

3. You are a professional level SQL Sever 2008 Database Administrator.
The largest table in a database is partitioned into four equal-sized parts.
The first two partitions are seldom queried, while the third partition is regularly queried by several reports. Meanwhile, the fourth partition is heavily queried and regularly modified.
The disk space of the table should be cut to the least and the query performance should be with the least impact.
What will you do? (Choose more than one.)

A) PAGE compression should be enabled for the third partition.
B) PAGE compression should be enabled for the first two partitions.
C) ROW compression should be enabled for the third partition.
D) ROW compression should be enabled for the first two partitions.
E) PAGE compression should be enabled for the last partition.
F) ROW compression should be enabled for the last partition.

4. You administer a SQL Server 2008 infrastructure. You plan to design an infrastructure for a new application.
The application has the following requirements:
Users can connect to an instance named SQLSERVER1.
SQLSERVER1 is linked to a server named SQLSERVER2.
SQLSERVER1 and SQLSERVER2 run on different computers.
The SQL Server instances use only Windows authentication.
You need to configure the infrastructure to ensure that the distributed queries are executed in the Windows security context of the login.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

A) Configure all servers to use the Shared Memory network protocol.
B) Create a map for each SQL login from SQLSERVER1 to SQLSERVER2 and use the impersonate option.
C) Use the local computer account as a service account for SQLSERVER1 and SQLSERVER2.
D) Ensure that the two instances use the same Windows account for the Microsoft SQL Service. Create the link so that each account uses the current security context.
E) Register a server principal name (SPN) for SQLSERVER1 and SQLSERVER2.

5. You are a professional level SQL Sever 2008 Database Administrator.
A database is hosted by the instance and the database is configured by utilizing high-safety mirroring operation mode along with a witness server. A memory failure is experienced by the witness server; therefore the server will be offline for five hours. The mirroring strategy should be reset to cut the risk of database unavailability to the least level.
Which action should you perform to finish the task?

A) To finish the task, database mirroring should be removed.
B) To finish the task, asynchronous operating mode should be utilized.
C) To finish the task, database mirroring should be paused.
D) To finish the task, the witness server should be moved from the mirroring session.
