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.
A SQL Server 2008 instance at the New York central site is managed by you, and it is called Ins01.
There is a sales team in your company, and their task is to finish purchase orders for customer requests.
The sales team updates data regularly in a local database by utilizing their portable computers.
When the central site is connected by portable computers, a database named Sales will be synchronized
with
the local database. A duplication model will be created to duplicate the local database to the Sales
database.
The requirements listed below should be satisfied by the duplication model:
First, when the same data is updated by multiple users independently, there should be no data conflicts.
Secondly, sensitive data such as product price cannot be updated by the sales team.
Thirdly, the data should be synchronized by the sales team not only at scheduled times but also on demand.
The best model should be identified to have data duplicated, and you should be reduced the development efforts to the least.
Which action will you perform?
A) You should utilize snapshot duplication along with each portable computer that is set up as a subscriber.
B) You should utilize SQL Server Integration Services (SSIS) to promote the date modification and pull updates to the Sales database along with the SSIS packages, on demand.
C) You should utilize transactional duplication along with each portable computer that is set up as a publisher.
D) You should utilize merge duplication along with each portable computer that is set up as a subscriber.
2. You are designing the storage scheme for a new SQL Server 2008 database application
The application will primarily be used to query data.
The database will be initially populated with 4 terabytes of data stored in 20 tables.
The data is distributed evenly throughout all 20 tables. Every night, between 100 GB and 300 GB of new
data will be loaded into 4 database tables.
The remaining 16 tables will remain static. The average CPU utilization of the server where the
application will reside is between 30 and 50 percent.
You need to ensure that the amount of disk space used is reduced.
You need to achieve this goal by ensuring minimum impact of performance on the server.
What should you do? (More than one answer choice may achieve the goal. Select the BEST answer.)
A) Use row-level data compression on the 16 tables that remain static.
B) Use page-level data compression on the 16 tables that remain static.
C) Use page-level data compression on the 4 tables that are loaded every night.
D) Use row-level data compression on the 4 tables that are loaded every night.
3. 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, asynchronous operating mode should be utilized.
B) To finish the task, the witness server should be moved from the mirroring session.
C) To finish the task, database mirroring should be paused.
D) To finish the task, database mirroring should be removed.
4. You are a professional level SQL Sever 2008 Database Administrator.
There are 30 branch offices in DoubleSecurity Insurance, and in the branch offices, customer data are stored in SQL Server 2008 databases. Customer data should be security compliant if it is stored through multiple database instances.
You intend to utilize the Policy-Based Management feature to design a strategy for custom policies. And the format of custom policies is XML format. The requirements listed below should be satisfied.
The company distributes custom policies to all instances. In addition, the company enforces the policies on all instances. A strategy should be thought out and the minimum amount of administrative effort should be utilized.
Which action should you perform to finish the task?
A) To finish the task, the policies should be distributed by utilizing the Active Directory directory service.
B) To finish the task, the policies should be distributed by utilizing Group Policy Objects.
C) To finish the task, a configuration server should be utilized.
D) To finish the task, the Distributed File System Replication service should be utilized.
5. 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 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
B) 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.
C) 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.
D) 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
