Microsoft PRO:MS SQL Serv 08,Design,Optimize, and Maintain DB Admin Solu Sample Questions:

1. You administer a SQL Server 2008 instance named Instance1 at the New York central site. Your company has a sales team to fulfill purchase orders for customer requests.
The sales team uses portable computers to update data frequently in a local database. When the portable computers connect to the central site, the local database must be synchronized with a database named Sales.
You plan to create a replication model to replicate the local database to the Sales database.
The replication model must meet the following requirements:
Data conflicts are handled when multiple users update the same data independently.
The sales team cannot update sensitive data such as product price.
The sales team can synchronize data at scheduled times and on demand also.
You need to identify the best model to replicate data by using minimum development efforts.
What should you do?

A) Use snapshot replication along with each portable computer that is set up as a subscriber.
B) Use SQL Server Integration Services (SSIS) to push data changes and pull updates to the Sales database along with the SSIS packages, on demand.
C) Use transactional replication along with each portable computer that is set up as a publisher.
D) Use merge replication along with each portable computer that is set up as a subscriber.

2. You are a professional level SQL Sever 2008 Database Administrator.
An instance runs on a computer, and the computer has eight quad-core processors and 128-GB RAM. The instance is utilized by four different applications. Not only a low number of CXPACKET waits but also a large number of lazy writer waits are experienced by the instance. The performance of the instance should be optimized.
Which action will you perform to accomplish the goal?

A) To accomplish the goal, an increase should be configured in the maximum degree of parallelism option.
B) To accomplish the goal, the Windows System Resource Manager should be configured.
C) To accomplish the goal, the Resource Governor should be configured.
D) To accomplish the goal, software non-uniform memory access (soft-NUMA) should be configured.

3. 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 page-level data compression on the 16 tables that remain static.
B) Use page-level data compression on the 4 tables that are loaded every night.
C) Use row-level data compression on the 16 tables that remain static.
D) Use row-level data compression on the 4 tables that are loaded every night.

4. You administer a SQL Server 2008 instance.
The instance hosts a database that is used by a Web-based application. The application processes 15,000 transactions every minute. A table in the database contains a column that is used only by the application. This column stores sensitive data.
You need to store the sensitive data in the most secure manner possible.
You also need to ensure that you minimize the usage of memory space and processor time.
Which encryption type should you use?

A) Certificate-based encryption
B) Symmetric key encryption
C) Transparent data encryption
D) Asymmetric key encryption

5. You are a professional level SQL Sever 2008 Database Administrator.
The security requirements should be designed for a new database application. A code segment is utilized by the application, and the code segment includes the following components:
A method that the registry is accessed on the SQL Server
A method that the file system is accessed on a network file server
A class definition that public static fields are utilized
SQL CLR integration is utilized by the code segment
The code segment is implemented as a single assembly.
Since you are the technical support, you are required to make sure that the application should be successfully deployed to the instance.
Which action will you perform?

A) All public static fields should be replaced with public fields.
B) The SAFE code access security should be utilized for the assembly.
C) All public static fields should be utilized with public static read-only fields. And then the assembly should be registered by utilizing the regasm.exe utility before deployment.
D) All public static fields should be replaced with public static read-only fields. And then the EXTERNAL_ACCESS code access security should be utilized for the assembly.
