First, the users continuously access to the Orders table in the database.
Secondly, a column of the xml data type is contained by Orders table.
Thirdly, the new rows are regularly added to the Orders table.
Fourthly, the average fragmentation for the clustered index of the Orders table is no more than 2
percent.
A strategy should be designed to have the performance of the queries on the table optimized.
Which action will you perform?

• A.The clustered index of the Orders table should be dropped.
• B.The clustered index of the Orders table offline should be rebuilt once a month.
• C.The clustered index of the Orders table should be reorganized by reducing the fill factor.
• D.The clustered index of the Orders table should be excluded from scheduled reorganizing or rebuilding operations.

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

You administer a SQL Server 2008 instance.
The instance is one of three servers in a peer-to-peer transactional replication topology.
The publication contains a table named Orders. The Orders table contains 200 GB of data
across multiple partitions. A batch process bulk loads 10 GB of data to the Orders table periodically.
You need to design a replication strategy to minimize latency.
What should you do?

• A.Configure the Distributor agent to replicate transactions continually.
• B.Explanation/Reference:
  ---Jeff---
• C.Use the BULK INSERT command in multiple staging tables. Switch partitions into the Orders table.
• D.Disable the Distributor agent. Use the BULK INSERT command in the Orders table. Reinitialize the publication.
• E.Configure the Distributor agent to change the commit batch threshold.

You administer a SQL Server 2008 infrastructure.
Developers in your company have rights to author policies. A test server is used to develop and test the
policies.
The Policy-Based Management feature generates SQL Server Agent alerts when a policy is violated.
The developers are able to create and modify policies, but are unable to test policy violation alerts.
You need to grant the necessary permission to the developers to test the policies. You also need to comply
with
the least privilege principle when you grant the permission.
What should you do?

• A.Grant the EXECUTE permission on the sys.sp_syspolicy_execute_policy stored procedure to the developers.
• B.Grant the ALTER TRACE permission to the developers.
• C.Add the developers to the PolicyAdministratorRole role in the MSDB database.
• D.Add the developers to the sysadmin server role.
