which is hosted by a server, named CERTKINGDOM-SR13. You then created a storage schema
definition file, a conceptual schema definition file, and a mapping schema definition file. The files
are named CertKingdom.ssdl, CertKingdom.csdl, and CertKingdom.msl respectively.
After modifying the contents of the conceptual schema definition file and the mapping schema
definition file, you are required to create the .NET Framework entities from the modified schema
definitions.
You have decided to make use of the Edmgen.exe tool.
Which of the following actions should you take?

A. You should consider making use of the EntityClassGeneration mode.
B. You should consider making use of the FromSsdlGeneration mode.
C. You should consider making use of the ValidateArtifacts mode.
D. You should consider making use of the FullGeneration mode.

Answer: A


QUESTION 2
You work as an application developer at CertKingdom.com. You are making use of .NET Framework
3.5, as well as Microsoft ADO.NET for application development.
You have recently developed an application that has two entities named CKDClient and CKDOrders.
The CKDClient entity has a navigable property, named CKDOrders, which returns a collection of
CKDOrders entity instances.
You have been instructed to create code that returns the corresponding CKDOrders entity instances
when a CKDClient entity instance is queried.
Which of the following actions should you take?

A. You should construct the following code:
CKDEntities context = new CKDEntities();
ObjectQuery<CKDClient> query;
query = context.Client.Include(“CKDOrders”);
B. You should construct the following code:
CKDEntities context = new CKDEntities();
ObjectQuery<CKDClient> query;
query = context.Client.Insert(“CKDOrders”);
C. You should construct the following code:
CKDEntities context = new CKDEntities();
ObjectQuery<CKDClient> query;
query = context.Client.Release(“CKDOrders”);
D. You should construct the following code:
CKDEntities context = new CKDEntities();
ObjectQuery<CKDClient> query;
query = context.Client.Remove(“CKDOrders”);

Answer: A


QUESTION 3
You work as an application developer at CertKingdom.com. You are making use of .NET Framework
3.5, as well as Microsoft ADO.NET for application development.
CertKingdom.com has a server, named CERTKINGDOM-SR35, which hosts a Microsoft SQL Server
2005 database named CKDDatabase1. You are in the process of developing a new application that
is linked to CKDDatabase1, which hosts has two tables. Each table is displayed in its own GridView
control using its own SqlConnection object.
You have received instructions to reconfigure the way that the tables are displayed, so that it
makes use of one SqlConnection object to display the tables at the same time.
Which of the following actions should you take?

SqlDataReader objects.
B. In the connection string of the application, have the Multiple Active Result Sets (MARS)
enabled.
C. You should consider making use of the xsd.exe tool.
D. In the connection string of the application, have the Default Result Set enabled.

Answer: B


QUESTION 4
You work as an application developer at CertKingdom.com. You are making use of .NET Framework
3.5, as well as Microsoft ADO.NET for application development.
You are in the process of configuring an application that you recently developed. You have to
configure the application so that it is able to connect to all kinds of databases.
You start by specifying the database driver name in the application’s connection string.
Which of the following actions should you take NEXT?

A. You should make use of ODBC Connection Pooling for creating the connection object.
B. You should make use of the OLE DB Connection Manager for creating the connection object
C. You should consider making use of the subsequent code to construct the connection object:
DSProviderFactory factory = DSProviderFactories.GetFactory(“System.Data”);DbConnection =
CreateConnection();
D. You should consider making use of the subsequent code to construct the connection object:
DbProviderFactory factory =
DbProviderFactories.GetFactory(databaseProviderName);DbConnection connection =
factory.CreateConnection();

Answer: D


QUESTION 5
You work as an application developer at CertKingdom.com. You are making use of .NET Framework
3.5, as well as Microsoft ADO.NET for application development.
