Microsoft TS: Accessing Data with Microsoft .NET Framework 4 Sample Questions:

1. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application. You create stored procedures by using the following signatures:
CREATE procedure [dbo].[Product_Insert](@name varchar(50),@price float)
CREATE procedure [dbo].[Product_Update](@id int, @name varchar(50), @price
float)
CREATE procedure [dbo].[Product_Delete](@id int)
CREATE procedure [dbo].[Order_Insert](@productId int, @quantity int)
CREATE procedure [dbo].[Order_Update](@id int, @quantity int,@originalTimestamp
timestamp)
CREATE procedure [dbo].[Order_Delete](@id int)
You create a Microsoft ADO.NET Entity Data Model (EDM) by using the Product and Order entities as shown in the exhibit:

You need to map the Product and Order entities to the stored procedures. To which two procedures should

(Each correct answer presents part of the solution. Choose two.)

A) Product_Update
B) Order_Delete
C) Order_Update
D) Product_Delete

2. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create a Windows

A) Enable the WCF Authentication Service.
B) Modify the Data Services service to use a Microsoft ASP.NET membership provider.
C) Configure IIS to require Windows authentication.
D) Configure IIS to require basic authentication.
E) Configure IIS to allow anonymous access.

3. The database contains orphaned Color records that are no longer connected to Part records.
You need to clean up the orphaned records. You have an existing ContosoEntities context object named
context.
Which code segment should you use?

A) context.Colors.ToList().RemoveAll(c => !c.Parts.Any()); context.SaveChanges();
B) var unusedColors = context.Colors.Where(c => !c.Parts.Any()).ToList(); foreach (var unused in unusedColors){
context.DeleteObject(unused)
}
context.SaveChanges();
C) context.Colors.TakeWhile(c => !c.Parts.Any()); context.SaveChanges();
D) var unusedColors = context.Colors.Where(c => !c.Parts.Any()); context.DeleteObject(unusedColors); context.SaveChanges();

4. You use Microsoft .NET Framework 4.0 to develop an application that connects to a Microsoft SQL Server
200B database.
You populate a SqlDataAdapter by using the following code. (Line numbers are included for reference only.)
01 SqlDataAdapter dataAdapter1 = new SqlDataAdapter("SELECT * FROM
[BlogEntries] ORDER BY CreationDate", connection);
02 cmdBuilder = new SqlCommandBuilder(dataAdapter1);
03 dataAdapter1.Fill(BlogEntryDataSet, "BlogEntries");
04 ....
05 connection.Close();
You need to update the blog owner for all BlogEntry records. Which code segment should you insert at line 04?

A) foreach(DataRow row in BlogEntryDataSet.Tables["BlogEntries"].Rows) {
row.Item["BlogOwner""] = "New Owner";
}
dataAdapter1.Update(BlogEntryDataSet, "BlogEntries");
B) foreach(DataRow row in BlogEntryDataSet.Tables["BlogEntries"].Rows) {
row.Item["BlogOwner""] = "New Owner";
}
dataAdapter1.Fill(BlogEntryDataSet, "BlogEntries");
C) SqlDataAdapter dataAdapter2 = new SqlDataAdapter(dataAdapterl.UpdateCommand); dataAdapter2.Fill(BlogEntryDataSet, "BlogEntries");
D) SqlDataAdapter dataAdapter2 = new SqlDataAdapter("UPDATE [BlogEntries] SET [BlogOwner] = "New
'Owner' 3", connection);
dataAdapter2.Update(BlogEntryDataSet, "BlogEntries");

5. You use Microsoft .NET Framework 4.0 to develop an ASP.NET 4 Web application.
You need to encrypt the connection string information that is stored in the web.config file. The application is
deployed to multiple servers.
The encryption keys that are used to encrypt the connection string information must be exportable and
importable on all the servers.
You need to encrypt the connection string section of the web.config file so that the file can be used on all of
the servers.
Which code segment should you use?

A) Configuration config = WebConfigurationManager.OpenWebConfiguration("~") ; ConnectionStringsSection section = (ConnectionStringsSection)config.GetSection("connectionStrings"); section.Sectionlnformation.ProtectSection("RsaProtectedConfigurationProvider"); config.Save();
B) Configuration config = WebConfigurationManager.OpenMachineConfiguration ("~") ; ConnectionStringsSection section = (ConnectionStringsSection)config.GetSection ("connectionStrings") ; section.Sectionlnformation.ProtectSection("DpapiProtectedConfigurationProvider"); config.Save () ;
C) Configuration config = WebConfigurationHanager.OpenWebConfiguration ("~") ; ConnectionStringsSection section = (ConnectionStringsSection)config.GetSection ("connectionStrings") ; section.Sectionlnformation.ProtectSection("DpapiProtectedConfigurationProvider"); config.Save ();
