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

1. You have a ContosoEntities context object named context and a Color object stored in a variable named color.
You write the following code:
context.Colors.DeleteObject(color); context.SaveChanges();
When the code runs, it generates the following exception:
System.Data.UpdateException: An error occurred while updating the entries. See
the inner exception for detials. --->
System.Data.SqlClient.SqlException: The DELETE satement conflicted with the
REFERENCE constraint "FK_PartColor".
The conflict occurred in database "Contoso", table "dbo.Parts", column
'ColorId'
You need to resolve the exception without negatively impacting the rest of the application. What should you do?

A) In the database, remove the foreign key association between the Parts table and the Colors table, and then update the entity data model.
B) Change the End2 OnDelete proprety of the FK_PartColor association from None to Cascade
C) Add a transation around the call to the SaveChanges() method and handle the exception by performing a retry.
D) Change the End1 OnDelete proprety of the FK_PartColor association from None to Cascade
E) Add code before the call to the DeleteObject() method to examine the collection of Part objects associated with the Color object and then assign null to the Color property for each Part object.

2. You use Microsoft .NET Framework 4.0 to develop an application that connects to two separate Microsoft
SQL Server 2008 databases.
The Customers database stores all the customer information, and the Orders database stores all the order
information.
The application includes the following code. (Line numbers are included for reference only.)
01 try
02 {
03 conn.Open();
04 tran = conn.BeginTransaction("Order");
05 SqlCommand cmd = new SqlCommand();
06 cmd.Connection = conn;
07 cmd.Transaction = tran;
08 tran.Save("save1");
09 cmd.CommandText = "INSERT INTO [Cust].dbo.Customer " + "(Name,
PhoneNumber) VALUES ('Paul Jones', " + "'404-555-1212')";
10 cmd.ExecuteNonQuery();
11 tran.Save("save2");
12 cmd.CommandText = "INSERT INTO [Orders].dbo.Order " + "(CustomerID)
VALUES (1234)";
13 cmd.ExecuteNonQuery();
14 tran.Save("save3");
15 cmd.CommandText = "INSERT INTO [Orders].dbo." + "OrderDetail (OrderlD,
ProductNumber) VALUES" + "(5678, 'DC-6721')";
16 cmd.ExecuteNonQuery();
17 tran.Commit();
18 }
19 catch (Exception ex)
20 {
21 ...
22 }
You run the program, and a timeout expired error occurs at line 16. You need to ensure that the customer
information is saved in the database.
If an error occurs while the order is being saved, you must roll back all of the order information and save the
customer information.
Which line of code should you insert at line 21?

A) tran.Rollback(); tran.Commit();
B) tran.Rollback("save2"); tran.Commit();
C) tran.Rollback("save2");
D) tran.Rollback();

3. You need to ensure that an exception is thrown when color names are set to less than two characters. What should you do?

A) Add the following method to the Color partial class in Model\Color.cs:
protected overrride void OnPropertyChanged(string property)
{
if (property == "Name" && this.Name.Length < 2)
throw new ArgumentOutOfRangeException("Name must be at least two
characters");
}
B) Add the following code segment to the ContosoEntities partial class in Model\ContosoEntities.cs:
public override in SaveChanges(System.Data.Objects.SaveOptions options)
{
var changes = this.ObjectStateManager.GetObjectSateEntries
(System.Data.EntityState.Added);
foreach (var change in changes)
{
if (change.Entity is Color) if (((Color)change.Entity.Name.Length < 2) throw new ArgumentException ("Name too short");
}
return base.SaveChanges(options);
}
C) Add the following attribute to the Name property of the Color class in the entity designer file:
[StringLength(256, MinimumLength = 2)]
D) Add the following method to the Color partial class in Model\Color.cs:
protected overrride void OnPropertyChanging(string property)
{
if (property == "Name" && this.Name.Length < 2)
throw new ArgumentOutOfRangeException("Name must be at least two
characters");
}

4. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to develop an application. You use the Entity Framework Designer to create an Entity Data Model using model-first development.
The database has the following requirements:
-each table must have a datetime column named time_modified
-each table requires a trigger that updates the value of the time_modified column when a row is inserted or updated
You need to ensure that the database script that is created by using the Generate Database From Model
option meets the requirements.
What should you do?

A) Create a new T4 template, and set the DDL Generation template to the name of the new template.
B) Create a new Windows Workflow Foundation workflow, and set Database Generation Workflow to the name of the new workflow.
C) Add a DateTime property named time_modified to each entity in the model and set the property's StoreGeneratedPattern to Computed.
D) Add a new entity named time_modified to the model, and modify each existing entity so that it inherits from the new entity.

5. The user interface requires that a paged view be displayed of all the products sorted in alphabetical order.
The user interface supplies a current starting index and a page size in variables named startIndex and
pageSize of type int.
You need to construct a LINQ expression that will return the appropriate Parts from the database from an
existing
ContosoEntities context object named context. You begin by writing the following expression:
context.Parts
Which query parts should you use in sequence to complete the expression?
(To answer, move the appropriate actions from the list of actions to the answer area and arrange them in
the correct order.)

A) .Take(pageSize);
B) .Skip(pageSize)
C) .Take(startIndex)
D) .Skip(startIndex)
E) .OrderBy(x => x.Name)
