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 develop an application that
uses the Entity Framework.
The application has an entity model that contains a SalesOrderHeader entity. The entity includes an
OrderDate property of type DateTime.
You need to retrieve the 10 oldest SalesOrderHeaders according to the OrderDate property.
Which code segment should you use?

A) var model = new AdventureWorksEntities(); var sales = model.SalesOrderHeaders.OrderBy(soh => soh.OrderDate).Take(10);
B) var model = new AdventureWorksEntities(); var sales = model.SalesOrderHeaders.OrderByDescending(soh => soh.OrderDate).Take(10);
C) var model = new AdventureWorksEntities(); var sales = model.SalesOrderHeaders.Take(10).OrderByDescending(soh => soh.OrderDate);
D) var model = new AdventureWorksEntities(); var sales = model.SalesOrderHeaders.Take(10).OrderBy(soh => soh.OrderDate);

2. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create a Windows
Communication
Foundation (WCF) Data Services service. You deploy the data service to the following URL: http://
contoso.com/Northwind.svc.
You add the following code segment. (Line numbers are included for reference only.)
01 var uri = new Uri(@"http://contoso.com/Northwind.svc/");
02 var ctx = new NorthwindEntities(uri);
03 var categories = from c in ctx.Categories select c;
04 foreach (var category in categories) {
05 PrintCategory(category);
06 ...
07 foreach (var product in category.Products) {
08 ...
09 PrintProduct(product);
10 }
11 }
You need to ensure that the Product data for each Category object is lazy-loaded. What should you do?

A) Add the following code segment at line 06:
ctx.LoadProperty(category, "Products");
B) Add the following code segment at line 08:
ctx.LoadProperty(product, "*");
C) Add the following code segment at line 08:
var strprdUri= string.format("Products?$filter=CategoryID eq {0}",
category.CategoryID);
var prodcutUri = new Uri(strPrd, UriKind.Relative);
ctx.Execute<Product>(productUri);
D) Add the following code segment at line 06:
var strPrdUri = string.Format("Categories({0})?$expand=Products",
category.CategoryID);
var productUri = new Uri(strPrdUri, UriKind.Relative);
ctx.Execute<Product>(productUri);

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

4. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application.
The application connects to a Microsoft SQL Server database. You load records from the Customers table
into a DataSet object named dataset.
You need to retrieve the value of the City field from the first and last records in the Customers table.
Which code segment should you use?

A) DataRelation relationFirst = dataset.Relations[0]; DataRelation relationLast = dataset.Relations[dataset.Relations.Count - 1]; string first = relationFirst.childTable.Columns["City"].ToString(); string last = relationLast.childTable.Columns["City"].ToString();
B) DataTable dt = dataset.Tables["Customers"]; string first = dt.Rows[0]["City"].ToString(); string last = dt.Rows[dt.Rows.Count]["City"].ToString();
C) DataRelation relationFirst = dataset.Relations[0]; DataRelation relationLast = dataset.Relations[dataset.Relations.Count]; string first = relationFirst.childTable.Columns["City"].ToString(); string last = relationLast.childTable.Columns["City"].ToString();
D) DataTable dt = dataset.Tables["Customers"]; string first = dt.Rows[0]["City"].ToString(); string last = dt.Rows[dt.Rows.Count - 1]["City"].ToString();

5. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to develop an application that
connects to a Microsoft SQL Server 2008 database.
You use the ADO.NET Entity Framework Designer to model entities. You add the following stored
procedure to the database, and you add a function import to the model.
CREATE PROCEDURE [dbo].[InsertDepartment] @Name nvarchar(50), @ID int NULL OUTPUT
AS INSERT INTO Department (Name) VALUES (@Name) SELECT @ID = SCOPE_IDENTITY()
You need to insert a new department and display the generated ID. Which code segment should you use?

A) using (SchoolEntities context = new SchoolEntities())
{
var id = context.InsertDepartment("Department 1", null);
Console.WriteLine(id);
}
B) using (SchoolEntities context = new SchoolEntities())
{
var id = new ObjectParameter("ID", typeof(int));
context.InsertDepartment("Department 1", id);
Console.WriteLine(id.Value);
}
C) using (SchoolEntities context = new SchoolEntities())
{
ObjectParameter id = null;
context.InsertDepartment("Department 1", id);
Console.WriteLine(id.Value);
}
D) using (SchoolEntities context = new SchoolEntities())
{
var id = new ObjectParameter("ID", null));
context.InsertDepartment("Department 1", id);
Console.WriteLine(id.Value);
}
