Microsoft 070-516 Exam Syllabus Topics:

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

Question 1

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to develop an application that
uses the Entity Framework.
You create the following Entity Data Model.

You add the following code fragment:
using(var context = new AdventureWorksLTEntities())
{ Customer cust = context.Customers.First(); cust.CompanyName = "Contoso"; int count = 0;
}
The changes to the cust entity must be saved. If an exception is thrown, the application will attempt to save
up to 3 times.
If not, an exception is thrown. Which code segment should you use?

A. while(count++ < 3)
{
try
{
context.SaveChanges();
break;
}
catch(Exception)
{
}
}
B. while(cust.EntityState == EntityState.Modified)
{
try
{
context.SaveChanges();
}
catch(Exception)
{
if(count++ > 2 && context.Connection.State ==
ConnectionState.Broken
{
throw new Exception();
}
}
}
C. while(context.ObjextStateManager.GetObjectStateEntry (cust).OriginalValues.IsDBNull(0)) {
if(count++ >2)
{
break;
}
context.SaveChanges();
}
D. while(true)
{ context.SavingChanges += delegate(System.Object o, System.EventArgs e) {
if(count++ >2)
{
throw new Exception();
}
context.SaveChanges();
}
}

Question 2

You use Microsoft .NET Framework 4.0 to develop an application that connects to a Microsoft SQL Server
2008 database.
You add the following table to the database.
CREATE TABLE Orders( ID numeric(18, 0) NOT NULL, OrderName varchar(50) NULL, OrderTime time(7) NULL, OrderDate date NULL)
You write the following code to retrieve data from the OrderTime column. (Line numbers are included for reference only.)
01 SqlConnection conn = new SqlConnection("...");
02 conn.Open();
03 SqlCommand cmd = new SqlCommand("SELECT ID, OrderTime FROM Orders", conn);
04 SqlDataReader rdr = cmd.ExecuteReader();
05 ....
06 while(rdr.Read())
07 {
08 ....
09 }
You need to retrieve the OrderTime data from the database. Which code segment should you insert at line 08?

A. TimeSpan time = (TimeSpan)rdr[1];
B. Timer time = (Timer)rdr[1];
C. string time = (string)rdr[1];
D. DateTime time = (DateTime)rdr[1];

Question 3

You use Microsoft .NET Framework 4.0 to develop an application that uses LINQ to SQL.
The Product entity in the LINQ to SQL model contains a field named Productlmage. The Productlmage field
holds a large amount of binary data.
You need to ensure that the Productlmage field is retrieved from the database only when it is needed by the
application. What should you do?

A. When the context is initialized, specify that the Productlmage property should not be retrieved by using DataLoadOptions
B. Set the Auto-Sync property on the Productlmage property of the Product entity to Never.
C. Set the Delay Loaded property on the Productlmage property of the Product entity to True.
D. Set the Update Check property on the Productlmage property of the Product entity to Never.

Question 4

The database contains a table named Categories. The Categories table has a primary key identity column
named CategoryID.
The application inserts new records by using the following stored procedure.
CREATE PROCEDURE dbo.InsertCategory @CategoryName nvarchar(15), @Identity int OUT
AS INSERT INTO Categories (CategoryName) VALUES(@CategoryName) SET @Identity = SCOPE_IDENTITY() RETURN @@ROWCOUNT
You write the following code segment.
SqlDataAdapter adapter = new SqlDataAdapter("SELECT categoryID, CategoryName
FROM dbo.Categories",connection);
adapter.InsertCommand = new SqlCommand("dbo.InsertCategory", connection);
adapter.InsertCommand.CommandType = commandType.StoredProcedure;
adapter.InsertCommand.Parameters.Add(new SqlParameter("@CategoryName",
SqlDbType.NVarChar, 15,"CategoryName"));
You need to retrieve the identity value for the newly created record. Which code segment should you add?

A. SqlParameter parameter = adapter.InsertCommand.Parameters.Add("@CategoryName", SqlDbType.Int); parameter.Direction = ParameterDirection.Output; parameter = adapter.InsertCommand.Parameters.Add("@Identity", SqlDbType.Int, 0, "CategoryID"); parameter.Direction = ParameterDirection.Output;
B. SqlParameter parameter = adapter.InsertCommand.Parameters.Add("@CategoryName", SqlDbType.Int); parameter.Direction = ParameterDirection.Output; parameter = adapter.InsertCommand.Parameters.Add("@Identity", SqlDbType.Int, 0, "CategoryID"); parameter.Direction = ParameterDirection.ReturnValue;
C. SqlParameter parameter = adapter.InsertCommand.Parameters.Add("@RowCount", SqlDbType.Int);
parameter.Direction = ParameterDirection.Output;
parameter = adapter.InsertCommand.Parameters.Add("@Identity", SqlDbType.Int, 0, "CategoryID");
parameter.Direction = ParameterDirection.ReturnValue;
D. SqlParameter parameter = adapter.InsertCommand.Parameters.Add("@RowCount", SqlDbType.Int); parameter.Direction = ParameterDirection.ReturnValue; parameter = adapter.InsertCommand.Parameters.Add("@Identity", SqlDbType.Int, 0, "CategoryID"); parameter.Direction = ParameterDirection.Output;

Question 5

You are a tasked with performing a code review. The business rule is the following:
-If INSERTs into the first table succeed, then INSERT into the second table.
-However, if the INSERTs into the second table fail, roll back the inserts in the second table but do not roll back the inserts in the first table.
-Although this can also be done by way of regular transactions, It needs to be performed using
TransactionScope objects.
Whis code would fit this business rule?

A. try
{ using (TransactionScope scope1 = new TransactionScope(TransactionScopeOption.Required)) {
....
try
{
.....
using (TransactionScope scope2 = new TransactionScope
(TransactionScopeOption.RequiresNew))
{ .... }
}
}
}
B. try
{
using (TransactionScope scope1 = new TransactionScope(TransactionScopeOption)
{
....
try
{
.....
using (TransactionScope scope2 = new TransactionScope(TransactionScopeOption))
{ .... }
}
}
}
C. try
{ using (TransactionScope scope1 = new TransactionScope(TransactionScopeOption.Required)) {
...
}
using (TransactionScope scope2 = new TransactionScope(TransactionScopeOption.RequiresNew)) { .... } }
D. try
{ using (TransactionScope scope1 = new TransactionScope(TransactionScopeOption.Required)) {
...
using (TransactionScope scope2 = new TransactionScope(TransactionScopeOption.RequiresNew))
{ .... }
......
}
}
