Microsoft 70-516 Exam Syllabus Topics:

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

1. You use Microsoft .NET Framework 4.0 to develop an application that connects to a Microsoft SQL Server
2008 database.
You add the following stored procedure to the database.
CREATE PROCEDURE dbo.GetClassAndStudents AS BEGIN
SELECT * FROM dbo.Class
SELECT * FROM dbo.Student
END
You create a SqIConnection named conn that connects to the database.
You need to fill a DataSet from the result that is returned by the stored procedure.
The first result set must be added to a DataTable named Class, and the second result set must be added to
a DataTable named Student.
Which code segment should you use?

A) DataSet ds = new DataSet(); SqlDataAdapter ad = new SqlDataAdapter("GetClassAndStudents", conn); ad.TableMappings.Add("Table", "Class"); ad.TableMappings.Add("Table1", "Student") ; ad.Fill(ds) ;
B) DataSet ds = new DataSet(); SqlDataAdapter ad = new SqlDataAdapter("GetClassAndStudents", conn); ad.Fill(ds);
C) DataSet ds = new DataSet(); SqlDataAdapter ad = new SqlDataAdapter("GetClassAndStudents", conn); ds.Tables.Add("Class"); ds.Tables.Add("Student"); ad.Fill(ds);
D) DataSet ds = new DataSet(); SqlDataAdapter ad = new SqlDataAdapter("GetClassAndStudents", conn); ad.MissingMappingAction = MissingMappingAction.Ignore; ad.Fill(ds, "Class"); ad.Fill(ds, "Student");

2. You use Microsoft .NET Framework 4.0 and the Entity Framework to develop an application.
You create an Entity Data Model that has an entity named Customer. You set the optimistic concurrency
option for Customer.
You load and modify an instance of Customer named loadedCustomer, which is attached to an
ObjectContext named context.
You need to ensure that if a concurrency conflict occurs during a save, the application will load up-to-date
values from
the database while preserving local changes. Which code segment should you use?

A) try {
context.SaveChanges();
}
catch(EntitySqlException ex)
{
context.Refresh(RefreshMode.StoreWins, loadedCustomer);
}
B) try {
context.SaveChanges();
}
catch(OptimisticConcurrencyException ex)
{
context.Refresh(RefreshMode.StoreWins, loadedCustomer);
}
C) try {
context.SaveChanges();
}
catch(OptimisticConcurrencyException ex)
{
context.Refresh(RefreshMode.ClientWins, loadedCustomer);
}
D) try {
context.SaveChanges();
}
catch(EntitySqlException ex)
{
context.Refresh(RefreshMode.ClientWins, loadedCustomer);
}

3. You use Microsoft .NET Framework 4.0 to develop an ASP.NET Web application that connects to a
Microsoft SQL Server 2008 database.
The application uses Integrated Windows authentication in Internet Information Services (IIS) to
authenticate users.
A connection string named connString defines a connection to the database by using integrated security.
You need to ensure that a SqlCommand executes under the application pool's identity on the database
server.
Which code segment should you use?

A) using (var conn = new SqlConnection())
{
conn.ConnectionString = connString;
SqlCommand cmd = null;
using (HostingEnvironment.Impersonate())
{
cmd = new SqlCommand("SELECT * FROM BLOG", conn);
}
conn.Open();
var result = cmd.ExecuteScalar();
}
B) using (var conn = new SqlConnection())
{
conn.ConnectionString = connString;
var cmd = new SqlCommand("SELECT * FROM BLOG", conn);
using (HostingEnvironment.Impersonate())
{
conn.Open();
}
var result = cmd.ExecuteScalar();
}
C) using (var conn = new SqlConneccion())
{
using (HostingEnvironroent.Impersonate())
{
conn.ConnectionString = connString;
}
var cmd = new SqlCommand("SELECT * FROM BLOG, conn);
conn.Open() ;
var result = cmd.ExecuteScalar();
}
D) using (var conn = new SqlConnection(connString))
{
var cmd = new SqlCommand ("SELECT * FROM BLOG, conn);
conn.Open();
using(HostingEnvironment.Impersonate())
{
var result = cmd.ExecuteScalar();
}
}

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 write the following code segment that executes two commands against the database within a
transaction.
(Line numbers are included for reference only.)
01 using(SqlConnection connection = new SqlConnection(cnnStr)) {
02 connnection.Open();
03 SqlTransaction sqlTran = connection.BeginTransaction();
04 SqlCommand command = connection.CreateCommand();
05 command.Transaction = sqlTran;
06 try{
07 command.CommandText = "INSERT INTO Production.ScrapReason(Name)
VALUES('Wrong size')";
08 command.ExecuteNonQuery();
09 command.CommandText = "INSERT INTO Production.ScrapReason(Name)
VALUES('Wrong color')";
10 command.ExecuteNonQuery();
11 ...
l2 }
You need to log error information if the transaction fails to commit or roll back. Which code segment should you insert at line 11?

A) catch (Exception ex){ Trace.WriteLine(ex.Message); try{
sqlTran.Rollback();
}
catch (Exception exRollback){
Trace.WriteLine(exRollback.Message);
}
}
finaly {
sqltran.commit( );
}
B) sqlTran.Commit(); } catch (Exception ex) {
sqlTran.Rollback();
Trace.WriteLine(ex.Message);
}
C) catch (Exception ex) { sqlTran.Rollback();
Trace.WriteLine(ex.Message);
}
finaly {
try {
sqltran.commit( );
}
catch (Exception exRollback) {
Trace.WriteLine(excommit.Message);
}
}
D) sqlTran.Commit(); } catch (Exception ex) {
Trace.WriteLine(ex.Message);
try {
sqlTran.Rollback();
}
catch (Exception exRollback) {
Trace.WriteLine(exRollback.Message);
}
}

5. You are adding a process to the application. The process performs the following actions:
1.Opens a ContosoEntities context object named context1.
2.Loads a Part object into a variable named part1.
3.Calls the Dispose() method on context1.
4.Updates the data in part1.
5.Updates the database by using a new ContosoEntities context object named context2.
You need to update the database with the changed data from part1. What should you do?

A) Add the following code segment before calling SaveChanges() on context2:
context2.Attach(part1);
context2.ObjectStateManager.ChangeObjectState(part1,
System.Data.EntitySate.Modified);
B) Add the following code segment before calling SaveChanges() on context2:
context2.ApplyOriginalValues("Parts", part1);
C) Add the following code segment before calling SaveChanges() on context2:
context2.Attach(part1);
context2.ApplyCurrentValues("Parts", part1);
D) Add the following code segment before calling SaveChanges() on context2:
context2.ApplyCurrentValues("Parts", part1);
