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

1. 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)) {
...
}
using (TransactionScope scope2 = new TransactionScope(TransactionScopeOption.RequiresNew)) { .... } }
B) try
{ using (TransactionScope scope1 = new TransactionScope(TransactionScopeOption.Required)) {
....
try
{
.....
using (TransactionScope scope2 = new TransactionScope
(TransactionScopeOption.RequiresNew))
{ .... }
}
}
}
C) try
{
using (TransactionScope scope1 = new TransactionScope(TransactionScopeOption)
{
....
try
{
.....
using (TransactionScope scope2 = new TransactionScope(TransactionScopeOption))
{ .... }
}
}
}
D) try
{ using (TransactionScope scope1 = new TransactionScope(TransactionScopeOption.Required)) {
...
using (TransactionScope scope2 = new TransactionScope(TransactionScopeOption.RequiresNew))
{ .... }
......
}
}

2. You use Microsoft .NET Framework 4 to develop an application that connects to a Microsoft SQL Server
2008 database.
The database contains a ClassStudent table that contains the StudentID for students who are enrolled in
the classes.
You add the following stored procedure to the database.
CREATE PROCEDURE [dbo].[GetNumEnrolled] @ClassID INT, @NumEnrolled INT OUTPUT
AS BEGIN SET NOCOUNT ON SELECT @NumEnrolled = COUNT(StudentID)
FROM ClassStudent
WHERE (ClassID = @ClassID)
END
You write the following code. (Line numbers are included for reference only.)
01 private int GetNumberEnrolled(string classID)
02 {
03 using (SqlConnection conn = new SqlConnection(GetConnectionString())
04 {
05 SqlCommand cmd = new SqlCommand("GetNumEnrolled", conn);
06 cmd.CommandType = CommandType.StoredProcedure;
07 SqlParameter parClass = cmd.Parameters.Add("@ClassID", SqlDbType.Int,
4, "classID");
08 SqlParameter parNum = cmd.Parameters.Add("@NumEnrolled",
SqlDbType.Int);
09 ...
10 conn.Open()
11 ...
12 }
13 }
You need to ensure that the GetNumberEnrolled method returns the number of students who are enrolled
for a specific class.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

A) Insert the following code at line 11.
cmd.ExecuteNonQuery();
return (int)parNum.Value;
B) Insert the following code at line 11.
int numEnrolled = 0;
SqlDataReader reader = cmd.ExecuteReader();
while(reader.Read())
{
numEnrolled = numEnrolled + (int)cmd.Parameters["@NumEnrolled"].Value; } return numEnrolled;
C) Insert the following code at line 09.
parNum.Direction = ParameterDirection.Input;
D) Insert the following code at line 09.
parNum.Direction = ParameterDirection.Output;

3. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application.
The application connects to a Microsoft SQL Server 2008 database. The application uses a Microsoft
ADO.NET SQL Server managed provider.
When a connection fails, the application logs connection information, including the full connection string.
The information is stored as plain text in a .config file. You need to ensure that the database credentials are
secure.
Which connection string should you add to the .config file?

A) Data Source=myServerAddress; Initial Catalog=myDataBase; Integrated Security=SSPI; Persist Security Info=true;
B) Data Source=myServerAddress; Initial Catalog=myDataBase; User Id=myUsername; Password=myPassword; Persist Security Info=false;
C) Data Source=myServerAddress; Initial Catalog=myDataBase; Integrated Security=SSPI; Persist Security Info=false;
D) Data Source=myServerAddress; Initial Catalog=myDataBase; User Id=myUsername; Password=myPassword; Persist Security Info=true;

4. You use Microsoft Visual Studio 2010, Microsoft Sync Framework, and Microsoft .NET Framework 4.0 to
create an application.
You have a ServerSyncProvider connected to a Microsoft SQL Server database. The database is hosted on
a Web server.
Users will use the Internet to access the Customer database through the ServerSyncProvider.
You write the following code segment. (Line numbers are included for reference only.)
01 SyncTable customerSyncTable = new SyncTable("Customer");
02 customerSyncTable.CreationOption =
TableCreationOption.UploadExistingOrCreateNewTable;
03 ...
04 customerSyncTable.SyncGroup = customerSyncGroup;
05 this.Configuration.SyncTables.Add(customerSyncTable);
You need to ensure that the application meets the following requirements:
-Users can modify data locally and receive changes from the server.
-Only changed rows are transferred during synchronization. Which code segment should you insert at line 03?

A) customerSyncTable.SyncDirection = SyncDirection.Snapshot;
B) customerSyncTable.SyncDirection = SyncDirection.Bidirectional;
C) customerSyncTable.SyncDirection = SyncDirection.DownloadOnly;
D) customerSyncTable.SyncDirection = SyncDirection.UploadOnly;

5. 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 use Entity SQL of the ADO.NET Entity
Framework to retrieve data from the database.
You need to define a custom function in the conceptual model. You also need to ensure that the function
calculates a value based on properties of the object.
Which two XML element types should you use? (Each correct answer presents part of the solution. Choose
two.)

A) Function
B) DefiningExpression
C) FunctionImport
D) Association
E) Dependent
