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

1. You use Microsoft .NET Framework 4 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].[InsertTag] @Name nvarchar (15)
AS INSERT INTO [dbo].[Tags] (Name) VALUES(@Name) RETURN @@ROWCOUNT
You need to invoke the stored procedure by using an open SqlConnection named conn. Which code segment should you use?

A) SqlCommand cmd = new SqlCommand("EXEC InsertTag", conn); cmd.CommandType = CommandType.Text; cmd.Parameters.AddWithValue("@Name", "New Tag 1"); cmd.ExecuteNonQuery();
B) SqlCommand cmd = new SqlCommand("InsertTag", conn); cmd.CommandType = CommandType.StoredProcedure; cmd.Parameters.AddWithValue("@Name", "New Tag 1"); cmd.ExecuteNonQuery();
C) SqlCommand cmd = new SqlCommand("InsertTag", conn); cmd.CommandType = CommandType.Text; cmd.Parameters.AddWithValue("@Name", "New Tag 1"); cmd.ExecuteNonQuery();
D) SqlCommand cmd = new SqlCommand("EXEC InsertTag", conn); cmd.CommandType = CommandType.StoredProcedure; cmd.Parameters.AddWithValue("@Name", "New Tag 1"); cmd.ExecuteNonQuery();

2. Which code segment will properly return the TimeSpan returned by the stopWatch variable?

A) Stopwatch stopWatch = new Stopwatch(); stopWatch.Begin(); DoSomething(); stopWatch.End(); TimeSpan ts = stopWatch.Elapsed; string elapsedTime = String.Format("{0:00}:{1:00}:{2:00}.{3:00}", ts.Hours, ts.Minutes, ts.Seconds, ts.Milliseconds / 10); Console.WriteLine(elapsedTime, "RunTime");
private void DoSomething()
{ ... }
B) Stopwatch stopWatch = new Stopwatch();
stopWatch.Start();
DoSomething();
stopWatch.Stop();
TimeSpan ts = stopWatch.Elapsed;
string elapsedTime = String.Format("{0:00}:{1:00}:{2:00}.{3:00}", ts.Hours, ts.Minutes, ts.Seconds,
ts.Milliseconds / 10);
Console.WriteLine(elapsedTime, "RunTime");
private void DoSomething()
{ ... }
C) Stopwatch stopWatch = new Stopwatch(); stopWatch.Start(); DoSomething(); stopWatch.Reset(); TimeSpan ts = stopWatch.Elapsed; string elapsedTime = String.Format("{0:00}:{1:00}:{2:00}.{3:00}", ts.Hours, ts.Minutes, ts.Seconds, ts.Milliseconds / 10); Console.WriteLine(elapsedTime, "RunTime");
private void DoSomething()
{ ... }
D) Stopwatch stopWatch = new Stopwatch(); stopWatch.Start(); DoSomething(); TimeSpan ts = stopWatch.Elapsed; string elapsedTime = String.Format("{0:00}:{1:00}:{2:00}.{3:00}", ts.Hours, ts.Minutes, ts.Seconds, ts.Milliseconds / 10); Console.WriteLine(elapsedTime, "RunTime");
private void DoSomething()
{ ... }

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 database. The application uses DataContexts to query
the database.
The application meets the following requirements:
-Stores customer data offline.
-Allows users to update customer records while they are disconnected from the server.
-Enables offline changes to be submitted back to the SQL Server by using the DataContext object.
You need to ensure that the application can detect all conflicts that occur between the offline customer information submitted to the SQL Server and the server version. You also need to ensure that you can roll back local changes. What should you do?

A) Override the Update operation of the DataContext object. Call the ExecuteDynamicUpdate method to generate the update SQL.
B) Add a try/catch statement around calls to the SubmitChanges method of the DataContext object and catch SqlExceptions.
C) Call the SubmitChanges method of the DataContext object. Pass System.Data.Linq.ConflictMode.ContinueOnConflict to the method.
D) Add a try/catch statement around calls to the SubmitChanges method of the DataContext object and catch ChangeConflictExceptions.

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 use Entity SQL to retrieve data from the
database.
You need to find out whether a collection is empty. Which entity set operator should you use?

A) ANYELEMENT
B) EXISTS
C) IN
D) EXCEPT

5. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application.
The application uses the ADO.NET Entity Framework to model entities.
The conceptual schema definition language (CSDL) file contains the following XML fragment.
<EntityType Name="Contact"> ... <Property Name="EmailPhoneComplexProperty"
Type="AdventureWorksModel.EmailPhone" Nullable="false" />
</EntityType>
...
<ComplexType Name="EmailPhone">
<Property Type="String" Name="EmailAddress" MaxLength="50" FixedLength="false" Unicode="true" />
<Property Type="String" Name="Phone" MaxLength="25" FixedLength="false" Unicode="true" /> </ComplexType>
You write the following code segment. (Line numbers are included for reference only.)
01 using (EntityConnection conn = new EntityConnection("name=AdvWksEntities"))
02 {
03 conn.Open();
04 string esqlQuery = @"SELECT VALUE contacts FROM
05 AdvWksEntities.Contacts AS contacts
06 WHERE contacts.ContactID == 3";
07 using (EntityCommand cmd = conn.CreateCommand())
08 {
09 cmd.CommandText = esqlQuery;
10 using (EntityDataReader rdr = cmd.ExecuteReader())
11 {
12 while (rdr.Read())
13
{
14
...
15
}
16
}
17
}
18 conn.Close(); 19 }
You need to ensure that the code returns a reference to a ComplexType entity in the model named
EmailPhone.
Which code segment should you insert at line 14?

A) DbDataRecord nestedRecord = rdr["EmailPhoneComplexProperty"] as DbDataRecord; return nestedRecord;
B) int FldIdx = 0; EntityKey key = record.GetValue(FldIdx) as EntityKey; foreach (EntityKeyMember keyMember in key.EntityKeyValues)
{
return keyMember.Key + " : " + keyMember.Value;
}
C) int fieldCount = rdr["EmailPhone"].DataRecordInfo.FieldMetadata.Count; for (int FldIdx = 0; FldIdx < fieldCount; FldIdx++) {
rdr.GetName(FldIdx);
if (rdr.IsDBNull(FldIdx) == false)
{
return rdr["EmailPhone"].GetValue(FldIdx).ToString();
}
}
D) IExtendedDataRecord record = rdr["EmailPhone"]as IExtendedDataRecord; int FldIdx = 0; return record.GetValue(FldIdx);
