NO.1 You create an application by using the Microsoft .NET Framework 3.5 and Microsoft ADO.NET.
The application uses the following LINQ query. var query = from o in orderLinesQuery where
(string)o["CarrierTrackingNumber"] == "AEB6-4356-80" select new { SalesOrderID =
o.Field("SalesOrderID"), OrderDate = o.Field("OrderDate") }; The CarrierTrackingNumber field in
the DataRow is nullable. You need to ensure that an exception does not occur if the
CarrierTrackingNumber field has a null value. Which code segment should you use?
A.var query = from o in orderLinesQuerywhere !o.IsNull("CarrierTrackingNumber")
&(string)o["CarrierTrackingNumber"] == "AEB6-4356-80"select new { SalesOrderID =
o.Field("SalesOrderID"), OrderDate = o.Field("OrderDate")};
B.var query = from o in orderLinesQuerywhere o.IsNull("CarrierTrackingNumber")
&(string)o["CarrierTrackingNumber"] == "AEB6-4356-80"select new { SalesOrderID =
o.Field("SalesOrderID"), OrderDate = o.Field("OrderDate")};
C.var query = from o in orderLinesQuerywhere o.Field("CarrierTrackingNumber") ==
"AEB6-4356-80"select new { SalesOrderID = o.Field("SalesOrderID"), OrderDate =
o.Field("OrderDate")};
D.var query = from o in orderLinesQuerywhere (string)o["CarrierTrackingNumber"] ==
DbNull.Value &(string)o["CarrierTrackingNumber"] == "AEB6-4356-80"select new { SalesOrderID =
o.Field("SalesOrderID"), OrderDate = o.Field("OrderDate") };

NO.2 You create an application by using the Microsoft .NET Framework 3.5 and Microsoft ADO.NET. The
application connects to a Microsoft SQL Server 2005 database. You write the following code segment.
string query = "Select EmpNo, EmpName from dbo.Table_1; select Name,Age from dbo.Table_2";
SqlCommand command = new SqlCommand(query, connection); SqlDataReader reader =
command.ExecuteReader(); You need to ensure that the application reads all the rows returned by the
code segment. Which code segment should you use?
A.while (reader.NextResult()){ Console.WriteLine(String.Format("{0}, {1}",reader[0], reader[1]));
reader.Read();}
B.while (reader.Read()){ Console.WriteLine(String.Format("{0}, {1}",reader[0], reader[1]));
reader.NextResult();}
C.while (reader.Read()){ Console.WriteLine(String.Format("{0}, {1}",reader[0],
reader[1]));}reader.NextResult();while (reader.Read()){ Console.WriteLine(String.Format("{0},
{1}",reader[0], reader[1]));}

NO.4 You create an application by using the Microsoft .NET Framework 3.5 and Microsoft ADO.NET.
You write the following code segment. DataTable tbl = new DataTable(); DataColumn colId =
tbl.Columns.Add( "ID", typeof(int)); colId.AutoIncrement = true; tbl.Constraints.Add("Pkey", colId,
true); DataColumn colCtry = tbl.Columns.Add( "Country", typeof(string)); colCtry.DefaultValue =
"USA"; tbl.Columns.Add("Name", typeof(string)); You need to create a new row in the tbl
DataTable that meets the following requirements: The ID column is set to an auto-incremented
value. The Country column is set to the default value. The Name column is set to the value
"Customer A". Which code segment should you use?
A.tbl.Rows.Add(0, null, "Customer A");
B.tbl.Rows.Add(null, null, "Customer A");
C.tbl.Rows.Add(null, DBNull.Value, "Customer A");
D.tbl.Rows.Add(DBNull.Value, DBNull.Value, "Customer A");

NO.5 You create an application by using the Microsoft .NET Framework 3.5 and Microsoft ADO.NET.
The application connects to a Microsoft SQL Server 2005 database. The application uses an XML
file that contains product data. A corresponding XSD file contains the schema of the XML file. You
need to ensure that the application performs the following tasks: Loads the XML file in a typed
DataSet Validates the XML file against the schema provided in the XSD file What should you do?
A.Use the xsd.exe tool along with the /loadxml parameter to create a typed DataSet object that
contains the data from the XML file.
B.Use the xsd.exe tool along with the /dataset parameter to generate a typed DataSet object.Use
the DataSet.ReadXml method to load the typed DataSet object.
C.Add the XSD file to the schema collections of the XmlReader object.Load the XML file in the
XmlReader object.Iterate through the XML nodes of the XMLReader object to create a new typed
DataRow for each node.
D.Load the XML file in an XmlDocument object.Call the XmlDocument.Validate method to validate
the XML file against the schema.Iterate through the XML nodes of the XmlDocument object to
create a new typed DataRow for each node.

NO.6 You create an application by using the Microsoft .NET Framework 3.5 and Microsoft ADO.NET.
The application connects to a Microsoft SQL Server 2005 database. You write the following code
segment. (Line numbers are included for reference only.) 01 SqlConnection sqlconn 02 ... 03
SqlDataAdapter ordAdapter = 04 new SqlDataAdapter( 05 "SELECT OrderID, CustomerID,
OrderDate, Qty, UnitPrice,"+ 06 "UnitMargin FROM Sales.SalesOrderDetail", sqlconn); 07 DataSet
ord_ds = new DataSet(); 08 DataTable ord_dt = ord_ds.Tables.Add("Orders"); 09
ordAdapter.Fill(ord_dt); 10 ord_dt.Rows[0].BeginEdit(); 11 // The code here will insert, update and
delete rows to the ord_dt DataTable. 12 ord_dt.Rows[0].EndEdit(); 13 14 ord_dt.AcceptChanges();
You need to validate that every row that has the Qty column value is set to zero before you commit
any changes. Which code segment should you insert at line 13?
A.DataRow[] newRows = ord_dt.Select(null, null, DataViewRowState.CurrentRows);foreach
(DataRow newrow in newRows){ if(newrow.Field("Qty",DataRowVersion.Current) == 0) ...}
B.DataRow[] newRows = ord_dt.Select(null, null, DataViewRowState.CurrentRows);foreach
(DataRow newrow in newRows){ if(newrow.Field("Qty",DataRowVersion.Original) == 0) ...}
C.DataRow[] newRows = ord_dt.Select(null, null, DataViewRowState.ModifiedCurrent);foreach
(DataRow newrow in newRows){ if(newrow.Field("Qty",DataRowVersion.Current) == 0) ...}

NO.7 You create an application by using the Microsoft .NET Framework 3.5 and Microsoft ADO.NET.
The application has a DataTable object named OrderDetailTable. The object has the following
columns: ID OrderID ProductID Quantity LineTotal The OrderDetailTable object is populated with
data provided by a business partner. Some of the records contain a null value in the LineTotal field
and 0 in the Quantity field. You write the following code segment. (Line numbers are included for
reference only.) 01 DataColumn col = new DataColumn("UnitPrice", typeof(decimal)); 02 03
OrderDetailTable.Columns.Add(col); You need to add a DataColumn named UnitPrice to the
OrderDetailTable object. Which line of code should you insert at line 02?
A.col.Expression = "LineTotal/Quantity";
B.col.Expression = "LineTotal/ISNULL(Quantity, 1)";
C.col.Expression = "LineTotal.Value/ISNULL(Quantity.Value,1)";

c.CustomerID=1
C.SELECT o.InvoiceNo FROM ContosoEntities.Order as o WHERE (Select REF(c) from
ContosoEntities.Customer as c WHERE CustomerID=1)
D.SELECT o.InvoiceNo FROM ContosoEntities.Order as o, o.Customer as c WHERE
