Question 1: You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The
application connects to a Microsoft SQL Server 2008 database. The database includes a table named
dbo.Documents that contains a column with large binary data.
You are creating the Data Access Layer (DAL). You add the following code segment to query the
dbo.Documents table. (Line numbers are included for reference only.)
01 public void LoadDocuments(DbConnection cnx)
02 {
03 var cmd = cnx.CreateCommand();
04 cmd.CommandText = "SELECT * FROM dbo.Documents";
05 ...
06 cnx.Open();
07
08 ReadDocument(reader);
09 }
You need to ensure that data can be read as a stream.
Which code segment should you insert at line 07?
A. var reader = cmd.ExecuteReader(CommandBehavior.Default);
B. var reader = cmd.ExecuteReader(CommandBehavior.SchemaOnly);
C. var reader = cmd.ExecuteReader(CommandBehavior.KeyInfo);
D. var reader = cmd.ExecuteReader(CommandBehavior.SequentialAccess);
Correct Answer: D
