You have just graduated from college, now you are serving the internship as the software developer in an international company. There's an array of bytes that is passed to the method in a parameter named document. You are writing a method to compress the array. You have to compress the incoming array of bytes and return the result as an array of bytes. In the options below, which segment should you use?

• A. Dim objStream As New MemoryStream()Dim objDeflate As New DeflateStream(objStream, CompressionMode.Compress)Dim outStream As New MemoryStreamDim b As IntegerWhile (b = objDeflate.ReadByte) outStream.WriteByte(CByte(b))End WhileReturn outStream.ToArray
• B. Dim objStream As New MemoryStream()Dim objDeflate As New DeflateStream(objStream, CompressionMode.Compress)objDeflate.Write(document, 0, document.Length)objDeflate.Close()Return objStream.ToArray
• C. Dim objStream As New MemoryStream(document)Dim objDeflate As New DeflateStream(objStream, CompressionMode.Compress)Dim result(document.Length) As ByteobjDeflate.Write(result, 0, result.Length)Return result
• D. Dim objStream As New MemoryStream(document)Dim objDeflate As New DeflateStream(objStream, CompressionMode.Compress)objDeflate.Write(document, 0, document.Length)objDeflate.Close()Return objStream.ToArray

You have just graduated from college,now you are serving the internship as the software developer in an international company. According to the requirements of the company CIO, you're developing a server. The application will transmit sensitive information on a network. You create two objects, one is an X509Certificate object named certificate, the other is a TcpClient object named client. Now you have to use the Transport Layer Security 1.0 protocol to create an SslStream to communicate. In the options below, which code segment should you use?

• A. Dim objSSL As New SslStream(client.GetStream)objSSL.AuthenticateAsServer(certificate, False, _ SslProtocols.None, True)
• B. Dim objSSL As New SslStream(client.GetStream)objSSL.AuthenticateAsServer(certificate, False, _
  SslProtocols.Ssl2, True)
• C. Dim objSSL As New SslStream(client.GetStream)objSSL.AuthenticateAsServer(certificate, False, _ SslProtocols.Tls, True)
• D. Dim objSSL As New SslStream(client.GetStream)objSSL.AuthenticateAsServer(certificate, False, _ SslProtocols.Ssl3, True)

You work as the developer in an IT company. Recently your company has a big customer. The customer runs a large supermarket chain. You're appointed to provide technical support for the customer. Now you are creating a class library according to the customer requirement. The class library contains the class hierarchy defined in the following code segment. (Line numbers are included for reference only.)
1 public class Group {
2 public Employee[] Employees;
3 }
4 public class Employee {
5 public string Name;
6 }
7 public class Manager : Employee {
8 public int Level;
9 }
You create an instance of the Group class then populate the fields of the instance. You receive InvalidOperationException when you use the Serialize method of the XmlSerializer class to serialize the instance. Besides this, you receive the following error message: "There was an error generating the XML document."
In order to successfully use the XmlSerializer class to serialize instances of the Group class, you have to modify the code segment. And you must make sure that the XML output contains an element for all public fields in the class hierarchy.
What should you do?

• A. Insert the following code between lines 1 and 2 of the code segment: [XmlArray(ElementName="Employees")]
• B. Insert the following code between lines 1 and 2 of the code segment: [XmlElement(Type = typeof(Employees))]
• C. Insert the following code between lines 3 and 4 of the code segment: [XmlElement(Type = typeof(Employee))] andInsert the following code between lines 6 and 7 of the code segment: [XmlElement(Type = typeof(Manager))]
• D. Insert the following code between lines 1 and 2 of the code segment: [XmlArrayItem(Type = typeof(Employee))] [XmlArrayItem(Type = typeof(Manager))]
