Answer & Solution

Answer: Option B

Solution:

It provides fallback for IE8.

You are developing a method to hash data for later verification by using the MD5 algorithm. The data is passed to your method as a byte array named message. You need to compute the hash of the incoming parameter by using MD5. You also need to place the result into a byte array. Which code segment should you use?

HashAlgorithm algo = HashAlgorithm.Create("MD5");
byte[] hash = algo.ComputeHash(message);

✘

HashAlgorithm algo = HashAlgorithm.Create("MD5");byte[] hash = BitConverter.GetBytes(algo.GetHashCode());

✘

HashAlgorithm algo;algo = HashAlgorithm.Create(message.ToString());byte[] hash = algo.Hash;

✘

HashAlgorithm algo = HashAlgorithm.Create("MD5");byte[] hash = null;
algo.TransformBlock(message, 0,
message.Length, hash, 0);

You are developing a server application that will transmit sensitive information on a network. You create an X509Certificate object named certificate and a TcpClient object named client. You need to create an SslStream to communicate by using the Transport Layer Security 1.0 protocol. Which code segment should you use?

SslStream ssl = new SslStream(client.GetStream());
ssl.AuthenticateAsServer( certificate, false, SslProtocols.None, true);

✘

SslStream ssl = new SslStream(client.GetStream());ssl.AuthenticateAsServer( certificate, false, SslProtocols.Ssl3, true);

✘

SslStream ssl = new SslStream(client.GetStream());ssl.AuthenticateAsServer( certificate, false, SslProtocols.Ssl2, true);

✘

SslStream ssl = new SslStream(client.GetStream());ssl.AuthenticateAsServer( certificate, false, SslProtocols.Tls, true);

You create an application to send a message by e-mail. An SMTP server is available on the local subnet. The SMTP server is named smtp.contoso.com. To test the application, you use a source address, me@contoso.com, and a target address, you@contoso.com. You need to transmit the e-mail message. Which code segment should you use?

✘

string strSmtpClient = "smtp.contoso.com";string strFrom = "me@contoso.com";string strTo = "you@contoso.com";string strSubject = "Greetings!"; string strBody = "Test";MailMessage msg = new MailMessage(strFrom, strTo, strSubject, strSmtpClient);

✘

MailAddress addrFrom = new MailAddress("me@contoso.com");MailAddress addrTo = new MailAddress("you@contoso.com");
MailMessage message = new MailMessage(addrFrom, addrTo);
message.Subject = "Greetings!";message.Body = "Test"; SmtpClient client = new SmtpClient("smtp.contoso.com");
client.Send(message);

✘

MailAddress addrFrom = new MailAddress("me@contoso.com", "Me");MailAddress addrTo = new MailAddress("you@contoso.com", "You"); MailMessage message = new MailMessage(addrFrom, addrTo); message.Subject = "Greetings!";message.Body = "Test"; SocketInformation info = new SocketInformation(); Socket client = new Socket(info); System.Text.ASCIIEncoding enc = new System.Text.ASCIIEncoding();
byte[] msgBytes = enc.GetBytes(message.ToString());
client.Send(msgBytes);
