Question:
You are writing an application that uses SOAP to exchange data with other applications. You use a Department class that inherits from ArrayList to send objects to another application. The Department object is named dept.
You need to ensure that the application serializes the Department object for transport by using SOAP.
Which code should you use?
A
SoapFormatter= formatter = gcnew SoapFormatter();
array= buffer = gcnew array(dept->Capacity);
MemoryStream= stream = gcnew MemoryStream(buffer);
for each (Object= o in dept) {
formatter->Serialize(stream, o);
}

B
SoapFormatter= formatter = gcnew SoapFormatter();
MemoryStream= stream = gcnew MemoryStream();
for each (Object= o in dept) {
formatter->Serialize(stream, o);
}

C
SoapFormatter= formatter = gcnew SoapFormatter();
array= buffer = gcnew array(dept->Capacity);
MemoryStream= stream = gcnew MemoryStream(buffer);
formatter->Serialize(stream, dept);

D
SoapFormatter= formatter = gcnew SoapFormatter();
MemoryStream= stream = gcnew MemoryStream();
formatter->Serialize(stream, dept);

Question: You write the following code segment to call a function from the Win32 Application Programming Interface (API) by using platform invoke.
string personName = "N?el";
string msg = "Welcome " + personName + " to club ''!";
bool rc = User32API.MessageBox(0, msg, personName, 0);
You need to define a method prototype that can best marshal the string data.
Which code segment should you use?
A
[DllImport("user32", CharSet = CharSet.Ansi)]
public static extern bool MessageBox(int hWnd,
String text,
String caption,
uint type);}

B
[DllImport("user32", CharSet = CharSet.Unicode)]
public static extern bool MessageBox(int hWnd
String text,
String caption,
uint type);
}

C

Question: You develop a service application named PollingService that periodically calls long-running procedures. These procedures are called from the DoWork method.
You use the following service application code.
ref class PollingService : public ServiceBase {
public :
static bool blnExit = false;
protected :
override void OnStart(String= args) {
do {
DoWork();
} while (!blnExit);
}
override void OnStop() {
blnExit = true;
}
private :
void DoWork() {}
};
When you attempt to start the service, you receive the following error message: Could not start the PollingService service on the local computer. Error 1053: The service did not respond to the start or control request in a timely fashion.
You need to modify the service application code so that the service starts properly.
What should you do?
A
Move the loop code into the constructor of the service class from the OnStart method.

B
Drag a timer component onto the design surface of the service. Move the calls to the long- running procedure from the OnStart method into the Tick event procedure of the timer, set the Enabled property of the timer to True, and call the Start method of the timer in the OnStart method.

C
Move the loop code from the OnStart method into the DoWork method.

D
Add a class-level System.Timers.Timer variable to the service class code. Move the call to the DoWork method into the Elapsed event procedure of the timer, set the Enabled property of the timer to True, and call the Start method of the timer in the OnStart method.

Which code segment should you use?
A
TripleDES des = new TripleDESCryptoServiceProvider(); ICryptoTransform crypto = des.
CreateDecryptor();
MemoryStream cipherStream = new MemoryStream(cipherMessage); CryptoStream cryptoStream = new CryptoStream(
cipherStream, crypto, CryptoStreamMode.Read);
string message;
message = new StreamReader(cryptoStream).ReadToEnd();

B
TripleDES des = new TripleDESCryptoServiceProvider(); ICryptoTransform crypto = des. CreateDecryptor(key, iv); MemoryStream cipherStream = new MemoryStream(cipherMessage);CryptoStream cryptoStream =
new CryptoStream(
cipherStream, crypto, CryptoStreamMode.Read);
string message;
message = new StreamReader(cryptoStream).ReadToEnd();

C
TripleDES des = new TripleDESCryptoServiceProvider();
des.BlockSize = cipherMessage.Length;
ICryptoTransform crypto = des.CreateDecryptor(key, iv);
MemoryStream cipherStream = new MemoryStream(cipherMessage); CryptoStream cryptoStream = new CryptoStream(
cipherStream, crypto, CryptoStreamMode.Read);
