В Testking 316v5.0 есть два вопроса, которые мне кажутся одинаковыми,
однако, ответы на них разные



QUESTION NO: 1
You use Visual Studio .NET to create a component named Request. This component includes a
method named AcceptTKRequest, which tries to process new user requests for services.
AcceptTKRequest calls a private function named Validate.
You must ensure that any exceptions encountered by Validate are bubbled up to the parent form of
Request. The parent form will then be responsible for handling the exceptions. You want to
accomplish this goal by writing the minimum amount of code.
What should you do?
A . Use the following code segment in AcceptTKRequest:
this.Validate();

B . Use the following code segment in AcceptTKRequest:
try {
this.Validate();
}
catch(Exception ex) {
throw ex;
}

C. Use the following code segment in AcceptTKRequest:
try {
this.Validate();
}
catch(Exception ex) {
throw new Exception(“Exception in AcceptTKRequest”, ex);
}

D. Create a custom Exception class named RequestException by using the following code segment:
public class RequestException:ApplicationException {
public RequestException():base() {
}
public RequestException
(string message):base(message) {
}

public RequestException(string message,
Exception inner):base(message, inner) {
}
}
In addition, use the following code segment in AcceptTKRequest:
try {
this.Validate();
}
catch(Exception ex) {
throw new RequestException(“Exception in AcceptTKRequest”, ex);
}


Answer: A
Explanation: The unhandled exception automatically will be thrown to the client application. This solution
meets the requirement that the least amount of code should be used.

QUESTION NO: 47
You are the .Net Consultant for TKBank. TKBank wants to allow existing users of their ATM
machines to apply for Internet Banking through their ATM machines. To do this, you use Visual
Studio .NET to create a component named ValidateValidATMUser to verify if the user is a valid
ATM customer. This component includes a method named AcceptValidateValidATMUser, which
tries to process new user ValidateValidATMUsers for services. AcceptValidateValidATMUser calls a
private function named Validate.
You must ensure that any exceptions encountered by Validate are bubbled up to the parent form of
ValidateValidATMUser. The parent form will then be responsible for handling the exceptions. You
want to accomplish this goal by writing the minimum amount of code.
What should you do?


A . Use the following code segment in AcceptValidateValidATMUser:
Me.Validate()
B. Use the following code segment in AcceptValidateValidATMUser:
Try {
Me.Validate() }
Catch Exception ex {
Throw ex
}
C. Use the following code segment in AcceptValidateValidATMUser:
Try {
Me.Validate() }
Catch Exception ex {
Throw new Exception ("Exception in AcceptValidateValidATMUser", ex)
}
D . Create a customer Exception class named ValidateValidATMUserException by the following code
segment:
Public Class ValidateValidATMUserException
070 - 316

Inherits System.ApplicationException
Public New(){
}
Public New (String message){
MyBase.New(message)
}
Public New (String message, Exception inner){
MyBase.New(message, inner)
}
}
In addition, use the following code segment in AcceptValidateValidATMUser:
Try {
Me.Validate(); }
Catch Exception ex {
Throw new ValidateValidATMUserException("Exception in _
AcceptValidateValidATMUser", ex);
}


Answer: B
The unhandled exception automatically will be thrown to the client application. This solution meets the
requirement that the least amount of code should be used. We must throw the exception as it is.


Ответ В мне кажется логичным и в первом случае, но неужели в самом
первом вопросе теста может быть ошибка ?
Или между ними все-таки есть разница ?
Пожалуйста, помогите разобраться
Спасибо

Спасибо
А это тоже ошибка ?

Вопрос 54

Стандартная форма с SqlConnection. SqlDataAdapter. DataSet и связанными с
ней TextBox
И кнопкой Save. по нажатию которой

TestKingDataUdapter.Update(CustomerDataSet)
Но данные не сохраняются, вопрос почему
Ответ -
в метод Update надо передать Connection
TestKingDataUdapter.Update(CustomerDataSet. TestKingConnection)

Но метода Update с двумя параметрами в Help вообще нет !
