Question:
You are creating an application that retrieves values from a custom section of the application configuration file. The custom section uses XML as shown in the following block.
<ProjectSection name="Project1">
<role name="administrator" />
<role name="manager" />
<role name="support" />
</ProjectSection>
You need to write a code segment to define a class named Role. You need to ensure that the Role class is initialized with values that are retrieved from the custom section of the configuration file.
Which code segment should you use?
A
Public Class Role
Inherits ConfigurationElement
Friend _ElementName As String = "role"
Private _name As String
<ConfigurationProperty("name")>_
Public ReadOnly Property Name() As String
Get
Return _name
End Get
End Property
End Class

B
Public Class Role
Inherits ConfigurationElement
Friend _ElementName As String = "name"
Private _name As String
<ConfigurationProperty("role", IsRequired:=True)> _
Public ReadOnly Property Name() As String Get
Return _name
End Get
End Property
End Class

C
Public Class Role
Inherits ConfigurationElement
Friend _ElementName As String = "role"
<ConfigurationProperty("name", IsRequired:=True)>_
Public ReadOnly Property Name() As String Get
Return CType(Me("name"), String)
End Get
End Property
End Class

D
Public Class Role

Question:
You are developing a method to encrypt sensitive data with the Data Encryption Standard (DES) algorithm. Your method accepts the following parameters:
The byte array to be encrypted, which is named message
An encryption key, which is named key
An initialization vector, which is named iv
You need to encrypt the data. You also need to write the encrypted data to a MemoryStream object.
Which code segment should you use?
A
DES= des = gcnew DESCryptoServiceProvider();
des->BlockSize = message->Length;
ICryptoTransform= crypto = des->CreateEncryptor(key, iv); MemoryStream =cipherStream = gcnew MemoryStream();
CryptoStream =cryptoStream = gcnew CryptoStream(cipherStream,crypto, CryptoStreamMode::Write);
cryptoStream->Write(message, 0, message->Length);

B
DES =des = gcnew DESCryptoServiceProvider();
ICryptoTransform =crypto = des->CreateEncryptor(key, iv); MemoryStream =cipherStream = gcnew MemoryStream();
CryptoStream =cryptoStream = gcnew CryptoStream(cipherStream, crypto, CryptoStreamMode::Write);
cryptoStream->Write(message, 0, message->Length);

C
DES =des = gcnew DESCryptoServiceProvider();
ICryptoTransform= crypto = des->CreateEncryptor();
MemoryStream =cipherStream = gcnew MemoryStream();
CryptoStream =cryptoStream = gcnew CryptoStream(cipherStream, crypto, CryptoStreamMode::Write);
cryptoStream->Write(message, 0, message->Length);

D
DES =des = gcnew DESCryptoServiceProvider();
ICryptoTransform =crypto = des->CreateDecryptor(key, iv); MemoryStream =cipherStream = gcnew MemoryStream();
CryptoStream =cryptoStream = gcnew CryptoStream(cipherStream, crypto, CryptoStreamMode::Write);
cryptoStream->Write(message, 0, message->Length);

Question: You are loading a new assembly into an application. You need to override the default evidence for the assembly. You require the common language runtime (CLR) to grant the assembly a permission set, as if the assembly were loaded from the local intranet zone. You need to build the evidence collection. Which code segment should you use?
A
Evidence evidence = new Evidence();
evidence.AddHost(new Zone(SecurityZone.Intranet));

B
Evidence evidence = new Evidence(
AppDomain.CurrentDomain.Evidence
);

C
Evidence evidence = new Evidence();
evidence.AddAssembly(new Zone(SecurityZone.Intranet));

D
Evidence evidence = new Evidence(
Assembly.GetExecutingAssembly().Evidence );

File.SetAccessControl("mydata.xml", security);

B
FileSecurity security = new FileSecurity();
security.SetAccessRuleProtection(true, true);
File.SetAccessControl("mydata.xml", security);

C
FileSecurity security = File.GetAccessControl("mydata.xml"); security.SetAccessRuleProtection(true, true);

// Output the region information...
}

B
foreach (CultureInfo culture in CultureInfo.GetCultures(CultureTypes.SpecificCultures)) {

Question:
You write a class named Employee that includes the following code segment.
public ref class Employee
{
String= employeeId;
String= employeeName;
String= jobTitleName;
public:
String= GetName() { return employeeName; }
String= GetJobTitle() { return jobTitleName; }
You need to expose this class to COM in a type library. The COM interface must also facilitate forward-compatibility across new versions of the Employee class.
You need to choose a method for generating the COM interface.
What should you do?
A
Add the following attribute to the class definition.
[ClassInterface(ClassInterfaceType::AutoDual)]
public class Employee {

B
Add the following attribute to the class definition.
[ComVisible(true)]
public class Employee {

C
Add the following attribute to the class definition.
[ClassInterface(ClassInterfaceType::None)]
public class Employee {

D
Define an interface for the class and add the following attribute to the class definition.
[ClassInterface(ClassInterfaceType::None)]
public class Employee : IEmployee {

Question:
You are using the Microsoft Visual Studio 2005 IDE to examine the output of a method that returns a string. You assign the output of the method to a string variable named fName.
You need to write a code segment that prints the following on a single line
The message: "Test Failed: "
The value of fName if the value of fName does not equal "John"
You also need to ensure that the code segment simultaneously facilitates uninterrupted execution of the application.
Which code segment should you use?
A
Debug::WriteLineIf(fName != "John", fName, "Test Failed");

B
Debug::Assert(fName == "John", "Test Failed: ", fName);

C
if (fName != "John") {
Debug::Print("Test Failed: ");
Debug::Print(fName);
}

D
if (fName != "John") {
Debug::WriteLine("Test Failed: ");
Debug::WriteLine(fName);
}
