QUESTION 1
You create a .NET Remoting object named Patientinfo that exposes medical patient information.
Because of the confidential nature of the information, you must ensure that the data remains secure.
You want client applications to connect to Patientinfo over a secure communication channel. You
want to accomplish this task by writing the minimum amount of code.

Actualtests.org – The Power of Knowing
What should you do?
A. Create your own host application and use a TcpChannel and BinaryFormatter.
B. Create your own host application and use an HttpChannel and a SoapFormatter.
C. Install Patientinfo in an Internet Information Services (IIS) virtual directory.
Configure Patientinfo to use a TcpChannel and a BinaryFormatter.
Configure IIS to use SSL.
D. Install Patientinfo in an Internet Information Services (IIS) virtual directory.
Configure Patientinfo to use an HttpChannel and a SoapFormatter.
Configure IIS to use SSL.
Answer: D
Explanation: To minimize the coding we use IIS to deploy the .NET Remoting Object. We then use SSL to
encrypt the HTTP traffic.
Reference: SSL in WinHTTP
Incorrect Answers
A, B: Creating your own host application would require more coding.
C: SSL encrypts HTTP traffic, not TCP traffic.
QUESTION 2
You are creating an XML Web service that will be accessed by callers who cannot use SSL encryption
because if firewall restrictions. To protect sensitive data, you want to encrypt a portion of the data
returned from the service by using objects in the Cryptography namespace.
The service will use a standard encryption routine to encrypt the data before it is sent to the caller.
The caller will decrypt the data by using instructions provided by you.
You need to write code to encrypt the sensitive data that is in a local variable named myData. First,
you create an instance of a Cryptography Service Provider.
What should you do next?
A. Create an Encryptor object that passes in a key and an initialization vector (IV) as parameters.
Call the GetHashCode method of the Encryptor object to generate a new hash code.
Convert the generated hash code to a stream and use the CryptoStream object to write the value of
the hash code to an encrypted stream.
Convert the output stream to a string.
B. Create a UnicodeEncoding object and use it to encode the value of myData into a byte array.
Use the ComputeHash method of the Cryptography Service Provider to create a hash from the
encoded byte array.
Convert the output of ComputeHash from a byte array to a string.
C. Create a UnicodeEncoding object and use it to encode the value of myData into a byte array.
Use the GetHashCode method of the Cryptography Service Provider to create a hash from the
encoded byte array.
Convert the output of GetHashCode from a byte array to a string.
D. Create an Encryptor object that passes in a key and an initialization vector (IV) as parameters.
Create a CryptoStream object that passes in an output stream and the Encryptor object as parameters.

Convert myData to a stream and use the CryptoStream object to write the value of myData to an
encrypted stream.
Convert the output stream to a string.
Answer: D
Explanation: The common language runtime uses a stream-oriented design for cryptography. The core of
this design is CryptoStream.
The SymmetricAlgorithm.CreateEncryptor Method creates a symmetric encryptor object with the current
Key and initialization vector (IV). We then use this encryptor object and pass it to stream. The stream will
then be encrypted. The value of myDate can be written to the encrypted stream by the send, and the receiver
can retrieve it and decrypt it to a string.
Incorrect Answers
A: The Encryptor object will be required when setting up the CryptoStream. We cannot use a hash code
of the Encryptor object.
B, C: UniEncoding is used to convert characters between the Unicode and ASCII standards. UniEncoding
is not used for encryption.

QUESTION 3
You are developing a Windows-based application that requires the use of a calculation function
named CalculateValue. This function includes the following signature:
int CalculateValue(int x) ;
CalculateValue is located in an unmanaged DLL named Certkiller Functions.dll, and is not part of a
COM interface. You need to be able to use CalculateValue in your application.
Which action or actions should you take? (Choose all that apply)
A. Use Regsvr32.exe to register Certkiller Functions.dll.
B. Use Visual Studio .NET to add a reference to Certkiller Functions.dll.
C. To your application, add the following code segment:
using Certkiller Functions;
D. To your application, add the following code segment:
[DllImport(" Certkiller Functions.dll")]
public static extern int CalculateValue(int x);
Answer: D
Explanation:
We must identify the function we want to use in the unmanaged dll. The only necessary step is add the code
in D.
Incorrect Answers

Actualtests.org – The Power of Knowing
A: Regsrv32 is not required in Visual Studio .NET. Regsrv32 was used for Visual Basic 6.0, and for
Visual C++ 6.0 components.
B:: CalculateValue is in an unmanaged DLL which is not part of a COM interface. So, you don’t have to
add any reference to Certkiller Functions.dll.
Note: In Visual Studio .NET IDE you make references to .NET Components, COM components and
to other projects, not to Windows native DLLs.
C: We are not using the NameSpace of the unmanaged dll.
