QUESTION 1
You work as an application developer at Certkiller .com. Certkiller .com has asked
you to create an application that copies file content from one file on a client
computer named Certkiller -WS007 to a new file on a server named
Certkiller -SR15.
The method displayed in the following exhibit is included in the new application:
You have to ensure that the application copies all permissions on the original file to
the new file. You should also make sure that the new file does not inherit its
permissions from the destination directory on Certkiller -SR15.
What should you do?
A. Add the following code to the Copy method:
file2.SetAccessControl (file1.GetAccessControl ());
B. Add the following code to the Copy method:
FileSecurity acl = file1.GetAccessControl ();
acl. SetAccessRuleProtection (true, true);
file2.SetAccessControl (acl);
C. Add the following code to the Copy method:
file2.SetAccessControl (file1.GetAccessControl (), false);
D. Add the following code to the Copy method:
FileSecurity acl = file1.GetAccessControl ();
acl. SetAccessRuleProtection (true, false);
file2.SetAccessControl (acl);
Answer: B
Explanation: This code retrieves the FileSecurity object from the original file, copies

Actualtests.org – The Power of Knowing
and protects the ACL settings from directory inheritance, and copies the ACL
settings to the destination file. The GetAccessControl method returns a FileSecurity
object representing the ACL of the original file. The SetAccessRuleProtection
method sets or removes ACL protection from the parent objects through
inheritance. The SetAccessRuleProtection method accepts two Boolean arguments,
the first of which indicates whether settings are protected from inheritance, and the
second of which indicates whether to preserve the existing inherited access rule. In
this scenario, the value true for both arguments indicates that the ACL is protected
from inheritance, but the current ACL settings are copied. The SetAccessControl
method takes a FileSecurity object and applies the ACL to the destination folder.
Incorrect Answers:
A, C: You should not use the code fragments that do not invoke the
SetAccessRuleProtection method because this will not protect the destination file’s ACL
settings from inheritance.
D: This code will protect the ACL from inheritance, but it does not copy the existing
inherited ACL settings.
QUESTION 2
You work as an application developer at Certkiller .com. Certkiller .com has been
contracted by a local doctor’s clinic to develop a client application using Microsoft
.NET 2.0 that sends patient visit information to a remote server at the clinic’s main
office.
This data must be transmitted via a secure network stream because it contains
patient protected health information (PHI). The data will be sent from a windows
application client on the doctor’s notebook computer to a windows service hosted on
a remote server. Both of these applications employ a certificate store for network
identification.
You need to create a secure data stream by adding certain classes to the client
application.
What classes should you add? (Choose three)
A. The MD5CryptoServiceProvider class.
B. The X509Certificate class.
C. The NetworkStream class.
D. The SslStream class.
E. The TcpListener class.
F. The TcpClient class.
Answer: B, D, F
Explanation: You should use the X509Certificateclass to store the server certificate
and encrypt data, the SslStream class to create a secure channel, and the TcpClient
class to establish the connection with the server application.
Incorrect Answers:
A: Using this option would only hash the data using the MD5 algorithm.

C: Using this option would not necessarily create a secure channel.
E: This class is used by the server application.
QUESTION 3
You work as an application developer at Certkiller .com. Certkiller .com has been
contracted by the local hospital to create an application that forwards private
patient information to various insurance providers.
The hospital informs you that the amount and frequency of the patient data is high.
You need to ensure that data confidentiality is guaranteed, with as little overhead as
possible.
You now need to encrypt the patient information.
What should you do?
A. Use the following code:
public byte [] EncryptData (byte [] PatientInfo, RSACryptoServiceProvider SecretKey)
{
CryptoSream cs = new CryptoSream (SecretKey);
cs.Encrypt (PatientInfo, 0, PatientInfo.Length);
byte [] data = cs.ToArray ();
cs.Close ();
return data;
}
B. Use the following code:
public byte [] EncryptData (byte [] PatientInfo, RSACryptoServiceProvider SecretKey)
{
MemorySream ms = new MemorySream ();
CryptoSream cs = new CryptoSream (ms, SecretKey.CreateEncryptor (),
CryptoSreamMode.Write);
cs.Write (PatientInfo, 0, PatientInfo.Length);
cs.Close ();
byte [] data = ms.ToArray ();
ms.Close ();
return data;
}
C. Use the following code:
public byte [] EncryptData (byte [] PatientInfo, DESCryptoServiceProvider SecretKey)
{
CryptoSream cs = new CryptoSream (SecretKey);
cs.Encrypt (PatientInfo, 0, PatientInfo.Length);
byte [] data = cs.ToArray ();
cs.Close ();
return data;
}
D. Use the following code:
public byte [] EncryptData (byte [] PatientInfo, DESCryptoServiceProvider SecretKey)
{

Actualtests.org – The Power of Knowing
MemorySream ms = new MemorySream ();
CryptoSream cs = new CryptoSream (ms, SecretKey.CreateEncryptor (),
CryptoSreamMode.Write);
cs.Write (PatientInfo, 0, PatientInfo.Length);
cs.Close ();
byte [] data = ms.ToArray ();
ms.Close ();
return data;
}
Answer: D
Explanation: This code instantiates a CryptoStream object, specifies the
ICryptoTransform object to encrypt data, encrypts the PatientInfo byte array, and
returns the encrypted byte array. The DESCryptoServiceProvider class represents
a managed cryptographic provider of the DataEncryption Standard (DES)
symmetric algorithm. The DES symmetric algorithm is commonly used for dat
confidentiality, and it supports 64-bit keys. When you instantiate a
DESCryptoServiceProvider object, a secret key for encryption and an initialization
vector (IV) are created. Because the same key and IV are needed for encryption and
decryption, the CreateEncryptor and CreateDecryptor methods generate the
appropriate ICryptoTransform object to alter the data.
Incorrect Answers:
A, B: You should not use the code fragments that specify the
RSACryptoServiceProvider because this implements an asymmetric algorithm.
C: You should not use the code fragments that invoke the Encrypt method because
no such method exists in the CryptoSream class.
