In order to be able to locate the error, you have to track each change that is made to a user profile by raising a custom event.
In the options below, which event should you use?

• A. You should use WebRequestEvent
• B. You should use WebAuditEvent

You work as the developer in an IT company. Recently your company has a big customer. The customer runs a large supermarket chain. You're appointed to provide technical support for the customer. Now you are creating an application. No body can run the application except members of the Administrator group are allowed to run it by using the credentials of the end user. You protect sensitive data within the application by writing the following security code.
bool isAdmin = false;
WindowsBuiltInRole role = WindowsBuiltInRole.Administrator;
...
if (!isAdmin)
throw new Exception("User not permitted");
In order to make sure that if a user who is not a member of the Administrator group runs the apllication, the application throws an exception, a code segment should be added to this security code.
In the options below, which code segment should you use?

• A. WindowsIdentity currentUser = WindowsIdentity.GetCurrent();foreach (IdentityReference grp in currentUser.Groups) { NTAccount grpAccount = ((NTAccount)grp.Translate(typeof(NTAccount))); isAdmin = grp.Value.Equals(role); if (isAdmin) break;}
• B. WindowsPrincipal currentUser = (WindowsPrincipal)Thread.CurrentPrincipal;isAdmin = currentUser.IsInRole(role);
• C. GenericPrincipal currentUser = (GenericPrincipal) Thread.CurrentPrincipal;isAdmin = currentUser.IsInRole(role.ToString());
• D. WindowsIdentity currentUser = (WindowsIdentity)Thread.CurrentPrincipal.Identity;isAdmin = currentUser.Name.EndsWith("Administrator");

You have just graduated from college, now you are serving the internship as the software developer in an international company. According to the requirements of the company CIO, you're developing a server. You are developing a method to hash data with the Secure Hash Algorithm. The data is passed to your method as a byte array named message. You have to use SHA1 to compute the hash of the incoming parameter. Besides this, you have to place the result into a byte array named hash. In the options below, which code segment should you use?

• A. Dim objSHA As New SHA1CryptoServiceProviderDim hash() As Byte = objSHA.ComputeHash(message)
• B. Dim objSHA As New SHA1CryptoServiceProviderobjSHA.GetHashCode()Dim hash() As Byte = objSHA.Hash
• C. Dim objSHA As New SHA1CryptoServiceProviderDim hash() As Byte = NothingobjSHTransformBlock(message, 0, message.Length, hash, 0)
• D. Dim objSHA As New SHA1CryptoServiceProviderDim hash() As Byte = BitConverter.GetBytes(objSHA.GetHashCode)

You have just graduated from college, now you are serving the internship as the software developer in an international company. According to the requirements of the company CIO, you are creating a class which contains a method named GetCurrentRate. The GetCurrentRate method retrieves the current interest rate and a variable named currRate that stores the current interest rate. You write serialized representations of the class. You have to write a code segment, when an instance of the class is deserialized, the segment updates the currRate variable with the current interest rate. So what code segment should you write?

• A. <OnSerializing> _Friend Sub UpdateValue (ByVal context As StreamingContext) currRate = GetCurrentRate()End Sub
• B. <OnSerializing> _ Friend Sub UpdateValue(ByVal info As SerializationInfo) info.AddValue("currentRate", GetCurrentRate())End Sub
• C. <OnDeserializing> _ Friend Sub UpdateValue(ByVal info As SerializationInfo) info.AddValue("currentRate", GetCurrentRate())End Sub
• D. <OnDeserialized> _Friend Sub UpdateValue (ByVal context As StreamingContext) currRate = GetCurrentRate()End Sub
