You are writing a method to compress an array of bytes. The array is passed to the method in a parameter named document. You need to compress the incoming array of bytes and return the result as an array of bytes. Which code segment should you use?

You create a class library that contains the class hierarchy defined in the following code segment. (Line numbers are included for reference only.)

01 public class Group {
02 public Employee[] Employees;
03 }
04 public class Employee {
05 public string Name;
06 }
07 public class Manager : Employee {
08 public int Level;
09 }
You create an instance of the Group class. You populate the fields of the instance. When you attempt to serialize the instance by using the Serialize method of the XmlSerializer class, you receive InvalidOperationException. You also receive the following error message: “There was an error generating the XML document.” You need to modify the code segment so that you can successfully serialize instances of the Group class by using the XmlSerializer class. You also need to ensure that the XML output contains an element for all public fields in the class hierarchy. What should you do?

You create an application for your business partners to submit purchase orders. The application deserializes XML documents sent by your partners into instances of an object named PurchaseOrder. You need to modify the application so that it collects details if the deserialization process encounters any XML content that fails to map to public members of the PurchaseOrder object.
What should you do?

You are creating a class that performs complex financial calculations. The class contains a method named GetCurrentRate that retrieves the current interest rate and a variable named currRate that stores the current interest rate. You write serialized representations of the class. You need to write a code segment that updates the currRate variable with the current interest rate when an instance of the class is deserialized. Which code segment should you use?

You are writing a method to compress an array of bytes. The bytes to be compressed are passed to the method in a parameter named document. You need to compress the
contents of the incoming parameter. Which code segment should you use?

You are developing an application that will use custom authentication and role-based security. You need to write a code segment to make the runtime assign an unauthenticated principal object to each running thread. Which code segment should you use?

You create Web-based client applications. The application permits users to upload files to a network share. When anonymous users use the upload feature from the Web-based application, a custom error page is displayed. You need to ensure that anonymous users are able to use the application. What should you do?

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?

You create Web-based client applications. You are creating an ASP.NET intranet site. The site permits individual departments to post content without involving the Central Information Technology resources. The site also permits Central Information Technology to maintain control over the intranet as a whole. Each department wants complete control over the appearance and behavior of their departmental content. However, Information Technology directives require every page on the intranet to maintain a consistent appearance and behavior. You need to develop the Web page on the intranet site so that it meets the requirements. What should you do?

You create Web-based client applications. You create an application that will be used by customers to browse the product catalog of an Internet-based store and buy products.

The application must meet the following requirements:

Permit registered customers of the store to change display settings and personal information. Store the updated information and associate the information with the logged-on customer.

You need to choose appropriate technologies to meet these requirements. Which two technologies should you choose? (Each correct answer presents part of the solution. Choose two.)
