Microsoft 98-372 Online Questions & Answers

• Question 41:

  What is the characteristic of a delegate?

  A. A type-safe function pointer
  B. An object that raises an event
  C. A tightly coupled event
  D. A property function that includes optional parameters
  A. A type-safe function pointer

  ---

  The .NET Framework defines a special type (Delegate) that provides the functionality of a function pointer.

  A delegate is a class that can hold a reference to a method. Unlike other classes, a delegate class has a signature, and it can hold references only to methods that match its signature. A delegate is thus equivalent to a type-safe function pointer or a callback.

• Question 42:

  Custom event delegates are used to:

  A. Raise one or more custom events
  B. Handle errors generated in a try block.
  C. Route events to one or more event handlers.
  D. Process mouse clicks or keyboard input.
  C. Route events to one or more event handlers.

• Question 43:

  Connection strings in the web.config file are:

  A. Automatically encrypted when the project is published.
  B. Automatically encrypted by the web server.
  C. Stored in binary format.
  D. Stored in clear text unless they are encrypted.
  D. Stored in clear text unless they are encrypted.

  When working with data source controls it is recommended that you centralize the location of your connection strings by storing them in the application's Web.config file. This simplifies the management of connection strings by making them available to all of the ASP.NET pages in a Web application. In addition, you do not need to modify numerous individual pages if your connection string information changes. Finally, you can improve the security of sensitive information stored in a connection string, such as the database name, user name, password, and so on, by encrypting the connection string section of the Web.config file using protected configuration.

• Question 44:

  Which two methods can you use to load an assembly? (Each correct answer presents a complete solu- tion. Choose two.)

  A. GetLoadedModules()
  B. LoadModule(String, ByteQ)
  C. LoadFrom(String)
  D. Load(String)
  B. LoadModule(String, ByteQ)
  D. Load(String)

  ---

  B: LoadModule(String, Byte[])

  Loads the module, internal to this assembly, with a common object file format (COFF)-based image containing an emitted module, or a resource file.

  D: Assembly.Load Method (String)

  Loads an assembly given the long form of its name.

  C. Console.WriteLine("Hello")
  D. Console.Write("Hello\t")
  E. Console.Error.WriteLine("Hello")
  A. Console.Write("Hello\n")
  C. Console.WriteLine("Hello")
