  • A. ASP.NET IIS Registration Tool (RegIIS.exe)
  • B. Intermediate Language Disassembler (ILDASM.exe)
  • C. Web Site Administration Tool
  • D. Dotfuscator Software Services

Answer : A

Explanation: You can use the ASP.NET IIS Registration Tool (Aspnet_regiis.exe) to encrypt or decrypt sections of a Web configuration file.
The following command encrypts the connectionStrings element in the Web.config file for the application SampleApplication. aspnet_regiis -pe "connectionStrings" -app "/SampleApplication" -prov

Type-safe code accesses only the memory locations:

  • A. It is authorized to access.
  • B. Of objects on the heap.
  • C. Of objects that are static or shared.
  • D. Of objects on the stack.

Answer : A

Which file contains the required .NET settings for an ASP.NET web application?

Answer : B

You create an unmanaged object and use the object. You no longer need the object.
What should you do?

  • A. Set the value of the variable to null.
  • B. Cache the variable's value in a static variable.
  • C. Dispose the object to release memory.
  • D. Cast the object to its base type.

Answer : C

Explanation: The term "unmanaged resource" is usually used to describe something not directly under the control of the garbage collector. For example, if you open a connection to a database server this will use resources on the server (for maintaining the connection) and possibly other resources on the client machine, if the provider isn't written entirely in managed code.
This is why, for something like a database connection, it's recommended you write your code thusly: using (var connection = new SqlConnection("connection_string_here"))
// Code to use connection here
As this ensures that .Dispose() is called on the connection object, ensuring that any unmanaged resources are cleaned up.

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

Answer : A

Explanation: 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.

  • C. In a string array parameter that is passed to the Main method.
  • D. In the Console.Read() method.
