Question No: 73 – (Topic 1)
You create an unmanaged object and use the object. You no longer need the object. What should you do?
-
Set the value of the variable to null.
-
Cache the variable#39;s value in a static variable.
-
Dispose the object to release memory.
-
Cast the object to its base type.
Answer: C
Explanation: The term quot;unmanaged resourcequot; 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 non-.net resources on the client machine, if the provider isn#39;t written entirely in managed code.
This is why, for something like a database connection, it#39;s recommended you write your code thusly:
using (var connection = new SqlConnection(quot;connection_string_herequot;))
{
// Code to use connection here
}
As this ensures that .Dispose() is called on the connection object, ensuring that any unmanaged resources are cleaned up.
Question No: 74 – (Topic 1)
What is the characteristic of a delegate?
-
A type-safe function pointer
-
An object that raises an event
-
A tightly coupled event
-
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.
Question No: 75 – (Topic 1)
Where are the command line arguments stored for a console application?
-
In a value-type parameter that is passed to the Main method.
-
In the Console.In property.
-
In a string array parameter that is passed to the Main method.
-
In the Console.Read() method.
Answer: C
Question No: 76 – (Topic 1)
What is the purpose of the app.config file?
-
To configure the version of .NET targeted by the application.
-
To load references to third-party libraries used by the application.
-
To find out the programming language of the application.
-
To configure the target operating system of the application.
Answer: A
Question No: 77 – (Topic 1)
You create a class library named Contoso.Business. The library is used in a Windows application named Contoso.Ui.
In which file should you store application configuration settings during deployment?
-
Web.config
-
Machine.config
-
Contoso.Ui.config
-
Contoso.Business.config
Answer: C
Explanation: The project system stores application settings in two XML files: an app.config file, which is created at design time when you create the first application setting; and a user.config file, which is created at run time when the user who runs the application changes the value of any user setting.
Question No: 78 – (Topic 1)

Question No: 79 – (Topic 1)
Which describes an interface?
-
Allows managed code to access unmanaged code.
-
Contains code that implements properties, methods, and events.

A template that defines a set of properties, methods, and events.
-

Answer: C
Question No: 80 – (Topic 1)
Connection strings in the web.config file are:
-
Automatically encrypted when the project is published.
-
Automatically encrypted by the web server.
-
Stored in binary format.
-
Stored in clear text unless they are encrypted.
Answer: D
Explanation: When working with data source controls it is recommended that you centralize the location of your connection strings by storing them in the application#39;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.
