NEW QUESTION 1

You have a Microsoft ASP.NET web application.
You need to store a value that can be shared across users on the server. Which type of state management should you use?

• A. Session
• B. ViewState
• C. Application
• D. Cookies

Answer: C

Explanation:
Application state is a data repository available to all classes in an ASP.NET application. Application state is stored in memory on the server and is faster than storing and retrieving information in a database. Unlike session state, which is specific to a single user session, application state applies to all users and sessions. Therefore, application state is a useful place to store small amounts of often-used data that does not change from one user to another.
Incorrect:
not A: Session State contains information that is pertaining to a specific session (by a particular client/browser/machine) with the server. It's a way to track what the user is doing on the site.. across multiple pages...amid the statelessness of the Web. e.g. the contents of a particular user's shopping cart is session data. Cookies can be used for session state. Not B: Viewstate is a state management technique in asp.net. ASP.NET Viewstate is preserving the data between the requests or postbacks and stored in hidden fields on the page.

NEW QUESTION 3

You need to allow a consumer of a class to modify a private data member. What should you do?

• A. Assign a value directly to the data member.
• B. Provide a private function that assigns a value to the data member.
• C. Provide a public function that assigns a value to the data member.
• D. Create global variables in the class.

Answer: C

Explanation:
In this example (see below), the Employee class contains two private data members, name and salary. As private members, they cannot be accessed except by member methods. Public methods named GetName and Salary are added to allow controlled access to the private members. The name member is accessed by way of a public method, and the salary member is accessed by way of a public read-only property.
Note: The private keyword is a member access modifier. Private access is the least permissive access level. Private members are accessible only within the body of the class or the struct in which they are declared
Example:
class Employee2
{
private string name = "FirstName, LastName"; private double salary = 100.0;
public string GetName()
{
return name;
}
public double Salary
{
get { return salary; }
}
}

You create an application that uses Simple Object Access Protocol (SOAP).
Which technology provides information about the application's functionality to other applications?

• A. Web Service Description Language (WSDL)
• B. Extensible Application Markup Language (XAML)
• C. Common Intermediate Language (CIL)
• D. Universal Description, Discovery, and Integration (UDDI)

Answer: A

Explanation:
WSDL is often used in combination with SOAP and an XML Schema to provide Web services over the Internet. A client program connecting to a Web service can read the WSDL file to determine what operations are available on the server. Any special datatypes used are embedded in the WSDL file in the form of XML Schema. The client can then use SOAP to actually call one of the operations listed in the WSDL file using for example XML over HTTP.

* A language mechanism for restricting access to some of the object's components.
* A language construct that facilitates the bundling of data with the methods (or other functions) operating on that data.
