Question 1

Ajax allows your client-side web pages to exchange data with the server through asynchronous calls.

Accepted Answer

Ajax (Asynchronous JavaScript and XML) enables web applications to send and retrieve data from a server asynchronously without interfering with the display and behavior of the existing page.

Question 2

To avoid full postbacks and update only part of the page, you can use the _______ server control.&#10;A) AjaxMaster&#10;B) UpdatePanel&#10;C) PartialPostback&#10;D) None of the above

Accepted Answer

The UpdatePanel server control is used in ASP.NET applications to enable partial-page updates. It allows for sections of a page to be updated without requiring a full page postback, making the user experience smoother and more responsive.

Question 3

The ScriptManager control can only be placed directly on the page, NOT in the master page for the site.

Accepted Answer

The ScriptManager control can be placed on a master page, allowing all content pages that use the master page to access the functionality provided by the ScriptManager, such as enabling AJAX features across the site.

Question 4

The _________ control can be used to execute server side code repeatedly.&#10;A) Tick&#10;B) Clock&#10;C) Execution&#10;D) None of the above

Accepted Answer

The question seems to be based on a misunderstanding or misrepresentation of how server-side code execution controls work in web development. There is no standard control named Tick, Clock, or Execution specifically designed to execute server-side code repeatedly in the manner the question suggests. Server-side code execution is typically managed through programming logic, not through a singular control or component with such names.

Question 5

Web Services are methods that you can call over the internet and that can optionally return data.

Accepted Answer

Web Services are designed to enable communication between different systems over the internet, allowing methods to be called remotely, often with the ability to return data as a response.

Question 6

Page Methods can be called over the web as well as from a script running directly on the same page.

Accepted Answer

Page Methods are specifically designed to be called from client-side scripts, such as JavaScript, using AJAX. They are not intended to be called over the web like web services or APIs.
