Figure out the parameters those need be correlated in Documentum Application

  1. ClientId

  2. jsessionid

  3. Formclass

  4. FormId

  5. ReqID

  6. Reload
Reveal answer Fill a bubble to check yourself
A,B,E,F Correct answer
Explanation

In Documentum web applications, dynamic session and request identifiers like ClientId, jsessionid, ReqID, and Reload change with each request or session and must be correlated in LoadRunner to maintain a valid session. Formclass and FormId are typically static application-level identifiers and do not require correlation.

Which portocol is used for recording Webtop(A Documentum Aplication by EMC) in Loadrunner?

  1. SAP-Web

  2. Web(HTTP/HTML)

  3. Web(Click and Script)

  4. Web Services
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Webtop is a web-based application that runs over HTTP/HTTPS. LoadRunner's 'Web (HTTP/HTML)' protocol is designed to record and replay web browser traffic by capturing the underlying HTTP requests, which is the correct protocol for testing Documentum's web interface.

An _________ is a special kind of Java program that is designed to be transmitted over the Internet.

  1. Viewlet

  2. Applet

  3. Servlet

  4. Object
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

An Applet is a specialized Java program designed to run within web browsers, transmitted over the Internet and executed client-side. Unlike Servlets which run server-side, Applets provided early web interactivity before modern JavaScript frameworks emerged.

  3. Silver Light

  4. Dot net
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Projectserver.nielsen.com uses Dot Net (Microsoft .NET) technology. This is consistent with Microsoft-based enterprise project management systems. Flex (A) and Silverlight (C) are RIA frameworks, not backend server technologies. JSP (B) is Java-based, while .NET is Microsoft's framework.

Primary benefits of wicket framework are__.

  1. Clean separation of concerns between HTML and Java

  2. Automated state management

  3. conjunction with JSP and custom tag libraries

  4. Abstraction away from Servlet API and HTTP protocol details
Reveal answer Fill a bubble to check yourself
A,B,D Correct answer
Explanation

Wicket's key benefits are: clean HTML/Java separation (pages are pure XHTML with minimal Wicket tags), automated state management (no manual HTTP session handling), and abstraction from Servlet/HTTP protocol details (developers work with Java components, not HTTP requests directly). Option C describes JSP/taglibs, which Wicket specifically avoids.

Select appropriate reasons those make struts framework outdated.

  1. It is not particularly object-oriented.

  2. You work with hierarchies of components and design your application as such.

  3. Unless you output HTML directly from your Java code you still need to learn another major technology JSP plus custom tag libraries in order to produce output HTML pages.

  4. A very clean object-oriented and component based approach.
Reveal answer Fill a bubble to check yourself
A,C Correct answer
Explanation

Struts is considered outdated because: (A) it's not truly object-oriented - Action classes are HTTP-driven rather than OO-designed; (C) it requires learning JSP and custom taglibs for HTML output. Options B and D incorrectly describe Struts - B mentions hierarchies (not a Struts strength) and D claims it's clean OO (which it is not).

Multiple choice technology web technology

Select appropriate answers those solves the main problems with the struts philosophy.

  1. Each Action class defines an abstraction, but the abstraction is determined by the HTTP procotol request mechanism rather than by an object-oriented analysis

  2. Wicket is fully object-oriented. You work with hierarchies of components and design your application as such.

  3. Wicket markup files are as close to pure HTML as it is possible to get. Where Wicket does introduce content into the markup it is very clean and complies with all XHTML standards

  4. Wicket is based around intercepting each HTTP request to a web application and directing it to a specific Action class that handles the request
Reveal answer Fill a bubble to check yourself
B,C Correct answer
Explanation

Wicket solves Struts' problems by: (B) being fully object-oriented with component hierarchies, and (C) using pure HTML markup that complies with XHTML standards. Option A describes Struts' problem (Action classes tied to HTTP), and D describes Struts' architecture (not Wicket's).

With wicket,we can get benefits of which technology even when you are using just java and just HTML.

  1. JSP

  2. Servlets

  3. Ajax

  4. Applet
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

With Apache Wicket, developers get the benefits of Ajax functionality (partial page updates, dynamic content refresh) without writing raw JavaScript code. Wicket's Ajax-enabled components handle all the complex Ajax plumbing behind the scenes while you work with just Java and HTML. The correct answer is Ajax.

A project on which you are working calls for you to store small amount of frequntly changing information about a page on the client. For this project, SECURITY is not worried. Which method is thebest method to use

  1. Cookies

  2. A query String

  3. A URL

  4. A javascript function

  5. A hidden form field
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

Hidden form fields are ideal for storing small amounts of frequently changing page-specific data when security isn't a concern, as they persist with the page and form without the size limitations of cookies or URL complexity. Cookies have size limits (~4KB) and are sent with every HTTP request, while query strings and URLs are visible in the address bar and limited in length.

How does ASP.NET stores SessionID's default?

  1. In Cache

  2. In Cookies

  3. In A Global Variable

  4. In URL
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

ASP.NET stores SessionIDs in cookies by default, using a non-persistent cookie named ASP.NET_SessionId that identifies the user session across requests. The SessionID can be stored in the URL if cookieless sessions are configured, but cookies are the standard default mechanism.
