Question 2

________ architecture separates application's from the graphical presentation and the processing logic.&#10;A) Data-Presentation-Logic.&#10;B) Data-View-Controller.&#10;C) Model-View-Controller.&#10;D) None of the above.

Accepted Answer

Model-View-Controller (MVC) architecture separates an application into three interconnected components: the model, the view, and the controller. The model represents the application's data and business logic, the view displays data to the user, and the controller handles user input and updates the model and view accordingly. This separation allows for greater flexibility and modularity in the development and maintenance of software applications. The other options listed, Data-Presentation-Logic and Data-View-Controller, are not commonly used software architecture patterns.

Question 3

________ are instances of classes that follow certain conventions for class design.&#10;A) Properties.&#10;B) JavaBeans objects.&#10;C) JSF elements.&#10;D) None of the above.

Accepted Answer

JavaBeans objects are instances of classes that follow certain conventions for class design, such as having a default constructor, having getter and setter methods for properties, and implementing the Serializable interface. Properties (A) and JSF elements (C) are not necessarily defined by conventions for class design.

Question 4

Which of the following is true?&#10;A) An @RequestScoped bean can be access by all of an app's pages during a session.&#10;B) Sessions never expire.&#10;C) An @SessionScoped is created when a session begins and exists throughout the entire session.&#10;D) None of the above.

Accepted Answer

An @RequestScoped bean is only accessible during a single request, while an @SessionScoped bean is created when a session begins and exists throughout the entire session. Sessions can expire after a predetermined period of inactivity, so option B is not true.

Question 5

Tracking individual clients as they visit a website is known as ________.&#10;A) session tracking.&#10;B) client tracking.&#10;C) personalization.&#10;D) None of the above.

Accepted Answer

Session tracking is the process of keeping track of a user's activity on a website during a single visit, which may include actions such as clicking links or adding items to a shopping cart. It is used to provide personalized experiences for users, such as remembering their preferences or displaying relevant content based on their past behavior. Client tracking and personalization are related concepts, but they do not specifically refer to tracking individual clients during a single visit to a website.

Question 6

A ________ determines whether a field contains an acceptable number of characters.&#10;A) f:validateDoubleRange.&#10;B) f:validateLength.&#10;C) f:validateLongRange.&#10;D) None of the above.

Accepted Answer

The f:validateLength tag is used to validate whether a field contains an acceptable number of characters. The tag can be used to specify the minimum and maximum number of characters that are acceptable for a field. The f:validateDoubleRange tag is used to validate whether a field contains a value within a specified range. The f:validateLongRange tag is used to validate the value of an integer field within a specified range.

Question 7

Which of the following is true?&#10;A) An app's images and CSS files can be placed in any folder of the app.&#10;B) An app's images and CSS files are placed in the app's resources folder within the Web Pages node.&#10;C) An app's images and CSS files are placed in the subfolders of the app's resources folder within the Web Pages node.&#10;D) None of the above.

Accepted Answer

Images and CSS files are typically organized within subfolders of the app's resources folder located within the Web Pages node to maintain a structured and organized file system, facilitating easier management and referencing of these resources in the app's development.

Question 8

A JavaBean exposes its data to a JSF document as ________.&#10;A) Properties.&#10;B) JavaBeans objects.&#10;C) JSF elements.&#10;D) None of the above.

Accepted Answer

JavaBean objects expose their data to a JSF document as properties. These properties can then be accessed and manipulated within the JSF document using standard JSF expressions.

Question 9

Which of the following is true?&#10;A) When you invoke a JSF app from a web browser for the first time, the browser requests the app's default JSF page.&#10;B) When a web server receives a request for a JSF app, it passes the request to the JSF web-application framework for processing.&#10;C) The JSF framework includes the Faces servlet-a software component running on the server that processes each requested JSF page so that the server can eventually return a response to the client.&#10;D) All of the above.

Accepted Answer

A) This is true as the browser needs to request the default JSF page in order to access the app.
B) This is also true as the web server delegates the processing of JSF requests to the JSF framework.
C) This is true as the Faces servlet is a key component of the JSF framework that is responsible for processing each requested page and generating a corresponding response.

Therefore, all of the statements are true, making D the correct answer.

Accepted Answer

The user interface tier, business logic tier, and information tier are the most common and traditional tiers in a web application architecture. The user interface tier is responsible for the presentation layer, the business logic tier is responsible for the data processing and logic, and the information tier is responsible for data storage and retrieval. Option B is incorrect as it refers to a browser tier which is not a typical tier in a web application, Option C is incorrect as it refers to different names for the three tiers.
