Question 1

The primary way a website personalizes the content presented to a visitor is through the use of:

Accepted Answer

Cookies are small files stored on a visitor's computer that record their activity on a website. This information can then be used to personalize content for the visitor on subsequent visits to the site. Privacy policies, accessibility rules, and site management tools are important for website management, but they do not directly affect content personalization.

Question 2

Django is based on which of the following?

Accepted Answer

Django is based on Python, which is a high-level, interpreted programming language that emphasizes code readability and ease of use. Python is known for its simplicity, versatility, and vast community support. It is a popular choice for building web applications, data science, and machine learning projects. Django has a strong emphasis on the Model-View-Controller (MVC) architecture and is designed to help developers build complex, database-driven web applications quickly and easily.

Question 3

Django follows the ________ programming principle.

Accepted Answer

Django follows the DRY (Don't Repeat Yourself) programming principle which means that it encourages developers to write reusable code as much as possible, avoiding repetition in code. This principle helps in maintaining and updating the code effectively while minimizing the possibility of errors. CoC (Convention over Configuration) is a principle followed by many frameworks, including Ruby on Rails, but not by Django. WYSIWYG (What-You-See-Is-What-You-Get) is a user interface design principle and has no relevance to programming principles. LAMP (Linux, Apache, MySQL, PHP/Perl/Python) is a software stack used for web development and has no connection to Django's programming principles.

What are widgets and how are they used? How do they differ from mashups?

Accepted Answer

The answer of What are widgets and how are they...

Question 6

Which of the following is the most commonly used server-side scripting language?

Accepted Answer

PHP is the most commonly used server-side scripting language which is designed specifically for web development. It is an open-source language and widely used by developers to create dynamic websites and web applications. Ruby on Rails and Django are also server-side scripting languages but they are less commonly used as compared to PHP. Perl is a general-purpose programming language and not specific to web development.

Question 7

____________ is a programming language invented by Netscape used to control the objects on an HTML page and handle interactions with the browser.

Accepted Answer

JavaScript is the programming language used to control objects on an HTML page and handle interactions with the browser. VBScript is a scripting language, but is primarily used for Microsoft applications. ActiveX is a set of technologies primarily used for creating interactive and multimedia content on the web. ColdFusion is a programming language used for web development, but is typically used more for server-side programming rather than client-side interactions with the browser.

Question 8

Accepted Answer

The answer of Storing HTML pages in RAM rather than...

Question 10

Ruby on Rails is based on which of the following philosophies?

Accepted Answer

Ruby on Rails is based on the philosophy of Convention over Configuration (CoC), which means that the framework assumes certain conventions and defaults, reducing the need for configuration and boilerplate code. This approach allows developers to focus on creating application logic rather than spending time configuring the framework. SLDC (Software Development Life Cycle) is a methodology for managing the development of software projects, LAMP (Linux, Apache, MySQL, PHP) is a technology stack, and Ajax is a technique for creating dynamic web applications.

Question 11

Which of the following is a server-side technique that detects the attributes of the device making the request,and using predefined templates,loads a version of a site that is optimized for the device?

Accepted Answer

AWD (Adaptive Web Design) is the server-side technique that detects the attributes of the device making the request and loads a version of the site that is optimized for the device using predefined templates. LAMP (Linux, Apache, MySQL, PHP) is a server-side platform used for web development. Mobile-first design is an approach to web design that prioritizes mobile devices over desktop devices during the design process. RoR (Ruby on Rails) is a web development framework.

Question 12

All of the following are key design principles of responsive web design except:

Accepted Answer

"Coding by convention" is not a key design principle of responsive web design. The other options (flexible grid-based layouts, media queries, and flexible images and media) are key principles of responsive web design.

Question 13

Building which of the following is the most expensive path to creating a mobile presence?

Accepted Answer

Creating a native app is the most expensive option as it requires specific coding languages, tools, and development expertise. It also requires separate development for different platforms (iOS, Android, etc.). Mobile website and mobile web app are less expensive options as they can be built using web technologies like HTML, CSS, and JavaScript. Hybrid HTTP combines the features of native and web apps, but it still requires significant development time and resources, making it a more expensive option than a mobile website or web app.

Question 14

What tools or technologies are available for providing interactivity and active content on a website and what functionality do they add? Describe at least five.

Accepted Answer

The answer of What tools or technologies are available for...

Question 15

All of the following are important factors in search engine optimization except:

Accepted Answer

Adhering to privacy policies is important for legal and ethical reasons, but it is not a direct factor in search engine optimization (SEO), which focuses on improving website visibility in search engine results.

Question 16

All of the following are website design features that annoy customers except:

Accepted Answer

Slow-loading pages, pop-under ads, and splash pages are all known to annoy customers and can lead to a negative user experience. However, multi-browser functionality is not an annoying feature and is actually important for ensuring that a website is accessible to all users, regardless of the browser they use.

Question 17

Which of the following statements about responsive web design (RWD)is not true?

Accepted Answer

RWD can work for any type of site, not just those with complex functionality.

Question 18

Which of the following is not part of the LAMP open source web development model?

Accepted Answer

The LAMP open source web development model consists of Linux, Apache, MySQL, and PHP. Microsoft IIS is not part of this model.

Question 19

PHP is an open source,general purpose scripting language that is most frequently used in server-side Web applications to generate dynamic web page content.

Accepted Answer

PHP is indeed an open source, general purpose scripting language that is widely used in server-side Web applications to generate dynamic web page content.

Question 20

____________ provides a set of standards for communicating between a browser and a program running on a server that allows for interaction between the user and server.

Accepted Answer

Common Gateway Interface (CGI) is a set of standards for communicating between a browser and a program running on a server that allows for interaction between the user and server. It is a way to create dynamic websites and web applications. ColdFusion, JavaScript, and VBScript are all programming languages or technologies that can be used in conjunction with CGI. However, none of them alone provide a set of standards for communication between a browser and server.
