Question 2

Django follows the ________ programming principle.
A) CoC
B) WYSIWYG
C) DRY
D) LAMP

Accepted Answer

Django follows the DRY (Don't Repeat Yourself) programming principle, which states that every piece of knowledge or logic should have a single and unambiguous representation within a system. This helps to make the code more maintainable and less prone to errors or inconsistencies. CoC (Convention over Configuration) is a general programming principle that Django also adheres to, but it is not as specific to Django as DRY. WYSIWYG (What You See Is What You Get) and LAMP (Linux, Apache, MySQL, PHP) are not programming principles at all, but rather technologies or concepts related to web development.

Question 3

________ is a programming language invented by Netscape used to control the objects on an HTML page and handle interactions with the browser.
A) VBScript
B) ActiveX
C) ColdFusion
D) JavaScript

Accepted Answer

JavaScript is the programming language invented by Netscape used to control the objects on an HTML page and handle interactions with the browser. VBScript is a scripting language developed by Microsoft and is primarily used with Internet Explorer. ActiveX is a technology framework used by Microsoft for building interactive web content and applications. ColdFusion is a web development language that allows developers to create dynamic web pages and applications.

Question 4

Building which of the following is the least expensive path to creating a mobile presence?
A) native app
B) mobile website
C) mobile web app
D) hybrid HTTP

Accepted Answer

Building a mobile website is typically the least expensive option since it requires less specialized knowledge and can be accessed across multiple devices without the need for different versions or updates. Additionally, a mobile website can be created using existing tools and platforms like WordPress, which can reduce development costs. Native apps, mobile web apps, and hybrid HTTP all require more specialized knowledge and potentially higher development costs.

Question 5

All of the following are key design principles of responsive web design except:
A) flexible grid-based layouts.
B) media queries.
C) coding by convention.
D) flexible images and media.

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 all essential components of responsive web design.

Question 6

All of the following are website design features that annoy customers except:
A) slow-loading pages.
B) pop-under ads.
C) splash pages.
D) multi-browser functionality.

Accepted Answer

ColdFusion, JavaScript, and VBScript are all programming languages or tools that can be used in conjunction with CGI, but they are not themselves the standard for communication between the browser and server.

D) RWD can be costly.

Accepted Answer

Responsive web design can work for any type of website, regardless of its complexity. RWD tools such as HTML5 and CSS3 are necessary for designing responsive websites. RWD is designed to adjust automatically to any screen resolution, making it easy to view on any device. However, implementing RWD can be costly due to the need for specialized design and development expertise.

Question 10

Question 16

The primary way a website is able to personalize the content presented to a visitor is through the use of:
A) privacy policies.
B) cookies.
C) accessibility rules.
D) site management tools.

Accepted Answer

Cookies are small text files that are stored on a visitor's computer by a website. They contain information about the visitor's preferences and browsing history. This information can be used to personalize the content presented to the visitor on subsequent visits to the site. Privacy policies, accessibility rules, and site management tools are all important aspects of website design and maintenance, but they do not directly enable personalization of content.

Question 19

Ruby on Rails is based on which of the following philosophies?
A) SLDC
B) CoC
C) LAMP
D) Ajax

Accepted Answer

Ruby on Rails follows the Convention over Configuration philosophy, which means that it provides default conventions for development tasks, reducing the need for configuration and allowing developers to focus on writing code instead. SLDC (Software Development Life Cycle) is a methodology for software development, LAMP is a software bundle for web development, and Ajax is a technique for creating dynamic web pages.

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 optimized for the device?
A) LAMP
B) AWD
C) mobile first design

AWD (Adaptive Web Design) is a server-side technique that detects the attributes of the device making the request and loads a version of a site optimized for the device by using predefined templates. LAMP (Linux, Apache, MySQL, PHP) and RoR (Ruby on Rails) are web development frameworks while mobile first design is a design approach that emphasizes designing for mobile devices before designing for larger screens.
