SECTION 1: HTML5 FUNDAMENTALS AND SEMANTIC
ELEMENTS
Question 1
What can you do to ensure that your Web page content is rendered
appropriately regardless of the browser used to render it
,A. Incorporate languages and technologies such as Java ActiveX
Microsoft Silverlight and Adobe Flash in your Web pages
B. Follow W3C standards carefully choose one standard version of any
given language you use and apply that standard consistently
C. Write code in multiple versions of any given language to maximize
the number of browsers in which your pages will render correctly
D. Avoid using HTML5 APIs in your Web pages
Correct Answer B
Rationale Following W3C standards carefully and applying one standard
version consistently ensures cross browser compatibility. Proprietary
technologies like Flash and Silverlight are deprecated and not
recommended. Writing multiple versions is inefficient and unnecessary.
Avoiding HTML5 APIs is counterproductive as they are widely
supported.
Question 2
Which HTML 4.01 flavor required the separation of presentation and
content
A. HTML 4.01 Standard
B. HTML 4.01 Strict
C. HTML 4.01 Frameset
,D. HTML 4.01 Transitional
Correct Answer B
Rationale HTML 4.01 Strict required the separation of presentation and
content. Transitional allowed some presentational elements and
attributes. Frameset allowed frames. The Strict doctype enforces
semantic markup.
Question 3
To what does the term app refer in modern web development
A. Relatively small programs that enable components of an application
to work together to produce a desired functionality
B. Relatively small applications developed exclusively for mobile
devices
C. Relatively simple Web pages that respond to user screen size
D. Standalone desktop applications
Correct Answer A
Rationale An app refers to small programs that enable application
components to work together. While apps are common on mobile
, devices they are not exclusively mobile. Responsive web pages are not
apps. Standalone desktop applications are not the same as web apps.
Question 4

A. HTML CSS and PHP
B. HTML CSS and JavaScript
C. HTML XML and JSON
D. CSS JavaScript and PHP
Correct Answer B
Rationale The web development trifecta consists of HTML for structure
CSS for presentation and JavaScript for behavior. Together these three
technologies form the foundation of front end web development.
