1. Which WCAG principle requires information and user-interface components
to be presented in ways users can perceive?
A. Operable
B. Understandable
C. Robust
D. Perceivable
Correct Answer: D. Perceivable
Rationale: The Perceivable principle focuses on ensuring that information and
interface components can be presented to users in forms they can perceive, such
as text alternatives, captions, adaptable content, and distinguishable visual
presentation.
2. What is the primary purpose of the alt attribute on an informative image?
A. To provide a text alternative that communicates the image's relevant
information
B. To increase the image's resolution
C. To control the image's visual dimensions
D. To prevent the image from loading
Correct Answer: A. To provide a text alternative that communicates the image's
relevant information
,Rationale: Alternative text provides a textual equivalent for meaningful images so
that users who cannot perceive the image can still access its relevant information.
3. Which HTML element is most appropriate for a primary page heading?
A. <span>
B. <h1>
C. <div>
D. <strong>
Correct Answer: B. <h1>
Rationale: The <h1> element identifies the page's primary heading semantically.
Assistive technologies can use semantic heading structures to help users
understand and navigate page content.
4. What is the main accessibility advantage of using native HTML controls
instead of recreating them with generic elements?
A. Native controls require more JavaScript
B. Native controls automatically remove all accessibility requirements
C. Native controls generally provide built-in semantics and expected interaction
behavior
D. Native controls prevent keyboard interaction
Correct Answer: C. Native controls generally provide built-in semantics and
expected interaction behavior
Rationale: Native HTML controls such as buttons, links, and form inputs have
established semantics and browser behavior that assistive technologies can
generally interpret. Recreating these behaviors with generic elements often
requires additional accessibility work.
5. Which WCAG principle is most directly concerned with making functionality
available through keyboard interaction?
,A. Perceivable
B. Operable
C. Understandable
D. Robust
Correct Answer: B. Operable
Rationale: The Operable principle includes requirements concerning keyboard
accessibility, sufficient time, seizure prevention, navigation, and other ways users
interact with functionality.
6. A custom button can only be activated with a mouse. What is the primary
accessibility problem?
A. It lacks sufficient color contrast
B. It may be unavailable to keyboard-only users
C. It contains too much text
D. It uses a responsive layout
Correct Answer: B. It may be unavailable to keyboard-only users
Rationale: Functionality must be operable through a keyboard interface. A control
that requires mouse interaction can prevent users who cannot use a mouse from
accessing that functionality.
7. Which HTML element should normally be used for an action that submits a
form?
A. <button>
B. <section>
C. <label>
D. <p>
Correct Answer: A. <button>
Rationale: A button is the semantic HTML element intended for user actions such
as submitting a form. Native buttons also provide expected keyboard and
accessibility behavior.
, 8. What is the primary purpose of a <label> associated with a form input?
A. To provide a visible or programmatically associated description of the input
B. To submit the form automatically
C. To hide the input from assistive technology
D. To change the input's data type
Correct Answer: A. To provide a visible or programmatically associated
description of the input
Rationale: Labels identify the purpose of form controls. Proper association allows
assistive technology users to understand what information a control requires.
9. Which attribute can provide an accessible name for an element when
appropriate?
A. aria-label
B. tab-size
C. border-style
D. line-height
Correct Answer: A. aria-label
Rationale: aria-label can provide an accessible name for certain elements when a
suitable visible label or native naming mechanism is not available. It should be
used appropriately rather than replacing semantic HTML unnecessarily.
10. What is the primary purpose of WAI-ARIA?
A. To replace HTML entirely
B. To add semantics and states or properties to user-interface components when
needed
C. To improve server performance
D. To compress web pages
