DETAILED ANSWERS (VERIFIED
ANSWERS) ALREADY GRADED A+
1. According to WCAG 2.1 Success Criterion 1.4.10, what is required
for content that requires horizontal scrolling at 320 CSS pixels?
A. It must be zoomable to 200% without scrolling
B. It must support both portrait and landscape orientations
C. It must not require scrolling in two directions
D. It must provide an alternative linearized version
Rationale: The correct answer is C. It must not require scrolling in two
directions. WCAG 2.1 SC 1.4.10 (Reflow) states that content should not
require scrolling in both horizontal and vertical directions at 400%
zoom. This tests knowledge of specific WCAG criteria and their
technical requirements.
2. When implementing ARIA landmarks, which role should be used for
the primary content of a page?
A. role="navigation"
B. role="main"
C. role="contentinfo"
D. role="complementary"
,Rationale: The correct answer is B. role="main". The main landmark
identifies the primary content of the document. Navigation (A) is for
navigation menus, contentinfo (C) is typically for footer content, and
complementary (D) is for supporting content. This tests practical
implementation of WAI-ARIA.
3. Which assistive technology is primarily designed for users with
mobility impairments?
A. Screen reader
B. Screen magnifier
C. Switch device
D. Braille display
Rationale: The correct answer is C. Switch device. Switch devices allow
users with limited mobility to control computers through simple
switches, while screen readers (A) are for visual impairments, screen
magnifiers (B) for low vision, and Braille displays (D) for blind users.
This tests knowledge of assistive technology mapping to disabilities.
4. Under the ADA, what is the timeframe for providing effective
communication accommodation?
A. Within 24 hours of request
B. As soon as possible based on circumstances
C. Within the next business day
D. Within 72 hours of request
Rationale: The correct answer is B. As soon as possible based on
circumstances. The ADA requires timely accommodation based on
factors like the nature, length, and complexity of the communication and
the entity's capabilities. This tests legal compliance knowledge beyond
just technical standards.
5. For a video with audio content, WCAG 2.1 Success Criterion 1.2.5
requires:
A. Captions
B. Audio description
,C. Sign language interpretation
D. Extended audio description
Rationale: The correct answer is B. Audio description. Success Criterion
1.2.5 (Level AA) specifically requires audio description for pre-recorded
video content when the visual information is not fully described in the
main audio track. Captions (A) are for dialogue and sound effects (SC
1.2.2). Sign language (C) is a Level AAA requirement (SC 1.2.6).
Extended audio description (D) is for Level AAA when pauses are
insufficient.
6. Which of the following best describes "operable" under WCAG's
POUR principles?
A. Content is readable and understandable
B. Interface components and navigation are usable
C. Information and user interface are perceivable
D. Content is robust enough for current and future technologies
Rationale: The correct answer is B. Operable means users can
successfully interact with all controls and navigation using various
methods (keyboard, voice, etc.). Perceivable (C) is about presentation of
information. Understandable (A) relates to comprehension of content
and interface. Robust (D) refers to compatibility with user agents and
assistive tech.
7. Under Section 508, which standard applies to non-web software?
A. WCAG 2.0 Level AA
B. Section 255 guidelines
C. EN 301 549
D. Revised 508 Standards Chapter 5
Rationale: Correct answer is D. Chapter 5 of the Revised 508 Standards
applies to non-web software. WCAG 2.0 Level AA (A) applies to web
content under Section 508. Section 255 (B) applies to
telecommunications. EN 301 549 (C) is a European standard.
, 8. Which HTML5 element is most appropriate for marking up a site's
main navigation menu?
A. <div role="navigation">
B. <menu>
C. <nav>
D. <section aria-label="Navigation">
Rationale: Correct answer is C. The <nav> element is the semantic
HTML5 element explicitly intended for navigation links. While ARIA
roles or <section> with a label can be used, using native HTML
semantics is the first rule of ARIA and ensures the best compatibility.
9. When testing keyboard accessibility, which visual indicator should
appear for focused elements?
A. A visible focus indicator with a 3:1 contrast ratio against adjacent
colors
B. A dotted outline that matches the brand's color palette
C. Any visible change, as long as it's discernible
D. No visual indicator is needed if hover styles are present
Rationale: Correct answer is A. WCAG 2.1 Success Criterion 2.4.11
(Focus Appearance) requires the focus indicator area to have a contrast
ratio of at least 3:1 against adjacent colors, among other requirements.
It's not enough to simply have "any visible change" (C), and hover styles
(D) do not replace focus indicators.
10. A complex data table uses rowspan and colspan attributes. To ensure
accessibility, what should be implemented?
A. Use scope="row" and scope="col" only
B. Provide a linearized text alternative for the entire table
C. Use ARIA role="grid" with aria-rowindex and aria-colindex
D. Associate header cells with data cells using headers and id attributes
