WCAG 1.2.4 (Level AA) requires captions for all live audio content in synchronized media, such as live-streamed classes.
Question 2: An instructor uses a flashing graphic in a course to draw attention. What risk does this create?
- It may trigger seizures in users with photosensitive epilepsy, violating WCAG 2.3.1 (Correct answer)
- It increases cognitive load for all learners equally
- It violates copyright law
- It slows page load time only
Correct answer: It may trigger seizures in users with photosensitive epilepsy, violating WCAG 2.3.1
WCAG 2.3.1 prohibits content that flashes more than three times per second, as it can trigger seizures in photosensitive users.
Question 3: What is a 'transcript' in the context of accessible multimedia, and when is it required?
- A text version of all audio and visual information; required for audio-only content at Level A (Correct answer)
- An auto-generated caption file embedded in the video player
- A summary of key points provided at the end of a lecture
- A bibliography of sources cited in the video
Correct answer: A text version of all audio and visual information; required for audio-only content at Level A
WCAG 1.2.1 requires a text transcript for audio-only pre-recorded content so deaf users can access the information.
Question 4: Which practice ensures that online discussion forums are accessible to users with disabilities?
- Using semantic HTML, providing alt text for images, and ensuring keyboard navigation (Correct answer)
- Limiting posts to 140 characters
- Using only images to represent posts
- Requiring users to log in via social media
Correct answer: Using semantic HTML, providing alt text for images, and ensuring keyboard navigation
Semantic HTML, image alt text, and keyboard navigation collectively ensure forum content is accessible to screen reader and keyboard-only users.
Question 5: When a student submits a form with an error, which WCAG criterion requires that the error be described to the user in text?
- 3.3.1 Error Identification (Correct answer)
- 2.4.6 Headings and Labels

Question 6: Which tool is commonly used to evaluate the accessibility of a web-based course for WCAG 2.1 compliance?
- WAVE (Web Accessibility Evaluation Tool) (Correct answer)
- Google PageSpeed Insights
- Grammarly
- Canva Accessibility Checker
Correct answer: WAVE (Web Accessibility Evaluation Tool)
WAVE is a widely used free web accessibility evaluation tool developed by WebAIM that identifies WCAG issues directly in the browser.
Question 7: A student with a motor disability uses switch access to navigate online courses. Which WCAG principle most directly supports this need?
- Operable — ensuring all functionality is available via keyboard or equivalent input (Correct answer)
- Perceivable — ensuring content is presented in multiple formats
- Understandable — ensuring content is readable
- Robust — ensuring compatibility with assistive technologies
Correct answer: Operable — ensuring all functionality is available via keyboard or equivalent input
Switch access relies on keyboard-equivalent navigation; WCAG's Operable principle (2.1.1) requires all functionality to work without a mouse.
