CPACC Accessibility Auditing and Testing 4 — Questions and Answers
Question 1: When conducting a screen reader test on a modal dialog, what behavior should you verify first?
- Focus moves to the dialog when it opens (Correct answer)
- The dialog has a visible border
- All images inside the dialog have alt text
- The dialog is positioned at the top of the page
Correct answer: Focus moves to the dialog when it opens
Focus must move into the modal when it opens so screen reader users are immediately aware of and can interact with the dialog content.
Question 2: Which WCAG success criterion requires that users can turn off, adjust, or extend time limits?
- 1.4.4 Resize Text
- 2.2.1 Timing Adjustable (Correct answer)
- 2.1.1 Keyboard
- 3.2.2 On Input
Correct answer: 2.2.1 Timing Adjustable
WCAG 2.2.1 Timing Adjustable requires that time limits set by content can be turned off, adjusted, or extended by the user.
Question 3: A tester finds that a form error message appears visually but is not announced by a screen reader. Which ARIA attribute would most directly fix this?
- aria-label
- aria-live='assertive' (Correct answer)
- aria-hidden='false'
- aria-describedby
Correct answer: aria-live='assertive'
Using aria-live='assertive' on the error container causes screen readers to immediately announce the error message when it appears.
Question 4: During an audit, you discover a carousel that auto-plays and has no pause button. Which WCAG criterion does this violate?
- 1.2.2 Captions (Prerecorded)
- 2.2.2 Pause, Stop, Hide (Correct answer)
- 2.3.1 Three Flashes or Below Threshold
- 1.4.5 Images of Text
Correct answer: 2.2.2 Pause, Stop, Hide
WCAG 2.2.2 Pause, Stop, Hide requires that moving, blinking, or auto-updating content can be paused, stopped, or hidden by the user.
Question 5: What is the primary purpose of using both automated and manual testing methods during an accessibility audit?
- Automated tools find all issues; manual testing confirms severity
- Automated tools catch about 30-40% of issues; manual testing finds the rest (Correct answer)
- Manual testing is only needed for WCAG AAA compliance
- Automated tools are sufficient for Level AA conformance claims
Correct answer: Automated tools catch about 30-40% of issues; manual testing finds the rest
Automated tools typically identify only 30-40% of accessibility issues, so manual testing is essential to uncover barriers that require human judgment.

- 4.1.2 Name, Role, Value
- 2.1.1 Keyboard (Correct answer)
- 1.3.1 Info and Relationships
- 2.4.3 Focus Order
Correct answer: 2.1.1 Keyboard
WCAG 2.1.1 Keyboard requires that all functionality is operable through a keyboard interface without requiring specific timings.
Question 7: When evaluating color contrast for large text, what is the minimum contrast ratio required at WCAG Level AA?
- 7:1
- 4.5:1
- 3:1 (Correct answer)
- 2:1
Correct answer: 3:1
WCAG 1.4.3 requires a contrast ratio of at least 3:1 for large text (18pt or 14pt bold) at Level AA.
