CPACC MCQ 2 — Questions and Answers
Question 1: Which of the following is NOT one of the seven principles of universal design?
- Equitable use
- Tolerance for error
- Maximum automation (Correct answer)
- Simple and intuitive use
Correct answer: Maximum automation
The seven principles are equitable use, flexibility in use, simple and intuitive use, perceptible information, tolerance for error, low physical effort, and size and space for approach and use. Maximum automation is not among them.
The seven principles of universal design were developed by Ronald Mace and colleagues at North Carolina State University in 1997. They guide designers to create products and environments that are inherently accessible to the widest range of users without requiring adaptation.
Question 2: What is the purpose of ARIA (Accessible Rich Internet Applications)?
- To replace HTML with a more accessible markup language
- To add semantic information to web elements so assistive technologies can interpret dynamic content (Correct answer)
- To automatically generate captions for video content
- To scan websites for accessibility violations
Correct answer: To add semantic information to web elements so assistive technologies can interpret dynamic content
WAI-ARIA provides attributes that supplement HTML to convey roles, states, and properties of interactive elements to assistive technologies.
WAI-ARIA defines a set of additional HTML attributes (roles, states, and properties) for assistive technologies. Key features include roles (role='dialog'), states (aria-expanded='true'), properties (aria-label), and live regions (aria-live) for dynamic content updates.
Question 3: Under the European Accessibility Act (EAA), which types of products and services must be accessible by June 2025?
- Only government websites
- Consumer products and services including e-commerce, banking, and transport (Correct answer)
- Only physical buildings and infrastructure
- Only mobile applications
Correct answer: Consumer products and services including e-commerce, banking, and transport
The EAA requires accessibility for a broad range of consumer products and services including computers, smartphones, e-commerce, banking, transport, and e-books.
The European Accessibility Act (Directive 2019/882) covers computers and operating systems, ATMs, smartphones, TV equipment, e-readers, e-commerce, banking, electronic communications, audiovisual media, transport services, and e-books. Unlike previous EU directives, the EAA extends requirements to the private sector.
Question 4: What is a 'screen magnifier' used for?
- Increasing the physical size of a computer monitor
- Enlarging a portion of the screen display for users with low vision (Correct answer)
- Improving the resolution of images on a webpage
- Converting text to audio for blind users
Correct answer: Enlarging a portion of the screen display for users with low vision
Screen magnifiers enlarge content on screen to make it readable for people with low vision who have some remaining sight.
Screen magnifiers like ZoomText, MAGic, and built-in OS magnifiers enlarge a portion or all of the screen display. They differ from screen readers in that they assist users who have residual vision rather than users who are completely blind.
Question 5: Which type of disability would benefit most from providing captions on video content?
- Motor disabilities
- Visual impairments
- Hearing impairments (Correct answer)
- Cognitive disabilities exclusively
Correct answer: Hearing impairments
Captions primarily benefit people who are deaf or hard of hearing by providing a text representation of spoken dialogue and significant audio information.
Video captions serve people who are deaf or hard of hearing. WCAG addresses captions under SC 1.2.2 (Captions - Prerecorded, Level A) and SC 1.2.4 (Captions - Live, Level AA). Captions also benefit people in noisy environments, non-native speakers, and those with cognitive disabilities.
Question 6: What does the term 'keyboard trap' refer to in web accessibility?
- A feature that locks the keyboard to prevent accidental input
- A situation where keyboard focus gets stuck in a component and the user cannot navigate away (Correct answer)
- A security measure that disables keyboard shortcuts
- A design pattern for creating accessible keyboard shortcuts
Correct answer: A situation where keyboard focus gets stuck in a component and the user cannot navigate away
A keyboard trap occurs when a user navigating with a keyboard becomes stuck in a particular interface component with no way to move focus away.
A keyboard trap violates WCAG Success Criterion 2.1.2 (No Keyboard Trap, Level A). Common causes include improperly coded modal dialogs, embedded media players, and third-party widgets. For modals, Escape should close the dialog and return focus.
