CEAC Technology & Digital Tools 3 — Questions and Answers
Question 1: Which assistive technology standard must PDF documents comply with to be considered accessible under Section 508 guidelines?
- PDF 1.4
- PDF/A
- PDF/UA (ISO 14289-1) (Correct answer)
- PDF/X
Correct answer: PDF/UA (ISO 14289-1)
PDF/UA (Universal Accessibility) defines requirements for tagged structure, reading order, and alternative text that make PDFs accessible under Section 508.
Question 2: A consultant is reviewing a public transit app for accessibility. Which WCAG 2.1 success criterion addresses sufficient color contrast for text?
- 1.4.1 Use of Color
- 1.4.3 Contrast (Minimum) (Correct answer)
- 2.4.7 Focus Visible
- 3.3.1 Error Identification
Correct answer: 1.4.3 Contrast (Minimum)
WCAG 1.4.3 requires a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text to ensure readability for low-vision users.
Question 3: What does 'ARIA' stand for in web accessibility, and what is its primary function?
- Accessible Rich Internet Applications — adds semantic roles/states to HTML for assistive technologies (Correct answer)
- Automated Readability Index Algorithm — measures text complexity
- Accessible Route Integration Architecture — maps physical accessible paths
- American Rehabilitation Information Association — regulatory body
Correct answer: Accessible Rich Internet Applications — adds semantic roles/states to HTML for assistive technologies
WAI-ARIA provides attributes that expose dynamic web content and custom UI widgets to assistive technologies like screen readers.
Question 4: During a transition space audit, a consultant uses a digital measuring wheel with Bluetooth output. What is the key advantage of Bluetooth data transfer in this context?
- It eliminates the need for ADA compliance standards
- Measurements sync directly to a mobile form, reducing manual transcription errors (Correct answer)
- It allows measurements to be taken from 100 feet away
- It replaces the need for photographic documentation
Correct answer: Measurements sync directly to a mobile form, reducing manual transcription errors
Bluetooth-linked measuring tools sync data directly to field audit apps, reducing human error from manual re-entry of dimension values.
Question 5: Which software standard governs the data exchange format used when sharing building accessibility information between different BIM platforms?
- DXF (Drawing Exchange Format)
- IFC (Industry Foundation Classes) (Correct answer)
- STL (Stereolithography)
- OBJ (Wavefront Object)
Correct answer: IFC (Industry Foundation Classes)
IFC is the open ISO standard (ISO 16739) for exchanging BIM data between different software platforms while preserving building element properties.
Question 6: A CEAC consultant is evaluating a kiosk for ADA compliance. Which reach range requirement is most critical to verify using a digital measuring tool?
- The kiosk screen resolution must exceed 1080p
- Forward or side reach must be between 15 and 48 inches above the floor (Correct answer)
- The kiosk must have a minimum 24-inch wide base
- Response time must be under 2 seconds
Correct answer: Forward or side reach must be between 15 and 48 inches above the floor
ADA Standards require operable parts on kiosks to be within 15–48 inches (forward reach) or 9–54 inches (side reach) above the finished floor.
Question 7: When generating an accessibility compliance report using software tools, what data validation step is MOST important before submitting findings?
- Ensuring the report is formatted in a proprietary file type
- Cross-referencing automated findings with manual field verification (Correct answer)
- Removing all photographic evidence to reduce file size
- Sorting findings alphabetically by location name
Correct answer: Cross-referencing automated findings with manual field verification
Automated tools produce false positives and miss context-dependent issues, so manual field verification is essential to validate digital audit findings.
