CEAC Technology & Digital Tools 2 — Questions and Answers
Question 1: Which file format is most commonly used to ensure accessibility features are preserved when sharing CAD drawings of accessible routes?
- DWF (Design Web Format)
- PDF/UA (ISO 14289) (Correct answer)
- JPEG
- CSV
Correct answer: PDF/UA (ISO 14289)
PDF/UA (Universal Accessibility) is the ISO standard that preserves tagged structure and accessibility metadata when sharing design documents.
Question 2: A consultant uses BIM (Building Information Modeling) to audit an existing facility. Which BIM capability is MOST useful for identifying ADA clearance conflicts?
- Rendering photorealistic images
- Clash detection and spatial analysis (Correct answer)
- Scheduling construction timelines
- Generating cost estimates
Correct answer: Clash detection and spatial analysis
Clash detection in BIM identifies spatial conflicts such as insufficient clearance dimensions required by ADA standards.
Question 3: What is the primary purpose of a Geographic Information System (GIS) in environmental accessibility consulting?
- Generating 3D renderings of interiors
- Mapping spatial relationships of accessible routes across a site or region (Correct answer)
- Writing accessibility compliance reports
- Measuring decibel levels for hearing accessibility
Correct answer: Mapping spatial relationships of accessible routes across a site or region
GIS maps and analyzes spatial data, making it ideal for assessing accessible route connectivity across large sites or jurisdictions.
Question 4: When using laser scanning (LiDAR) for accessibility audits, what is the primary deliverable that consultants extract?
- A colored photograph of the building facade
- A point cloud converted to precise as-built dimensions (Correct answer)
- An energy performance certificate
- A structural load calculation
Correct answer: A point cloud converted to precise as-built dimensions
LiDAR scanning produces point clouds that are processed into accurate as-built measurements critical for verifying ADA compliance dimensions.
Question 5: Which mobile application feature is MOST critical for a field accessibility auditor collecting ADA compliance data on-site?
- Augmented reality gaming overlay
- GPS-tagged photo capture with custom checklist forms (Correct answer)
- Social media sharing integration
- Offline video streaming
Correct answer: GPS-tagged photo capture with custom checklist forms
GPS-tagged photos linked to checklist items allow auditors to document exact locations of deficiencies for accurate reporting.
Question 6: A CEAC consultant needs to verify that a website meets WCAG 2.1 Level AA. Which automated tool provides a first-pass scan for common accessibility errors?
- Google Analytics
- WAVE (Web Accessibility Evaluation Tool) (Correct answer)
- Adobe Acrobat Reader
- AutoCAD
Correct answer: WAVE (Web Accessibility Evaluation Tool)
WAVE is a widely used browser-based tool that identifies WCAG errors such as missing alt text, poor color contrast, and improper heading structure.
Question 7: In digital accessibility auditing, what does the term 'keyboard trap' refer to?
- A physical keyboard that is incompatible with assistive technology
- A focus state where a keyboard user cannot navigate away from an element using standard keys (Correct answer)
- An inaccessible keyboard shortcut in a desktop application
- A security feature that locks keyboard input on shared devices
Correct answer: A focus state where a keyboard user cannot navigate away from an element using standard keys
A keyboard trap occurs when focus becomes stuck inside a component (e.g., a modal) and the user cannot escape using Tab, Shift+Tab, or arrow keys.
