CPACC Document and Media Accessibility Questions and Answers 4 — Questions and Answers
Question 1: When creating an accessible PDF form, which technique ensures screen readers announce form fields correctly?
- Using tooltip text only
- Adding tooltips and placeholder text
- Associating labels with form fields using proper tagging (Correct answer)
- Placing label text visually near the field
Correct answer: Associating labels with form fields using proper tagging
PDF form fields must have programmatically associated labels via proper tagging so assistive technologies can announce the field's purpose.
Question 2: Which WCAG success criterion specifically addresses the minimum contrast ratio for normal text at Level AA?
- 1.4.1 Use of Color
- 1.4.3 Contrast (Minimum) — 4.5:1 (Correct answer)
- 1.4.6 Contrast (Enhanced) — 7:1
- 1.4.11 Non-text Contrast — 3:1
Correct answer: 1.4.3 Contrast (Minimum) — 4.5:1
WCAG 1.4.3 requires a contrast ratio of at least 4.5:1 for normal text to meet Level AA.
Question 3: A caption file for a video uses the identifier 'WEBVTT' at the top of the file. What format is this?
- SubRip Text (SRT)
- Web Video Text Tracks (WebVTT) (Correct answer)
- TTML (Timed Text Markup Language)
- SMIL (Synchronized Multimedia Integration Language)
Correct answer: Web Video Text Tracks (WebVTT)
WebVTT files always begin with the 'WEBVTT' header and are the standard caption format for HTML5 video.
Question 4: An infographic in a Word document conveys complex data through color coding alone. Which remediation best addresses accessibility?
- Add a border around colored sections
- Increase the image resolution
- Provide a text-based summary or data table describing the information (Correct answer)
- Change the infographic colors to higher contrast shades
Correct answer: Provide a text-based summary or data table describing the information
A text-based summary or data table ensures users who cannot perceive color differences can still access the conveyed information.
Question 5: Which attribute in an HTML audio element provides a text transcript link for deaf users?
- aria-label
- longdesc
- No native attribute exists; a transcript link must be placed adjacent to the element (Correct answer)
- caption
Correct answer: No native attribute exists; a transcript link must be placed adjacent to the element
HTML has no built-in attribute for audio transcripts; the accessible solution is to provide a visible transcript link adjacent to the audio element.
Question 6: In the context of document accessibility, what does 'linearization' mean?
- Converting a document to a single-column layout
- The logical reading order that remains when visual formatting is removed (Correct answer)
- Compressing a PDF to reduce file size
- Converting hyperlinks to plain text
Correct answer: The logical reading order that remains when visual formatting is removed
Linearization refers to the logical order in which content is read when visual layout is stripped away, which is how screen readers process documents.
Question 7: When should extended audio description be used in a video?
- When background music is present
- When pauses in dialogue are too short to insert standard audio description (Correct answer)
- When the video has no captions
- When the video exceeds 30 minutes in length
Correct answer: When pauses in dialogue are too short to insert standard audio description
Extended audio description pauses the video playback to allow enough time to describe complex visual content when natural pauses are insufficient.
