CPACC Document and Media Accessibility Questions and Answers 2 — Questions and Answers
Question 1: What does 'tagged PDF' mean in the context of document accessibility?
- A PDF with a watermark applied for copyright purposes
- A PDF containing semantic structure tags that define reading order and element roles (Correct answer)
- A PDF with embedded metadata for file management systems
- A PDF that has been digitally signed
Correct answer: A PDF containing semantic structure tags that define reading order and element roles
Tagged PDFs include structural tags (headings, paragraphs, lists, tables) that allow assistive technologies to interpret and present content correctly.
Question 2: Which of the following is an accessibility requirement for data tables in documents?
- Tables must always be presented as images for visual consistency
- Header cells must be marked up to identify the headers for rows and columns (Correct answer)
- Tables should be replaced with plain text lists in all accessible documents
- Tables must contain no more than five columns to be accessible
Correct answer: Header cells must be marked up to identify the headers for rows and columns
Marking up header cells with appropriate tags (e.g., <th> in HTML or header cell designations in PDF) allows screen readers to announce which header applies to each data cell.
Question 3: What is a 'reading order' issue in an accessible PDF?
- The font size is too small to read without magnification
- The order in which a screen reader presents content does not match the logical visual flow (Correct answer)
- The document lacks a table of contents
- Hyperlinks in the document are not underlined
Correct answer: The order in which a screen reader presents content does not match the logical visual flow
Reading order problems occur when the underlying tag sequence in a PDF does not match the intended logical order, causing screen readers to announce content out of sequence.
Question 4: What multimedia accessibility feature benefits users who are blind and listening to an audio-only podcast?
- Closed captions
- Audio descriptions
- A transcript (Correct answer)
- Color-coded speaker labels
Correct answer: A transcript
A text transcript allows users who are deaf-blind (using braille displays) or who cannot access audio to read the full content of a podcast or audio recording.
Question 5: In accessible document authoring, what is the correct accessibility practice for a decorative image?
- Provide a detailed alt text describing the decoration
- Assign a null (empty) alt attribute so screen readers skip it (Correct answer)
- Replace all decorative images with text descriptions
- Use the image filename as the alt text
Correct answer: Assign a null (empty) alt attribute so screen readers skip it
Decorative images that convey no meaning should have an empty alt attribute (alt="") so screen readers ignore them and avoid presenting irrelevant information.
Question 6: Which WCAG success criterion most directly governs the requirement for captions on prerecorded video content?
- 1.1.1 Non-text Content
- 1.2.2 Captions (Prerecorded) (Correct answer)
- 1.4.3 Contrast (Minimum)
- 2.4.6 Headings and Labels
Correct answer: 1.2.2 Captions (Prerecorded)
WCAG 1.2.2 Captions (Prerecorded) at Level A requires synchronized captions for all prerecorded audio content in synchronized media.
