TRUE, unless an alternate version without the failure is also provided.
Can content meet WGAC Success Criterion without using any of the sufficient techniques?
Yes
Does content that passes the sufficient techniques always meet all WCAG success criteria?
No, some are non-technology specific and may need more work to be conform for all types of technologies.

Normative are rules that must be followed, non-normative are merely suggestions.
What is the purpose of WAI-ARIA
To make dynamic web content accessible
How does ARIA make web sites more accessible? (4 things)
Defines best practices for: widget structure, keyboard behaviors, dynamic content, promotes interoperability
What is ATAG?
Authoring Tool Accessibility Guidelines
It’s a W3C Spec of recommendations on how third party tools like editors, CMS, social media, widgets should be made accessible
What is the power of automated ATAG? (4)
What is its limitation? (1)
Powers: Allows devs to use tool of their choosing Supports diverse workflows Supports result aggregation Supports accessible resource discovery
Limitation:
the current state of technology does not allow every web site content accessibliity problem to be identified automatically
How many success criteria are in WCAG 2.1?
63
How many new success criterion are added with WCAG 2.2? Can you name them?
NINE and eight of them are Level A or AA. Accessible Authentication Dragging Movements Consistent Help Page Break Navigation Focus Appearance (Min and Enhanced) Visible Controls Target Size Redundant Entry
Name some of the Techniques WCAG provides to help developers meet the criteria?
ARIA Techniques Client-Side Script Techniques CSS Techniques Common Failures General Techniques HTML Techniques PDF Techniques Server-Side Script Techniques Silverlight Techniques SMIL Techniques Plain Text Techniques
