ISTQB CT-UT Dumps Questions Answers

The Web Content Accessibility Guidelines (WCAG) provide standards to ensure websites are accessible to people with disabilities. They specifically address:

i. Text resizability (SC 1.4.4),

iii. Text alternatives for non-text content (SC 1.1.1),

iv. Keyboard accessibility (SC 2.1.1),

v. Device independence, which includes not relying solely on mouse input.

Visually appealing design (ii) is not an accessibility requirement and is thus not a WCAG focus. The correct answer is D: i, iii, iv & v are true; ii is false.

Usability is defined in ISO 9241-11 as the extent to which a system can be used by specified users to achieve specified goals with effectiveness, efficiency, and satisfaction in a specified context of use. Without knowing the context—such as product complexity, user familiarity, device type, or purchasing habits—it is impossible to judge whether five minutes is good or bad. For complex items, five minutes may be reasonable, while for one-click purchases, it may be excessive. Thus, usability cannot be assessed solely based on one metric like time—it must be evaluated within its full usage context.

When actual users cannot be included, a usability review (often an expert or heuristic evaluation) is the most practical method. Trained evaluators examine the interface against usability principles and standards to identify potential issues. Surveys require user input, and usability testing cannot proceed without users. Accessibility evaluation targets inclusivity for users with impairments, which is related but not a substitute for overall usability evaluation. Therefore, option A is the only valid method under these constraints.
