ITPEC IP October 2021 Question 47
ITPEC IP October 2021 — Question 47 of 100
Ease of learning, pushbutton layout, and text size and color are all screen-usability considerations, so B, C, and D are correct. They directly affect how easily users understand, navigate, read, and operate the interface.
Answer (d)
Why not others:
- A, recovery time after a failure, is a system maintainability or availability measure rather than a property of easy-to-use screen design
- every alternative containing A substitutes an operational reliability concern for one of the genuine interface considerations
Key rule: Usable screen design focuses on learnability, clear control placement, legibility, consistency, and feedback to the user.
