ITPEC IP April 2026 Question 46
ITPEC IP April 2026 — Question 46 of 100
B, C, and D — learnability, control layout, and readable text directly affect screen usability.
Users benefit when operations are easy to learn, related buttons are arranged consistently, and text size and color remain legible with sufficient contrast. A, time to repair a failure, measures maintainability or recoverability of the system rather than ease of using a screen.
Answer (d)
Why not others: Options (a), (b), and (c) all include A and each omits one genuine usability item.
Key rule: UI usability concerns how readily users understand, perceive, and operate the interface; repair time concerns system operation and maintenance.
