, Question 1
A large e‑commerce website must function seamlessly across desktop,
tablet, and mobile devices while maintaining a consistent layout. Which
design approach best ensures this outcome?
A. Fixed layout
B. Fluid layout without media queries
C. Responsive grid system with fluid images and media queries
D. Adaptive design using static breakpoints only
ANS: C
Rationale: A responsive grid system that uses fluid images and media
queries adjusts content based on the viewport size. This approach
ensures consistency across devices without resorting to fixed dimensions.

Question 2
In a redesign of a mobile banking app, user research revealed that
visually impaired users struggled with reading on-screen information.
Which aspect of UI design is most critical to address in this case?
A. Using elaborate animations
B. Ensuring high contrast ratios and scalable typography
C. Reducing button sizes to fit more information
D. Limiting content to a single color palette
ANS: B
Rationale: High contrast ratios and scalable typography are
fundamental to accessible design. They enhance readability for users
with visual impairments and improve the overall accessibility of the
interface.
---
Question 3
When evaluating a desktop productivity tool, designers noted that subtle
animations and micro-interactions increased user engagement. What is

,the primary benefit of these micro-interactions?
A. They distract the user from errors.
B. They provide immediate and intuitive feedback during user
interactions.
C. They slow down the interface to prevent rapid inputs.
D. They allow users to personalize the UI extensively.
ANS: B
Rationale: Micro-interactions supply immediate visual or haptic
feedback that informs users about the result of their actions, enhancing
the overall interactivity and satisfaction.

Question 4
In a case study of a government portal redesign, which cognitive design
principle is most effective in reducing user error on complex forms?
A. Presenting all options in one view to squeeze more information
B. Applying Hick’s Law to limit the number of choices in each step
C. Using as many colors as possible to differentiate sections
D. Relying solely on tooltips for guidance
ANS: B
Rationale: Hick’s Law states that increasing the number of choices
increases decision time. Limiting choices reduces cognitive load and leads
to fewer errors, particularly on complex forms.
---
Question 5
A multinational enterprise is building a design system to be used across
its suite of applications. What is the primary benefit of a centralized
component library in this scenario?
A. It enforces design consistency and accelerates both development and
maintenance.
B. It mandates identical layouts for all applications regardless of context.
C. It requires each team to rebuild UI components independently.

, D. It eliminates the need for user testing entirely.
ANS: A
Rationale: A centralized component library standardizes reusable UI
components and style guides, ensuring consistency across products and
speeding up design and development efforts.
---
Question 6
In a case study on a healthcare provider’s web portal, simplifying
navigation was a key goal. Which UI design principle is most crucial to
achieve minimal user confusion?
A. Complex navigation menus
B. Clear and consistent labeling and organization of tasks
C. Extensive use of non-standard icons
D. Heavy reliance on animations for transitions
ANS: B
Rationale: Clear labeling and consistent design patterns help users
navigate interfaces intuitively. Reducing complexity minimizes confusion
and enhances usability.
---
Question 7
A SaaS company wants to optimize its user interface through iterative
design improvements. Which method is most effective for validating
design changes based on real user behavior?
A. Ignoring user feedback in favor of design trends
B. A/B testing different layouts
C. Sole reliance on in-house expert reviews
D. Prolonged development cycles with infrequent updates
ANS: B
Rationale: A/B testing enables designers to compare two or more
design variations and choose the one that best meets user needs based
on quantitative data.
