1. Question 1 of 30

   When analyzing a major technology trend for product impact, which approach best demonstrates strategic discernment?

   • aStart with the specific user problem and product gaps, run a time-boxed spike with clear success criteria, and set data-driven go/no-go gates
   • bUse the Gartner hype cycle to determine the trend's maturity stage and align the investment timeline with its predicted trajectory
   • cBuild a prototype immediately to validate the trend's potential before competitors adopt it, or dismiss it entirely if the team lacks immediate expertise
   • dLaunch a comprehensive three-month research phase to explore all possible applications before committing to any implementation path
   Show the answer

   Answer: a · Start with the specific user problem and product gaps, run a time-boxed spike with clear success criteria, and set data-driven go/no-go gates

   A strong analysis anchors on user and business gaps first, then validates through bounded experiments with explicit, measurable decision gates rather than sentiment. Option C exemplifies the binary build-or-dismiss reaction the card identifies as the biggest red flag, whereas strategic discernment requires structured investigation before commitment.

2. Question 2 of 30

   Which scenario best justifies choosing a moderated usability test over a survey?

   • aObserving behavioral blockers in an interactive prototype before code solidifies
   • bValidating that a majority of users say they value one-click purchasing
   • cCollecting quantitative satisfaction ratings from thousands of users to prioritize a roadmap
   • dGauging user interest in a feature concept using a static mockup
   Show the answer

   Answer: a · Observing behavioral blockers in an interactive prototype before code solidifies

   Moderated tests reveal what users actually do, such as confusion or errors in interactive workflows, while surveys only capture self-reported opinions. Option B reflects the card's survey example of validating desire, which cannot uncover hidden interaction flaws.

3. Question 3 of 30

   When creating a shape in Figma, which keyboard modifier ensures it maintains perfect proportions, like a square or a circle?

   • aShift
   • bOption (Alt on Windows)
   • cCommand (Ctrl on Windows)
   • dSpacebar
   Show the answer

   Answer: a · Shift

   The card explicitly states to "hold Shift while dragging to constrain proportions (making a perfect square or circle)." Option/Alt is used for drawing or resizing from the center point, not for constraining proportions.

4. Question 4 of 30

   You need a single button instance to switch between default, hover, and disabled states automatically. What should you do?

   • aBuild a component set with a State property and wire Change to interactions between variants
   • bCreate three separate components and manually swap the instance on the canvas
   • cUse auto-layout on one frame to cycle through the different state layers
   • dDuplicate the button frame on the canvas and link them with overlay interactions
   Show the answer

   Answer: a · Build a component set with a State property and wire Change to interactions between variants

   Component sets group related states under one property, and Change to interactions let an instance switch variants automatically without manual swaps. Option B is wrong because separate components create duplication and require designers to swap instances by hand, which is exactly the red flag the card warns against.

5. Question 5 of 30

   Which workflow correctly makes a button inside Frame A navigate to Frame B when clicked in a Figma prototype?

   • aInstall a prototyping plugin, convert the button to an interactive component, and define the frame route in the plugin panel
   • bSelect Frame A and Frame B, then right-click and choose Add hyperlink to connect the two frames
   • cSwitch to Prototype mode, select the button layer, drag its interaction node to Frame B, and set the trigger to On Click with action Navigate To
   • dAdd auto layout to the button, enable vertical scrolling on Frame B, and press Present to test the transition
   Show the answer

   Answer: c · Switch to Prototype mode, select the button layer, drag its interaction node to Frame B, and set the trigger to On Click with action Navigate To

   The correct approach is to enter Prototype mode, use the interaction node on the specific button layer, and configure an On Click Navigate To interaction targeting Frame B. Option B is tempting because hyperlinks are common in other tools, but Figma does not use right-click hyperlinks for frame navigation.

6. Question 6 of 30

   When setting up a Smart Animate transition, which practice ensures a button smoothly tweens its width and corner radius between two frames?

   • aKeeping the button in the same group hierarchy with identical paths
   • bApplying matching auto layout settings and pixel-perfect alignment
   • cConverting the button to a raster image in both frames
   • dNaming the button layer identically in both frames and using compatible types
   Show the answer

   Answer: d · Naming the button layer identically in both frames and using compatible types

   Smart Animate matches layers by exact name across frames and interpolates properties like width and corner radius only between compatible types. Identical hierarchy and auto layout are not required, and raster images cannot morph vector properties.

7. Question 7 of 30

   When building a reusable interactive checkbox in Figma, which approach correctly handles state transitions between checked and unchecked variants?

   • aCreate a component set but manage all prototype connections at the page level for each instance
   • bCreate separate components for each state and use Navigate to when transitioning between them
   • cDuplicate the frame for every state combination and draw individual prototype connections between them
   • dBuild a component set with variants and wire Change to actions using On click and While hovering triggers
   Show the answer

   Answer: d · Build a component set with variants and wire Change to actions using On click and While hovering triggers

   A component set with Change to actions embeds interactions directly in the component so every instance automatically carries them. Duplicating frames creates unmaintainable noodle soup, Navigate to forces full frame transitions rather than local variant swaps, and page-level management defeats the purpose of reusable interactive components.

8. Question 8 of 30

   For which scenario is First Click Testing LEAST suitable?

   • aValidating the intuitive placement of a "Sign Up" button on a landing page.
   • bComparing two proposed designs for a website's primary navigation.
   • cTesting if users can locate the return policy link on an e-commerce product page.
   • dEvaluating the overall flow and potential drop-off points in a 5-step registration form.
   Show the answer

   Answer: d · Evaluating the overall flow and potential drop-off points in a 5-step registration form.

   First Click Testing is specifically designed to evaluate only the very first step of a user's journey, making it unsuitable for assessing multi-step processes or entire user flows. It excels at validating initial navigation and single-click clarity, as described in the other options.

9. Question 9 of 30

   In Figma, how do you configure a parent frame so its tall content scrolls while the header and footer stay fixed in place?

   • aCreate multiple frames showing different scroll positions and link them with drag interactions
   • bGroup the header, content, and footer into one layer, enable Clip content, and set the group to vertical overflow
   • cEnable vertical overflow on the parent frame, set the header to Stick to top, and leave the footer as Scroll with parent
   • dEnable Clip content and vertical overflow on the parent frame, set the header and footer to Fix position when scrolling, and leave the content as Scroll with parent
   Show the answer

   Answer: d · Enable Clip content and vertical overflow on the parent frame, set the header and footer to Fix position when scrolling, and leave the content as Scroll with parent

   Option D is correct because Clip content masks the overflow, vertical overflow enables native scrolling, and Fix position when scrolling pins the chrome while the content layer remains Scroll with parent. Option C is tempting because Stick to top sounds like it fixes the header, but it actually makes the element scroll until it hits the top and then freeze, which is wrong for a persistent header.

10. Question 10 of 30

    For which scenario would a visiontype be most effective?

    • aTo align a large organization on a 3-5 year strategic product vision and inspire bold innovation.
    • bTo facilitate rapid iteration and gather user feedback for short-term sprint planning.
    • cTo provide a static presentation of abstract goals to leadership for budget approval.
    • dTo meticulously document all features and technical specifications for an upcoming product launch.
    Show the answer

    Answer: a · To align a large organization on a 3-5 year strategic product vision and inspire bold innovation.

    A visiontype is designed to align large organizations on a long-term (3-5 year) strategic direction, encouraging bolder moves beyond incremental updates. It is explicitly stated that a visiontype is not for short-term sprint planning or documenting every possible feature, nor is it a static, abstract presentation.

11. Question 11 of 30

    What is the essential condition for a Figma frame to enable scrolling in a prototype?

    • aThe 'Overflow' setting must be 'Scroll with parent'.
    • bThe frame's 'Clip content' must be disabled.
    • cThe content must be larger than the frame's visible area.
    • dAll content inside must be in an Auto Layout frame.
    Show the answer

    Answer: c · The content must be larger than the frame's visible area.

    The card explicitly states that for a frame to scroll, "the content must be larger than the window" or "if content doesn't extend beyond the frame, there's nothing." Option A describes a setting for objects *within* a scrolling frame, not the fundamental condition for the frame itself to scroll.

12. Question 12 of 30

    Which of the following best describes the core benefit of using Figma's Interactive Components?

    • aThey simplify the process of connecting distinct screens by embedding navigation logic directly into frames.
    • bThey allow designers to create custom animations for any element on a page, regardless of its component status.
    • cThey enable interactions to be defined across variants from different component sets, enhancing modularity.
    • dThey drastically reduce the number of frames and prototype connections needed to manage multiple states within a single component.
    Show the answer

    Answer: d · They drastically reduce the number of frames and prototype connections needed to manage multiple states within a single component.

    Interactive Components embed prototype logic directly into component variants, eliminating the need for numerous duplicated frames and connections for state changes within a component. Option C is incorrect because the card explicitly states that interactions cannot be created between variants from different component sets.

13. Question 13 of 30

    When prototyping a scrollable list, if "Preserve scroll position" is active but the list resets after navigating away and back, what is the most likely reason?

    • aThe prototype connection used an "Instant" transition instead of "Smart Animate."
    • bThe scrollable layer on the initial list frame and the one on the returned-to list frame do not have identical names or structure.
    • cThe scrollable list was not explicitly marked as a "Scrolling content" frame in prototype settings.
    • dThe interaction to return to the list had "Reset scroll position" enabled.
    Show the answer

    Answer: b · The scrollable layer on the initial list frame and the one on the returned-to list frame do not have identical names or structure.

    The card explains that for scroll positions to be shared across different frames, the scrollable layers must have identical names and structure. If these do not match, Figma cannot apply the saved position, causing it to reset. While option D would also cause a reset, the question implies an unintended behavior when preservation is expected.

14. Question 14 of 30

    Which prototyping scenario most effectively leverages Figma expressions over simpler interaction methods?

    • aChanging a button's color when a user hovers over it.
    • bCalculating and displaying a running total for items added to a shopping cart.
    • cSwitching between different artboards in a linear user flow.
    • dToggling a checkbox's visual state between checked and unchecked.
    Show the answer

    Answer: b · Calculating and displaying a running total for items added to a shopping cart.

    Expressions are specifically for dynamic calculations and evaluations, such as updating a shopping cart total based on user input. Simple state changes like toggling a checkbox are better managed with component variants, not expressions.

15. Question 15 of 30

    You need to build a counter in Figma that increases by one when a user clicks a '+' button. Which approach correctly uses variables to update the display within a single frame?

    • aCreate component variants for each number and use the Change to action on the plus button to swap between them
    • bDuplicate frames showing different hardcoded numbers and link the plus button to the next frame on each click
    • cAssign a string variable to the text layer and update it on click by appending the digit 1 to the current value
    • dApply a number variable to the text layer, then add an On click Set variable action to the plus button using an expression to add one
    Show the answer

    Answer: d · Apply a number variable to the text layer, then add an On click Set variable action to the plus button using an expression to add one

    The correct workflow binds a number variable to the text layer and mutates it with a Set variable expression on click, keeping everything inside one frame. Option B is wrong because duplicating hardcoded frames avoids variables entirely and is a common red flag that shows a lack of understanding of dynamic state in Figma prototypes.

16. Question 16 of 30

    What is the fundamental way Figma treats video content within a design?

    • aAs an embedded object that requires a separate plugin for playback.
    • bAs a linked external resource that streams into the prototype.
    • cAs a fill property that can be applied to any shape.
    • dAs a specialized layer type dedicated to video playback.
    Show the answer

    Answer: c · As a fill property that can be applied to any shape.

    The card explicitly states that video in Figma is a "fill property, just like a solid color, gradient, or image," not a distinct video layer. Option D is a tempting distractor because many other design or video tools use dedicated video layers, but Figma's approach is unique.

17. Question 17 of 30

    Which approach correctly uses Figma variables to enable Submit only after a terms checkbox is checked?

    • aDuplicate the screen into checked and unchecked frames, wire the checkbox to swap between them, and enable Submit only on the checked frame.
    • bCreate a boolean variable toggled by the checkbox, add a conditional action to the Submit button that checks the variable before navigating, and bind the button's opacity to the same boolean.
    • cToggle a boolean variable on checkbox click and bind the Submit button's opacity to it, then use a regular On click interaction on Submit to navigate without adding a conditional check.
    • dRely on component variants alone by swapping the checkbox between checked and unchecked variants on click to control the Submit button's enabled state.
    Show the answer

    Answer: b · Create a boolean variable toggled by the checkbox, add a conditional action to the Submit button that checks the variable before navigating, and bind the button's opacity to the same boolean.

    The correct workflow requires a boolean variable, a conditional action on Submit that verifies the variable is true before navigating, and visual binding for feedback. Option C is tempting because it uses a variable and visual binding, but without the conditional check the Submit button would still fire when clicked even while appearing disabled.

18. Question 18 of 30

    If a Figma object has two distinct "On click" interactions stacked, what occurs when the object is clicked?

    • aFigma will present a choice to the user for which interaction to trigger.
    • bThe prototype will halt due to an interaction conflict error.
    • cOnly the first "On click" interaction in the panel will execute.
    • dBoth interactions will execute in the order they are listed.
    Show the answer

    Answer: c · Only the first "On click" interaction in the panel will execute.

    The card states that Figma's prototyping engine will only execute the first interaction it finds if multiple interactions share the exact same trigger on the same object. It does not execute both, prompt a choice, or halt the prototype.

19. Question 19 of 30

    Which approach lets three profile cards display unique names and avatars in a single reusable overlay frame?

    • aBind the overlay text to a string variable and its avatar to an instance-swap property; set both before opening the same overlay
    • bStore profile data in component properties on the cards and let the overlay inherit them automatically when opened
    • cNest a copy of the overlay inside each profile card and manually edit the name and avatar per copy
    • dCreate three separate overlay frames and open the one matching the clicked profile
    Show the answer

    Answer: a · Bind the overlay text to a string variable and its avatar to an instance-swap property; set both before opening the same overlay

    Setting variables and swapping the avatar instance before opening the same overlay keeps the prototype maintainable and avoids duplication. Creating three separate overlay frames is a tempting but incorrect approach that eliminates reusability.

20. Question 20 of 30

    What is the key architectural difference between a throwaway prototype and a supportable MVP?

    • aAn MVP uses stable interfaces and bounded contexts to allow future replacement of crude implementations
    • bAn MVP is built as a sacrificial architecture that will be discarded once product-market fit is achieved
    • cAn MVP requires multi-region active-active infrastructure from day one, while a prototype does not
    • dAn MVP defers all upfront design and lets architecture emerge purely through iterative development
    Show the answer

    Answer: a · An MVP uses stable interfaces and bounded contexts to allow future replacement of crude implementations

    The correct answer reflects that an MVP must be operationally sustainable and adaptable, which requires lightweight upfront boundaries like stable interfaces, whereas the most tempting distractor—deferring all upfront design—leads to brittle monoliths that collapse under first-scale pressure.

21. Question 21 of 30

    In a Figma prototype for a three-slide carousel, why is it important to configure the last slide so a further left drag does nothing?

    • aSmart Animate requires every frame to have exactly two outgoing triggers or the transition will not animate
    • bWithout an explicit boundary state, users could drag past the last slide into blank space, breaking the illusion of a bounded carousel
    • cFigma automatically loops back to the first slide if a boundary isn't defined, which would confuse users
    • dOn Drag triggers only fire on the first and last frames of a prototype, so boundaries must be set there
    Show the answer

    Answer: b · Without an explicit boundary state, users could drag past the last slide into blank space, breaking the illusion of a bounded carousel

    Without an explicit end state, a drag on the last slide has nowhere defined to go, which lets the user drag into empty space and breaks the bounded feel of the carousel. Figma doesn't auto loop or impose a two trigger rule, those are just plausible sounding assumptions, not real constraints.

22. Question 22 of 30

    A Figma prototype lags specifically when transitioning between screens. Inspection shows a single background image embedded at 6000 pixels wide, reused across forty frames, plus a background blur on every modal. What is the most effective fix?

    • aResize the background image to its actual display resolution and replace the blur with a semi-transparent overlay
    • bConclude the lag is a network issue and have the team switch to a faster wifi connection
    • cRandomly delete a batch of layers throughout the file to shrink its size on disk
    • dLeave the image and blur as they are, since a background image only affects initial load time
    Show the answer

    Answer: a · Resize the background image to its actual display resolution and replace the blur with a semi-transparent overlay

    Oversized embedded images and recomputed effects like blur are GPU costs paid on every interaction, so resizing the image and dropping the blur fixes the real bottleneck. It is not a network problem, and the effect recomputes on every transition, not just at load.

23. Question 23 of 30

    When multiple UI cards reuse the same number variable, how does Figma prevent changing one card's count from affecting another?

    • aIt auto-generates a separate variable behind the scenes for every instance.
    • bIt scopes calculations to the variable mode assigned to each card's parent frame.
    • cIt stores each count as a text layer property instead of a variable value.
    • dIt isolates values by binding each interaction to a unique component variant.
    Show the answer

    Answer: b · It scopes calculations to the variable mode assigned to each card's parent frame.

    The correct answer is B because assigning a mode to each parent frame keeps calculations scoped to that mode context, ensuring independent counters. Distractor A is tempting but wrong because Figma does not auto-generate variables; the designer explicitly creates modes to hold parallel values.

24. Question 24 of 30

    To ensure a conditional navigation in Figma uses a variable's newly updated value within a single interaction chain, which action order is correct?

    • aSet Variable action, then Conditional action.
    • bThe order does not matter as Figma re-evaluates variables before each action.
    • cConditional action, then Set Variable action.
    • dBoth actions execute simultaneously, so their order is irrelevant.
    Show the answer

    Answer: a · Set Variable action, then Conditional action.

    Figma actions execute sequentially from top to bottom. To use an updated variable in a conditional, the Set Variable action must occur first to change the value, followed by the Conditional action which then evaluates the new value. If the conditional runs first, it will check the variable's old value, leading to incorrect behavior.

25. Question 25 of 30

    When planning a remote usability study for rural 3G users, which approach best protects research validity?

    • aThrottle your connection during pilots, use compressed assets in a lightweight prototype, and compensate participants for data costs upfront
    • bBuild a lightweight prototype with local screen recording, but skip data compensation to avoid creating transactional bias in responses
    • cUse uncompressed high-fidelity prototypes with full imagery, rely on cloud-based screen recording, and reimburse participants after the study concludes
    • dDeploy CDN edge nodes near participants, mandate standard video conferencing, and send app-based notifications before each session
    Show the answer

    Answer: a · Throttle your connection during pilots, use compressed assets in a lightweight prototype, and compensate participants for data costs upfront

    This combines testing environment controls, lightweight prototypes, and participant support to protect validity on 2-5 Mbps connections. Option B is the most tempting distractor because it gets the prototype and recording right but fails on data compensation, which the card flags as critical since participants worried about cost will not behave naturally.

26. Question 26 of 30

    A designer is creating a wireframe for a new e-commerce product page. Which detail should they intentionally omit?

    • aLocation of the "Add to Cart" button
    • bThe specific font style for the product title
    • cPlaceholder for the product image
    • dSections for product description and reviews
    Show the answer

    Answer: b · The specific font style for the product title

    Wireframes are intended to map out the structure, layout, and functionality of a UI, not its visual design. Therefore, specific font styles, colors, or branding elements are intentionally omitted. The other options represent structural or functional elements that are core to a wireframe's purpose.

27. Question 27 of 30

    What is the primary mechanism that drives improvements and adaptations in an iterative design process?

    • aRegular analysis of real user interactions and feedback.
    • bAdherence to a detailed, pre-defined project plan.
    • cThe development team's internal brainstorming sessions.
    • dComprehensive market research conducted before any development.
    Show the answer

    Answer: a · Regular analysis of real user interactions and feedback.

    The card emphasizes that iterative design's core is a continuous loop of testing prototypes with real users, observing their interactions, gathering feedback, and then refining the design based on this analysis. Option B describes the 'waterfall' method, which iterative design aims to replace by incorporating early and frequent user feedback.

28. Question 28 of 30

    During the initial ideation phase for a new feature, a design team wants to gather feedback on the core user journey. Which prototyping approach should they avoid to prevent stakeholders from fixating on minor visual elements?

    • aPaper prototypes, as they are too crude to convey a complete user experience.
    • bInteractive mockups with grayscale elements and placeholder text.
    • cLow-fidelity wireframes, which focus solely on layout and information hierarchy.
    • dHigh-fidelity prototypes, due to their realistic appearance and detailed interactions.
    Show the answer

    Answer: d · High-fidelity prototypes, due to their realistic appearance and detailed interactions.

    High-fidelity prototypes should be avoided during early ideation because their realistic appearance can cause stakeholders to fixate on cosmetic details instead of the core workflow. Low-fidelity options like paper prototypes are preferred at this stage as their simplicity encourages feedback on fundamental concepts.

29. Question 29 of 30

    In which situation would a team most appropriately choose to conduct a Design Sprint?

    • aTo replace a lengthy product development phase with a rapid prototyping and launch cycle.
    • bTo quickly implement a series of small, iterative improvements to an existing product.
    • cTo validate a high-risk, novel product concept before committing significant engineering resources.
    • dTo finalize the detailed technical specifications for a well-understood feature.
    Show the answer

    Answer: c · To validate a high-risk, novel product concept before committing significant engineering resources.

    Design Sprints are designed to de-risk high-stakes, uncertain ideas like novel product concepts, allowing teams to get customer feedback before making expensive engineering commitments. They are explicitly not a replacement for the entire product development lifecycle or suitable for small, incremental changes or well-understood problems.

30. Question 30 of 30

    In Figma, how do you prototype a Submit button that enables only after both email and password fields contain text?

    • aCreate string variables for each input, add conditional logic on text change to check both fields are non-empty, then toggle a boolean bound to the button's enabled state.
    • bAdd an on-click interaction to the Submit button that checks the input fields and conditionally allows navigation.
    • cRely on auto-layout and component variant properties alone to detect when text layers are no longer empty.
    • dDuplicate the frame for every input combination and use navigation actions to switch between them as the user types.
    Show the answer

    Answer: a · Create string variables for each input, add conditional logic on text change to check both fields are non-empty, then toggle a boolean bound to the button's enabled state.

    This method uses local variables to store input state and evaluates a conditional expression on every keystroke to toggle a boolean that drives the button reactively. The on-click approach is tempting but wrong because it only validates after the user tries to submit rather than enabling the button dynamically while typing.
