Appian ACD101 Exam - Topic 4 Question 37 Discussion

Actual exam question for Appian's ACD101 exam

Question #: 37
Topic #: 4

A customer wants to display a small toolbar with three icons - a "sad face," a "face with neutral expression," and a "happy face" - on the bottom of every page in their application.

Users will be instructed to use the icon that best expresses their current experience using the application. This will allow the customer to collect valuable data about users.

Which object type should be called from each page to implement this feature?

AAn interface, because the component must render user interface elements.

BAn expression rule, because the component captures expressions of user sentiment for analysis.

CA decision, because the component captures a choice that users select from an array of custom selection components, rather than a standard dropdown or radio button.

Show Suggested Answer

Suggested Answer: A

In Appian, interfaces are used to design and render user interface elements, allowing for the creation of custom layouts and components that can interact with users. In this scenario, the toolbar with emotion icons is a UI element that needs to be consistently presented across various pages. Using an interface ensures that these icons can be interactively used by users to express their sentiments, and the data collected can be analyzed for user experience insights. Interfaces are capable of embedding such UI elements and can be invoked or included across multiple pages within an application, making them the ideal choice for this requirement. Reference:

Appian Documentation on Interfaces: Provides detailed guidance on how to design and use interfaces to create user-centric UI components.

Wait, can we really capture emotions like that? Sounds tricky!

Really? An expression rule seems more fitting for sentiment analysis.

I feel like we practiced a similar question, but I can't recall if it was about interfaces or expressions.

This kind of sounds like a decision component to me, since users are making a choice based on their feelings.

I'm not entirely sure, but I remember something about expression rules being used for capturing user feedback.

I think we might need to use an interface since it involves rendering those icons on the page, right?

This is a tricky one. I can see arguments for both the interface and expression rule options. I might try to get some clarification from the instructor on whether the focus is more on the UI presentation or the data collection aspect. That could help me decide between A and B.

I think the key here is that the toolbar is capturing user sentiment, which suggests a more analytical component rather than a pure UI one. So I'd probably go with option B, the expression rule, as that seems to best fit the stated purpose of collecting data on user experience.

Hmm, I'm a bit confused on this one. The question mentions rendering user interface elements, so I'm not sure if an expression rule is the right choice. I might lean more towards option A, an interface, since that seems to align better with the UI-focused nature of the requirement.

This seems like a straightforward question. I'd approach it by thinking about the core functionality - the toolbar needs to display different icons based on user input. So I'd probably go with option B, an expression rule, since that seems to capture the essence of what the component is doing.

Haha, this question is like a multiple-choice version of 'which emoji best represents how you're feeling right now?' I'd go with C.

Hmm, I'm not sure. I guess B could work, but I'm leaning towards C since the question mentions the component is capturing a 'choice' from users.

I see your point, Chantell. But I think C) A decision makes more sense, as it involves capturing user choices from custom selection components.

I disagree, I believe the correct answer is B) An expression rule, as it captures user sentiment for analysis.

C seems like the right answer. The component is allowing users to choose from a custom set of icons, which is more like a decision than an interface or expression rule.
