Appian Senior Developer (ACD101) — Question 10

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?

Answer options

• A. An interface, because the component must render user interface elements.
• B. An expression rule, because the component captures expressions of user sentiment for analysis.
• C. A 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.

Correct answer: A

Explanation

The correct answer is A, as an interface is necessary to create and render user interface elements like icons. Option B is incorrect because an expression rule is not designed for rendering UI components, and option C is also wrong because a decision is not the appropriate object type for displaying icons in a toolbar.
