Certified Pega System Architect v8.0 (2019) — Question 1

A customer views a product available in multiple color options. The customer must select only one color for each product.
Which UI control allows a developer to present the user with all color choices at once, without prompting or clicking, while ensuring that the user can only select one of the color options?

Answer options

• A. Radio buttons
• B. Text input
• C. Drop-down
• D. Check box

Correct answer: C

Explanation

The correct answer is C, as a drop-down allows users to see all options at once and select just one. Radio buttons would also allow only one selection, but they do not meet the requirement of displaying all options at once. Text input is not suitable for this scenario as it does not provide predefined options, and check boxes allow multiple selections, which is contrary to the requirement.
