Certified Pega System Architect v7.2 — Question 19

You have been asked to create a sequence of user forms for a travel reservation process. The forms contain fields that require calculation. For which reason do you use a declare expression to calculate values?

Answer options

• A. To perform the calculation in a specific case stage
• B. To perform the calculation when the user clicks a button
• C. To perform the calculation when a form is submitted
• D. To perform the calculation wherever a field is updated

Correct answer: A

Explanation

The correct answer is A because a declare expression is specifically used to calculate values at a defined stage in the case processing. Options B and C suggest interactions that occur at specific user actions, while D implies real-time calculation, which is not the intended use for a declare expression.
