CPSA - Certified Pega System Architect Data Modeling and Properties Questions and Answers

Question 1

A developer needs to model a data structure to hold a list of vehicles associated with a customer. Each vehicle has a make, model, and year. The number of vehicles per customer varies. Which property mode is most appropriate for this requirement?

Accepted Answer

Page List

Answer

A Page List is the correct choice because it represents an ordered list of pages, where each page can represent a single vehicle with its own properties (make, model, year). This allows for a variable number of vehicles to be associated with the customer.

Question 2

In a Pega application, a developer is building a case type for loan applications. The application needs to store the primary applicant's information, including their full name, date of birth, and address. The address itself is a complex data object with properties for street, city, state, and zip code. How should the address information be modeled within the applicant's data structure?

Accepted Answer

As a Single Page property.

Answer

A 'Page' property is the ideal way to model the address. It encapsulates a group of related properties (street, city, etc.) into a single, logical object. This promotes reuse and better data organization compared to adding individual properties for each address field directly to the applicant data model.

Question 3

Which of the following is considered a Pega best practice for naming data properties to avoid redundancy?

Accepted Answer

Using a property name that is concise and does not repeat the context of its owning class.

Answer

Pega best practices advise against redundant naming. If a property 'StartDate' exists within a data class named 'Event', it is unnecessary to name the property 'EventStartDate'. The context is already understood from the class, so the concise name 'StartDate' is preferred.

Question 4

A business requirement states that a user's entered phone number must conform to a specific format (e.g., (###) ###-####). Which type of rule is most suitable for enforcing this specific format validation on the property itself?

Accepted Answer

An Edit Validate rule

Answer

An Edit Validate rule is used for client-side, format-based validation of a single property. It typically uses Java to define a specific pattern, like a phone number or postal code format, and returns true or false.

Question 5

When is it preferable to use a Data Transform instead of an Activity for data manipulation?

Accepted Answer

When setting default values, copying pages, or mapping data between objects.

Answer

Data Transforms are the preferred, lightweight mechanism for common data manipulation tasks like setting initial property values, copying data from one page to another, and mapping values. Activities are more powerful but are resource-intensive and should be reserved for more complex operations like background processing or integrations where no other rule type is sufficient.
