CPSA Data Modeling & Integration Techniques 2 — Questions and Answers
Question 1: In Pega, which property mode should you use when a single case can have multiple addresses, each with street, city, and zip fields?
- Single Value
- Page
- Page List (Correct answer)
- Value List
Correct answer: Page List
Page List mode stores a list of embedded pages, making it ideal for repeating groups of related fields like multiple addresses.
Question 2: A Pega application must retrieve customer data from an external REST API and map the response to a Pega data page. Which component defines the structure of the external response?
- Data Transform
- Connector
- Response Data Transform (Correct answer)
- Activity
Correct answer: Response Data Transform
The Response Data Transform maps the REST connector's response payload fields to the Pega clipboard page structure.
Question 3: When configuring a data page with 'System' scope in Pega, when is the data refreshed?
- Every time any user accesses the data page
- Once per node and shared across all users and requestors (Correct answer)
- Once per user session
- Once per case instance
Correct answer: Once per node and shared across all users and requestors
System-scoped data pages load once per node and are shared across all users, minimizing redundant data fetches for common reference data.
Question 4: Which Pega feature allows you to define a reusable set of properties and behaviors that can be inherited by multiple classes?
- Data Page
- Class Group
- Abstract Class (Correct answer)
- Property Set
Correct answer: Abstract Class
Abstract classes in Pega define shared properties and rules that concrete subclasses inherit, promoting reuse and reducing duplication.
Question 5: In Pega's layered architecture, which layer should contain enterprise-wide data model properties shared across all applications?
- Implementation layer
- Division layer
- Organization layer (Correct answer)
- Framework layer
Correct answer: Organization layer
The Organization layer sits at the top of the ruleset hierarchy and houses enterprise-wide rules and properties accessible to all applications.
Question 6: A developer needs to call a SOAP web service from a Pega case. What rule type is used to define the SOAP endpoint and operation?
- REST Connector
- SOAP Connector (Correct answer)
- Integration Service
- Service Activity
Correct answer: SOAP Connector
A SOAP Connector rule in Pega defines the WSDL endpoint, operation, and message structure for consuming SOAP web services.
Question 7: Which Pega data model best practice recommends embedding a page property directly in the case class rather than storing it in a separate database table?
- Normalization
- Embedding for performance (Correct answer)
- Data federation
- Class hierarchy flattening
Correct answer: Embedding for performance
Embedding pages avoids additional database joins and improves read performance for data that is always accessed together with the parent case.
