Pega Platform Design · Center-out Business Architecture
A global financial institution is redesigning its loan origination system using Pega Infinity '24. The organization requires a 'Center-out' business architecture to ensure consistency across web, mobile, and API channels. Which design approach best aligns with this requirement?
Answer and explanation
Correct answer: B
Center-out architecture focuses on defining logic (Stages, Steps, Policies) in the Case and Data layers, independent of the channel. Channels (Web, Mobile, API) map to this central logic, ensuring consistency regardless of the entry point.
Question 2
Intermediate
Pega Platform Design · Application Monitoring and Integration
You are architecting a solution involving multiple independent Pega applications (Claims, Policy, Billing) hosted on different Pega versions and clouds. The business requires a unified worklist for adjudicators to view and process assignments from all systems without logging into each individually. Which Pega capability is the optimal architectural choice?
Answer and explanation
Correct answer: B
Pega Process Fabric is designed specifically to federate work from distributed Pega (and non-Pega) applications into a single unified worklist and dashboard, decoupling the worker experience from the underlying application versions.
Question 3

Pega Platform Design · Deployment Architecture
A Pega Cloud application running on Kubernetes is experiencing 'Split-Brain' issues where nodes lose visibility of each other, causing duplicate agent processing. Which component's configuration should be investigated first to resolve this clustering instability?
Answer and explanation
Correct answer: C
Pega uses Hazelcast for in-memory clustering and node-to-node communication. In a Kubernetes environment, misconfiguration of Hazelcast (e.g., incorrect service discovery or network policies blocking port 5701) is the primary cause of split-brain scenarios.

Pega Platform Design Extended · UX Design and GenAI
An organization plans to implement Pega GenAI to accelerate workflow creation. Which Pega tool allows architects to describe the application requirements in natural language and automatically generates the case lifecycle, data objects, and persona definitions?
Answer and explanation
Correct answer: A
Pega GenAI Blueprint is the specific tool that leverages generative AI to transform natural language descriptions into a structural application design (Case Types, Data, Personas) which can then be imported into Pega Platform.
Question 5
Advanced
Pega Platform Design · Deployment Architecture
A Lead System Architect is designing a high-volume transaction system. The requirement is to process approximately 50,000 requests per minute. The LSA decides to externalize the Kafka configuration rather than using the embedded Pega Stream Service. What is the primary architectural justification for this decision?
Answer and explanation
Correct answer: B
While embedded Kafka works for many use cases, high-volume/enterprise scenarios benefit from external Kafka to isolate resource consumption (CPU/Memory/Disk I/O) from the Pega nodes and to leverage enterprise-grade scaling and retention capabilities.
Question 6
Intermediate
Pega Platform Design Extended · UX Design and GenAI
You are designing a Pega application that utilizes the Constellation UI architecture. Which statement accurately describes a constraint or characteristic of this architecture compared to the traditional Section-based UI?
Answer and explanation
Correct answer: B
Constellation moves away from server-rendered HTML (Section-based). It sends metadata via DX API to a client-side engine, which enforces design system consistency. This means custom HTML/JSP sections are generally not supported or require specific custom components.
Question 7
IntermediateMultiple answers
Pega Platform Design · Application Monitoring and Integration
Select TWO valid use cases for implementing Pega Intelligent Virtual Assistant (IVA) in an enterprise application. (Select TWO)
Answer and explanation
Correct answers: A, C
IVA provides connectors for social messaging platforms, allowing case interaction via chat.
Email Bots (a form of IVA) use NLP to understand email content, extract data (entities), and automate case creation/routing.
Question 8
Beginner
Pega Platform Design Extended · Studio Tools Adoption
Which Pega Studio is primarily designed for data scientists to configure adaptive models and monitor the effectiveness of AI predictions within the Customer Decision Hub context?
Answer and explanation
Correct answer: C
Prediction Studio is the dedicated workspace for managing AI models, predictive analytics, and text analytics configurations.

Pega Platform Design Extended · Studio Tools Adoption
During a system outage, several Queue Processor items failed and moved to the 'Broken-Process' state. Which tool in Admin Studio allows an administrator to inspect the error messages and requeue these items for processing?
Answer and explanation
Correct answer: B
The Queue Management landing page in Admin Studio provides visibility into Queue Processors, allowing admins to view status, inspect broken items, and trace or requeue them.
Question 10

Application Design · Specialization Strategies
A multinational corporation needs to implement a 'Know Your Customer' (KYC) application. The core process is identical globally, but the data collection requirements and validation rules differ significantly for the 'Retail' vs. 'Corporate' lines of business, and further vary by 'Region' (NA, EMEA, APAC). Which specialization strategy provides the most maintainable and scalable architecture?
Answer and explanation
Correct answer: B
For structural differences and significant variations in data/logic across multiple dimensions (LOB and Region), Class Specialization (often via the Situational Layer Cake) is superior to circumstancing. It allows for distinct class-based inheritance, better reuse, and easier maintenance of complex variations.
