PEGACPLSA25V1 Exam Topics at a Glance

The exam is balanced across three major architecture areas: Infrastructure and Architecture, Planning and Design, and Implementation and Deployment, each representing 30% of the exam. Constellation Adoption accounts for the remaining 10%.

Infrastructure and Architecture

Exam Weight: 30%

This domain focuses on enterprise architecture principles and how to design Pega solutions for large and complex organizations. Candidates should understand how Pega fits into an enterprise IT landscape, how deployment architecture works as a clustered and distributed system, and how node types, tiers, and failover concepts affect enterprise deployment decisions.

Key areas include:

• Enterprise architecture principles
• Pega deployment architecture
• Clustered and distributed system design
• Node roles, tiers, and node types
• High availability, resiliency, and failover
• Enterprise security concepts
• Architectural trade-offs for performance and scalability
• Pega GenAI architecture and responsible AI adoption
• Service externalization using services and APIs
• Event-driven architecture with Kafka
• System monitoring and operational resilience

This section is important because Lead System Architects must design solutions that remain scalable, secure, maintainable, and aligned with enterprise standards.

Planning and Design

Exam Weight: 30%

The Planning and Design domain validates your ability to structure Pega applications correctly from the beginning. Candidates should understand application stack design, ruleset organization, layer responsibilities, case hierarchy, specialization, data modeling, integration design, authentication, authorization, and operational visibility.

Key areas include:

• Application stack design
• Ruleset and layer organization
• Case hierarchy and subcase decisions
• Reuse and parallel development
• Specialization strategies
• Data persistence and reference data
• REST-based integration design
• Decoupling and external system interaction
• OIDC and identity provider design
• Security and access control planning
• Pega Predictive Diagnostic Cloud planning
• Monitoring and supportability considerations

This domain tests whether candidates can translate business requirements into a flexible application design that supports future change.

Implementation and Deployment

Exam Weight: 30%

This domain focuses on delivering production-ready Pega solutions. Candidates should understand background processing, asynchronous execution, queue processors, work assignment models, routing, web embed interfaces, deployment planning, CI/CD pipelines, secure implementation practices, and production readiness.

Key areas include:

• Background processing design
• Queue processor usage
• Asynchronous case and workload handling
• Assignment routing to users, teams, and work queues
• Landing pages and role-based user productivity
• Web embed implementation considerations
• Release management
• CI/CD deployment pipelines
• Multi-team development support
• Rollback readiness
• Secure-by-design implementation
• Compliance and auditability
• Post-deployment supportability

This section is practical because Lead System Architects must guide teams through implementation choices that affect stability, release quality, and operational success.

Constellation Adoption

Exam Weight: 10%

Constellation Adoption focuses on Pega's modern UI and design system. Candidates should understand the Constellation architecture, the separation of workflow and presentation, the relationship between case type data models and field types, and the use of Views instead of traditional sections and flow actions.

Key areas include:

• Constellation architecture
• Workflow and presentation separation
• Case Type Data Model and field types
• View-based UI authoring
• Simple, partial, and complex Views
• Primary Fields and Case tabs
• Constellation troubleshooting approaches
• Coexistence between Traditional UI and Constellation
• Incremental Constellation adoption planning

This domain is especially important for candidates working with modern Pega Platform '25 applications or planning migration from Traditional UI to Constellation.

CPLSA Certification Path

The PEGACPLSA25V1 exam is not the only requirement for CPLSA certification. Pega states that candidates must complete a two-part examination process: first the Pega Lead System Architect Exam, then the CPLSA Application Design and Build Exam.

The Application Design and Build assessment evaluates whether candidates can architect, implement, and analyze solutions using Pega Platform. Starting with the Pega Infinity '25 version, Pega describes the assessment as a single-phase exam in which candidates design, build, and submit an application for evaluation.

How to Prepare for the PEGACPLSA25V1 Exam

1. Review the Official Exam Domains

Start with the four main domains: Infrastructure and Architecture, Planning and Design, Implementation and Deployment, and Constellation Adoption. Since the first three domains each represent 30% of the exam, they should receive most of your study time.

2. Strengthen Enterprise Architecture Thinking

This is an advanced Pega architecture exam, so focus on design decisions, trade-offs, governance, scalability, security, performance, and maintainability. Practice thinking like a Lead System Architect who must guide teams and defend architecture choices.

3. Study Pega Platform '25 Capabilities

Review Constellation, Pega GenAI, service externalization, event-driven architecture, background processing, queue processors, CI/CD, PDC, OIDC, identity providers, and modern deployment considerations.

4. Practice Scenario-Based Questions

The exam focuses on architecture judgment, not basic feature memorization. Practice questions should help you decide when to use specific Pega design patterns, how to structure applications, how to handle enterprise integrations, and how to support production readiness.

5. Use Valid PEGACPLSA25V1 Practice Test Questions

Valid PEGACPLSA25V1 Practice Test Questions from PassQuestion can help candidates understand exam-style scenarios, reinforce important concepts, and identify weak areas before the real exam. Practice questions are especially useful for application architecture, case design, integration planning, deployment strategy, Constellation adoption, security, performance, and governance topics.
