Use this topic map to guide your study for Pegasystems PEGACPLSA23V1 (Certified Pega Lead System Architecture (LSA) Exam 23) within the Pega Lead System Architect path.
PEGACPLSA23V1 uses multiple question formats to assess both conceptual knowledge and practical decision-making. The exam measures your ability to analyze complex scenarios, apply architectural principles, and justify design choices in real-world contexts.
Questions progress in difficulty, requiring deeper reasoning as you advance. Success depends on understanding not just "what" features exist, but "why" and "when" to apply them in enterprise contexts.
Build a structured study plan that maps each topic to dedicated weeks and includes regular practice and review. Effective preparation balances theoretical understanding with hands-on application, ensuring you can confidently make architectural decisions under exam conditions.

Pega Platform Design, Application Design Extended, and Data Model Design typically represent the largest portion of the exam. However, all six domains are equally important for demonstrating competency as a Pega Lead System Architect. Balance your study across all topics while allocating extra time to areas where you have less hands-on experience.
In practice, these domains work together: Pega Platform Design sets the foundation, Application Design Extended structures the solution, Data Model Design supports performance and reporting, Reporting Design delivers business insights, Security Design protects assets, and Deployment and Testing Design ensures production readiness. Understanding these connections helps you design cohesive solutions and answer scenario-based questions more effectively.
The exam is designed for architects with significant Pega experience, typically 3+ years in system design roles. Hands-on experience with data modeling, application configuration, and deployment is valuable. If you lack experience in specific areas, use practice tests and study materials to build conceptual knowledge, then seek opportunities to apply those concepts in real projects or lab environments.
Candidates often overlook the "why" behind design decisions and focus only on features. Scenario-based questions require you to evaluate trade-offs; choosing a technically correct feature that doesn't fit the business context leads to wrong answers. Additionally, rushing through questions without carefully reading all options and understanding the specific constraint or objective in each scenario is a frequent pitfall.
Focus on weak areas identified in practice tests rather than re-reading all study materials. Take one full-length timed practice test to validate pacing and identify remaining gaps. Review architectural patterns and decision frameworks for each domain. Avoid cramming new topics; instead, consolidate your understanding and build confidence in areas where you already have solid knowledge.
