[Performance Optimization]
A company is implementing field-level auditing in their application. What two scenarios can affect the field-level auditing feature in an application? (Choose Two)
Correct Answer:
A, D
Explanation
Field-level auditing tracks changes to individual fields in your application. When you have many fields to audit, the system has to monitor and log more changes, which increases overhead and can impact performance. Similarly, fields that change frequently generate many audit records, creating database load and slowing down queries. Both scenarios increase the volume of audit data the system must process and store, making them key factors that affect auditing performance.
[Application Design]
An application design team led by a Lead System Architect is considering the divide-and-conquer approach for most business use cases. Which two of the following reasons are benefits behind the team's decision to use the divide-and-conquer design pattern? (Choose Two)
Correct Answer:
B, C
Explanation
The divide-and-conquer approach breaks complex problems into smaller, manageable pieces. This lets different team members work on separate components at the same time, which improves resource allocation and project speed. It also reduces dependencies between teams and makes it easier to test and maintain individual parts. Breaking work into focused units means each team can develop expertise in their area and reduces the complexity any single person has to manage.
[Pega Platform Architecture]
As a Lead System Architect, it is crucial to understand the technical landscape of an organization. Which are two benefits that you can derive from this understanding? (Choose Two)
Correct Answer:
A, B
Explanation
A Lead System Architect needs to understand the technical environment to make informed design decisions. Knowing the existing systems and infrastructure helps speed up development because you can reuse proven approaches and avoid common pitfalls. It also helps you design proper interfaces and integration points that work with what the organization already has. This understanding prevents rework and ensures your Pega application fits well into the broader technical ecosystem.
[Performance Optimization]
An online streaming service faces performance issues because of a high volume of user data stored in the database. As a Lead System Architect, what are the two best corrective actions that you suggest for enhancing application performance? (Choose Two)
Correct Answer:
B, D
Explanation
High database volume slows down queries and transactions. Archiving old cases and purging historical data removes unused records from active tables, making queries faster. Indexing critical columns tells the database how to find data more quickly, which improves query performance without removing data. Together these approaches reduce the amount of data the system must search through on each request. Database optimization and data housekeeping are standard practices for maintaining performance as applications grow.
[Deployment and Testing]
You are a Pega developer working on a large project. You must implement custom guardrail warnings to ensure that the team follows certain coding standards. Which two of the following statements about custom guardrail warnings are true? (Choose Two)
Correct Answer:
A, B
Explanation
Custom guardrail warnings are rules in Pega that alert developers when their code doesn't follow team standards. They trigger based on conditions you define, such as when someone uses a particular coding pattern or violates a naming convention. This enforcement helps maintain consistency across your codebase and catches issues early in development. Guardrails work automatically during development, so they catch problems before code goes to production rather than waiting for manual review.
[Integration]
Every day at 1 AM, all the ATM transactions at ABC Bank from the previous day are shared with the head office of the bank. All ATM machines perform this data sharing. ABC Bank uses this information to validate transactions and balance all the ledgers. If any discrepancy is identified, a dispute resolution flow initiates to investigate the root cause and resolve the dispute. ABC Bank has 1 million ATMs for which transactions need to be analyzed for discrepancies. Which one of the following is the optimal solution for gathering the transaction information from all the ATMs?
Correct Answer:
D
Explanation
A function alias allows you to categorize continuous data like shopping duration into discrete buckets or ranges for reporting. Using a function alias in your report lets you segment customers into the four shopping history categories without requiring complex query rewrites. Other approaches like custom queries or additional data tables would be more complex and less efficient for simple range-based categorization of report data.
[Security Design]
What are the primary uses of the Rule Security Analyzer in Pega Platform? (Choose Two)
Correct Answer:
C, D
Explanation
The Rule Security Analyzer is a Pega tool that scans your application rules to find security problems. It checks whether rules follow security best practices and identifies rules that might have vulnerabilities, such as missing authentication checks or improper access controls. The tool automates the process of finding these issues so you don't have to manually review every rule. This helps ensure your application meets security standards before it goes to production.

FAQ
PEGACPLSA23V1 Exam FAQ
Common questions about the exam itself
What background do I need to take the PEGACPLSA23V1 exam?
You must be a Certified Pega Senior System Architect with at least 36 months of field experience. This is a Lead System Architect level certification, not an entry-level exam, so the prerequisite reflects the advanced knowledge expected.
How hard is the PEGACPLSA23V1 exam and how long should I prepare?
This is an advanced certification exam testing complex enterprise architecture decisions. Most candidates with the required background spend 4 to 8 weeks preparing, focusing on real-world design scenarios and the specific objective areas where they have less hands-on experience.
Which objective area is the hardest in PEGACPLSA23V1 and how should I approach it?
Security Design and Application Design Extended tend to be the most challenging because they require understanding multiple interconnected design decisions. Build your knowledge by working through case studies that involve end-to-end security implementations and complex workflow scenarios.
What is the passing score for PEGACPLSA23V1?
The official passing score is published on the Pega Academy exam page, and you should verify the current passing score when you register for the exam as it may be updated. Most Pegasystems architecture exams require between 65% and 75% to pass.
How is the PEGACPLSA23V1 exam delivered?
The exam is proctored by Pearson VUE and you can take it online with remote proctoring from your home or office, or at a physical Pearson VUE testing centre. You will have 120 minutes to complete 60 questions that include multiple choice, scenario-based questions, and drag-and-drop items.
What are the retake and rescheduling rules for PEGACPLSA23V1?
You can take PEGACPLSA23V1 up to three times in a 12-month period starting from your first attempt. After failing, you must wait three calendar days before a second attempt and fourteen calendar days before a third attempt. Rescheduling is allowed with fees.
How long does the Pega Lead System Architect certification stay valid?
Pega certifications do not expire. Once you earn your CPLSA certification, it remains active indefinitely. However, Pegasystems periodically releases new versions of exams, and you may want to stay current with the latest platform version.
What job role does PEGACPLSA23V1 prepare you for?
This certification prepares you for a Lead System Architect role, where you would guide large-scale Pega implementations, make critical architecture decisions, and mentor other system architects on design best practices.
Where does PEGACPLSA23V1 fit in the Pega certification track?
PEGACPLSA23V1 is the first exam in the Certified Pega Lead System Architect certification journey. After passing this architecture exam, you must also pass two additional exams: the Application Design exam and the Application Build exam to complete the full CPLSA certification.
Can I use Pega Express patterns and microjourney concepts on the job after passing PEGACPLSA23V1?
Yes. This exam covers Pega Express best practices and microjourney analysis as design foundations, so the patterns and approaches you study are directly applicable to real-world application design work you will do as a Lead System Architect.
