Pega Lead System Architect (CPLSA) Exam 2026/2027 |
Architecture Practice Questions, Answers & Detailed
Rationales
SECTION 1 — Pega Platform Architecture & LSA Mindset
Questions 1–40
1. What is the primary responsibility of a Pega Lead System Architect?
A. Configure individual UI fields
B. Design and guide the overall Pega solution architecture
C. Write every application rule personally
D. Manage only production incidents
Answer: B
Rationale: The LSA is responsible for the overall technical architecture
and guides implementation decisions across the solution. The role
emphasizes maintainability, scalability, performance, security, and
business value.
2. Which architectural principle best supports an enterprise Pega
implementation?
A. Duplicate functionality for every business unit
B. Centralize all rules in one class
C. Build reusable capabilities around shared business concepts
D. Avoid application layering
Answer: C
,Rationale: Reusable capabilities reduce duplication and make
enterprise solutions easier to extend and maintain.
3. What is the primary purpose of Center-out business architecture?
A. Replace all enterprise systems
B. Establish reusable business capabilities at the center and expose
them through channels
C. Store all application data in one database
D. Eliminate integrations
Answer: B
Rationale: Center-out architecture focuses on reusable business
capabilities and services that can be consumed consistently by multiple
channels and applications.
4. A company has several applications implementing nearly identical
customer verification logic. What should an LSA recommend?
A. Copy the rules into each application
B. Create reusable shared capabilities
C. Put all logic in UI scripts
D. Duplicate the database tables
Answer: B
Rationale: Shared business capabilities reduce duplication and promote
consistent behavior across applications.
,5. Which factor should be considered first when choosing an
architectural approach?
A. Developer preference
B. Business and technical requirements
C. Number of screenshots
D. Color scheme
Answer: B
Rationale: Architecture must be driven by business objectives,
functional requirements, nonfunctional requirements, and enterprise
constraints.
6. Which requirement is an example of a nonfunctional requirement?
A. Customer submits an application
B. Manager approves a request
C. Application supports 5,000 concurrent users
D. Customer receives a confirmation
Answer: C
Rationale: Scalability and concurrency are nonfunctional requirements
describing how the system must perform rather than what business
process it performs.
7. A solution must support future regulatory changes without major
redevelopment. Which architectural quality is most important?
, A. Built for change
B. Maximum duplication
C. Hard-coded business logic
D. Single-use components
Answer: A
Rationale: Designing for change means isolating volatile business rules
and using reusable, configurable architecture.
8. What should an LSA do when two possible designs both satisfy
functional requirements?
A. Select the design with the fewest considerations
B. Compare trade-offs against business and nonfunctional requirements
C. Always select the newest feature
D. Always select the shortest implementation
Answer: B
Rationale: Architecture is about evaluating trade-offs involving
maintainability, performance, security, scalability, cost, reuse, and
future change.
9. Which characteristic most strongly indicates a good enterprise
architecture?
A. Large number of custom rules
B. Minimal reuse
C. Clear separation of responsibilities
D. Maximum customization
