Pega Senior System Architect (PCSSA) Exam 2026/2027 |
Complete Practice Questions, Correct Answers & Detailed
Rationales
SECTION 1 — APPLICATION DEVELOPMENT & ARCHITECTURE
1. What is the primary purpose of an enterprise class structure in
Pega?
A. To define database indexes
B. To promote reuse across applications
C. To configure user passwords
D. To manage email templates
Answer: B
Rationale: An enterprise class structure organizes applications and
reusable rules so functionality can be shared across multiple lines of
business.
2. A company has several applications that share customer-
management functionality. What is the best architectural approach?
A. Duplicate the functionality in every application
B. Place common functionality in a reusable layer
C. Create separate databases for each application
D. Put all functionality into one case type
Answer: B
Rationale: A reusable architecture minimizes duplication and makes
shared functionality easier to maintain.
3. Which architecture best supports enterprise reuse?
,A. Copy-and-modify development
B. Modular layered architecture
C. Single-class architecture
D. Database-only architecture
Answer: B
Rationale: Modular layered architecture separates reusable capabilities
from application-specific functionality.
4. What is a major benefit of modular application architecture?
A. It eliminates all rules
B. It encourages reuse and maintainability
C. It prevents application versioning
D. It removes security requirements
Answer: B
Rationale: Modular architecture allows components to be reused and
maintained independently.
5. Which component typically contains rules shared by multiple
applications?
A. Enterprise or framework layer
B. Browser cache
C. Work queue
D. Clipboard page
Answer: A
Rationale: Shared rules are commonly placed in reusable enterprise or
framework layers.
6. What is the primary purpose of the New Application wizard?
,A. To create a database backup
B. To accelerate application creation and configuration
C. To encrypt case attachments
D. To debug JavaScript
Answer: B
Rationale: The wizard provides a guided approach for creating the
initial application structure.
7. Which principle should guide an architect deciding where to place
reusable rules?
A. Put everything in the highest application layer
B. Place functionality at the lowest appropriate reusable layer
C. Put every rule in the implementation layer
D. Duplicate shared rules
Answer: B
Rationale: Placing reusable functionality at the appropriate lower layer
maximizes reuse while preserving specialization.
8. What does rule resolution determine?
A. Which user receives an email
B. Which rule instance Pega uses at runtime
C. Which database stores attachments
D. Which browser is supported
Answer: B
Rationale: Rule resolution evaluates available rule instances and
determines the rule used by the application.
9. Which factor can affect rule availability?
, A. Ruleset configuration
B. Monitor brightness
C. Browser window size
D. User's keyboard layout
Answer: A
Rationale: Ruleset configuration and related rule metadata affect which
rules are available during resolution.
10. A rule is available in a higher layer and another version exists in a
lower layer. Which principle is important when troubleshooting?
A. Ignore class hierarchy
B. Understand rule resolution and inheritance
C. Restart every browser
D. Delete the higher-level rule
Answer: B
Rationale: Rule resolution depends on hierarchy, availability, and other
rule-selection factors.
11. What is the main advantage of designing for reuse?
A. More duplicated code
B. Lower maintenance effort
C. Fewer application layers
D. Elimination of testing
Answer: B
Rationale: Reusable components reduce duplication and simplify future
maintenance.
