CPSA Cross-cutting Concepts 2

Question 1

Which cross-cutting concept ensures that all system components record events in a consistent, correlated manner for troubleshooting?

Accepted Answer

Distributed tracing

Answer

Distributed tracing correlates log events across services using shared trace IDs, enabling end-to-end troubleshooting in distributed systems.

Question 2

In iSAQB CPSA, which term describes technical concepts that affect multiple components or layers without belonging exclusively to any single one?

Accepted Answer

Cross-cutting concerns

Answer

Cross-cutting concerns are aspects like logging, security, and caching that span multiple architectural elements and cannot be cleanly encapsulated in one module.

Question 3

A system must validate user roles on every REST endpoint. Which cross-cutting mechanism is most appropriate?

Accepted Answer

Middleware or interceptor pipeline

Answer

Middleware or interceptor pipelines apply cross-cutting logic such as authorization to every request without scattering that logic across individual endpoint handlers.

Question 4

Which strategy best addresses consistency of error responses across all services in a microservices architecture?

Accepted Answer

Defining a shared error response schema and enforcing it via an API gateway

Answer

A shared error response schema enforced at the API gateway ensures uniform error handling that clients can rely on regardless of which backend service responded.

Question 5

What is the primary architectural reason for externalizing configuration (e.g., feature flags, connection strings) from application code?

Accepted Answer

To allow environment-specific behavior without rebuilding artifacts

Answer

Externalizing configuration decouples deployment artifacts from environment-specific values, enabling the same build to run in dev, staging, and production.
