Changes

Learning-Path Level (NEW)

• automation-and-reliability/test.md: Added 10 comprehensive questions covering both Observability and CI/CD concepts to ensure the learning-path level has test coverage

Introduction to Observability Module

• observability/test.md: Enhanced from 7 to 12 questions covering trace components, observability tools (Jaeger, Zipkin, Meshery), data volume challenges, and system metrics
• Module-level test.md: Enhanced from 4 to 8 questions covering DevOps integration, Alert Fatigue, and comprehensive pillar assessment

CI/CD Module

• cicd/test.md: Enhanced from 10 to 14 questions covering CI principles (frequent integration, automated builds/testing), Continuous Deployment characteristics, phased rollout strategies, and GitOps principles (declarative config, single source of truth, pull-based reconciliation)
• Module-level test.md: Enhanced from 4 to 8 questions covering CI/CD benefits, release strategies (Blue-Green, Canary, Feature Toggles), and deployment model distinctions

Test Coverage Summary

• Total Questions: 72 (10 Learning-path + 30 Observability + 32 CI/CD)
• New Questions Added: 27 (10 learning-path + 17 module enhancements)
• Question Types: Only single-answer and multiple-answers (no short-answer)
• Pass Percentage: Maintained at 70% across all tests
• Coverage: 100% - All learning-paths (1/1), courses (2/2), and modules (6/6) have tests

All questions are directly derived from module content, ensuring alignment with learning objectives.
