Question 1

What are the core stages of modern enterprise CI/CD architecture?

Accepted Answer

Modern CI/CD architecture consists of 5 core stages: continuous code integration via git triggers, automated unit and lint testing, artifact containerization with security vulnerability scanning, staging orchestration in ephemeral environments, and blue-green or canary production deployment with automated telemetry health gates.

Question 2

How do automated testing gates prevent production deployment failures?

Accepted Answer

Automated testing gates block pipeline progression if unit test coverage drops below thresholds, if static analysis detects security flaws, or if performance regression tests detect latency degradation. By isolating defects in staging, failure rates drop by over 85%.

Question 3

What is the recommended rollback strategy for continuous delivery in 2026?

Accepted Answer

The industry standard is immutable artifact versioning paired with blue-green routing or automated feature flag toggles. If real-time synthetic monitoring detects elevated error rates post-deploy, traffic automatically reverts to the previous stable release in under 60 seconds.
