Continuous Integration and Delivery Pipelines Questions
Design and implement continuous integration and continuous delivery pipelines that reliably build, test, validate, and deploy applications and infrastructure. Topics include pipeline as code practices, defining stages and triggers for builds and tests, automated testing strategies across unit, integration, smoke, and end to end tests, gating and environment promotion, branching and release strategies, artifact management and versioning, and deployment patterns such as rolling updates, blue green deployments, and canary releases. Candidates should be able to design rollback and recovery procedures, integrate infrastructure provisioning into pipelines, select and configure pipeline tooling such as Jenkins, GitHub Actions, GitLab CI, Azure Pipelines, or cloud vendor pipeline services, and reason about observability and reporting for pipeline health and test execution. Practical considerations include environment parity, pipeline security, secrets handling, pipeline as code best practices, and trade offs between speed and safety.

How would you implement compliance and auditing controls in CI/CD pipelines for a regulated industry (e.g., healthcare or finance)? Discuss immutable logs, signed artifacts, role-based approvals, evidence packaging for auditors, and how to make pipelines auditable without blocking developer velocity.

Design an environment promotion workflow dev → integration → staging → production. Include automated gates (lint, unit, smoke, integration, security scans), manual approvals, artifact immutability, and how to implement artifact pinning by digest. Describe rollback options if promotion gates fail in staging or prod.

A client asks you to recommend a CI/CD platform for a hybrid environment (on-premise + AWS), ~500 developers, enterprise secret management, external integrations, and constrained OPEX. Compare Jenkins, GitLab CI, GitHub Actions, and a managed cloud pipeline service (e.g., AWS CodePipeline) and justify a recommendation including migration considerations.

As a Solutions Architect, design a CI/CD pipeline that enforces software supply chain security: generate and store SBOMs, sign artifacts, perform vulnerability scanning and provenance tracking, and provide push-button remediation and rollback. Describe incremental rollout steps to integrate these controls into an existing pipeline and discuss performance trade-offs.

List practical best practices for pipeline-as-code that you would recommend to a client: modularization of pipeline logic, re-usable templates, parameterization, linting, testability, secure defaults, and gating of pipeline changes. Explain how to enforce these practices across many teams while allowing necessary deviations.
