13. How do you implement rolling updates?
Advanced
Rolling updates through deployment orchestration, version management. Handle traffic routing, health checks. Consider zero-downtime deployment, rollback procedures.
14. How do you handle configuration management?
Moderate
Configuration management through environment files, runtime config. Implement secure storage, access control. Consider configuration versioning, audit trail.
15. How do you handle deployment rollbacks?
Moderate
Rollbacks through version control, deployment history. Implement automated rollback procedures. Consider data consistency, dependency compatibility.
16. What are deployment documentation practices?
Basic
Documentation practices: deployment procedures, configuration guides, troubleshooting steps. Maintain version history, change logs. Consider knowledge transfer, maintenance.
17. How do you configure different environments in Angular?
Moderate
Environments configured through environment.ts files. Create environment-specific files, use fileReplacements in angular.json. Configure variables per environment. Important for different deployment scenarios.

Advanced
Deployment strategies: blue-green deployment, canary releases, rolling updates. Consider zero-downtime deployment, rollback capabilities. Implement proper monitoring, health checks.
21. How do you implement feature flags in deployment?
Moderate
Feature flags through configuration management, runtime toggles. Handle feature enabling/disabling, A/B testing. Consider flag cleanup, documentation.
22. What are deployment testing strategies?
Moderate
Deployment testing through smoke tests, integration tests. Implement automated validation, environment verification. Consider test coverage, failure scenarios.
23. How do you implement continuous integration/deployment (CI/CD)?
Advanced
CI/CD implementation through pipelines (Jenkins, GitLab CI, etc.). Include build, test, deploy stages. Configure environment variables, deployment targets. Consider automated testing, versioning.
