   A team is deploying a new version of a critical service. They want to release it to a small percentage of users first to monitor its performance and error rates before rolling it out to everyone. They also want to be able to automatically stop the rollout if the error rate exceeds a threshold. Which deployment strategy and feedback mechanism should they use?

   • ARolling deployment with no automated monitoring
   • BRecreate deployment with manual verification
   • CCanary deployment with automated monitoring and rollback based on error rate thresholds
   • DBlue-green deployment with manual rollback after a fixed time period

   An organization has separate development, staging, and production environments. They are experiencing issues where an application behaves differently in staging than in production, leading to unexpected failures after deployment. The team wants to ensure that the environments are as similar as possible. Which approach is the most effective way to achieve this consistency?

   • AUse a configuration management tool to define the infrastructure and application configuration as code, and apply the same definitions to all environments
   • BManually configure each environment by following a detailed runbook
   • CUse a containerization platform to package the application and its dependencies, but keep the host operating systems different
   • DCopy the production environment's configuration files to staging and development

   A development team is setting up a CI/CD pipeline for a critical financial application. The pipeline must automatically run unit and integration tests on every commit, but deployment to the production environment requires a manual approval from the release manager. Additionally, the pipeline must scan dependencies for known vulnerabilities before the deployment step. Which pipeline design correctly implements these requirements?

   • AA pipeline that runs the build and tests, then automatically deploys to production, with the security scan running after deployment
   • BA pipeline with a manual approval gate before the build stage, then automated tests and deployment
   • CA pipeline with stages for build, test, and security scan, followed by a manual approval gate before the deploy stage
   • DA pipeline that only runs the security scan and then deploys to production without any tests
