Q.) In your CI/CD environment, how would you ensure a reliable rollback mechanism if a deployment fails? Please explain your strategy, tools involved, how you detect failures, and how you execute the rollback. Illustrate with real-world examples or deployment patterns.
When asked, answer clearly on these points :
What triggers a rollback?
How is rollback executed (automation, tools)?
How is state consistency ensured, especially for DBs?
How are artifacts managed and versioned?
How do you test and learn from rollback scenarios?
Q.) Your team’s CI/CD pipeline now takes over an hour to complete. As a DevOps engineer, how would you approach optimizing the pipeline? Please describe your process, tools, and strategies to cut build time while maintaining reliability.
Q.) In your CI/CD deployment pipeline, what strategies and tools do you implement to ensure deployments are successful? How do you monitor in real time and log effectively to detect and diagnose deployment failures? Please describe your overall approach and the tools you rely upon.
I'll be posting a series of DevOps related questions covering various skill levels. Feel free to share your insights and expertise. Your contributions will benefit learners at all stages, from those in current roles to those preparing for DevOps interviews.
