Infrastructure and Deployment Troubleshooting Questions

Covers a systematic approach to diagnosing and resolving infrastructure and deployment failures across cloud and on premise environments. Topics include collecting and interpreting logs, metrics, and traces; isolating failures and performing root cause analysis; verifying network connectivity, identity and access management, and resource configuration; debugging containerization and operating system level issues; diagnosing continuous integration and continuous delivery pipeline failures across build, test, and deploy stages; addressing infrastructure as code drift and service limits; applying rollback, canary, and incremental deployment strategies; deciding when to escalate versus handling directly; and conducting incident response and post incident learning to prevent recurrence.
