Topics include Azure Pipelines, GitHub Actions, YAML pipelines, hosted and self-hosted agents, triggers, multi-stage pipelines, dependencies, templates, variable groups, deployment approvals, automated testing, quality gates, artifacts, caching, and Infrastructure as Code.Deployment strategies include blue-green deployments, canary releases, progressive exposure, feature flags, deployment slots, hotfix workflows, database migrations, rollback planning, and resilient deployments.Security and compliance topics cover Azure Key Vault, pipeline secrets, workload identities, service connections, secret scanning, dependency scanning, static analysis, compliance gates, artifact integrity, and software supply-chain security.The course also reviews monitoring and feedback practices using Application Insights, Azure Monitor, distributed tracing, alerts, SLIs, SLOs, telemetry, and continuous improvement feedback loops.Every question includes explanations for the correct answer and each incorrect option. These explanations help you understand why a particular DevOps practice or Microsoft service is appropriate and how similar alternatives differ.By completing all six practice exams, you can identify knowledge gaps, strengthen real-world DevOps decision-making, improve CI/CD and DevSecOps skills, and build confidence through 600 professional practice questions.This course is an independent exam-preparation resource and is not affiliated with, sponsored by, or endorsed by Microsoft.
