Episode 12 — Run Change and Configuration Management Without Chaos
Change and configuration management prevent outages and security regressions, and the exam expects you to know their purpose and artifacts. We distinguish configuration baselines from desired state, explain how inventory and versioning tie to risk, and show how approvals, impact analysis, and back-out plans reduce unintended consequences. You’ll see how emergency changes differ from standard and normal changes, why segregation of duties matters, and how evidence—tickets, signatures, timestamps, and diffs—proves control operation. The goal is to reason from policy to practice so you can select the next best step when a scenario involves a risky modification to systems or networks.
We emphasize pragmatic execution patterns. Examples include pre-deployment testing using representative data, phased rollouts with hold points, and configuration drift detection through automated reconciliation. We explore maintenance windows coordinated with business calendars, peer reviews that catch security regressions, and artifact bundles that pair the change request with test results, monitoring thresholds, and rollback procedures. Troubleshooting sections cover failed deployments, conflicting dependencies, and audit findings where “as-built” configurations do not match documentation. You’ll learn to connect change outcomes to monitoring signals—error rates, latency, alert volumes—and to trigger post-implementation reviews that capture lessons and adjust baselines, turning a paperwork process into a reliability engine.
