How does monitoring influence rollback decisions?

• A. Rollbacks are planned regardless of monitoring.
• B. Monitoring has no impact on rollbacks.
• C. Rollbacks should be performed only after a manual audit.
• D. Detects anomalies and performance issues to guide when to rollback.

Answer: (D)

Monitoring provides the real-time feedback you need to decide when a deployment should be reverted. It tracks health signals like error rates, latency, throughput, and resource usage, and checks them against expected baselines or SLOs. When these signals indicate degradation or anomalies, you use that information to guide a rollback to a stable version. This makes the rollback decision data-driven and timely, helping minimize user impact and MTTR. If you roll back regardless of monitoring signals, you might undo good changes or miss problems that later become clear. If monitoring didn’t influence decisions, you wouldn’t have a responsive mechanism to detect issues in production. Relying only on manual audits delays action and increases risk, whereas monitoring enables quick, informed responses even before an official audit completes.
