After a configuration deployment, over 300 Instana alerts fire within 60 seconds, flooding on-call notification channels. The individual alerts are technically valid but are expected consequences of the deployment. What is the most appropriate Instana feature to prevent this situation during future planned deployments?

Instana maintenance windows are designed specifically for planned change periods such as deployments, where the system may temporarily enter alert conditions as a normal consequence of the change. Activating a maintenance window suppresses alert notifications for the covered entities during the defined period without permanently modifying alert thresholds or sensitivity. This prevents alert fatigue and unnecessary escalations during expected disruption periods while preserving full alerting outside the window. The correct answer is 'Activate a maintenance window in Instana before each planned deployment to suppress expected alerts during the intentional change period'. The incorrect options — 'Increase all alert evaluation intervals to 60 minutes so fewer alert checks occur during deployments', 'Delete all alert policies before each deployment and recreate them once the system stabilizes', 'Configure the Instana backend to batch all alerts into a single daily digest to reduce notification volume' — are wrong because they do not align with IBM Instana's architecture or recommended practices for this scenario. Understanding this concept is essential for the Domain 6: Troubleshooting domain of the IBM Instana Observability certification.
