About This Domain
Domain 1 — Monitoring, Logging, Analysis, Remediation, and Performance Optimization — accounts for 22% of the SOA-C03 certification exam. This domain evaluates your understanding of cloudwatch metrics, alarms, dashboards, logs, metric filters, and logs insights, cloudtrail trails, organization-wide auditing, log integrity, and long-term retention, operational analysis with traces, service maps, anomaly detection, and health signals, and related concepts. Domain 1 validates operational visibility, log analysis, incident response, remediation automation, and performance optimization across AWS workloads. To pass this section you need practical knowledge of how these services and patterns work together in real-world architectures.
What You'll Be Tested On
- CloudWatch metrics, alarms, dashboards, logs, metric filters, and Logs Insights
- CloudTrail trails, organization-wide auditing, log integrity, and long-term retention
- Operational analysis with traces, service maps, anomaly detection, and health signals
- Automated remediation using Systems Manager, EventBridge, AWS Config, and Lambda
- Performance tuning with right-sizing, Compute Optimizer, storage metrics, and scaling signals

Study Strategy for Domain 1
While 22% might seem like a smaller portion of the exam, every point counts toward the passing score. Focus on understanding core concepts and common exam scenarios for this domain. Don't neglect it — even a few missed questions here can make the difference between pass and fail.
Exam Tips for Domain 1
Expect scenarios that ask which telemetry source proves what happened: CloudTrail for API activity, CloudWatch for resource/application metrics, and X-Ray for traces.
For automatic remediation, pair a detector with an action: AWS Config or EventBridge can trigger Systems Manager Automation or Lambda.
Composite alarms reduce noise when multiple conditions must be true before paging an operator.
Performance optimization questions often hinge on the right metric: CPU, memory via the CloudWatch agent, IOPS, throughput, latency, or queue depth.
