SOA-C03 Exam Guide: CloudOps Engineer — Format, Domains, and How to Prepare
The AWS Certified CloudOps Engineer – Associate (SOA-C03) is the renamed and updated successor to the SysOps Administrator – Associate (SOA-C02, retired September 29, 2025). It validates operating production workloads on AWS — monitoring, reliability, deployment, security, and networking.
Key change from SOA-C02: five domains instead of six (Cost and Performance Optimization merged into Domain 1), plus new scope for containers (ECR/ECS/EKS), CDK, and multi-account/multi-Region operations.
Exam format at a glance
- 65 questions — multiple choice and multiple response
- 130 minutes — about 2 minutes per question
- $150 USD
- Passing score: 720 on a scaled range of 100–1000
- Pearson VUE testing center or online proctored exam
The five domains
- Domain 1: Monitoring, Logging, Analysis, Remediation, and Performance Optimization — 22%
- Domain 2: Reliability and Business Continuity — 22% (up from 16% in SOA-C02)
- Domain 3: Deployment, Provisioning, and Automation — 22% (up from 18%)
- Domain 4: Security and Compliance — 16%
- Domain 5: Networking and Content Delivery — 18%
What the exam actually tests
SOA-C03 is operations-first: CloudWatch metrics/alarms/logs (including agent-collected OS metrics like memory), Config-based compliance and EventBridge/SSM remediation, CloudFormation operations (drift, change sets), Systems Manager (Patch Manager, Session Manager, Automation), backup/DR implementation, and VPC/Route 53/ALB troubleshooting.
New-for-C03 scope includes container operations and CloudFormation/CDK provisioning — if you prepared on SOA-C02 materials, top up with ECS/EKS operational basics and CDK stack management.
A realistic prep plan
Budget 4–8 weeks. The exam rewards operational instinct — know not just what CloudWatch does, but which alarm/metric/log combination detects a given failure mode.
- Weeks 1–2: Domains 1–2 — CloudWatch end-to-end, EventBridge remediation, AWS Backup, Auto Scaling health checks
- Week 3: Domain 3 — CloudFormation drift/change sets, Systems Manager, patching, image pipelines, CDK basics
- Week 4: Domain 4 — IAM operations, Config rules, Security Hub, compliance enforcement
- Week 5: Domain 5 — VPC connectivity, Route 53, ALB health checks, CloudFront
- Final week: timed practice + hands-on console drills on weak services
