If you're still studying for the "AWS SysOps Administrator" exam, I have bad news: that exam doesn't exist anymore.
AWS quietly retired SOA-C02 in September 2025 and replaced it with the AWS Certified CloudOps Engineer Associate (SOA-C03). And no, it's not just a name change. They rewrote the entire exam blueprint.
The biggest change nobody's talking about
The labs are gone. SOA-C02 was famous (infamous?) for its hands-on lab questions where you had to actually configure things in a live AWS console. People spent weeks practicing lab scenarios.
SOA-C03? All multiple choice. No more labs.
But before you celebrate — the questions got harder. Here's why.
What's actually new in SOA-C03
The exam now explicitly covers:
- Containers — ECS, EKS, ECR, Fargate. If you can't troubleshoot a failing ECS task or explain EKS pod networking, you're toast.
- Multi-account architectures — AWS Organizations, SCPs, cross-account IAM roles. This is easily 15-20% of the exam now.
- Modern IaC — CloudFormation is still king, but expect CDK and SAM questions too.
- Multi-Region operations — DynamoDB Global Tables, cross-region replication, Route 53 failover routing.
The domain breakdown that matters
| Domain | Weight |
|---|---|
| Monitoring, Logging & Remediation | 20% |
| Reliability & Business Continuity | 15% |
| Deployment, Provisioning & Automation | 25% |
| Security & Compliance | 20% |
| Networking & Content Delivery | 20% |
Deployment & Automation at 25% is the highest-weighted domain. If you're spending most of your time on CloudWatch dashboards, you're studying wrong.
The $300 mistake most people make
Here's the thing — most people fail SOA-C03 because they're using SOA-C02 study materials. The old Stephane Maarek course? Tutorial Dojo's old practice exams? They don't cover containers or multi-account architectures at all.
You need 2026-updated materials. Period.
For free practice questions that are already updated for the SOA-C03 blueprint, I've been using ExamCert's CloudOps Engineer practice test. It's $4.99 for lifetime access to the full question bank with a pass-or-refund guarantee. Compare that to dropping $300 on the actual exam and failing because your practice tests were outdated.
My recommended study plan
- Week 1-2: Stephane Maarek's updated SOA-C03 course on Udemy (wait for a sale)
- Week 3-4: Hands-on labs in your own AWS account — focus on ECS deployments, CloudFormation stacks, and Organizations setup
- Week 5-6: Practice exams from at least two different sources
- Week 7: Review weak areas, drill scenario questions
- Week 8: Take the exam
8 weeks. That's all you need if you're already SAA-C03 certified. If you're coming in fresh, add 2-3 more weeks for AWS fundamentals.
Stop using outdated materials
The SOA-C03 is a fundamentally different exam from SOA-C02. The name change wasn't cosmetic — it reflects how AWS operations actually work in 2026: containers, multi-account, automation-first.
If your study guide doesn't mention ECS, EKS, or AWS Organizations, throw it away and start over.
