From AWS
About SOA-C03
The successor to SysOps Administrator. It covers running production on AWS: CloudWatch metrics, alarms and automated remediation, backups and recovery, infrastructure as code with CloudFormation and CDK, and keeping networks and accounts compliant.
Who it's for. Operations, SRE and platform engineers who keep AWS workloads healthy day to day.
How to prepare
- Think in detect, notify, remediate: a CloudWatch alarm or EventBridge rule, an SNS topic, then an SSM Automation runbook or a Lambda function.
- Know what CloudWatch can’t see without the agent, such as memory and disk space on EC2.
- CloudFormation behaviour is tested in detail: stack policies, drift detection, change sets, DeletionPolicy and StackSets.
Sample SOA-C03 questions
Try these with the answers on the page, then practise the full bank.
- EC2 instances in a fleet report CPU and network statistics to CloudWatch, but memory and disk utilization are missing. What is the standard way to publish those two metrics? Monitoring, logging and remediation
- A security team wants to deploy one curated collection of AWS Config rules and remediations to many accounts and Regions at once. Which Config feature provides that bundle? Monitoring, logging and remediation
- Compute Optimizer reports that several EC2 instances consistently use under 10 percent CPU and memory. Which recommendation category describes them? Monitoring, logging and remediation
- A gp3 volume reaches its included 3,000 IOPS during nightly batch runs. Which change adds IOPS with the least disruption and lowest cost? Monitoring, logging and remediation
- During a suspected scraping attack, the team wants a real-time ranking of the client IP addresses generating the most 4xx responses on an ALB. Which feature provides that ranking? Monitoring, logging and remediation
- An RDS for MySQL database must survive an Availability Zone failure with automatic failover and no changes to application connection code. Which configuration meets that? Reliability and business continuity
- A Route 53 health check should report unhealthy only when a specific CloudWatch alarm is in the ALARM state. Which health check type should be created? Reliability and business continuity
- A central account must deploy an identical VPC baseline into 50 accounts across 4 Regions, including accounts created later. Which CloudFormation capability fits best? Deployment, provisioning and automation

Questions people ask
Is this SOA-C03 practice exam free?
Yes. All 419 questions, the timed mock exam and the explanations are free, and there's no account to create.
Are these real exam questions?
No. Real exam questions are confidential under the AWS candidate agreement. These are practice questions written to cover the same domains in the same scenario style, each with an explanation of why the answer is right.
How is the SOA-C03 mock exam scored?
Questions are drawn from every domain in proportion to the exam guide, and you get a raw percentage with a breakdown by domain. AWS uses scaled scoring, so treat 75% or more here as a sign you're ready rather than a predicted score.
