AWS CloudOps Engineer – Associate (SOA-C03)

SOA-C03 65 items · 130 min Pass 720/1000 $150 Associate

The operator’s exam. Where Solutions Architect asks what you would design, this one asks what you would do at 3 a.m. with an alarm firing. It validates deploying, managing and operating workloads on AWS: monitoring and remediation, reliability and business continuity, deployment automation, security controls, and networking operations — through the console, the CLI and infrastructure as code.

The blueprint

#	Domain	Weight	Where it is taught here
1	Monitoring, Logging, Analysis, Remediation, and Performance Optimization	22%	Monitoring & observability
2	Reliability and Business Continuity	22%	Availability, scaling & networking
3	Deployment, Provisioning, and Automation	22%	Storage, deployment & provisioning
4	Security and Compliance	16%	Governance & automation
5	Networking and Content Delivery	18%	Availability, scaling & networking

Three domains tied at 22% and nothing below 16% — the flattest associate blueprint AWS publishes. There is no domain you can trade away, and no single topic worth more than a fifth of the paper. Study breadth, then depth.

Cost and performance optimisation is no longer its own domain in SOA-C03, but cost work has not disappeared: it moved inside the monitoring and optimisation domain, which is why the cost management page stays in this course.

Exam mechanics

• 65 items, 130 minutes. 50 scored, 15 unscored pretest items mixed in unmarked.
• Scaled 100–1,000, pass at 720, compensatory across domains.
• Multiple choice and multiple response only — no exam labs in this version.
• Unanswered items score as incorrect and there is no guessing penalty.
• Expect console- and CLI-flavoured stems: specific alarm states, specific error text, specific metric names.

The five note pages

#	Page	Study points	Covers
1	Monitoring & observability	12	CloudWatch metrics and custom metrics, alarms, Logs and Logs Insights, dashboards, anomaly detection, composite alarms
2	Availability, scaling & networking	8	Auto Scaling policies and lifecycle hooks, load balancing, multi-AZ patterns, VPC networking and security controls
3	Storage, deployment & provisioning	17	Storage and data management, deployment strategies, Lambda deployment configurations, advanced CloudFormation, Service Catalog
4	Cost management	7	Budgets and budget actions, Cost Explorer, Cost and Usage Reports, allocation tags
5	Governance & automation	13	AWS Config rules and remediation, advanced Systems Manager, Amazon Inspector, automation and governance patterns

57 study points in total, weighted toward the deployment and governance material that the new blueprint pushed up.

The operator instincts the exam rewards

Situation	What the exam wants
A metric you need is missing	Memory, disk and swap on EC2 are not default metrics — install the CloudWatch Agent
An alarm reads INSUFFICIENT_DATA	Not a failure: no data points have arrived in the evaluation period yet
A fix has to happen without a human	Config rule detects, SSM Automation remediates — detection and remediation are two separate pieces
Instances need patching at scale	Systems Manager Patch Manager with patch groups by tag, not a login loop
Shell access must be auditable	Session Manager — no inbound ports, full session logging to CloudWatch Logs and S3
An AMI must be rolled out to a running fleet	ASG Instance Refresh with a minimum healthy percentage, not manual replacement
Someone changed a stack by hand	CloudFormation drift detection, then bring the change back into the template
Spend must be capped, not just watched	Budgets with budget actions, not a Cost Explorer report nobody reads
A deployment must be reversible	Blue/green or canary with automatic rollback on alarm
