Review a compact AWS Certified CloudOps Engineer Associate (SOA-C03) cheat sheet for monitoring, remediation, reliability, automation, security, networking, and operations decisions before using IT Mastery practice.
Use this cheat sheet to keep SOA-C03 operations decisions organized before practice. The exam rewards the answer that finds the right signal, remediates safely, automates repeatable work, and preserves reliability.
| Item | Review cue |
|---|---|
| Exam route | AWS Certified CloudOps Engineer Associate, formerly SysOps Administrator Associate |
| Exam code | SOA-C03 |
| Items | 65 total |
| Time | 130 minutes |
| Practice option | Live IT Mastery practice available |
| Best use | Practice monitoring, automation, remediation, security, networking, and reliability operations |
| Domain | Weight | What to know | Common trap |
|---|---|---|---|
| Monitoring, logging, analysis, remediation, and performance optimization | 22% | CloudWatch, logs, alarms, metrics, traces, root-cause signals | acting before finding the first useful signal |
| Reliability and business continuity | 22% | backups, restore, failover, Multi-AZ, recovery objectives, testing | assuming backups are useful without restore validation |
| Deployment, provisioning, and automation | 22% | infrastructure as code, Systems Manager, automation, deployment safety | using manual console fixes for repeatable tasks |
| Security and compliance | 16% | IAM, patching, encryption, audit, access control, configuration | over-permissioning operations roles for convenience |
| Networking and content delivery | 18% | VPC routing, DNS, load balancing, connectivity, CDN, endpoints | troubleshooting the application before checking routing and security groups |
| Distinction | Exam reflex |
|---|---|
| Metric vs log | Metrics show numeric behavior. Logs show event detail. Use both when diagnosing. |
| Alarm vs dashboard | Alarms trigger action. Dashboards support visibility. |
| Backup vs disaster recovery | Backups preserve data. Disaster recovery needs tested recovery workflow and target objectives. |
| Systems Manager vs manual SSH | Systems Manager supports controlled fleet operations without unmanaged server access. |
| Security group vs network ACL | Security groups are stateful. Network ACLs are stateless. |
| Scaling policy vs scheduled scaling | Policies react to metrics. Scheduled scaling handles predictable demand. |
For each missed SOA-C03 item, label the operations layer: signal, remediation, reliability, automation, security, or networking. If misses cluster in troubleshooting, practice reading the evidence before looking at the answer choices.
