Review a compact AWS Certified DevOps Engineer - Professional (DOP-C02) cheat sheet for CI/CD, infrastructure as code, resilience, monitoring, incident response, event automation, and security before using IT Mastery sample questions.
Use this cheat sheet to separate the major DOP-C02 decision areas before trying the sample questions. The current DOP-C02 page includes original sample questions and exam guidance while full IT Mastery practice is being prioritized.
| Item | Review cue |
|---|---|
| Exam route | AWS Certified DevOps Engineer - Professional |
| Exam code | DOP-C02 |
| Items | 75 total, including scored and unscored items |
| Current page status | Sample questions available |
| Best use | Practice safe delivery, repeatable infrastructure, resilient operations, monitoring, event response, and security automation |
| Domain | Weight | What to know | Common trap |
|---|---|---|---|
| SDLC Automation | 22% | pipelines, approvals, test gates, rollback, release safety | replacing automation with manual checklist steps |
| Configuration Management and IaC | 17% | CloudFormation, StackSets, drift, configuration baselines | fixing resources in the console and leaving drift unmanaged |
| Resilient Cloud Solutions | 15% | failover, backup, scaling, health checks, recovery targets | adding complexity without improving recovery behavior |
| Monitoring and Logging | 15% | metrics, logs, alarms, tracing, dashboards, observability | alerting on noisy symptoms instead of actionable signals |
| Incident and Event Response | 14% | EventBridge, Config, Systems Manager, remediation workflows | detecting issues without a safe remediation path |
| Security and Compliance | 17% | least privilege, patching, policy enforcement, audit, encryption | giving automation broad permissions for convenience |
| Distinction | Exam reflex |
|---|---|
| Blue/green vs in-place deployment | Blue/green reduces cutover risk. In-place can be simpler but has less isolation. |
| Drift detection vs change set | Drift detects actual state differences. Change sets preview planned updates. |
| Alarm vs event rule | Alarms react to metric thresholds. Event rules respond to events. |
| Manual remediation vs Systems Manager Automation | Automation is safer for repeatable response when scoped and tested. |
| StackSet vs single stack | StackSets manage multi-account or multi-Region rollout. |
For each miss, label the failure as release safety, infrastructure state, resilience, observability, event response, or security automation. If several misses come from one area, drill SOA-C03 operations or SAA-C03 architecture pages while DOP-C02 coverage is still expanding.
