Domain weightings

How much of the exam each domain covers. Spend your study time in proportion — the heavier the domain, the more questions you'll see.

Key terms

CodePipeline

AWS CodePipeline is a fully managed continuous-delivery service that models and automates release pipelines with stages and actions. DOP-C02 relies on it as the backbone of SDLC automation across build, test, and deploy.

CodeBuild

AWS CodeBuild is a fully managed build service that compiles source, runs tests, and produces deployable artifacts. DOP-C02 covers it as the build stage within CI/CD pipelines.

CodeDeploy

AWS CodeDeploy is a deployment service that automates releases to EC2, ECS, and Lambda with strategies like blue/green and canary. DOP-C02 covers it for controlled, automated deployments and rollbacks.

Blue/Green Deployment

A blue/green deployment runs a new version alongside the old and shifts traffic once the new version is verified, enabling fast rollback. DOP-C02 covers it and canary/rolling strategies across compute services.

CloudFormation

AWS CloudFormation is an infrastructure-as-code service that provisions AWS resources from declarative templates, with stacks, stack sets, and drift detection. DOP-C02 covers it as the core IaC tool for repeatable environments.

AWS CDK

The AWS Cloud Development Kit (CDK) is a framework for defining infrastructure as code using general-purpose programming languages that synthesize to CloudFormation. DOP-C02 covers it alongside CloudFormation for IaC.

Systems Manager

AWS Systems Manager is a service for operating and automating management of AWS resources, including Automation runbooks, Run Command, Patch Manager, and Parameter Store. DOP-C02 covers it for configuration management and auto-remediation.

EventBridge

Amazon EventBridge is an event bus that routes events from AWS services and applications to targets such as Lambda and Systems Manager. DOP-C02 covers it for event-driven operations and automated incident response.

CloudWatch

Amazon CloudWatch is the monitoring and observability service that collects metrics, logs, alarms, and dashboards. DOP-C02 covers it, with Logs Insights and metric filters, for the monitoring and logging domain.

X-Ray

AWS X-Ray is a distributed tracing service that records how requests flow across services to help find performance bottlenecks and errors. DOP-C02 covers it for observability of distributed applications.

AWS Config

AWS Config is a service that records resource configurations and evaluates them against rules for compliance. DOP-C02 covers it, with conformance packs, for compliance-as-code and drift detection.

Security Hub

AWS Security Hub is a service that aggregates and prioritizes security findings across AWS accounts against standards like CIS and AWS Foundational Security Best Practices. DOP-C02 covers it for automating security and compliance.

GuardDuty

Amazon GuardDuty is a threat-detection service that continuously analyzes AWS logs for malicious or anomalous activity. DOP-C02 covers it as a source of findings for automated incident and event response.
