Official domains and our selected practice

Weights describe the exam’s scored content, not how much of a domain this site covers. Every domain below has gaps. Use the linked official guide to plan the rest of your study.

Development with AWS Services · 32%

Available here: Explore supported local integrations, key-based access and duplicate-safe processing concepts.

Still needed beyond this path: Real SDK code, complete Lambda event-source behavior, Step Functions and the full developer-service portfolio are absent.

Security · 26%

Available here: Identify a workload role and the narrow action/resource scope for a request.

Still needed beyond this path: Real credential issuance, application authentication, encryption and secret rotation need additional hands-on study; simulated secrets are not cryptography.

Deployment · 24%

Available here: Compare declarative infrastructure and supported local function configuration workflows.

Still needed beyond this path: There is no running CI/CD pipeline, full SAM/CDK deployment, application build or live canary traffic test.

Troubleshooting and Optimization · 18%

Available here: Use synthetic logs and failures to isolate a request, permission or key mismatch.

Still needed beyond this path: Real distributed tracing, profiling, runtime debugging and production optimization require real applications.

Build the concept before memorizing an answer

Read the explanation, predict a changed scenario, run an experiment and explain the outcome. Return to a topic after a gap. These local exercises supplement study; they do not replace experience using the real services.
