AWS publishes exactly what the DVA-C02 tests and how much each part is worth. Here it is — every domain, its weight, the topics inside it, and the lessons that cover them.
Writing cloud-native application code, developing AWS Lambda functions, and integrating data stores.
Authentication and authorization for applications, encryption with AWS services, and handling sensitive data in code.
Preparing artifacts, testing in development environments, automating deployment testing, and CI/CD deployments.
Root-cause analysis, instrumenting code for observability, and optimizing applications on AWS.
Reading every note front to back is the slowest way to pass. The exam is weighted, so your revision should be too — the blueprint above tells you exactly where the marks are.
Development with AWS Services carries the most marks on the DVA-C02, so it earns the most of your attention. Work down the blueprint from the heaviest domain to the lightest rather than starting at domain 1 and grinding forward.
Read each lesson once without stopping to memorise — you are building a map, not a memory. On the second pass, read only the "what's tested" and key-takeaway blocks. If a takeaway surprises you, that lesson goes back on the pile.
Cover a lesson's key takeaways and try to say them out loud from the heading alone. Recall you can produce under your own steam is the only recall that survives a timed exam; recognition on a re-read is not the same thing.
Finishing the notes is not the goal — scoring is. Move to DVA-C02 practice questions early, then come back to the exact lessons your wrong answers point at. That loop is worth far more than a third read-through.
