DVA-C02 Study Guide + Practice
Short notes + common traps + quick practice. Then validate with the mini test.
Quick answers
- Read notes → do 10 questions → review mistakes immediately.
- Write 1 rule per mistake (symptom → cause → fix / concept → example).
- Repeat within 24–48 hours to lock it in.
- When accuracy is stable, switch to timed simulator practice.
This DVA-C02 guide covers serverless patterns you see often: when to use Lambda, how EventBridge routes events, and what reliability controls exist.
Fast mental model: Lambda runs code on events; EventBridge routes events between services/apps; reliability comes from retries and dead-letter patterns.
Do the mini quiz to validate. Then continue in PrepMaster for offline packs, timed practice, and explanations.

Frequently Asked Questions
What’s the simplest EventBridge value proposition?
Decoupling: route events to targets without tightly coupling services together.
Why do retries and DLQs matter in serverless questions?
Because reliability depends on what happens when processing fails.
