DVA-C02 FAQ — Format, Depth, and Study Strategy

VPC: Virtual Private Cloud, the AWS network boundary for subnets, routes, and attached security controls.

KMS: Key Management Service for controlling encryption keys and how applications may use them.

DLQ: Dead-letter queue, where failed messages or events can be isolated for later review and replay.

What is the exam format?

DVA-C02 is a 65-question exam with a 130-minute time limit. Question styles are multiple-choice and multiple-response (no hands-on labs).

What score do I need to pass?

The published minimum passing score is 720 on a 100–1000 scaled score.

Do I need deep AWS networking knowledge?

Not typically. You do need practical awareness of VPC basics, endpoints, and secure connectivity patterns, but DVA-C02 is primarily about building and operating applications with AWS services.

What should I memorize?

• The “best-fit” use cases for Lambda, API Gateway, DynamoDB, S3, SNS/SQS/EventBridge, Step Functions.
• Core security primitives: IAM roles/policies, KMS, Secrets Manager/SSM, basic auth patterns.
• Common failure modes: throttling, timeouts, retries, DLQs, permissions, cold starts.

What’s the most efficient way to study?

1. Read the section overview and internalize domain weights.
2. Use Resources to work from the official exam guide and core service docs.
3. Keep the Cheat Sheet open while practicing eventing, security, and troubleshooting patterns.
4. Finish with timed mixed sets only after you can explain retries, permissions, and async behavior clearly.

How does DVA-C02 compare to SAA-C03?

SAA-C03 is more architecture-heavy across many services. DVA-C02 is more developer-centric: SDK usage, event-driven patterns, deployment automation, and troubleshooting with logs/metrics/traces.
