Question 2mediummultiple choice
Full question →A developer is building a serverless application using AWS Step Functions. The workflow must execute hundreds of thousands of short-lived tasks per day, each taking less than 30 seconds. The tasks need to run in parallel, and a small number of duplicate executions are acceptable. Which type of Step Functions workflow should the developer choose?
Question 3mediummultiple choice
Full question →A developer has an AWS Lambda function that needs to read objects from an S3 bucket in another account. The Lambda function's execution role includes an IAM policy that allows s3:GetObject on the bucket. The bucket owner has added a bucket policy that grants s3:GetObject to the Lambda execution role. However, the Lambda function receives Access Denied errors. The S3 bucket uses SSE-KMS for encryption. What is the most likely cause?
Question 4hardmultiple choice
Full question →A developer is building a REST API using Amazon API Gateway and AWS Lambda. The API receives a large number of requests with duplicate payloads from the same client within a short time window. To reduce Lambda invocations and improve performance, the developer wants to return the previously computed response for identical requests based on a unique client ID in the header. How can the developer achieve this using API Gateway features?
Question 5mediummultiple choice
Full question →A developer is using AWS CodeDeploy to deploy a new version of an AWS Lambda function. The developer wants to gradually shift traffic from the old version to the new version in 10-minute increments. Which deployment configuration should the developer use?
Question 6mediummultiple choice
Full question →A developer is using AWS CodeDeploy to deploy an application to an Amazon ECS service with the Fargate launch type. The deployment uses a blue/green strategy. After the new task set is created and passes the initial health checks, the traffic is shifted to the new task set. However, the new task set is immediately replaced by the old one after a few minutes, causing a rollback. What is the most likely reason?

- ▸Answering from memory before reading the full scenario.
- ▸Missing a constraint such as cost, availability, security, scope or command context.
- ▸Choosing a broad answer when the question asks for the most specific fix.
- ▸Ignoring why the wrong options are tempting.

Frequently asked questions
- What does the DVA-C02 exam test about Scenario?
- Scenario questions test whether you can apply the concept in context, not just recognise a definition.
- How should I use these practice questions?
- Select your answer before revealing the explanation. Then read why each option is right or wrong — this active recall approach builds retention far faster than re-reading notes.
- Can I practise just Scenario questions in a focused session?
- Yes — the session launcher on this page draws every question from the Scenario domain. Use a 10-question session first to gauge your baseline, then move to 20 or 30 once the weak spots are clear.
- Where can I practise other DVA-C02 topics?
- Use the topic links above to move to related areas, or go back to the DVA-C02 question bank to see all topics.
- Are these real exam questions or dumps?
- These are original practice questions written to test the same concepts the DVA-C02 exam covers. They are not copied from any real exam or dump site.
