The AWS Certified Developer – Associate certification focuses on building, securing, testing, releasing, and troubleshooting applications on AWS. DVA-C03 includes using AI tools during development and integrating managed AI services.
Build your preparation around a small application you can improve throughout your review. Add authentication, persistence, asynchronous processing, deployment automation, and monitoring. Keep a record of failures and explain how you resolved each one.
The AWS Certified Developer – Associate Certification Exam Overview
AWS recommends at least one year of practical AWS application development experience. Familiarity with a programming language, SDKs, the AWS CLI, and application lifecycle practices provides a useful foundation.
The official AWS Exam Guide, AWS Documentation, and AWS Whitepapers will be your primary study materials for this exam. Experience in building systems will also be helpful since the exam constitutes of multiple scenario-type questions. You can learn more details on your exam through the official AWS Certified Developer – Associate DVA-C03 Exam Guide here. Do a quick read on it to be aware of how to prepare and what to expect on the exam itself.
Difference between the DVA-C02 and DVA-C03 AWS Certified Developer Associate Exam Versions
The updated exam adds AI-assisted coding, test generation, troubleshooting, and optimization. It also expands container deployment coverage and introduces a dedicated AI security task covering privacy, input/output protection, agent permissions, and sensitive logs.
Some topics move between domains. Lambda performance tuning moves to Troubleshooting and Optimization, while SAM unit testing moves to Testing and Deployment. These changes reorganize existing skills as well as introducing new material.

Common Exam Scenarios for the DVA-C03 Exam
Domain 1: Development with AWS Services
| Scenario | Approach to Evaluate |
|---|---|
| A Lambda function must process events from an SQS queue. | Configure an event source mapping and review retries, error handling, and failure processing. |
| An API must validate incoming requests before invoking its backend. | Configure API Gateway request validation and the required request or response transformations. |
| An application needs to retrieve DynamoDB items efficiently. | Review partition keys, indexes, Query versus Scan, and the required read consistency. |
| A function must access a private database. | Configure Lambda VPC access and verify connectivity and application permissions. |
| A developer uses AI to generate application code. | Review generated code, validate service integrations, and test correctness and security before use. |
Domain 2: Security
| Scenario | Approach to Evaluate |
|---|---|
| An application needs temporary access to resources in another account. | Use AWS STS role assumption. Check the role trust policy and the permissions required by the caller and assumed role. |
| Users need temporary access to a private S3 object. | Generate an S3 presigned URL with an appropriate expiration and narrowly scoped signing permissions. |
| Database credentials must not be embedded in source code. | Retrieve credentials through an appropriate secret management service and restrict application access. |
| An AI application sends sensitive information to a managed service. | Review service privacy controls, private connectivity, input and output filtering, and sensitive-data protection in logs. |
| An AI agent can execute sensitive actions. | Apply tool-use authorization, isolate sessions, and require human approval where appropriate. |
Domain 3: Testing and Deployment
| Scenario | Approach to Evaluate |
|---|---|
| A Lambda application requires different settings for test and production. | Review environment-specific configuration, Lambda aliases, and API Gateway stages. |
| A containerized application must be released to AWS. | Build and tag the image in ECR, then use the appropriate ECS task definition or EKS manifest for deployment. |
| A release must gradually receive production traffic. | Evaluate a canary deployment and configure validation and rollback for the target service. |
| An application needs repeatable deployment and test validation. | Use appropriate SAM, CDK, or CloudFormation templates and validate application behavior with test events and mocks. |
| AI-generated tests need to be included in a release workflow. | Review their assertions and coverage, run them through the testing workflow, and investigate failures before promotion. |
Domain 4: Troubleshooting and Optimization
| Scenario | Approach to Evaluate |
|---|---|
| An application begins failing after a deployment. | Inspect deployment output and correlate application logs, metrics, and traces to identify the cause. |
| A Lambda function is slow under increasing load. | Measure resource usage and bottlenecks, then evaluate memory, compute, concurrency, and downstream connections. |
| Support teams cannot trace a request across services. | Implement structured logging and tracing, and correlate diagnostic information across application components. |
| Repeated reads create application performance bottlenecks. | Evaluate an appropriate cache, such as ElastiCache, DAX, or CloudFront, based on the workload. |
| An AI tool suggests a fix for a production error. | Validate the suggestion against observed logs and metrics, test the change, and verify the resulting behavior. |

Some Notes Regarding Your DVA-C03 Exam
DVA-C03 preparation should focus on developing, securing, testing, deploying, and troubleshooting AWS applications, including using AI-assisted development tools. Understand how application code interacts with AWS services through APIs, SDKs, and event-driven workflows.
Before comparing answers, identify the application’s requirements, such as response time, message ordering, error handling, access permissions, deployment safety, and operational effort.
Read every option carefully. A service might suit the general use case while its proposed configuration fails a specific requirement. Pay attention to IAM permissions, SDK retry behavior, Lambda invocation types, DynamoDB access patterns, and application configuration.
For multiple-response questions, select the required number of answers. Eliminate choices that violate the requirements, then check whether the remaining options work together as a complete solution.
During your review, practice comparing services and features relevant to application development, including:
-
SQS vs. SNS vs. EventBridge — message queues, publish/subscribe messaging, and event routing.
-
SQS Standard vs. FIFO queues — ordering, duplicate handling, and throughput requirements.
-
Lambda synchronous vs. asynchronous invocations vs. event source mappings — response handling, retries, and failure processing.
-
Lambda versions vs. aliases — immutable code versions and deployment traffic management.
-
DynamoDB Query vs. Scan; GSIs vs. LSIs — efficient data access and index selection.
-
IAM roles vs. resource-based policies — application permissions and access to resources.
-
Amazon Cognito user pools vs. identity pools — user authentication and temporary AWS credentials.
-
Secrets Manager vs. Systems Manager Parameter Store vs. AppConfig — secrets, configuration values, and controlled configuration updates.
-
CodeBuild vs. CodeDeploy vs. CodePipeline — building and testing code, deploying applications, and coordinating delivery workflows.
-
CloudFormation vs. AWS SAM vs. AWS CDK — defining and deploying application infrastructure.
-
CloudWatch vs. X-Ray vs. CloudTrail — application monitoring, distributed tracing, and AWS API activity.
-
Canary vs. linear vs. all-at-once deployments — release speed, traffic shifting, and rollback considerations.
The Tutorials Dojo Comparison of AWS Services contains excellent cheat sheets comparing these seemingly similar services which are crucial to solving the tricky scenario-based questions in the actual exam. By knowing each service’s capabilities and use cases, you can consider these types of questions already half-solved.
Lastly, be on the lookout for “key terms” that will help you realize the answer faster. Words such as millisecond latency, serverless, managed, highly available, most cost-effective, fault-tolerant, mobile, streaming, object storage, archival, polling, push notifications, etc are commonly seen in the exam. Time management is very important when taking AWS certification exams, so be sure to monitor the time you consume for each question.
