AWS Certified Developer - Associate (DVA-C02) Practice Test

This certification is designed for software developers and cloud engineers who spend at least a portion of their role building and maintaining applications on AWS. Relevant job titles include Cloud Developer, Backend Developer, Full-Stack Developer, DevOps Engineer, and Solutions Developer. Candidates typically have one or more years of hands-on experience writing application code using AWS services, familiarity with at least one high-level programming language (such as Python, Java, JavaScript, or Go), and practical knowledge of cloud-native development patterns.

Developers who are new to cloud but hold strong general programming backgrounds will also find this exam accessible, though AWS recommends that individuals with no prior IT experience first earn the AWS Certified Cloud Practitioner to build foundational knowledge before attempting this associate-level exam.

There are no formal prerequisites required to register for the DVA-C02 exam. However, AWS recommends that candidates have one or more years of practical experience developing and maintaining applications using AWS services before sitting the exam. Candidates should be comfortable with at least one high-level programming language and have working knowledge of AWS core services such as IAM, S3, DynamoDB, Lambda, API Gateway, SQS, and SNS.

Familiarity with CI/CD concepts and hands-on experience with AWS developer tools (CodeCommit, CodeBuild, CodeDeploy, CodePipeline) is also strongly advised. Candidates should understand RESTful API design, serverless architectures, and basic cloud security principles including authentication via Amazon Cognito and secrets management via AWS Secrets Manager and AWS Systems Manager Parameter Store.

The DVA-C02 exam consists of 65 total questions: 50 scored questions and 15 unscored pretest questions that do not affect the final score (unscored questions are not identified during the exam). Question types are either multiple choice (one correct answer from four options) or multiple response (two or more correct answers from five or more options). The time limit is 130 minutes, and the exam is proctored via Pearson VUE either at an authorized testing center or through an online proctored session. The exam is available in English, Japanese, Korean, Portuguese (Brazil), Simplified Chinese, and Spanish (Latin America).

Scores are reported on a scaled score of 100–1,000, with a minimum passing score of 720. Unanswered questions are scored as incorrect; there is no penalty for guessing. The exam fee is $150 USD, and AWS provides certified holders with a 50% discount voucher for their next certification exam.

• 1.Domain 1 – Development with AWS Services (32%): Writing and optimizing application code hosted on AWS; developing and deploying AWS Lambda functions including event source mappings, layers, and environment variables; using AWS data stores in application development (DynamoDB, ElastiCache, RDS, S3, Amazon Kinesis); integrating applications using Amazon API Gateway, SQS, SNS, EventBridge, and Step Functions; applying event-driven architecture patterns and resilience patterns such as retry logic and exponential backoff.
• 2.Domain 2 – Security (26%): Implementing authentication and authorization using Amazon Cognito user pools and identity pools; managing API access with IAM policies, resource-based policies, and Lambda authorizers; encrypting data at rest and in transit using AWS KMS and ACM; handling sensitive application credentials securely using AWS Secrets Manager and SSM Parameter Store; applying the principle of least privilege to Lambda execution roles and application IAM roles.
• 3.Domain 3 – Deployment (24%): Preparing and packaging application artifacts for deployment to AWS (ZIP packages, container images, SAM templates, CloudFormation); configuring and using AWS CodeBuild, CodeDeploy, and CodePipeline for CI/CD workflows; deploying serverless applications using AWS SAM and the AWS CDK; using deployment strategies including canary, linear, and all-at-once via CodeDeploy; testing applications in development environments using AWS services and local emulation tools.
• 4.Domain 4 – Troubleshooting and Optimization (18%): Using Amazon CloudWatch Logs, CloudWatch Metrics, and AWS X-Ray to instrument and trace applications; performing root cause analysis on application errors including Lambda timeouts, throttling, and cold starts; optimizing Lambda performance through memory allocation, provisioned concurrency, and code profiling; using Amazon Q Developer for code suggestions and debugging assistance; optimizing DynamoDB access patterns and S3 performance configurations.

• Start with the official AWS Exam Prep Standard Course on AWS Skill Builder, which follows the four-step exam prep plan and maps directly to DVA-C02 domains. Complete the official practice question set (20 questions) to calibrate your readiness before purchasing the full practice exam.
• Download and study Version 2.1 of the official DVA-C02 Exam Guide from aws.amazon.com. Review the in-scope and out-of-scope task statements carefully — architectural design and VPC networking design are explicitly out of scope, so avoid over-indexing on those areas.
• Build hands-on experience with Lambda, API Gateway, DynamoDB, SQS/SNS, and Cognito. The exam heavily tests code-level integration knowledge — understand how to configure event source mappings, DynamoDB Streams, SQS triggers for Lambda, and how retry behavior works for each invocation type (synchronous vs. asynchronous).
• Focus significant study time on the Security domain (26% weighting). Understand the difference between Cognito user pools and identity pools, when to use AWS Secrets Manager vs. SSM Parameter Store, how KMS envelope encryption works, and how to scope IAM policies for Lambda execution roles.
• Study the AWS CI/CD toolchain (CodeCommit, CodeBuild, CodeDeploy, CodePipeline) end-to-end. Know the deployment configuration options in CodeDeploy (canary, linear, all-at-once), how buildspec.yml is structured in CodeBuild, and how appspec.yml works for Lambda and EC2 deployments.
• Practice with AWS X-Ray to understand how to instrument Lambda functions and trace requests across distributed services. The Troubleshooting domain (18%) tests your ability to identify bottlenecks and errors using CloudWatch Logs Insights, X-Ray service maps, and CloudWatch Metrics.
• Review the December 2024 exam updates if using older study materials. Version 2.1 added Amazon Q Developer usage, EventBridge event patterns, and resilience patterns (circuit breakers, exponential backoff) — topics not covered in pre-2024 resources.

The AWS Certified Developer – Associate is one of the highest-compensating associate-level cloud certifications available. AWS-certified developers in the United States report average salaries of approximately $130,000–$133,000 per year, with senior roles exceeding $150,000. According to industry salary surveys, AWS-certified IT professionals earn on average 27.5% more than non-certified counterparts, and 19% of certification holders report a direct salary increase following certification. The credential is recognized globally and is frequently listed as a required or preferred qualification in cloud developer job postings across financial services, healthcare, technology, and e-commerce sectors.

Beyond compensation, 63% of certified AWS professionals report receiving or expecting a promotion after certification, and 41% report increased workplace engagement. The DVA-C02 serves as a natural step toward higher-level credentials including the AWS Certified DevOps Engineer – Professional and AWS Certified Solutions Architect – Professional. Compared to vendor-neutral developer certifications, the AWS Developer Associate carries stronger market specificity, particularly for organizations running workloads on AWS — which represents the majority of enterprise cloud deployments.
