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

DVA-C02 weights Development with AWS Services heaviest at 32 percent of scored content, followed by Security at 26 percent, Deployment at 24 percent, and Troubleshooting and Optimization at 18 percent. This practice bank of 536 questions is built to match that split, so you spend proportionally more time on writing and optimizing application code against AWS service APIs than on any single domain.

On test day you face 65 questions in 130 minutes: 50 scored and 15 unscored questions AWS uses to test future content, mixed in without being identified. Scoring is scaled from 100 to 1,000, and you need 720 to pass. AWS explicitly scopes out architecture design, IAM administration, and networking infrastructure from this exam, so expect application-layer questions on AWS SDKs and the CLI, securing application code and data, and debugging deployed applications, not designing distributed systems.

AWS recommends 1 or more years of hands-on experience developing and maintaining applications on AWS, plus proficiency in at least one programming language, though there's no formal prerequisite. The certification is valid for 3 years. Start with the 30 free questions, then work through the full 536-question bank until your accuracy holds steady across all four domains.

The AWS Certified Developer – Associate (DVA-C02) is an intermediate-level certification from Amazon Web Services that validates a candidate's proficiency in developing, testing, deploying, and debugging cloud-based applications on the AWS platform. It demonstrates hands-on competency with core AWS developer services including AWS Lambda, Amazon API Gateway, Amazon DynamoDB, Amazon S3, Amazon SQS, Amazon SNS, AWS CodePipeline, AWS CodeBuild, AWS CodeDeploy, and the AWS SDKs and CLI. The exam was updated in December 2024 (Version 2.1) to include 18 new skills, incorporating topics such as Amazon Q Developer, event-driven architecture patterns with Amazon EventBridge, and resilience patterns like retry logic and circuit breakers.

The certification covers four weighted domains: developing applications with AWS services (32%), implementing security controls (26%), automating deployment workflows (24%), and troubleshooting and optimizing applications (18%). It is recognized globally as a benchmark for cloud developers and is valid for three years, after which holders can recertify by retaking the current exam version or by earning the AWS Certified DevOps Engineer – Professional credential.

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.

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.
