- "DVA-C02" is AWS's exam code: DVA (Developer Associate), C02 (second commercial version).
- The exam has 65 questions (50 scored, 15 unscored) in 130 minutes, passing score 720/1000.
- Development with AWS Services is the largest domain at 32%, centered on Lambda, DynamoDB, and API Gateway.
- No prerequisites are enforced, but AWS recommends roughly 1 year of hands-on development experience.
What Does "DVA-C02" Actually Mean?
"DVA-C02" is not a random string - it's Amazon Web Services, Inc.'s internal exam code, and each segment carries a specific meaning. "DVA" stands for Developer Associate, identifying the certification track within AWS's broader certification family (which also includes Solutions Architect, SysOps Administrator, and specialty tracks). "C02" indicates this is the second commercial version of the exam blueprint, replacing the earlier DVA-C01 version that AWS has since retired. Understanding this naming convention matters because AWS updates exam codes whenever it substantially revises content, and searching for outdated code numbers can lead candidates to stale study material.
If you're just starting to explore this credential, our companion piece on what DVA-C02 is walks through the certification's purpose in more depth, while what DVA-C02 stands for digs further into the naming history. This article focuses specifically on unpacking the meaning behind the code and translating that into what you actually need to know to pass.
Exam Mechanics Behind the Name
Knowing what the code means is only useful if you also understand the mechanics of the exam it labels. The DVA-C02 exam is delivered through Pearson VUE, either at a physical test center or via online proctoring, and costs $150 USD - AWS does not publish a separate member/non-member pricing tier the way some other certification bodies do.
The exam itself consists of 65 questions, but only 50 of those are scored; the remaining 15 are unscored pretest questions AWS uses to evaluate future exam content, including emerging AI-assisted development and AI security topics. You won't know which questions are scored, so every question deserves full attention. Candidates get 130 minutes to complete the exam, and questions come in two formats: multiple choice (one correct answer) and multiple response (select two or more correct answers from a longer list).
Passing requires a scaled score of 720 out of a possible 1000, calculated using compensatory scoring - meaning you don't need to pass each domain individually, just achieve a strong enough combined score across all four. AWS does not publicly disclose pass rates, so treat any specific percentage you see elsewhere with skepticism; for a deeper look at what data actually exists, see our DVA-C02 pass rate analysis.
Key Takeaway
Unanswered questions count as incorrect with no separate guessing penalty - always select an answer before time runs out, even a guess.
What the Four Domains Mean for Your Study Plan
The real substance behind "DVA-C02" lives in its four exam domains. These aren't abstract categories - they map directly to job tasks AWS expects certified developers to perform.
Domain 1: Development with AWS Services (32%)
This is the largest domain by weight, and it centers on writing and running application code that interacts with AWS. Expect deep coverage of serverless and data-store patterns.
- Building and invoking AWS Lambda functions with appropriate triggers
- Designing DynamoDB tables, indexes, and access patterns
- Configuring API Gateway endpoints and integrations
- Using AWS SDKs and CLI for programmatic interaction with services
- Implementing event-driven architectures with queues, topics, and streams
Domain 2: Security (26%)
Security is nearly a third of the exam, reflecting how central IAM, encryption, and credential management are to real-world development on AWS.
- Applying least-privilege IAM policies to application roles
- Managing secrets and credentials securely (avoiding hardcoded keys)
- Implementing authentication and authorization for APIs
- Encrypting data at rest and in transit
Domain 3: Deployment (24%)
This domain tests your familiarity with getting code from a repository into a running AWS environment reliably.
- Packaging applications for deployment (containers, Lambda layers, zip artifacts)
- Building CI/CD pipelines with services like CodePipeline and CodeDeploy
- Using Infrastructure as Code tools such as CloudFormation or SAM
- Managing deployment strategies (blue/green, canary, rolling)
Domain 4: Troubleshooting and Optimization (18%)
The smallest domain by weight but still critical - it tests your ability to diagnose and improve applications already in production.
- Reading CloudWatch logs, metrics, and X-Ray traces to debug issues
- Identifying performance bottlenecks in Lambda, DynamoDB, or API Gateway
- Applying caching strategies to reduce latency and cost
- Root-causing errors in distributed, event-driven systems

Who Earns the DVA-C02 and Why
The "Developer Associate" part of the name signals exactly who this credential targets: software engineers and developers who build and maintain applications on AWS infrastructure, rather than infrastructure architects or systems administrators. There are no formal prerequisites enforced by AWS, but the organization recommends at least 1 year of hands-on experience developing and maintaining applications on AWS, proficiency in at least one high-level programming language, familiarity with the application lifecycle, hands-on experience with the AWS CLI, SDKs, and APIs, exposure to CI/CD practices, and a working understanding of application security concepts.
In practice, this means the exam suits backend developers, full-stack engineers, and cloud-native application builders more than it suits pure DevOps or networking specialists (that audience is better served by the AWS Certified DevOps Engineer - Professional credential, which - notably - can also be used to renew the DVA-C02). If you're curious what kinds of roles list this certification as a requirement or preference, the DVA-C02 jobs overview breaks down common titles and responsibilities, and the DVA-C02 salary guide looks at earnings context for certified developers.
DVA-C02 vs. the Retired DVA-C01
Because AWS periodically refreshes its exam blueprints, it's worth understanding what changed between versions. The current version is DVA-C02, and its English exam guide has expanded to include emerging AI-assisted development and AI security topics - some of which may appear only as unscored pretest questions rather than counting toward your score. This is a meaningful shift from earlier developer exams, which focused almost exclusively on traditional serverless and container-based development patterns.
| Attribute | DVA-C02 (Current) |
|---|---|
| Total Questions | 65 (50 scored, 15 unscored) |
| Exam Duration | 130 minutes |
| Passing Score | 720 / 1000 (scaled, compensatory) |
| Fee | $150 USD |
| Format | Multiple choice & multiple response |
| Validity | 3 years |
| Delivery | Pearson VUE test center or online proctoring |
If you're evaluating whether the exam has gotten harder or easier with this version, our difficulty guide addresses that question directly using what's actually documented about the exam structure, rather than speculation.
Registration, Fee, and Scoring Mechanics
Once you understand what DVA-C02 means conceptually, the practical registration details matter just as much. Exams are scheduled through Pearson VUE, and you can choose between an in-person test center or remote online proctoring depending on your comfort level and local availability. The fee is a flat $150 USD regardless of delivery method.
A few mechanics worth internalizing before exam day:
- Unanswered questions are marked incorrect - there is no penalty distinct from simply not answering, so always submit a guess rather than leaving a blank.
- The 15 unscored questions are mixed in with the 50 scored ones and are not identified, so you must treat every question as if it counts.
- There are no hands-on labs on this exam - it is entirely multiple choice and multiple response, delivered in a testing interface, not a live AWS console.
- Non-native English speakers can request a 30-minute time extension if the exam is not yet available in their preferred language.
- Certification is valid for 3 years, after which you must pass the latest Developer - Associate exam or the AWS Certified DevOps Engineer - Professional exam to renew.
- Active AWS certification holders receive exam benefits, including a 50% discount voucher toward future exams.

And if you're still deciding whether the entire path is worth pursuing, the DVA-C02 certification overview and what DVA-C02 certification is both provide useful framing before you commit to a registration date.
Turning the Meaning Into a Study Plan
Understanding what DVA-C02 means - the domains, the scoring, the audience - should directly shape how you allocate study time. Since Development with AWS Services carries the heaviest weight at 32%, it deserves proportionally more study hours than Troubleshooting and Optimization at 18%, even though both matter for passing under compensatory scoring.
Development with AWS Services (32%)
- Build and deploy Lambda functions with various trigger types
- Practice DynamoDB table design, GSIs, and query patterns
- Configure API Gateway REST and HTTP APIs end-to-end
Security (26%)
- Write and troubleshoot IAM policies for Lambda execution roles
- Practice using Secrets Manager and Parameter Store
- Review encryption options for S3, DynamoDB, and Lambda environment variables
Deployment (24%)
- Build a sample CI/CD pipeline with CodePipeline and CodeDeploy
- Practice SAM or CloudFormation templates for serverless stacks
- Compare blue/green vs. canary deployment configurations
Troubleshooting and Optimization (18%) + Review
- Analyze CloudWatch Logs Insights queries and X-Ray traces
- Practice full-length timed question sets under exam conditions
- Revisit weak domains identified during practice
This weighting-based approach, rather than a generic even split across topics, is the core idea behind our DVA-C02 study guide for passing on the first attempt. Pair structured review with realistic timed practice on our practice test platform so you get comfortable with the multiple response question style before exam day - that format trips up more candidates than the content itself.
Key Takeaway
Allocate study time proportionally to domain weight: heaviest focus on Development with AWS Services (32%), lightest on Troubleshooting and Optimization (18%), but never skip a domain entirely.
