Developers must demonstrate comprehensive knowledge of AWS security best practices, ensuring that their solutions maintain high standards of confidentiality, integrity, and access control.
The Security domain covers essential concepts such as identity management, encryption strategies, and secure coding practices. Candidates are expected to understand how to leverage AWS services like AWS Identity and Access Management (IAM), AWS Key Management Service (KMS), AWS Secrets Manager, and other security-related tools to create secure and compliant cloud environments.
The Security domain directly aligns with the exam syllabus by testing candidates' practical skills in implementing security mechanisms. The task statements within this domain cover three primary areas: authentication and authorization implementation, encryption using AWS services, and managing sensitive data in application code. These task statements are designed to evaluate a developer's ability to design and implement secure cloud solutions that protect against potential security vulnerabilities.
Candidates can expect a variety of question types in the exam related to the Security domain, including:
- Multiple-choice questions testing theoretical knowledge of security concepts
- Scenario-based questions that require practical application of security principles
- Problem-solving questions that assess the ability to select appropriate AWS security services
- Questions involving IAM policy design and implementation
- Encryption and key management scenario evaluations
To excel in this domain, candidates should possess the following skills:
- Deep understanding of AWS IAM roles, policies, and permissions
- Knowledge of encryption techniques and AWS encryption services
- Ability to implement secure authentication mechanisms
- Understanding of best practices for managing sensitive data
- Familiarity with AWS security services and their appropriate use cases
The exam will test candidates' ability to not just understand security concepts, but to practically apply them in real-world cloud development scenarios. Candidates should focus on hands-on experience and practical implementation of security measures in AWS environments.
The Deployment domain in the AWS Certified Developer - Associate exam focuses on understanding how developers can effectively prepare, test, and deploy applications using AWS services. This domain emphasizes the entire application lifecycle management, from artifact preparation to automated deployment and testing strategies. Developers must demonstrate proficiency in using AWS tools and services to create robust, scalable, and efficient deployment pipelines that ensure smooth application delivery.
This domain covers critical aspects of modern cloud-based software development, including artifact management, environment testing, continuous integration and continuous deployment (CI/CD) processes, and leveraging AWS-native services for streamlined application releases. The skills tested in this domain reflect real-world scenarios where developers need to implement reliable and repeatable deployment methodologies.
The Deployment domain directly relates to the exam syllabus by testing candidates' practical knowledge of AWS deployment tools and best practices. Specifically, the task statements cover key areas such as:
- Preparing application artifacts for AWS deployment
- Creating and managing development environments
- Implementing automated deployment testing
- Utilizing AWS CI/CD services like AWS CodePipeline, CodeBuild, and CodeDeploy
Candidates can expect a variety of question types in this domain, including:
- Multiple-choice questions testing theoretical knowledge of deployment concepts
- Scenario-based questions that require selecting the most appropriate AWS service for a specific deployment challenge
- Questions that assess understanding of CI/CD pipeline configuration
- Practical application scenarios involving artifact management and automated testing
The exam will require candidates to demonstrate intermediate to advanced skills in:
- Understanding AWS deployment services and their interactions
- Configuring automated deployment pipelines
- Implementing testing strategies in cloud environments
- Selecting appropriate deployment techniques based on application requirements
To excel in this domain, candidates should have hands-on experience with AWS deployment tools, understand infrastructure-as-code principles, and be familiar with continuous integration and deployment methodologies. Practical experience with services like AWS Elastic Beanstalk, AWS CodeDeploy, and AWS CodePipeline will be crucial for success.
Domain 4: Troubleshooting and Optimization is a critical area in the AWS Certified Developer - Associate exam that focuses on a developer's ability to diagnose, analyze, and improve application performance and reliability within AWS environments. This domain tests candidates' skills in identifying root causes of issues, implementing observability mechanisms, and leveraging AWS services to optimize application performance and efficiency.
The topic encompasses three key task statements that are essential for AWS developers: conducting root cause analysis, instrumenting code for observability, and optimizing applications using AWS services and features. These skills are crucial for maintaining high-performance, reliable, and scalable cloud applications that meet enterprise-level requirements.
In the AWS Certified Developer - Associate (DVA-C02) exam syllabus, this domain represents a significant portion of the overall assessment, typically accounting for approximately 20-25% of the total exam content. The subtopics directly align with real-world developer responsibilities, testing practical skills in troubleshooting, monitoring, and performance optimization.
Candidates can expect a variety of question types in this domain, including:
