The AWS Certified Developer – Associate exam consists of multiple-choice and multiple-answer questions that assess your understanding and ability to use AWS services to build, deploy, and manage applications. The exam has the following structure:
- Number of Questions: 65 questions.
- Duration: 130 minutes.
- Question Format: Multiple-choice and multiple-answer questions.
- Passing Score: AWS does not publish the exact passing score, but a score of 70% or higher is typically required to pass.
- Cost: The exam costs USD 150.
- Languages: The exam is in English, Japanese, Korean, and Simplified Chinese.
The questions test your ability to solve real-world problems and apply best practices when developing cloud-based applications. These problems will involve theoretical knowledge and practical application of AWS services.
Key Domains and Exam Objectives
The exam is divided into four key domains that represent the knowledge areas you need to master for the certification:
Deployment (22%):- Develop and deploy AWS-based applications using services like Elastic Beanstalk, Lambda, and EC2.
- Utilize AWS tools like CloudFormation and CodeDeploy for continuous integration and deployment (CI/CD). Security (26%):
- Implement security best practices for AWS development, such as using IAM roles and policies, securing application data with encryption, and managing API access through API Gateway. Development (30%):
- Understand how to write and debug code for AWS applications, including working with AWS SDKs, APIs, and CLI tools.
- Work with serverless architectures using AWS services such as AWS Lambda and API Gateway. Refactoring (20%):
- Optimize AWS applications for performance, cost, and scalability. This includes leveraging Elastic Load Balancing (ELB), Auto Scaling, and Amazon CloudWatch for monitoring.
Understanding the domains and their objectives will help guide your study plan and exam preparation.
AWS Compute Services (EC2, Lambda, Elastic Beanstalk)
Amazon EC2 (Elastic Compute Cloud)EC2 is one of the foundational services for running virtual machines on AWS. As a developer, you’ll use EC2 instances to host applications, scale resources, and handle variable workloads. Key concepts to understand include:
- EC2 instance types and families.
- Amazon Machine Images (AMIs).
- EC2 Auto Scaling.
- Security groups and networking. AWS Lambda
- How Lambda works with events from other AWS services like S3, DynamoDB, and API Gateway.
- Managing Lambda functions using the AWS Management Console, CLI, and SDKs.
- Lambda function resource management and execution time limits. Elastic Beanstalk
- Deploy applications to Elastic Beanstalk environments (e.g., web servers, APIs).
- Configure environment settings and manage application versions.
Lambda allows you to run code without provisioning or managing servers, making it a core service for serverless applications. You need to understand:
Elastic Beanstalk is a platform-as-a-service (PaaS) solution that simplifies the deployment of web applications and services. As an AWS Developer, it’s essential to know how to:
AWS Storage and Database Services (S3, DynamoDB, RDS)
Amazon S3 (Simple Storage Service)S3 is used to store and manage data on AWS. Understanding S3’s features, such as:
- Buckets, objects, and access control (IAM policies, bucket policies).
- Versioning, lifecycle policies, and event notifications.
- Integration with other AWS services. Amazon DynamoDB
- Set up tables and manage data in DynamoDB.
- Understand DynamoDB Streams for real-time data processing.
- Optimize queries and performance through the correct table design. Amazon RDS (Relational Database Service)
- Launching and managing RDS instances (MySQL, PostgreSQL, SQL Server, etc.).
- RDS backups, snapshots, and scaling.
- Using RDS with EC2 or Lambda for data access.
DynamoDB is a fully managed NoSQL database service. You need to know how to:
RDS provides managed relational databases. Knowledge areas to focus on include:
Security Best Practices in AWS Development
Security is an essential part of AWS development. Key topics include:
- IAM (Identity and Access Management): Configuring IAM roles, policies, and best practices for securing application resources.
- Encryption: Using encryption at rest and in transit with AWS services such as S3, DynamoDB, and RDS.
- API Security: Securing APIs with AWS API Gateway, Cognito and integrating authentication and authorization mechanisms.
- Security Groups and Network ACLs: Managing network security for EC2 instances and services.
Monitoring and Debugging AWS Applications
As a developer, you must understand how to monitor and debug applications running in the AWS environment. Key services include:
- Amazon CloudWatch: Monitoring the performance and health of AWS resources.
- AWS X-Ray: Tracing and debugging distributed applications, especially for Lambda serverless applications.
- AWS CloudTrail: Keeping track of API calls for auditing purposes.
CI/CD and DevOps Tools for AWS Developers
AWS provides a suite of tools that are essential for CI/CD and DevOps workflows, including:
- AWS CodeCommit: A fully managed source control service.
- AWS CodeBuild: Automating the build process.
- AWS CodeDeploy: Automating application deployments.
- AWS CodePipeline: Orchestrating the CI/CD pipeline.
These tools are integrated with AWS services to streamline application development and deployment in a DevOps model.
