6 Practice Exams | AWS Certified Developer – Associate

Prepare with confidence for the AWS Certified Developer – Associate (DVA-C02) exam using the most comprehensive practice test resource available. This course delivers 1,500 unique, high-quality multiple-choice questions meticulously designed to mirror the real exam’s depth, structure, and evolving content. Every question includes detailed explanations written by AWS-certified professionals, ensuring you don’t just memorize answers—you master the why behind each concept. Whether you’re a developer, solutions architect, or cloud engineer, this course transforms theoretical knowledge into actionable exam readiness.

Why This Course Stands Out

Unlike generic practice tests, this course is structured around the official AWS Certified Developer – Associate exam blueprint (DVA-C02). Each of the 6 full-length practice exams (250 questions each) covers critical domains with surgical precision, ensuring no topic is overlooked. You’ll gain fluency in:

Section 1: Development with AWS Services

Master SDK/CLI integration, EC2 metadata patterns, S3 API operations, and service-to-service communication strategies essential for building AWS-native applications.

Section 2: Serverless Application Development

Dive deep into Lambda optimization, API Gateway configurations, Step Functions workflows, and EventBridge event routing—the core of modern AWS development.

Section 3: Security & Identity Management

Implement IAM policies, Cognito authentication, KMS encryption, and network security controls following AWS security best practices.

Section 4: Deployment & CI/CD

Automate infrastructure with CloudFormation, CodePipeline, and Elastic Beanstalk while mastering blue/green deployment patterns.

Section 5: Databases & Storage

Optimize DynamoDB throughput, configure RDS/Aurora, leverage ElastiCache, and design resilient messaging systems with SQS/SNS.

Section 6: Monitoring, Troubleshooting & Optimization

Diagnose issues using CloudWatch metrics, X-Ray traces, and cost/performance optimization techniques for production workloads.

Sample Practice Questions (with Explanations)

Question 1
You are developing a latency-sensitive application using AWS Lambda. Users report intermittent delays during initial requests. Which solution MOST effectively mitigates this issue?
A) Increase the Lambda function timeout
B) Configure Provisioned Concurrency
C) Use Amazon CloudFront caching
D) Enable Lambda function versioning

Correct Answer: B
Explanation: Provisioned Concurrency pre-initializes a specified number of execution environments, eliminating cold start delays for latency-sensitive applications. Option A (timeout) addresses long-running functions but not initialization delays. Option C (CloudFront) caches static content but doesn’t affect Lambda initialization. Option D (versioning) manages deployment versions but doesn’t impact cold starts. AWS documentation explicitly identifies Provisioned Concurrency as the solution for predictable initialization latency.

Question 2
Your DynamoDB table experiences throttling during peak writes. The partition key design is optimal, but write capacity units (WCUs) are consistently exhausted. What is the MOST cost-effective strategy?
A) Enable Auto Scaling for write capacity
B) Switch to on-demand capacity mode
C) Implement exponential backoff in the application
D) Add a global secondary index (GSI)

Correct Answer: A
Explanation: Auto Scaling dynamically adjusts provisioned WCUs based on traffic patterns, optimizing cost during predictable peaks. Option B (on-demand) avoids throttling but costs significantly more for consistent high-traffic workloads. Option C (backoff) retries failed requests but doesn’t prevent throttling. Option D (GSI) distributes read load but doesn’t increase write capacity for the base table. AWS best practices recommend Auto Scaling for predictable traffic spikes to balance cost and performance.

Question 3
You need to deploy an AWS CloudFormation stack across multiple AWS accounts. Which feature enables this without manual intervention?
A) Nested Stacks
B) Stack Policies
C) Stack Sets
D) Change Sets

Correct Answer: C
Explanation: CloudFormation Stack Sets deploy stacks across multiple accounts and regions using AWS Organizations, enabling centralized management. Option A (Nested Stacks) organizes templates hierarchically but doesn’t span accounts. Option B (Stack Policies) controls update permissions. Option D (Change Sets) previews template changes. Stack Sets are explicitly designed for multi-account deployments per AWS documentation.
