A developer is creating an application. New users of the application must be able to create an account and register by using their own social media accounts.
Which AWS service or resource should the developer use to meet these requirements?

  1. IAM role
  2. Amazon Cognito identity pools
  3. Amazon Cognito user pools
  4. AWS Directory Service

Answer(s): C



A social media application uses the AWS SDK for JavaScript on the frontend to get user credentials from AWS Security Token Service (AWS STS). The application stores its assets in an Amazon S3 bucket. The application serves its content by using an Amazon CloudFront distribution with the origin set to the S3 bucket.
The credentials for the role that the application assumes to make the SDK calls are stored in plaintext in a JSON file within the application code. The developer needs to implement a solution that will allow the application to get user credentials without having any credentials hardcoded in the application code.
Which solution will meet these requirements?

  1. Add a Lambda@Edge function to the distribution. Invoke the function on viewer request. Add permissions to the function's execution role to allow the function to access AWS STS. Move all SDK calls from the frontend into the function.
  2. Add a CloudFront function to the distribution. Invoke the function on viewer request. Add permissions to the function's execution role to allow the function to access AWS STS. Move all SDK calls from the frontend into the function.
  3. Add a Lambda@Edge function to the distribution. Invoke the function on viewer request. Move the credentials from the JSON file into the function. Move all SDK calls from the frontend into the function.
  4. Add a CloudFront function to the distribution. Invoke the function on viewer request. Move the credentials from the JSON file into the function. Move all SDK calls from the frontend into the function.

Answer(s): A



An ecommerce website uses an AWS Lambda function and an Amazon RDS for MySQL database for an order fulfillment service. The service needs to return order confirmation immediately.
During a marketing campaign that caused an increase in the number of orders, the website's operations team noticed errors for “too many connections” from Amazon RDS. However, the RDS DB cluster metrics are healthy. CPU and memory capacity are still available.
What should a developer do to resolve the errors?

  1. Initialize the database connection outside the handler function. Increase the max_user_connections value on the parameter group of the DB cluster. Restart the DB cluster.
  2. Initialize the database connection outside the handler function. Use RDS Proxy instead of connecting directly to the DB cluster.
  3. Use Amazon Simple Queue Service (Amazon SQS) FIFO queues to queue the orders. Ingest the orders into the database. Set the Lambda function's concurrency to a value that equals the number of available database connections.
  4. Use Amazon Simple Queue Service (Amazon SQS) FIFO queues to queue the orders. Ingest the orders into the database. Set the Lambda function's concurrency to a value that is less than the number of available database connections.

Answer(s): B



A company stores its data in data tables in a series of Amazon S3 buckets. The company received an alert that customer credit card information might have been exposed in a data table on one of the company's public applications. A developer needs to identify all potential exposures within the application environment.
Which solution will meet these requirements?

  1. Use Amazon Athena to run a job on the S3 buckets that contain the affected data. Filter the findings by using the SensitiveData:S3Object/Personal finding type.
  2. Use Amazon Macie to run a job on the S3 buckets that contain the affected data. Filter the findings by using the SensitiveData:S3Object/Financial finding type.
  3. Use Amazon Macie to run a job on the S3 buckets that contain the affected data. Filter the findings by using the SensitiveData:S3Object/Personal finding type.
  4. Use Amazon Athena to run a job on the S3 buckets that contain the affected data. Filter the findings by using the SensitiveData:S3Object/Financial finding type.

Answer(s): B



A software company is launching a multimedia application. The application will allow guest users to access sample content before the users decide if they want to create an account to gain full access. The company wants to implement an authentication process that can identify users who have already created an account. The company also needs to keep track of the number of guest users who eventually create an account.
Which combination of steps will meet these requirements? (Choose two.)

  1. Create an Amazon Cognito user pool. Configure the user pool to allow unauthenticated users. Exchange user tokens for temporary credentials that allow authenticated users to assume a role.
  2. Create an Amazon Cognito identity pool. Configure the identity pool to allow unauthenticated users. Exchange unique identity for temporary credentials that allow all users to assume a role.
  3. Create an Amazon CloudFront distribution. Configure the distribution to allow unauthenticated users. Exchange user tokens for temporary credentials that allow all users to assume a role.
  4. Create a role for authenticated users that allows access to all content. Create a role for unauthenticated users that allows access to only the sample content.
  5. Allow all users to access the sample content by default. Create a role for authenticated users that allows access to the other content.

Answer(s): B,D

AWS Certified Developer - Associate DVA-C02 Exam Discussions & Posts

Amazon AWS Certified Developer - Associate DVA-C02: Skills Tested, Job Roles, and Study Tips

The AWS Certified Developer - Associate DVA-C02 certification is designed for individuals who perform a developer role and have one or more years of hands-on experience developing and maintaining applications on the Amazon Web Services platform. This certification validates a candidate's ability to demonstrate an in-depth understanding of core AWS services, uses, and basic AWS architecture best practices. Employers across various industries, from startups to large enterprises, seek professionals with this credential because it confirms the holder can write, deploy, and debug cloud-based applications using AWS. By achieving this certification, developers prove they possess the technical proficiency required to build secure and scalable cloud applications, which is a critical function in modern software engineering teams.

What the AWS Certified Developer - Associate DVA-C02 Exam Covers

The exam evaluates a candidate's proficiency across several critical domains, including development with AWS services, security, deployment, and troubleshooting and optimization. In practical terms, this means a developer must understand how to write code that interacts with AWS services like Amazon DynamoDB, Amazon SQS, and Amazon SNS, while also implementing appropriate security measures such as IAM policies and encryption. Deployment is a major focus, requiring knowledge of CI/CD pipelines, AWS Elastic Beanstalk, and AWS CloudFormation to automate the release of software. Troubleshooting and optimization require the ability to identify performance bottlenecks and resolve issues using tools like Amazon CloudWatch and AWS X-Ray. Our practice questions are structured to mirror these real-world scenarios, ensuring that candidates are tested on their ability to apply these concepts rather than just recalling definitions.

Among these domains, the development with AWS services and troubleshooting areas are often considered the most technically demanding by candidates. These sections require a deep understanding of how different services interact within an application architecture, often presenting complex scenarios where multiple services must be configured correctly to achieve a specific outcome. Candidates must demonstrate not only knowledge of individual service features but also the ability to diagnose why an application might be failing or underperforming in a cloud environment. This level of technical depth necessitates consistent practice, as the exam frequently tests the nuances of service limits, API calls, and integration patterns that are only mastered through hands-on experience.
