Amazon DVA-C02 AWS Certified Developer - Associate Exam Exam Practice Test Questions

• Question 1

  A company receives food orders from multiple partners. The company has a microservices application that uses Amazon API Gateway APIs with AWS Lambda integration. Each partner sends orders by calling a customized API that is exposed through API Gateway. The API call invokes a shared Lambda function to process the orders.Partners need to be notified after the Lambda function processes the orders. Each partner must receive updates for only the partner's own orders. The company wants to add new partners in the future with the fewest code changes possible.Which solution will meet these requirements in the MOST scalable way?

  • Create a different Amazon Simple Notification Service (Amazon SNS) topic for each partner. Configure the Lambda function to publish messages for each partner to the partner's SNS topic.
  • Create a different Lambda function for each partner. Configure the Lambda function to notify each partner's service endpoint directly.
  • Create an Amazon Simple Notification Service (Amazon SNS) topic. Configure the Lambda function to publish messages with specific attributes to the SNS topic. Subscribe each partner to the SNS topic. Apply the appropriate filter policy to the topic subscriptions.
  • Create one Amazon Simple Notification Service (Amazon SNS) topic. Subscribe all partners to the SNS topic.

• Question 3

  A company wants to share information with a third party. The third party has an HTTP API endpoint that the company can use to share the information. The company has the required API key to access the HTTP API.The company needs a way to manage the API key by using code. The integration of the API key withthe application code cannot affect application performance. Which solution will meet these requirements MOST securely?

  • Store the API credentials in AWS Secrets Manager. Retrieve the API credentials at runtime by using the AWS SDK. Use the credentials to make the API call.
  • Store the API credentials in a local code variable. Push the code to a secure Git repository. Use the local code variable at runtime to make the API call.
  • Store the API credentials as an object in a private Amazon S3 bucket. Restrict access to the S3 object by using IAM policies. Retrieve the API credentials at runtime by using the AWS SDK. Use the credentials to make the API call.
  • Store the API credentials in an Amazon DynamoDB table. Restrict access to the table by using resource-based policies. Retrieve the API credentials at runtime by using the AWS SDK. Use the credentials to make the API call.

• Question 4

  A developer is creating an application that will store personal health information (PHI). The PHI needs to be encrypted at all times. An encrypted Amazon RDS for MySQL DB instance is storing the data. The developer wants to increase the performance of the application by caching frequentlyaccessed data while adding the ability to sort or rank the cached datasets. Which solution will meet these requirements?

  • Create an Amazon ElastiCache for Redis instance. Enable encryption of data in transit and at rest. Store frequently accessed data in the cache.
  • Create an Amazon ElastiCache for Memcached instance. Enable encryption of data in transit and at rest. Store frequently accessed data in the cache.
  • Create an Amazon RDS for MySQL read replica. Connect to the read replica by using SSL. Configure the read replica to store frequently accessed data.
  • Create an Amazon DynamoDB table and a DynamoDB Accelerator (DAX) cluster for the table. Store frequently accessed data in the DynamoDB table.

The developer wants to add end-to-end testing to the application to eliminate as many bugs as possible before the bugs reach production.Which solution should the developer implement to meet these requirements?

  • Run the amplify add test command in the Amplify CLI.
  • Create unit tests in the application. Deploy the unit tests by using the amplify push command in the Amplify CLI.
  • Add a test phase to the amplify.yml build settings for the application.
  • Add a test phase to the aws-exports.js file for the application.
