Amazon DVA-C02 Practice Test - Questions Answers, Page 25

A company maintains a REST service using Amazon API Gateway and the API Gateway native API key validation. The company recently launched a new registration page, which allows users to sign up for the service. The registration page creates a new API key using CreateApiKey and sends the new key to the user. When the user attempts to call the API using this key. the user receives a 403 Forbidden error. Existing users are unaffected and can still call the API.

What code updates will grant these new users access to the API?

A developer is building a microservice that uses AWS Lambda to process messages from an Amazon Simple Queue Service (Amazon SQS) standard queue. The Lambda function calls external APIs to enrich the SOS message data before loading the data into an Amazon Redshift data warehouse. The SOS queue must handle a maximum of 1.000 messages per second.

During initial testing, the Lambda function repeatedly inserted duplicate data into the Amazon Redshift table. The duplicate data led to a problem with data analysis. All duplicate messages were submitted to the queue within 1 minute of each other.

How should the developer resolve this issue?

A company launched an online portal to announce a new product that the company will release in 6 months. The portal requests that users enter an email address to receive communications about the product. The company needs to create a REST API that will store the email addresses in Amazon DynamoDB.

A developer has created an AWS Lambda function that can store the email addresses. The developer will deploy the Lambda function by using the AWS Serverless Application Model (AWS SAM). The developer must provide access to the Lambda function over HTTP.

Which solutions will meet these requirements with the LEAST additional configuration? (Select TWO.)

A developer has created a large AWS Lambda function. Deployment of the function Is failing because of an InvalidParameterValueException error. The error message indicates that the unzipped size of the function exceeds the maximum supported value.

Which actions can the developer take to resolve this error? (Select TWO.)

A developer is creating a new batch application that will run on an Amazon EC2 instance. The application requires read access to an Amazon S3 bucket. The developer needs to follow security best practices to grant S3 read access to the application.

Which solution meets these requirements?

An 1AM role is attached to an Amazon EC2 instance that explicitly denies access to all Amazon S3 API actions. The EC2 instance credentials file specifies the 1AM access key and secret access key, which allow full administrative access.

Given that multiple modes of 1AM access are present for this EC2 instance, which of the following is correct?

A developer is writing unit tests tor a new application that will be deployed on AWS. The developer wants to validate all pull requests with unit tests and merge the code with the main branch only when all tests pass

The developer stores the code in AWS CodeCommit and sets up AWS CodeBuild to run the unit tests. The developer creates an AWS Lambda function to start the CodeBuild task. The developer needs to identify the CodeCommit events in an Amazon EventBridge event that can invoke the Lambda function when a pull request is created or updated.

Which CodeCommit event will meet these requirements?

A company has a website that displays a daily newsletter. When a user visits the website, an AWS Lambda function processes the browser's request and queries the company's on-premises database to obtain the current newsletter. The newsletters are stored in English. The Lambda function uses the Amazon Translate TranslateText API operation to translate the newsletters, and the translation is displayed to the user.

Due to an increase in popularity, the website's response time has slowed. The database is overloaded. The company cannot change the database and needs a solution that improves the response time of the Lambda function.

Which solution meets these requirements?

A developer creates an AWS Lambda function that is written in Java. During testing, the Lambda function does not work how the developer expected. The developer wants to use tracing capabilities to troubleshoot the problem.

Which AWS service should the developer use to accomplish this goal?
