A movie fan club hosts a serverless web application in an Amazon S3 bucket. The application uses an AWS Lambda function that is exposed by an Amazon API Gateway API. The function queries an Amazon DynamoDB table to list actors sorted by movie. In the DynamoDB table. Actor is the primary key, Movie is the sort key, and Role and Year are attributes.
In the web application, a developer wants to add a page that is named Phase 1 that lists only the movies that were released between 2008 and 2012. The developer needs to fetch the Phase 1 items in a way that minimizes the impact on the DynamoDB table.
Which solution will meet these requirements?
A. Create a global secondary index (GSl) with the Year attribute as the sort key. Create a Lambda function to return the results from a new method in the API.
B. Design a Lambda function that scans the DynamoDB table and filters the results for the Phase 1 items. Invoke the function from a new method in the API.
C. Use a DynamoDB stream to send items that are filtered by Year to a new DynamoDB table. Invoke a Lambda function from a new method in the API.
D. Set up an Amazon CloudFront distribution. Create a Lambda@Edge function to filter the items that are returned from the API request.
A developer wants to migrate a Windows .NET application that is running on IIS with a Microsoft SQL Server database to AWS. The developer does not want to think about provisioning and managing the infrastructure. What should the developer do to migrate the application with the LEAST amount of effort?
A. Launch Amazon EC2 instances for Windows Server. Back up and restore the database to Amazon RDS. Deploy the web application to the new EC2 instances
B. Back up and restore the database to Amazon RDS. Use the .NET Migration Assistant for AWS Elastic Beanstalk to migrate the web application to a preconfigured solution stack that Elastic Beanstalk provides.
C. Migrate the database to Amazon DynamoDB Use Amazon API Gateway and AWS Lambda to create a web application interface that is hosted in an Amazon S3 bucket.
D. Containerize the application on premises. Push the image to Amazon Elastic Container Registry (Amazon ECR). Create an AWS CloudFormation template to deploy the application
A developer has written an application that uses Amazon API Gateway and AWS Lambda The developer needs to configure the application so that the developer can visualize the application's components and Identify performance bottlenecks.
What should the developer do to meet these requirements?
A. Enable AWS X-Ray tracing on the API Gateway stage
B. Enable AWS X-Ray tracing on the API Gateway methods
C. Enable Amazon CloudWatch Logs for API Gateway
D. Enable Amazon CloudWatch Logs for Lambda
A developer at a company recently created a serverless application to process and show data from business reports. The application's user interface (Ul) allow users to select and start processing the files. The Ul displays a message when the result is available to view. The application uses AWS Step Functions with A Lambda functions "to process the files. The developer used Amazon API Gateway and Lambda functions to create an API to support the Ul.
The company's Ul team reports that the request to process a file is often returning timeout errors because of the size or complexity of the files. The Ul team w< API to provide an immediate response so that the Ul can display a message while the files are being processed. The backend process that is invoked by the A needs to send an email message when the report processing is complete.
What should the developer do to configure the API to meet these requirements?
A. Change the API Gateway route to add an X-Amz-lnvocation-Type header with a static value of 'Event' in the integration request. Deploy the API Gatt stage to apply the changes.
B. Change the configuration of the Lambda function that implements the request to process a file. Configure the maximum age of the event so that the Lambda function will run asynchronously.
C. Change the API Gateway timeout value to match the Lambda function timeout value. Deploy the API Gateway stage to apply the changes.
D. Change the API Gateway route to add an X-Amz-Target header with a static value of 'Async' in the integration request. Deploy the API Gateway stag apply the changes.
A developer deployed an application to an Amazon EC2 instance. The application needs to know the public IPv4 address of the instance. How can the application find this information?
A. Query the instance metadata from http://169.254.169.254/latest/meta-data/.
B. Query the instance user data from http://169.254.169.254/latest/user-data/.
C. Query the Amazon Machine Image (AMI) information from http://169.254.169.254/latest/meta-data/ami/ .
D. Check the hosts file of the operating system.
A data-processing application includes an AWS Lambda function that processes data in several steps. Recently, the function has been reaching the Lambda tii A developer wants to use AWS X-Ray to find out how long each step is taking so that the developer can determine which step is causing the timeout.
Which combination of actions should the developer take to accomplish this goal? (Select TWO.)
A. Modify the application to call the PutMetricData API operation after each processing step. Include the time taken in milliseconds.
B. Use the aws lambda update-function-configuration AWS CLI command to enable active tracing on the Lambda function.
C. Modify the application to record each processing step in an X-Ray subsegment by using the X-Ray software development kit (SDK).
D. Add the xray:PutTraceSegments permission and the xray:PutTelemetryRecords permission to the Lambda function's execution role.
E. Modify the application to put each processing step in a separate Lambda layer. Include all the layers in the Lambda function.
A company is using AWS Elastic Beanstalk to deploy a three-tier application. The application uses an Amazon RDS DB instance as the database tier. The com wants to decouple the DB instance from the Elastic Beanstalk environment.
Which combination of steps should a developer take to meet this requirement? (Select TWO.)
A. Create a new Elastic Beanstalk environment that connects to the DB instance.
B. Create a new DB instance from a snapshot of the previous DB instance.
C. Use the Elastic Beanstalk CLI to decouple the DB instance.
D. Use the AWS CLI to decouple the DB instance.
E. Modify the current Elastic Beanstalk environment to connect to the DB instance.
What are the MINIMUM properties required in the resources section of the AppSpace file for CodeDeploy to deploy the ECS service successfully?
A. name, alias, currentversion, and targetversion
B. TaskDefinition, ContainerName, and PlartformVersion
C. TaskDefinitionContainerName, ContainerPort
D. name, Currentversion, NetworkConfiguration, and Platform Version
An ecommerce application is using Amazon Simple Notification Service (Amazon SNS) with an AWS Lambda subscription to save all new orders into an Amazon DynamoDB table The company wants to record all the orders that are more than a certain amount of money in a separate table The company wants to avoid changes to the processes that post orders to Amazon SNS or the current Lambda function that saves the orders to the DynamoDB table.
How can a developer implement this feature with the LEAST change to the existing application?
A. Create another Lambda subscription with the SNS message attribute value matching a filter option to save the appropriate orders to a separate table
B. Create another SNS topic, and also send orders in that topic Create a Lambda subscription with a numeric value filter option to save the appropriate orders to a separate table
C. Create anotherftambda subscnption with the SNS message numeric value matching a filter option to save the appropriate orders to a separate table
D. Modify the Lambda code to filter the orders and save the appropriate orders to a separate table
While developing an application that runs on Amazon EC2 in an Amazon VPC, a Developer identifies the need for centralized storage of application-level logs.
