Question 386

A developer is building an application that includes an AWS Lambda function that is written in .NET Core.
The Lambda function's code needs to interact with Amazon DynamoDB tables and Amazon S3 buckets. The developer must minimize the Lambda function's deployment time and invocation duration.
Which solution will meet these requirements?

A.Increase the Lambda function's memory.
B.Configure the Lambda function to download the AWS SDK for .NET from an S3 bucket at runtime.
C.Include only the AWS SDK for .NET modules for DynamoDB and Amazon S3 in the Lambda function's deployment package.
D.Include the entire AWS SDK for .NET in the Lambda function's deployment package.

Question 387

A developer is using AWS Step Functions to automate a workflow The workflow defines each step as an AWS Lambda function task The developer notices that runs of the Step Functions state machine fail in the GetResource task with either an UlegalArgumentException error or a TooManyRequestsException error The developer wants the state machine to stop running when the state machine encounters an UlegalArgumentException error. The state machine needs to retry the GetResource task one additional time after 10 seconds if the state machine encounters a TooManyRequestsException error. If the second attempt fails, the developer wants the state machine to stop running.
How can the developer implement the Lambda retry functionality without adding unnecessary complexity to the state machine'?

A.Add a Delay task after the GetResource task. Add a catcher to the GetResource task. Configure the catcher with an error type of TooManyRequestsException. Configure the next step to be the Delay task Configure the Delay task to wait for an interval of 10 seconds Configure the next step to be the GetResource task.
B.Add a catcher to the GetResource task Configure the catcher with an error type of TooManyRequestsException. an interval of 10 seconds, and a maximum attempts value of 1. Configure the next step to be the GetResource task.
C.Add a retrier to the GetResource task Configure the retrier with an error type of TooManyRequestsException, an interval of 10 seconds, and a maximum attempts value of 1.
D.Duplicate the GetResource task Rename the new GetResource task to TryAgain Add a catcher to the original GetResource task Configure the catcher with an error type of TooManyRequestsException.Configure the next step to be TryAgain.

Question 388

A developer is migrating an application to Amazon Elastic Kubernetes Service (Amazon EKS). The developer migrates the application to Amazon Elastic Container Registry (Amazon ECR) with an EKS cluster.
As part of the application migration to a new backend, the developer creates a new AWS account. The developer makes configuration changes to the application to point the application to the new AWS account and to use new backend resources. The developer successfully tests the changes within the application by deploying the pipeline.
The Docker image build and the pipeline deployment are successful, but the application is still connecting to the old backend. The developer finds that the application's configuration is still referencing the original EKS cluster and not referencing the new backend resources.
Which reason can explain why the application is not connecting to the new resources?

A.The developer did not successfully create the new AWS account.
B.The developer added a new tag to the Docker image.
C.The developer did not update the Docker image tag to a new version.
D.The developer pushed the changes to a new Docker image tag.

Correct Answer: C

The correct answer is C. The developer did not update the Docker image tag to a new version.
C). The developer did not update the Docker image tag to a new version. This is correct. When deploying an application to Amazon EKS, the developer needs to specify the Docker image tag that contains the application code and configuration. If the developer does not update the Docker image tag to a new version after making changes to the application, the EKS cluster will continue to use the old Docker image tag that references the original backend resources. To fix this issue, the developer should update the Docker image tag to a new version and redeploy the application to the EKS cluster.
A). The developer did not successfully create the new AWS account. This is incorrect. The creation of a new AWS account is not related to the application's connection to the backend resources. The developer can use any AWS account to host the EKS cluster and the backend resources, as long as they have the proper permissions and configurations.
B). The developer added a new tag to the Docker image. This is incorrect. Adding a new tag to the Docker image is not enough to deploy the changes to the application. The developer also needs to update the Docker image tag in the EKS cluster configuration, so that the EKS cluster can pull and run the new Docker image.
D). The developer pushed the changes to a new Docker image tag. This is incorrect. Pushing the changes to a new Docker image tag is not enough to deploy the changes to the application. The developer also needs to update the Docker image tag in the EKS cluster configuration, so that the EKS cluster can pull and run the new Docker image.

Question 389

A banking company is building an application for users to create accounts, view balances, and review recent transactions. The company integrated an Amazon API Gateway REST API with AWS Lambda functions. The company wants to deploy a new version of a Lambda function that gives customers the ability to view their balances. The new version of the function displays customer transaction insights.
The company wants to test the new version with a small group of users before deciding whether to make the feature available for all users. Which solution will meet these requirements with the LEAST disruption to users?

A.Create a canary deployment for the REST API. Gradually increase traffic to the new version of the function. Revert traffic to the old version if issues are detected.
B.Redeploy the REST API stage to use the new version of the function. If issues are detected, update the REST API to point to the previous version of the function.
C.Deploy the new version of the function to a new stage in the REST API. Route traffic to the new stage.
If the new version fails, route traffic to the original stage.
D.Create a new REST API stage for the new version of the function. Create a weighted alias record set in Amazon Route 53 to distribute traffic between the original stage and the new stage.

Question 390

A developer is creating an AWS CloudFormation stack. The stack contains IAM resources with custom names. When the developer tries to deploy the stack, they receive an InsufficientCapabilities error.
What should the developer do to resolve this issue?

A.Specify the CAPABILITY_AUTO_EXPAND capability in the CloudFormation stack.
B.Use an administrators role to deploy IAM resources with CloudFormation.
C.Specify the CAPABILITY_IAM capability in the CloudFormation stack.
D.Specify the CAPABILITY_NAMED_IAM capability in the CloudFormation stack.
