질문 # 808
A company is creating an AWS Step Functions state machine to run a set of tests for an application. The tests need to run when a specific AWS CloudFormation stack is deployed. Which combination of steps will meet these requirements? (Choose two.)

A. Create an AWS Lambda function to invoke the state machine.
B. Create a pipe in Amazon EventBridge Pipes that has a source of the default event bus. Set the Lambda function as a target. Filter on a detail type of CloudFormation stack status change, a status of UPDATE_IN_PROGRESS, and the stack ID of the CloudFormation stack.
C. Create a pipe in Amazon EventBridge Pipes that has a source of the EventBridge rule. Set the state machine as a target.
D. Create an Amazon EventBridge rule on the default bus that matches on a detail type of CloudFormation stack status change, a status of UPDATE_IN_PROGRESS, and the stack ID of the CloudFormation stack.
E. Add the state machine as a target of the EventBridge rule.

정답：D,E

질문 # 809
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 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.
C. 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.
D. 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.

정답：B

설명：
Step Functions Retriers: Retriers provide a built-in way to gracefully handle transient errors within State Machines. Here's how to use them:
Directly attach a retrier to the problematic 'GetResource' task.
Configure the retrier:
ErrorEquals: Set this to ['TooManyRequestsException'] to target the specific error.
IntervalSeconds: Set to 10 for the desired retry delay.
MaxAttempts: Set to 1, as you want only one retry attempt.
Error Handling:
Upon 'TooManyRequestsException', the retrier triggers the task again after 10 seconds.
On a second failure, Step Functions moves to the next state or fails the workflow, as per your design.
'IllegalArgumentException' causes error propagation as intended.

질문 # 810
A company has a web application that contains an Amazon API Gateway REST API. A developer has created an AWS CloudFormation template for the initial deployment of the application. The developer has deployed the application successfully as part of an AWS CodePipeline continuous integration and continuous delivery (CI/CD) process. All resources and methods are available through the deployed stage endpoint.
The CloudFormation template contains the following resource types:
AWS::ApiGateway::RestApi
AWS::ApiGateway::Resource
AWS::ApiGateway::Method
AWS::ApiGateway::Stage
AWS::ApiGateway::Deployment
The developer adds a new resource to the REST API with additional methods and redeploys the template. CloudFormation reports that the deployment is successful and that the stack is in the UPDATE_COMPLETE state. However, calls to all new methods are returning 404 (Not Found) errors.
What should the developer do to make the new methods available?

A. Add an AWS CodeBuild stage to CodePipeline to run the aws apigateway create-deployment AWS CLI command.
B. Specify the disable-rollback option during the update-stack operation.
C. Add an action to CodePipeline to run the aws cloudfront create-invalidation AWS CLI command.
D. Unset the CloudFormation stack failure options.

정답：A

질문 # 811
A developer uses AWS CloudFormation to deploy an Amazon API Gateway API and an AWS Step Functions state machine. The state machine must reference the API Gateway API after the CloudFormation template is deployed. The developer needs a solution that uses the state machine to reference the API Gateway endpoint.
Which solution will meet these requirements MOST cost-effectively?

A. Configure the CloudFormation template to store the API endpoint in an environment variable for the AWS::StepFunctions::StateMachine resource. Configure the state machine to reference the environment variable.
B. Configure the CloudFormation template to store the API endpoint in a standard AWS::SecretsManager::Secret resource. Configure the state machine to reference the resource.
C. Configure the CloudFormation template to reference the API endpoint in the DefinitionSubstitutions property for the AWS::StepFunctions::StateMachine resource.
D. Configure the CloudFormation template to store the API endpoint in a standard AWS::AppConfig::ConfigurationProfile resource. Configure the state machine to reference the resource.

정답：C

질문 # 812
A company needs to harden its container images before the images are in a running state. The company's application uses Amazon Elastic Container Registry (Amazon ECR) as an image registry. Amazon Elastic Kubernetes Service (Amazon EKS) for compute, and an AWS CodePipeline pipeline that orchestrates a continuous integration and continuous delivery (CI/CD) workflow.
Dynamic application security testing occurs in the final stage of the pipeline after a new image is deployed to a development namespace in the EKS cluster. A developer needs to place an analysis stage before this deployment to analyze the container image earlier in the CI/CD pipeline.
Which solution will meet these requirements with the MOST operational efficiency?

A. Create a new CodePipeline stage that occurs after the container image is built. Configure ECR basic image scanning to scan on image push. Use an AWS Lambda function as the action provider. Configure the Lambda function to check the scan results and to fail the pipeline if there are findings.
B. Add an action to the deployment stage of the pipeline so that the action occurs before the deployment to the EKS cluster. Configure ECR basic image scanning to scan on image push. Use an AWS Lambda function as the action provider. Configure the Lambda function to check the scan results and to fail the pipeline if there are findings.
C. Create a new CodePipeline stage that occurs after source code has been retrieved from its repository. Run a security scanner on the latest revision of the source code. Fail the pipeline if there are findings.
D. Build the container image and run the docker scan command locally. Mitigate any findings before pushing changes to the source code repository. Write a pre-commit hook that enforces the use of this workflow before commit.

정답：B
