Amazon AWS Certified Developer - Associate 認定 DVA-C02 試験問題 (Q162-Q167):

質問 # 162
A developer has observed an increase in bugs in the AWS Lambda functions that a development team has deployed in its Node is application. To minimize these bugs, the developer wants to impendent automated testing of Lambda functions in an environment that Closely simulates the Lambda environment.
The developer needs to give other developers the ability to run the tests locally. The developer also needs to integrate the tests into the team's continuous integration and continuous delivery (Ct/CO) pipeline before the AWS Cloud Development Kit (AWS COK) deployment.
Which solution will meet these requirements?

  • A. Create sample events based on the Lambda documentation. Create automated test scripts that use the cdk local invoke command to invoke the Lambda functions. Check the response Document the test scripts for the other developers on the team Update the CI/CD pipeline to run the test scripts.
  • B. Install the AWS Serverless Application Model (AWS SAW) CLI tool Use the Sam local generate-event command to generate sample events for me automated tests. Create automated test scripts that use the Sam local invoke command to invoke the Lambda functions. Check the response Document the test scripts tor the other developers on the team Update the CI/CD pipeline to run the test scripts.
  • C. Install a unit testing framework that reproduces the Lambda execution environment. Create sample events based on the Lambda Documentation Invoke the handler function by using a unit testing framework. Check the response Document how to run the unit testing framework for the other developers on the team. Update the OCD pipeline to run the unit testing framework.
  • D. Create sample events based on the Lambda documentation. Create a Docker container from the Node is base image to invoke the Lambda functions. Check the response Document how to run the Docker container for the more developers on the team update the CI/CD pipeline to run the Docker container.

正解：B

解説：
This solution will meet the requirements by using AWS SAM CLI tool, which is a command line tool that lets developers locally build, test, debug, and deploy serverless applications defined by AWS SAM templates. The developer can use sam local generate-event command to generate sample events for different event sources such as API Gateway or S3. The developer can create automated test scripts that use sam local invoke command to invoke Lambda functions locally in an environment that closely simulates Lambda environment.
The developer can check the response from Lambda functions and document how to run the test scripts for other developers on the team. The developer can also update CI/CD pipeline to run these test scripts before deploying with AWS CDK. Option A is not optimal because it will use cdk local invoke command, which does not exist in AWS CDK CLI tool. Option B is not optimal because it will use a unit testing framework that reproduces Lambda execution environment, which may not be accurate or consistent with Lambda environment. Option D is not optimal because it will create a Docker container from Node.js base image to invoke Lambda functions, which may introduce additional overhead and complexity for creating and running Docker containers.

質問 # 163
A team is developing an application that is deployed on Amazon EC2 instances. During testing, the team receives an error. The EC2 instances are unable to access an Amazon S3 bucket.
Which steps should the team take to troubleshoot this issue? (Choose two.)

  • A. Check the S3 Lifecycle policy to validate the permissions that are assigned to the S3 bucket.
  • B. Check whether the policy that is assigned to the IAM role that is attached to the EC2 instances grants access to Amazon S3.
  • C. Check the security groups that are assigned to the EC2 instances. Make sure that a rule is not blocking the access to Amazon S3.
  • D. Check whether the policy that is assigned to the IAM user that is attached to the EC2 instances grants access to Amazon S3.
  • E. Check the S3 bucket policy to validate the access permissions for the S3 bucket.

正解：B、E

解説：
Option A is correct because IAM roles are used to grant permissions to AWS services, such as EC2 instances, to access other AWS services, such as S3 buckets. The policy assigned to the IAM role attached to the EC2 instances should be checked to ensure that it grants access to the S3 bucket.
Option B is also correct because the S3 bucket policy controls access to the S3 bucket. The S3 bucket policy should be checked to ensure that the access permissions are correctly configured.

 

質問 # 164
A team of developed is using an AWS CodePipeline pipeline as a continuous integration and continuous delivery (CI/CD) mechanism for a web application. A developer has written unit tests to programmatically test the functionality of the application code. The unit tests produce a test report that shows the results of each individual check. The developer now wants to run these tests automatically during the CI/CD process.

  • A. Add a new stage to the pipeline. Use AWS CodeBuild as the provider. Add the new stage after the stage that deploys code revisions to the test environment. Write a buildspec that fails the CodeBuild stage if any test does not pass. Use the test reports feature of Codebuild to integrate the report with the CodoBuild console. View the test results in CodeBuild Resolve any issues.
  • B. Write a Git pre-commit hook that runs the test before every commit. Ensure that each developer who is working on the project has the pre-commit hook instated locally. Review the test report and resolve any issues before pushing changes to AWS CodeCommit.
  • C. Add a new stage to the pipeline. Use Jenkins as the provider. Configure CodePipeline to use Jenkins to run the unit tests. Write a Jenkinsfile that fails the stage if any test does not pass. Use the test report plugin for Jenkins to integrate the repot with the Jenkins dashboard. View the test results in Jenkins.
    Resolve any issues.
  • D. Add a new stage to the pipeline. Use AWS CodeBuild at the provider. Add the new stage before the stage that deploys code revisions to the test environment. Write a buildspec that fails the CodeBuild stage it any test does not pass. Use the test reports feature of CodeBuild to integrate the report with the CodeBuild console. View the test results in codeBuild Resolve any issues.

正解：D

解説：
The solution that will meet the requirements is to add a new stage to the pipeline. Use AWS CodeBuild as the provider. Add the new stage before the stage that deploys code revisions to the test environment. Write a buildspec that fails the CodeBuild stage if any test does not pass. Use the test reports feature of CodeBuild to integrate the report with the CodeBuild console. View the test results in CodeBuild. Resolve any issues. This way, the developer can run the unit tests automatically during the CI/CD process and catch any bugs before deploying to the test environment. The developer can also use the test reports feature of CodeBuild to view and analyze the test results in a graphical interface. The other options either involve running the tests manually, running them after deployment, or using a different provider that requires additional configuration and integration.

 

質問 # 165
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 IllegalArgumentException error or a TooManyRequestsException error.
The developer wants the state machine to stop running when the state machine encounters an IllegalArgumentException 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. 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.
  • 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. 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.
  • 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.

正解：C

 

質問 # 166
A developer designed an application on an Amazon EC2 instance. The application makes API requests to objects in an Amazon S3 bucket.

  • B. Add the IAM role to an instance profile. Attach the instance profile to the EC2 instance.
  • C. Create an IAM user that has permissions to the S3 bucket. Add the user to an IAM group.
  • D. Create an IAM role that has permissions to the S3 bucket. Assign the role to an IAM group.
  • E. Create an IAM role that has permissions to the S3 bucket.

正解：B、E
