Question 100

A company is implementing a CI/CD pipeline for an application by using AWS CodePipeline and AWS CodeBuild. The company needs a solution to run unit tests and automatically generate code coverage reports before any code is deployed to production. The CI/CD pipeline execution must fail if the code coverage is less than 80%.

Which solution will meet these requirements?

Options:

A.

Create an AWS Lambda function to run unit tests and generate code coverage reports. Add a Lambda invoke action to a stage in the CodePipeline pipeline. Create an Amazon EventBridge scheduled rule to run hourly to monitor the Lambda function ' s output. Configure the rule to fail the pipeline if coverage is less than 80%.

B.

Create an AWS Step Functions workflow to run unit tests and generate code coverage reports. Add a Step Functions test action to a stage in the CodePipeline pipeline to invoke the workflow. Configure the workflow to fail if the code coverage is less than 80%.

C.

Create a CodeBuild project with a buildspec.yml file that includes commands to run unit tests and generate code coverage reports. Add a CodeBuild test action to a stage in the CodePipeline pipeline. Configure the CodeBuild test action to use the source artifacts from the source action as input. Modify the buildspec.yml file to fail the build if coverage is less than 80%.

D.

Create a CodeBuild project with Jenkins installed. Configure Jenkins to run unit tests and generate code coverage reports. Add a Jenkins test action to a stage in the CodePipeline pipeline. Configure the Jenkins test action to output the coverage report as an output artifact. Configure an approval action to fail the pipeline if code coverage is less than 80%.

Question 101

A DevOps engineer at a company is migrating a statistical analysis application to AWS. The application allows data scientists to model demographic data by using RStudio. The DevOps engineer will host modeling environments for the application in Amazon Elastic Kubernetes Service (Amazon EKS). The DevOps engineer will use Amazon FSx for Lustre and Amazon S3 to provide backend storage.

The DevOps engineer must design and build an infrastructure as code (IaC) solution to manage the underlying resource configurations. The company uses an organization in AWS Organizations to manage multiple AWS accounts. The DevOps engineer must design a highly portable solution that can facilitate sharing across AWS member accounts.

Which solution will meet these requirements with the LEAST administrative overhead?

Options:

A.

Use the AWS Cloud Development Kit (AWS CDK) to deploy and manage the infrastructure. Store the CDK source code in the project’s version control system. Use AWS CodePipeline to automate the deployment and stack updates in production.

B.

Use AWS CloudFormation to manage the infrastructure. Use CloudFormation modules to manage the required services. Publish the services to the CloudFormation registry. Use AWS CodePipeline to automate the deployment and stack updates in production.

C.

Use AWS Serverless Application Model (AWS SAM) to manage the infrastructure. Create an AWS Service Catalog portfolio for the project. Build an AWS SAM template that deploys each required service as a product within the catalog. Share the portfolio and grant access to the portfolio for member accounts.

D.

Use AWS CloudFormation to manage the infrastructure. Use CloudFormation nested stacks to manage the required services. Store the nested stacks in the project’s version control system. Use AWS CodePipeline to automate the deployment and stack updates in production.

Question 102

A DevOps engineer needs to install antivirus software on all Amazon EC2 instances in an AWS account. The EC2 instances run the most recent Amazon Linux version. The solution must detect all instances and use an AWS Systems Manager document to install the software if missing.

Which solution will meet these requirements?

Options:

A.

Create an association in Systems Manager State Manager targeting all managed nodes. Include the software and Systems Manager document.

B.

Use AWS Config with a custom rule to check for antivirus installation. Configure automatic remediation using the Systems Manager document.

C.

Use Amazon Inspector to detect missing software and associate with Systems Manager automation.

D.

Use EventBridge to detect EC2 RunInstances events and trigger SSM automation.

Question 103

A development team manually builds a local artifact. The development team moves the artifact to an Amazon S3 bucket to support an application. The application has a local cache that must be cleared when the development team deploys the application to Amazon EC2 instances. For each deployment, the development team runs a command to clear the cache, download the artifact from the S3 bucket, and unzip the artifact to complete the deployment.

The development team wants to migrate the deployment process to a CI/CD process and to track the progress of each deployment.

Which combination of actions will meet these requirements with the MOST operational efficiency? (Select THREE.)

Options:

A.

Set up an AWS CodeConnections compatible Git repository. Allow developers to merge code into the repository. Use AWS CodeBuild to build an artifact and copy the object into the S3 bucket. Configure CodeBuild to run for every merge into the main branch.

B.

Create a custom script to clear the cache. Specify the script in the BeforeInstall lifecycle hook in the AppSpec file.

C.

Create user data for each EC2 instance that contains the cache clearing script. Test the application after deployment. If the deployment is not successful, then redeploy.

D.

Use AWS CodePipeline to deploy the application. Set up an AWS CodeConnections compatible Git repository. Allow developers to merge code into the repository as a source for the pipeline.

E.

Use AWS CodeBuild to build the artifact and place the artifact in the S3 bucket. Use AWS CodeDeploy to deploy the artifact to EC2 instances.

F.

Use AWS Systems Manager to fetch the artifact from the S3 bucket and to deploy the artifact to all the EC2 instances.
