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 2

A company is using AWS CodePipeline to automate its release pipeline. AWS CodeDeploy is being used in the pipeline to deploy an application to Amazon Elastic Container Service (Amazon ECS) using the blue/green deployment model. The company wants to implement scripts to test the green version of the application before shifting traffic. These scripts will complete in 5 minutes or less. If errors are discovered during these tests, the application must be rolled back.

Which strategy will meet these requirements?

Options:

A.

Add a stage to the CodePipeline pipeline between the source and deploy stages. Use AWS CodeBuild to create a runtime environment and build commands in the buildspec file to invoke test scripts. If errors are found, use the aws deploy stop-deployment command to stop the deployment.

B.

Add a stage to the CodePipeline pipeline between the source and deploy stages. Use this stage to invoke an AWS Lambda function that will run the test scripts. If errors are found, use the aws deploy stop-deployment command to stop the deployment.

C.

Add a hooks section to the CodeDeploy AppSpec file. Use the AfterAllowTestTraffic lifecycle event to invoke an AWS Lambda function to run the test scripts. If errors are found, exit the Lambda function with an error to initiate rollback.

D.

Add a hooks section to the CodeDeploy AppSpec file. Use the AfterAllowTraffic lifecycle event to invoke the test scripts. If errors are found, use the aws deploy stop-deployment CLI command to stop the deployment.

Question 3

A company uses Amazon Elastic Kubernetes Services (Amazon EKS) to host containerized applications that are available in Amazon Elastic Container Registry (Amazon ECR).

The company currently launches EKS clusters in the company ' s development environment by using the AWS CLI aws eks create-cluster command. The company uses the aws eks create-addon command to install required add-ons. All installed add-ons are currently version compatible with the version of Kubernetes that the company uses. All clusters exclusively use managed node groups for compute capacity.

Some of the EKS clusters require a version upgrade. A DevOps engineer must ensure that upgrades continuously occur within the AWS standard support schedule.

Which solution will meet this requirement with the LEAST operational overhead?

Options:

A.

Run the aws eks update-cluster-version command, providing appropriate arguments such as cluster name and version number.

B.

Enable EKS Auto Mode on all EKS clusters. Remove all existing managed node groups.

C.

Run the eksctl command to upgrade the EKS clusters. Provide appropriate arguments such as cluster name and version number.

D.

Refactor the environment to create EKS clusters by using infrastructure as code (IaC). Upgrade the clusters by using code changes.
