The Development team has grown substantially in recent months and so has the number of projects that use separate code repositories. The current process involves con guring AWS CodePipeline manually. There have been service limit alerts regarding the number of Amazon S3 buckets that exist.
Which pipeline option will reduce S3 bucket sprawl alerts?

Combine the multiple separate code repositories into a single one, and deploy using an AWS CodePipeline that has logic for each project.
Create new pipelines by using the AWS API or AWS CLI, and con gure them to use a single S3 bucket with separate pre xes for each project.
Create a new pipeline in a different region for each project to bypass the service limits for S3 buckets in a single region.
Create a new pipeline and S3 bucket for each project by using the AWS API or AWS CLI to bypass the service limits for S3 buckets in a single account.

QUESTION: 51

An online company uses Amazon EC2 Auto Scaling extensively to provide an excellent customer experience while minimizing the number of running EC2 instances. The company's self-hosted Puppet environment in the application layer manages the con guration of the instances. The IT manager wants the lowest licensing costs and wants to ensure that whenever the EC2 Auto Scaling group scales down, removed EC2 instances are deregistered from the Puppet master as soon as possible.
How can the requirement be met?

At instance launch time, use EC2 user data to deploy the AWS CodeDeploy agent. Use CodeDeploy to install the Puppet agent. When the Auto Scaling group scales out, run a script to register the newly deployed instances to the Puppet master. When the Auto Scaling group scales in, use the EC2 Auto Scaling EC2_INSTANCE_TERMINATING lifecycle hook to trigger de-registration from the Puppet master.
Bake the AWS CodeDeploy agent into the base AMI. When the Auto Scaling group scales out, use CodeDeploy to install the Puppet agent, and execute a script to register the newly deployed instances to the Puppet master. When the Auto Scaling group scales in, use the CodeDeploy ApplicationStop lifecycle hook to run a script to de-register the instance from the Puppet master.
At instance launch time, use EC2 user data to deploy the AWS CodeDeploy agent. When the Auto Scaling group scales out, use CodeDeploy to install the Puppet agent, and run a script to register the newly deployed instances to the Puppet master. When the Auto Scaling group scales in, use the EC2 user data instance stop script to run a script to de-register the instance from the Puppet master.
Bake the AWS Systems Manager agent into the base AMI. When the Auto Scaling group scales out, use the AWS Systems Manager to install the Puppet agent, and run a script to register the newly deployed instances to the Puppet master. When the Auto Scaling group scales in, use the Systems Manager instance stop lifecycle hook to run a script to de-register the instance from the Puppet master.

Additionally, the data engineering team must be noti ed of all changes to the templates.
What should the company do to accomplish these goals?

Create an AWS Lambda function to deploy the CloudFormation templates in the required order. Use stack policies to alert the data engineering team.
Host the CloudFormation templates in Amazon S3. Use Amazon S3 events to directly trigger CloudFormation updates and Amazon SNS noti cations.
Implement CloudFormation StackSets and use drift detection to trigger update alerts to the data engineering team.
Leverage CloudFormation nested stacks and stack sets for deployments. Use Amazon SNS to notify the data engineering team.
