Deployment, Provisioning, and Automation

A company uses AWS CodeDeploy to deploy an application to an Auto Scaling group. The deployment strategy is set to CodeDeployDefault.HalfAtATime. The lifecycle hooks for the Auto Scaling group include a test hook that runs during instance launch. During a recent deployment, the deployment failed because the new instances failed the test hook and were not marked as healthy. The SysOps administrator needs to ensure that failed instances are automatically terminated and replaced with new ones from the Auto Scaling group. Which configuration change should the administrator make?

A company uses AWS CodePipeline to automate the deployment of a web application. The pipeline consists of a source stage (AWS CodeCommit) and a deploy stage (AWS CodeDeploy) that deploys to an Auto Scaling group. The SysOps administrator needs to add a stage to run automated unit tests before the deployment proceeds. The tests must be executed in an isolated environment, and if they fail, the pipeline must stop and notify the development team. Which action should the administrator take?

A SysOps administrator uses AWS CloudFormation to deploy infrastructure. The admin has a template that creates an EC2 instance with a custom software stack. The software stack must be installed and configured using PowerShell scripts. The admin wants to minimize operational overhead by automating the creation of an AMI that includes the software stack, and the AMI should be rebuilt on a weekly basis to include the latest security patches. Which combination of AWS services should be used?

A company uses AWS CodePipeline to deploy a web application. The pipeline includes a stage that runs a database migration script. The SysOps administrator wants to ensure that if the migration script fails, the entire pipeline stops and the previous version of the application remains deployed.

The administrator needs to update the stack to change the EC2 instance type. The administrator wants to ensure that the update does not accidentally replace the RDS database. Which CloudFormation feature should the administrator use to protect the RDS resource from being replaced during the stack update?

A company uses AWS CodeDeploy to deploy a web application to a fleet of Amazon EC2 instances. The SysOps administrator needs to implement a deployment strategy that ensures zero downtime by creating a new set of instances alongside the current ones, then gradually shifting traffic to the new instances after they pass health checks. If a problem is detected, traffic can be instantly redirected back to the original instances. Which deployment configuration should the administrator use?

A SysOps administrator uses AWS CloudFormation to deploy a stack that includes an Amazon EC2 instance and a security group. The administrator wants to ensure that when the stack is updated, the security group is not accidentally replaced if its properties change. The administrator wants to receive a failure if an update would require replacement of the security group. Which CloudFormation feature should the administrator use?

A CloudFormation stack manages an RDS database, an S3 bucket, and several Lambda functions. During a recent stack update, a property change caused CloudFormation to replace the RDS instance, deleting the database and re-creating it — resulting in data loss. The team wants to prevent any future stack update from replacing or deleting the RDS instance without an explicit override. What CloudFormation feature accomplishes this?

A containerized API runs on Amazon ECS with an Application Load Balancer. The team wants to deploy new container versions with zero downtime, automatically route traffic to the new version only after health checks pass, and automatically roll back if error rates spike within 10 minutes of the shift.
