A company uses AWS CodePipeline and AWS CodeDeploy to deploy application code to Amazon EC2 instances. The EC2 instances send application and CodeDeploy logs to Amazon CloudWatch.
Recently, the company manually rolled back a deployment due to application errors. The company wants to automate the rollback process when application errors occur.
Which solution meets these requirements?
A Create a CloudWatch metric based on the application logs. Create a CloudWatch alarm based on the metric that will activate when application errors occur. Change the deployment group settings to use the CloudWatch alarm configuration. Configure the deployment group to use an auto rollback configuration. B Configure a CloudWatch alarm that uses a custom metric for application errors that are recorded in the CodeDeploy agent logs. Configure the current deployment to use the CloudWatch alarm for its alarm configuration. Configure the deployment to use an auto rollback configuration. C Create an AWS Lambda function that will create a new deployment by using the last successful application deployment. Create an Amazon EventBridge rule that matches events from CodeDeploy that have a deployment status of FAILURE. Configure the EventBridge rule to target the Lambda function. D Create an AWS Lambda function that will create a new deployment group for the application deployment. Create a CloudWatch alarm based on metrics from the application logs. Configure the alarm to activate when an application error occurs on an EC2 instance. Configure the CloudWatch alarm to invoke the Lambda function.
