How should the SysOps administrator meet these requirements?
Activate the instance scale-in protection setting for the Auto Scaling group. Invoke the Lambda function through Amazon EventBridge (Amazon CloudWatch Events).
Activate the instance scale-in protection setting for the Auto Scaling group. Invoke the Lambda function through Amazon Route 53.
Add a lifecycle hook to the Auto Scaling group to invoke the Lambda function through Amazon EventBridge (Amazon CloudWatch Events).
Add a lifecycle hook to the Auto Scaling group to invoke the Lambda function through Amazon Route 53.
Explanations:
Activating the instance scale-in protection prevents Auto Scaling from terminating instances. However, invoking a Lambda function through Amazon EventBridge (formerly CloudWatch Events) requires a lifecycle hook, not just scale-in protection.
Activating the instance scale-in protection prevents Auto Scaling from terminating instances. Amazon Route 53 is not used for invoking Lambda functions in this context.
Adding a lifecycle hook to the Auto Scaling group allows invoking a Lambda function when an instance is terminating. EventBridge can be used to trigger the Lambda function based on lifecycle events.
Adding a lifecycle hook allows invoking a Lambda function, but Route 53 is not the correct service for this task. EventBridge (CloudWatch Events) is used for lifecycle event-based triggers.
As I recall, the answer is:
Add a lifecycle hook to the Auto Scaling group to invoke the Lambda function through Amazon EventBridge (Amazon CloudWatch Events).
